Recursive Language Model Agent

This is the last guide in the series, and we now build on everything that came before. Guide 6 introduced agents: a loop that decides, acts, observes, and repeats. This guide presents a more powerful agent design: one that can spawn a smaller helper agent for sub-tasks, the way a recursive function in CS101 calls itself on a smaller problem.

What Is a Recursive LM Agent?

Imagine an agent that, when faced with too much work, can hand off a sub-task to a smaller helper agent. Each helper has its own budget; the parent waits for the helper's answer and incorporates it. That is the intuition; the rest of this section makes it precise.

A recursive language model agent (RLM agent, "RLM" for short) is an agent A whose forward computation may invoke another language model M' on a strictly smaller subproblem before returning. Formally, A is a function:

A : (query, inputs) -> answer

In English: A takes a question and some inputs, and it returns an answer. The implementation is a loop. On each turn A calls a single tool, run_python_code(code=...), with a small piece of Python code (a "snippet"). The snippet runs in a sandbox, a restricted Python environment, that exposes two helpers, called the recursive primitives llm_query and llm_query_batched, which forward sub-problems to a second language model M'. These primitives (and submit) are callables inside the sandbox, not separate tools: A reaches them only from the code it passes to run_python_code. Whatever the snippet prints or returns becomes an observation, a log line A can read on its next turn, and the loop continues.

The recursion is value-recursive: A does not call itself on the same inputs. Instead, on each turn, A delegates a piece of the inputs to M': a slice of text, a regex match, a single paragraph. ("Projection" in this context just means "a smaller view of the inputs.")

How do we guarantee the loop stops? Termination is enforced externally by three decreasing measures. A decreasing measure is a number that must strictly shrink on every step; once it hits zero, the loop is forced to end. RLM uses three of them at once:

iteration count: how many turns A is allowed,
sub-LM call budget: how many times A can call M',
per-snippet wall clock: how long one snippet may run.

Because each measure decreases on every step, the whole thing must stop eventually.

The construction follows Recursive Language Models (Zhang, Kraska, Khattab, 2025).

Why Bother With This Design?

Suppose the input is very large. Let n be the size of the input in tokens (a token is the model's unit of text, roughly a short word fragment) and k the size of the question. When n is huge, a whole book, a long log file, three costs grow with n:

Prompt cost. The price of one LM call grows roughly linearly in prompt length. A 200,000-token prompt is mostly tokens the model never actually needs.
Latency. Most providers cap throughput per input token, so waiting time grows with n, not with the size of the answer.
Recall. Past a model-specific threshold, the model gets worse at finding the right fact inside its own context, the well-known "lost in the middle" effect, even when the fact is present.

Two standard fixes you might have already met:

Stuffing. Just paste the full input into the prompt. Simple, but pays all three costs every time.
Offline retrieval. Pre-process the input into chunks, store them in a vector index, and retrieve the top few at query time. This is the RAG pipeline from Guide 7. It is cheap at query time, but the chunk size and the embedding model are picked before the question is known, which puts a ceiling on how good retrieval can ever be.

RLM is a third option. The primary LM (the orchestrator) is never given the full input. It is given an InputsSummary: a list of field names, types, sizes, and short previews. The full value lives inside a persistent Python sandbox, bound to the variable inputs[field]. On each turn the primary LM writes a Python snippet that decides, conditional on the question and on what it has already learned, which slice of the input is worth a sub-LM call.

The key win: the chunking is chosen after the question is known, by code that the model itself wrote.

flowchart TD
    A["Long input and query"] --> S["InputsSummary (previews + sizes)"]
    S --> P["Primary LM"]
    P --> C["Python snippet"]
    C --> X["Sandbox: inputs[field] holds full value"]
    X --> Q{"semantic work?"}
    Q -- "yes" --> L["llm_query / llm_query_batched"]
    Q -- "no"  --> R["Pure code (regex, slicing, set ops)"]
    L --> O["Observation"]
    R --> O
    O --> P
    P -- "done" --> SU["submit(result)"]

Recall: an invariant is a property that holds at every step of the loop. Here, the invariant is: the primary LM's context contains only the summary, the catalog of available tools, and the accumulated trajectory (the running log of past snippets and observations). Each sub-LM call sees only the small piece of text the snippet explicitly hands it. A hard cap on the number of sub-LM calls per agent(...) invocation bounds the total cost.

A Minimal Example

import synalinks

class Doc(synalinks.DataModel):
    text: str

class Answer(synalinks.DataModel):
    answer: str

primary = synalinks.LanguageModel(model="vllm/Qwen/Qwen3.8-27B")

inputs = synalinks.Input(data_model=Doc)
outputs = await synalinks.RLM(
    data_model=Answer,
    language_model=primary,
)(inputs)
agent = synalinks.Program(inputs=inputs, outputs=outputs)

long_text = open("book.txt").read()
result = await agent(Doc(text=long_text))
print(result.prettify_json())

The whole book.txt lives in the sandbox; the primary LM is given only the field's preview and its length.

Inputs as an External Environment

Think of the input as a library shelf in another room. The model holds an index card listing what books are on the shelf and how long each one is; the books themselves stay on the shelf. Whenever the model needs to actually read a book, it writes a snippet that fetches the right passage by name.

More precisely: let x be the user input. The sandbox sets up a global Python dictionary called inputs so that inputs[field] is the full, untruncated value of x[field]. The primary LM never sees x. It sees only an InputsSummary:

fields:
  - name: text
    type: str
    size: 482917         # full character length
    preview: "Chapter 1...  (first 200 chars)"
    truncated: true

Two consequences of this design:

Read through the binding. Snippets must say inputs[field], not retype text out of the preview. The preview is a lossy view (only the first few hundred characters); the binding inputs[field] is the real, full value. Copying from the preview silently smuggles in truncated data.
Aggregate in code, then query for meaning. Structural questions ("where," "how many," "what shape?") have deterministic answers and should be handled by Python: regular expressions (regex, pattern matching on strings), slicing (taking sub-ranges), set operations. Semantic questions ("what does this mean?", "is this about X?") should be answered by llm_query on spans the code has already isolated.

This inverts the usual pipeline: the model is the orchestrator and stays small; the data is the environment and stays external.

The Two Recursive Primitives

A primitive here means a built-in helper function the snippet can call. Besides submit (which returns the final answer), the sandbox exposes two asynchronous primitives, "asynchronous" meaning they use Python's await so several calls can run concurrently.

`llm_query(prompt)`

async def main():
    out = await llm_query(prompt="Summarize this paragraph: ...")
    print(out["result"])

asyncio.run(main())

Sends one prompt to the sub-LM (which model that is can be configured; see below) and returns a dict {"result": <text>}. Use it for semantic work on a span the code has already pulled out: classify a paragraph, summarize a span, extract names, reformat a quote. Each call decrements the shared budget by one.

`llm_query_batched(prompts)`

async def main():
    out = await llm_query_batched(prompts=[
        "Is this paragraph about finance? <p1>",
        "Is this paragraph about finance? <p2>",
        "Is this paragraph about finance? <p3>",
    ])
    finance = [p for p, label in zip(paragraphs, out["result"]) if "yes" in label.lower()]

asyncio.run(main())

Same idea as llm_query, but sends a list of prompts in parallel using asyncio.gather (a Python construct that fires off several async calls at once and waits for all of them). It returns {"result": [<text-or-error>, ...]} in the same order as the input prompts.

Prefer the batched form over a Python for loop of single llm_query calls. A loop calls the sub-LM m times sequentially and stacks up m latencies one after another; it will run out of the per-snippet timeout long before it runs out of budget. If a single prompt in the batch fails, its slot contains a string of the form "[error] <ExceptionType>: <message>", so check for that prefix before treating an element as real data.

Budget invariant

Picture a small allowance: every sub-LM call costs one coin out of a shared jar. The jar must never go below zero.

Both primitives draw from a single counter c, initialized to max_llm_calls (default 50). On a successful single call, c := c − 1; on a successful batch of size m, c := c − m. Two short-circuit rules preserve the invariant c ≥ 0 (the jar is never overdrawn):

A llm_query call when c == 0 returns immediately with error set, and does not decrement c.
A llm_query_batched(prompts) call where c < len(prompts) returns immediately, all-or-nothing: it never partially fulfils a batch.

In plain words: if you cannot afford the whole batch, you get nothing: the budget is never overshot.

The counter is reset at the start of every agent(...) invocation, so two concurrent invocations don't share a jar.

A llm_query short-circuit reads:

{"result": "", "error": "sub-LM call budget exhausted (50/50). ..."}

A llm_query_batched short-circuit reads:

{"result": [], "error": "sub-LM call budget would be exceeded: 45 + 10 > 50. ..."}

In both cases the model is told to fall back to code-only aggregation. The rule of thumb: always check error before using result.

Adding Your Own Tools

RecursiveLanguageModelAgent accepts a tools= argument. You can plug in your own helper functions, fetch a URL, query a database, hit a search API, and the model can call them from inside its snippets. The names llm_query, llm_query_batched, and submit are reserved; every other tool is bound as a global async function inside the sandbox and can be combined with the recursive primitives in the same snippet.

A note on trust. A tool body runs on the host machine with full Python privileges: filesystem, network, third-party libraries. The sandbox restricts only the snippet itself; once execution crosses into a host-side tool, the sandbox no longer protects you. In practice, each tool is the trust boundary: validate the tool's arguments, scope what it is allowed to touch, and do not expose destructive operations unless your deployment really needs them.

Decorate each tool with @synalinks.saving.register_synalinks_serializable() so that it survives get_config / from_config round-trips (saving and loading the agent):

@synalinks.saving.register_synalinks_serializable()
async def fetch_url(url: str) -> dict:
    """Fetch a URL and return its body.

    Args:
        url (str): the URL to GET.
    """
    import httpx
    async with httpx.AsyncClient() as client:
        resp = await client.get(url)
        return {"status": resp.status_code, "body": resp.text}

agent = synalinks.RLM(
    data_model=Answer,
    language_model=primary,
    sub_language_model=cheap,
    tools=[synalinks.Tool(fetch_url)],
)

Inside a single snippet the LM can now mix real-world side effects with recursive sub-LM work: fetch a page, hand the body to llm_query for classification, then submit the result. Treat every tool the way you'd treat a public web endpoint: validate inputs, restrict filesystem and network access, and don't expose anything destructive unless the deployment really requires it.

Choosing the Sub-LM

sub_language_model defaults to whatever language_model you passed, so by default the same model plays both roles. That is convenient for prototyping but almost always wasteful in production, because the two jobs have very different shapes:

The primary LM plans, writes code, and formats the final structured answer. It needs to be capable, but you only call it a handful of times per run.
The sub-LM answers narrow, local questions: "summarize this paragraph", "is this paragraph about X?". A small, cheap model is usually plenty, and you call it many times per run.

Pass a separate sub_language_model to exploit the asymmetry:

primary = synalinks.LanguageModel(model="vllm/Qwen/Qwen3.8-27B")
cheap   = synalinks.LanguageModel(model="vllm/Qwen/Qwen3.8-27B")

agent = synalinks.RLM(
    data_model=Answer,
    language_model=primary,
    sub_language_model=cheap,
)

A typical RLM run makes dozens of sub-LM calls and just one or two primary-LM turns, so total cost is dominated by the per-call cost of the sub-LM. In short: picking the sub-LM is where most of your money is spent.

Working Rules (in the system prompt)

The default instructions give the model a five-item checklist for how to behave in the loop. Each rule corresponds to a real failure mode this design has hit in practice:

Explore before slicing. On the very first turn, print sample values, lengths, types, and shapes of inputs[field]. A cheap probe (cost: zero sub-LM calls) prevents wasted sub-LM calls on the wrong field.
Code for structure; llm_query for meaning. Regex, slicing, and set operations answer "where" and "how many" deterministically and for free. Reserve the sub-LM for "what does this mean."
Do not retype. Always re-access values via inputs[field], never by copying text out of the preview. The preview is truncated; copies drift away from the truth.
Verify before submitting. If results look empty, zero, or misshapen, spend an extra turn inspecting them before calling submit.
submit is terminal. A snippet runs to completion (so a print near submit does execute), but once submit succeeds the loop ends; that final captured print is never read by the model. Lesson: inspect on one turn, then submit on the next.

You can replace these defaults via the instructions= argument if your task wants a different style, but the defaults are tuned for the long-input, sparse-query case.

Default settings

Setting	Default	Rationale
`max_iterations`	20	Bounds the explore-carve-query-aggregate-submit loop.
`timeout`	60 s	One `llm_query_batched(20)` snippet routinely needs more than 5 s.
`max_llm_calls`	50	Hard ceiling on sub-LM calls per run; surfaced to the LM via `error`.

Override any of them if the workload's measure is known.

RLM versus `FunctionCallingAgent`

FunctionCallingAgent (FCA) is the more common pattern: the LM emits JSON tool calls and gets back JSON results, with the full input sitting in the prompt. The table below compares the two:

Aspect	FunctionCallingAgent	RecursiveLanguageModelAgent
Action shape	JSON tool call	Python snippet executed in a sandbox
Primary LM context	Full input + tool catalog	`InputsSummary` + tool catalog
Long-input handling	Pass through prompt	External environment via `inputs[field]`
Recursive sub-LM	None	`llm_query` / `llm_query_batched`
Cost lever	Choose one model	Choose a cheap `sub_language_model`
Suited to	Discrete, well-typed actions	Long inputs, sparse / semantic queries

Prefer RecursiveLanguageModelAgent when the input dwarfs the query and the relevant slice cannot be selected in advance: long documents, large logs, large lists where a few items decide the answer.

Common Traps

These are the same pitfalls you would worry about with ordinary recursive functions in a CS101 course: base cases, termination, type mismatches, but applied to an agent. (Recall: a base case is the condition under which a recursive function stops recursing.)

Infinite recursion in disguise. The agent itself never recurses on its own inputs, but a tool body can: for example, a fetch tool whose next URL is computed from the previous sub-LM answer. Without an explicit decreasing measure (recursion depth, byte budget, set of already-visited URLs), such tools loop forever. Treat tool-induced recursion the same way you would treat factorial without a base case: insist on an argument that strictly shrinks.
Unbounded depth. max_iterations bounds primary-LM turns and max_llm_calls bounds sub-LM calls, but neither bounds the depth of nested tool calls inside one snippet. Check that a snippet cannot build arbitrarily deep call chains.
Schema drift. The sub-LM returns plain strings, not structured data. If you aggregate those strings without validating them, a malformed answer slips into the final submit payload and the payload then fails schema validation (validation = checking the output matches the declared DataModel). Always parse and filter sub-LM outputs before aggregating.
Preview retyping. Copying values out of the InputsSummary preview into a sub-LM prompt silently smuggles truncated data past the model. The binding inputs[field] is the only correct read path.
Sandbox syntax errors. The sandbox parses each snippet before running it. An invalid f-string or an unbalanced brace produces a SyntaxError observation, and the LM has to regenerate. Repeated parse failures eat into max_iterations without producing any answer.

Complete example

A real task: incident triage over a long multi-service log. The input pairs a short question (fully visible to the primary LM) with a 2000-line log (only previewed). The question states only the goal; the agent decides how. Answering needs both halves of the design, code to find the first error line deterministically (structure), and the sub-LM to explain it (meaning):

import asyncio
from dotenv import load_dotenv
import synalinks

class LogReport(synalinks.DataModel):
    question: str = synalinks.Field(description="The triage question to answer")
    log: str = synalinks.Field(description="The full application log")

class Incident(synalinks.DataModel):
    first_error_line: str = synalinks.Field(
        description="The first line in the log containing 'ERROR', copied verbatim")
    explanation: str = synalinks.Field(
        description="One-sentence, plain-English explanation of that error")

async def main():
    load_dotenv()
    synalinks.clear_session()

    primary = synalinks.LanguageModel(model="vllm/Qwen/Qwen3.8-27B")
    cheap   = synalinks.LanguageModel(model="vllm/Qwen/Qwen3.8-27B")

    inputs = synalinks.Input(data_model=LogReport)
    outputs = await synalinks.RLM(
        data_model=Incident,
        language_model=primary,
        sub_language_model=cheap,
        max_iterations=5,
        max_llm_calls=8,
    )(inputs)
    agent = synalinks.Program(inputs=inputs, outputs=outputs, name="rlm_triage")

    log = open("app.log").read()
    question = (
        "An incident took place. Find its root cause, the first error in this "
        "chronological log, and explain in one sentence what went wrong."
    )
    result = await agent(LogReport(question=question, log=log))
    print(result.prettify_json())

if __name__ == "__main__":
    asyncio.run(main())

Inside the agent(...) call the primary LM sees only the preview of the log. From the goal alone it works out the approach: scan the full log inside the sandbox, keep the ERROR lines, take the first (the root cause: db here, with api / worker cascading off it), hand that one line to the sub-LM for a human-readable explanation, and submit the structured Incident. The structural part of the answer (first_error_line) is copied verbatim by deterministic code, not guessed, so it is correct regardless of model size, and a cheap sub-LM only ever phrases a single short line.

Expected output (representative)

Log: 2000 lines, 116878 characters
(ground truth: first failure in 'db' at 2026-01-15T10:00:00)

============================================================
Example 1: incident triage via RLM
============================================================

Example 1 result:
  first_error_line: 2026-01-15T10:00:00 ERROR db: connection pool exhausted (max=20): all connections checked out, rejecting new checkouts
  explanation:      The database exhausted its connection pool (all 20 connections were in use), so it rejected new checkouts and dependent services began to fail.
  first ERROR line correct? ✅

============================================================
Example 2: walk the trajectory
============================================================

Trajectory has 4 messages:
  [00] assistant {"code": "errors = [l for l in inputs['log'].splitlines() if ' ERROR '...
  [01] tool      {'stdout': "2026-01-15T10:00:00 ERROR db: connection pool exhausted...
  [02] assistant {"code": "first = errors[0]; s = llm_query(prompt=f'Explain: {first}')...
  [03] tool      {'submit': 'accepted'}

Output is stochastic (varies from run to run) and depends heavily on the models you pick. The first_error_line is deterministic: it is copied from the log by code, not the model, so a model that actually runs the scan gets it exactly right every time; only the phrasing of explanation varies. A capable primary model closes the loop in two or three turns. A small local model (ollama/qwen3:8b) is slower and less reliable here: it can over-think each step or guess from the preview instead of scanning, which is exactly why the deterministic ✅ / ❌ check above is worth printing. The lesson generalizes: keep the structural part of the answer in code so it stays correct independent of model strength, and spend the LM only on what needs language.

Take-Home Summary

Long input as environment. The primary LM sees the summary; the full value is bound in the sandbox as inputs[field].
Two recursive primitives. llm_query and llm_query_batched each return a dict with a result key (and an error key when they short-circuit or when an element fails).
Single shared budget. max_llm_calls bounds both primitives at once. Each agent(...) call gets a fresh counter; concurrent calls do not fight over one budget.
Choice of sub_language_model dominates cost. Use a small, cheap model unless you have measured that you need more.
Working rules. The default instructions= encodes five rules tuned for the long-input, sparse-query regime; override if needed.
Termination. The agent stops when a snippet calls submit(result={...}); the payload is validated against your target DataModel. If max_iterations runs out without a submit, a final inference step formats whatever trajectory has accumulated into the schema. Each individual snippet is bounded by timeout.

      {

        "content": "<instructions>\nYou solve the user task by calling a SINGLE tool,\n`run_python_code(code=...)`, with Python that programmatically\nexplores the inputs and recursively delegates semantic work to a sub-LM. It\nruns your snippet in a persistent sandbox and returns\n`{\"stdout\": ..., \"stderr\": ..., \"error\": ...}`; state persists across calls\n(variables, imports and function definitions stay defined).\n\nIMPORTANT: This is ITERATIVE. Each snippet runs, you read the output, then you\ndecide what to do next. Do NOT try to solve everything in one step.\n\nTreat the inputs as an *external environment*, not as text in your\nprompt. Long documents and large collections live in the sandbox and\nare read with `inputs[field]`. The prompt only shows an\n`InputsSummary` with previews and sizes, never re-type values from\nthe preview.\n\nTwo recursive helpers are always defined in the sandbox:\n\n- `llm_query(prompt)`, query a sub-LM with one prompt; returns\n  `{\"result\": <text>}`. Use it for semantic work on snippets you've\n  already carved out with code (search, classification, summarization,\n  reformatting).

        "content": "<instructions>\nYou solve the user task by calling a SINGLE tool,\n`run_python_code(code=...)`, with Python that programmatically\nexplores the inputs and recursively delegates semantic work to a sub-LM. It\nruns your snippet in a persistent sandbox and returns\n`{\"stdout\": ..., \"stderr\": ..., \"error\": ...}`; state persists across calls\n(variables, imports and function definitions stay defined).\n\nIMPORTANT: This is ITERATIVE. Each snippet runs, you read the output, then you\ndecide what to do next. Do NOT try to solve everything in one step.\n\nTreat the inputs as an *external environment*, not as text in your\nprompt. Long documents and large collections live in the sandbox and\nare read with `inputs[field]`. The prompt only shows an\n`InputsSummary` with previews and sizes, never re-type values from\nthe preview.\n\nTwo recursive helpers are always defined in the sandbox:\n\n- `llm_query(prompt)`, query a sub-LM with one prompt; returns\n  `{\"result\": <text>}`. Use it for semantic work on snippets you've\n  already carved out with code (search, classification, summarization,\n  reformatting). Pass *only the relevant snippet*, the sub-LM has its\n  own context budget.\n- `llm_query_batched(prompts)`, same, but takes a list and runs the\n  prompts concurrently. Returns `{\"result\": [<text-or-error>, ...]}`\n  preserving input order; failed prompts come back as strings prefixed\n  with `[error] <ExceptionType>: <message>`, filter them before\n  aggregating. Strongly preferred over a Python loop of `llm_query`\n  calls, sequential calls waste wall time.\n\nYou have a hard budget of 8 sub-LM calls per run; the\ncounter is shared between `llm_query` and `llm_query_batched`. When\nexhausted, both helpers short-circuit with\n`{\"result\": <empty>, \"error\": \"<msg>\"}` without consuming any quota,\ncheck `error` before trusting `result`. Plan recursion accordingly:\nprefer code-side aggregation (regex, set ops, sorting,\ndict-comprehension counting) over re-querying.\n\nUse `print(...)` to log intermediate observations. Call sandbox tools\ndirectly, e.g. `out = llm_query(prompt)`.\n\nA snippet looks like this (note the variable is `inputs`, plural: it is a\ndict; `input` is something else):\n\n    text = inputs[\"some_field\"]          # read the full value via the binding\n    out = llm_query(prompt=f\"... {text[:500]} ...\")   # returns {\"result\": ...}\n    submit(result={\"answer\": out[\"result\"]})\n\nWorking rules:\n\n1. EXPLORE FIRST. Print sample values, lengths, types, and shapes of\n   `inputs[field]` before slicing or batching. A cheap probe turn\n   prevents wasted sub-LM calls on the wrong field or shape.\n2. CODE FOR STRUCTURE, `llm_query` FOR MEANING. Regex, slicing, and\n   set ops find WHERE things are; the sub-LM understands WHAT they\n   mean. Don't burn `llm_query` budget on aggregation a one-liner can\n   do.\n3. MINIMIZE RETYPING. When values are long, precise, or error-prone\n   (IDs, numbers, quoted text, code), re-access them via\n   `inputs[field]` and compute in Python. Never copy from the\n   `InputsSummary` preview into a sub-LM prompt, the preview is\n   truncated.\n4. VERIFY BEFORE SUBMITTING. If results look wrong (empty, zeros,\n   unexpected shape), inspect them on a separate turn. Don't submit a\n   guess.\n5. `submit` IS TERMINAL. The snippet runs to completion (so a\n   `print(...)` next to `submit(...)` is captured into the\n   observation), but a successful submit ends the loop with no\n   follow-up turn; you never get to read that print. Inspect on one\n   turn, submit on the next.\n\nTermination: call `submit(result={...})` from inside your snippet, with\n`result` matching its schema. `submit`, `llm_query` and `llm_query_batched`\nare plain Python functions already defined *inside* the sandbox; they are\nNOT native tool calls, never emit a tool call for them. Call them directly,\nand only from the code you pass to `run_python_code`. `submit` is the only termination\npath; an empty snippet is a no-op and you'll be reminded to call `submit`.\nDon't run out of iterations without calling it.\n\nCode runs in a real Python 3 interpreter (CPython) with the full standard library and any installed third-party packages. State persists across runs: variables, imports, functions and classes defined in earlier runs remain available, and an error does not reset the namespace. Use `print(...)` to emit results to stdout; the value of the snippet's last expression is also captured (the `result` convention: end with a `result` expression to return it). Any tools bound to the sandbox are exposed as global functions; call them directly, `result = tool_name(...)`. By default the sandbox is confined: `open(...)` / `pathlib` and the file tools (`read_file`, `write_file`, `list_files`, ...) operate on one shared virtual filesystem (use absolute paths like `/work/out.txt`), the host filesystem is hidden, and outbound network is disabled; reach the network only through a bound tool such as `http_fetch` when one is provided.\n</instructions>\n\n<sandbox_functions>\nCall `submit(result={...})` where `result` is a dict with these fields:\n\n- first_error_line (str): The first line in the log containing 'ERROR', copied verbatim\n- explanation (str): One-sentence, plain-English explanation of that error\n</sandbox_functions>\n"

        "reasoning_content": "Interesting — the log is extremely repetitive and looks mostly like normal traffic. There are only 4 ERROR lines, all clustered together between 10:00:00–10:00:09. No WARN lines, no \"leak\" or \"checked out\" lines either, and \"connection established\" is being emitted repeatedly (roughly every 15 seconds). Wait — if there's a pool of max=20 and \"connection established\" is being emitted once every 15 seconds... 1 hour is 3600 seconds = 240 connections established. If connections are being established but never returned to the pool (a connection leak), then the pool would get exhausted after 20 connections. Hmm, 20 connections × 15 seconds = 300 seconds = 5 minutes. But the errors occurred after about 1 hour.\n\nLet me analyze more carefully:\n- Count the number of \"connection established\" lines before 10:00:00.\n- Check for \"connection closed\" / \"returned\" / \"released\" lines.\n- Check whether there's anything abnormal in the first ~1199 lines: a repeating pattern with 3 services rotating? Let me look for unique message templates and check whether there's anything anomalous.\n\nActually, looking at the top: the pattern is auth, api, cache, worker, db (established), then auth, api, cache, worker, db... repeating every 15 seconds. The level rotates through INFO/DEBUG. So \"db: connection established\" appears once every 15 seconds. If each one is a new connection that never gets closed, the pool would hit 20 after 20*15 seconds = 5 minutes. But the errors started at the 60-minute mark. So maybe that's not the cause, or maybe the log is synthetic and just repetitive.\n\nWait, maybe the root-cause event is a specific anomalous line buried in the 1199 lines of normal noise. Let me look for anomalies: lines that don't match the repeating template. I'll enumerate the unique message templates (with numeric values stripped out) and their counts.\n",

        "content": "<instructions>\nYou solve the user task by calling a SINGLE tool,\n`run_python_code(code=...)`, with Python that programmatically\nexplores the inputs and recursively delegates semantic work to a sub-LM. It\nruns your snippet in a persistent sandbox and returns\n`{\"stdout\": ..., \"stderr\": ..., \"error\": ...}`; state persists across calls\n(variables, imports and function definitions stay defined).\n\nIMPORTANT: This is ITERATIVE. Each snippet runs, you read the output, then you\ndecide what to do next. Do NOT try to solve everything in one step.\n\nTreat the inputs as an *external environment*, not as text in your\nprompt. Long documents and large collections live in the sandbox and\nare read with `inputs[field]`. The prompt only shows an\n`InputsSummary` with previews and sizes, never re-type values from\nthe preview.\n\nTwo recursive helpers are always defined in the sandbox:\n\n- `llm_query(prompt)`, query a sub-LM with one prompt; returns\n  `{\"result\": <text>}`. Use it for semantic work on snippets you've\n  already carved out with code (search, classification, summarization,\n  reformatting). Pass *only the relevant snippet*, the sub-LM has its\n  own context budget.\n- `llm_query_batched(prompts)`, same, but takes a list and runs the\n  prompts concurrently. Returns `{\"result\": [<text-or-error>, ...]}`\n  preserving input order; failed prompts come back as strings prefixed\n  with `[error] <ExceptionType>: <message>`, filter them before\n  aggregating. Strongly preferred over a Python loop of `llm_query`\n  calls, sequential calls waste wall time.\n\nYou have a hard budget of 8 sub-LM calls per run; the\ncounter is shared between `llm_query` and `llm_query_batched`. When\nexhausted, both helpers short-circuit with\n`{\"result\": <empty>, \"error\": \"<msg>\"}` without consuming any quota,\ncheck `error` before trusting `result`. Plan recursion accordingly:\nprefer code-side aggregation (regex, set ops, sorting,\ndict-comprehension counting) over re-querying.\n\nUse `print(...)` to log intermediate observations. Call sandbox tools\ndirectly, e.g. `out = llm_query(prompt)`.\n\nA snippet looks like this (note the variable is `inputs`, plural: it is a\ndict; `input` is something else):\n\n    text = inputs[\"some_field\"]          # read the full value via the binding\n    out = llm_query(prompt=f\"... {text[:500]} ...\")   # returns {\"result\": ...}\n    submit(result={\"answer\": out[\"result\"]})\n\nWorking rules:\n\n1. EXPLORE FIRST. Print sample values, lengths, types, and shapes of\n   `inputs[field]` before slicing or batching. A cheap probe turn\n   prevents wasted sub-LM calls on the wrong field or shape.\n2. CODE FOR STRUCTURE, `llm_query` FOR MEANING. Regex, slicing, and\n   set ops find WHERE things are; the sub-LM understands WHAT they\n   mean. Don't burn `llm_query` budget on aggregation a one-liner can\n   do.\n3. MINIMIZE RETYPING. When values are long, precise, or error-prone\n   (IDs, numbers, quoted text, code), re-access them via\n   `inputs[field]` and compute in Python. Never copy from the\n   `InputsSummary` preview into a sub-LM prompt, the preview is\n   truncated.\n4. VERIFY BEFORE SUBMITTING. If results look wrong (empty, zeros,\n   unexpected shape), inspect them on a separate turn. Don't submit a\n   guess.\n5. `submit` IS TERMINAL. The snippet runs to completion (so a\n   `print(...)` next to `submit(...)` is captured into the\n   observation), but a successful submit ends the loop with no\n   follow-up turn; you never get to read that print. Inspect on one\n   turn, submit on the next.\n\nTermination: call `submit(result={...})` from inside your snippet, with\n`result` matching its schema. `submit`, `llm_query` and `llm_query_batched`\nare plain Python functions already defined *inside* the sandbox; they are\nNOT native tool calls, never emit a tool call for them. Call them directly,\nand only from the code you pass to `run_python_code`. `submit` is the only termination\npath; an empty snippet is a no-op and you'll be reminded to call `submit`.\nDon't run out of iterations without calling it.\n\nCode runs in a real Python 3 interpreter (CPython) with the full standard library and any installed third-party packages. State persists across runs: variables, imports, functions and classes defined in earlier runs remain available, and an error does not reset the namespace. Use `print(...)` to emit results to stdout; the value of the snippet's last expression is also captured (the `result` convention: end with a `result` expression to return it). Any tools bound to the sandbox are exposed as global functions; call them directly, `result = tool_name(...)`. By default the sandbox is confined: `open(...)` / `pathlib` and the file tools (`read_file`, `write_file`, `list_files`, ...) operate on one shared virtual filesystem (use absolute paths like `/work/out.txt`), the host filesystem is hidden, and outbound network is disabled; reach the network only through a bound tool such as `http_fetch` when one is provided.\n</instructions>\n\n<sandbox_functions>\nCall `submit(result={...})` where `result` is a dict with these fields:\n\n- first_error_line (str): The first line in the log containing 'ERROR', copied verbatim\n- explanation (str): One-sentence, plain-English explanation of that error\n</sandbox_functions>\n"

        "reasoning_content": "Interesting — the log is extremely repetitive and looks mostly like normal traffic. There are only 4 ERROR lines, all clustered together between 10:00:00–10:00:09. No WARN lines, no \"leak\" or \"checked out\" lines either, and \"connection established\" is being emitted repeatedly (roughly every 15 seconds). Wait — if there's a pool of max=20 and \"connection established\" is being emitted once every 15 seconds... 1 hour is 3600 seconds = 240 connections established. If connections are being established but never returned to the pool (a connection leak), then the pool would get exhausted after 20 connections. Hmm, 20 connections × 15 seconds = 300 seconds = 5 minutes. But the errors occurred after about 1 hour.\n\nLet me analyze more carefully:\n- Count the number of \"connection established\" lines before 10:00:00.\n- Check for \"connection closed\" / \"returned\" / \"released\" lines.\n- Check whether there's anything abnormal in the first ~1199 lines: a repeating pattern with 3 services rotating? Let me look for unique message templates and check whether there's anything anomalous.\n\nActually, looking at the top: the pattern is auth, api, cache, worker, db (established), then auth, api, cache, worker, db... repeating every 15 seconds. The level rotates through INFO/DEBUG. So \"db: connection established\" appears once every 15 seconds. If each one is a new connection that never gets closed, the pool would hit 20 after 20*15 seconds = 5 minutes. But the errors started at the 60-minute mark. So maybe that's not the cause, or maybe the log is synthetic and just repetitive.\n\nWait, maybe the root-cause event is a specific anomalous line buried in the 1199 lines of normal noise. Let me look for anomalies: lines that don't match the repeating template. I'll enumerate the unique message templates (with numeric values stripped out) and their counts.\n",

So the \"root cause\" has to be derived from the ERROR lines themselves and their context.\n\nWait — let me think about the sequence of events. The log shows a \"db: connection established\" every 15 seconds. There's no \"connection released/returned\" event. 400 \"connection established\" lines in 1 hour… with a pool of max=20, if each request opens a new connection and doesn't return it, the pool would get exhausted way before the 1-hour mark. But the errors only appear at 10:00:00.\n\nHmm, maybe the pattern changes after the error? Let me check the lines after 1204 — the tail end shows the normal pattern resuming. So this is a burst: 4 error lines sandwiched between normal traffic.\n\nSo what's the root cause? The first ERROR: \"db: connection pool exhausted (max=20): all connections checked out, rejecting new checkouts\". Then downstream: api query times out waiting for db connection, worker retry can't acquire, api returns 503.\n\nGiven that the log shows \"connection established\" events with no corresponding release events, the classic root cause is: a connection leak — connections checked out of the pool were never returned (leaked), so all 20 connections in the pool got consumed, exhausting it, and new requests failed → timeouts → 503.\n\nActually, wait. Let me reconsider: could it be \"connection established\" 400 times in 1 hour, with the pool maxing at 20? If connections are properly reused from the pool, \"connection established\" should only appear at pool fill time. If a new physical connection is established every 15 seconds, each request is opening a new connection and not returning the old one — a leak.\n\nBut hold on — is it possible that the true root cause is stated in a line I've overlooked? Let me re-check for any line that doesn't match the template — all 2000 lines matched the template. So there's no hidden single anomalous line. The incident is just a 4-line burst.\n\nLet me verify the timestamps around the error and confirm chronology: the error is at 10:00:00, and normal traffic resumes at 10:00:12. Also, let me check whether there's a \"connection established\" right before the exhaustion (10:00:00 is 60 minutes after 09:00:00). Number of established connections before 10:00:00 = 400 lines at 15-second intervals = 400 × 15 sec = 6000 sec = 100 minutes. Hmm, but the log is only 1 hour: 09:00:00 → 10:39:57 is 100 minutes! 2000 lines × 3 seconds = 6000 seconds = 100 minutes. So the log spans 09:00:00 to 10:39:57.\n\nBefore the error (10:00:00): 60 minutes = 3600 seconds = 240 intervals → about 241 db lines? But in the template count, \"connection established\" lines total 400 (INFO 343 + DEBUG 57). Over the full 100 minutes, 400 × 15 seconds = exactly 6000 seconds. OK.\n\nSo before the error, 240 connections were established in 1 hour, with no release lines. If each request leaks one connection… the pool of 20 should be exhausted after 5 minutes. That contradicts the error appearing at 60 minutes.\n\nUnless — the leak only starts later? But all lines are uniform normal lines. Hmm.\n\nMaybe the intended interpretation is simpler: this is a synthetic log, and the root cause is the first ERROR itself: the db connection pool (max=20) was exhausted — all connections were checked out — which caused API timeouts, worker failures, and 503s. The \"root cause\" answer is: the database connection pool hit its max=20 limit (connections weren't being released), exhausting the pool, cascading to API timeouts and 503 errors.\n\nThe question asks: \"Find its root cause, i.e., the first error in this chronological log, and explain in one sentence what went wrong.\"\n\nSo the expected output is:\n- first_error_line: \"2026-01-15T10:00:00 ERROR db: connection pool exhausted (max=20): all connections checked out, rejecting new checkouts\"\n- explanation: e.g., \"The database connection pool (max=20) was exhausted because all connections were checked out and not returned, so new requests could not acquire a connection and failed with timeouts and 503s.\"\n\nShould I verify the first ERROR line is really line 1200, and also check for the lowercase \"error\" substring or other error indicators like \"FATAL\"? Let me quickly check. Also verify the chronology: is the log strictly in chronological order?\n\nI could use llm_query to double-check the semantic root-cause reasoning against the relevant snippet (the 4 error lines + context). That's 1 of 8 budget calls. I think the analysis is pretty clear even without it, but a semantic check might help craft a good one-sentence explanation. Actually, the semantics are simple enough, so I can do it myself. But the guidelines say to use the sub-LM for semantic work. A single call to confirm the root cause is reasonable, but honestly the data is unambiguous: the first error is the db pool exhaustion, and the subsequent errors reference it (\"waiting for a db connection\", \"could not acquire a db connection\", \"database unavailable\").\n\nLet me do a final verification pass: check whether the log is chronological, check for any line containing \"error\" (case-insensitive) before line 1200, confirm the exact first ERROR line string, and then submit.\n",

        "reasoning_content": "Interesting — the log is extremely repetitive and looks mostly like normal traffic. There are only 4 ERROR lines, all clustered together between 10:00:00–10:00:09. No WARN lines, no \"leak\" or \"checked out\" lines either, and \"connection established\" is being emitted repeatedly (roughly every 15 seconds). Wait — if there's a pool of max=20 and \"connection established\" is being emitted once every 15 seconds... 1 hour is 3600 seconds = 240 connections established. If connections are being established but never returned to the pool (a connection leak), then the pool would get exhausted after 20 connections. Hmm, 20 connections × 15 seconds = 300 seconds = 5 minutes. But the errors occurred after about 1 hour.\n\nLet me analyze more carefully:\n- Count the number of \"connection established\" lines before 10:00:00.\n- Check for \"connection closed\" / \"returned\" / \"released\" lines.\n- Check whether there's anything abnormal in the first ~1199 lines: a repeating pattern with 3 services rotating? Let me look for unique message templates and check whether there's anything anomalous.\n\nActually, looking at the top: the pattern is auth, api, cache, worker, db (established), then auth, api, cache, worker, db... repeating every 15 seconds. The level rotates through INFO/DEBUG. So \"db: connection established\" appears once every 15 seconds. If each one is a new connection that never gets closed, the pool would hit 20 after 20*15 seconds = 5 minutes. But the errors started at the 60-minute mark. So maybe that's not the cause, or maybe the log is synthetic and just repetitive.\n\nWait, maybe the root-cause event is a specific anomalous line buried in the 1199 lines of normal noise. Let me look for anomalies: lines that don't match the repeating template. I'll enumerate the unique message templates (with numeric values stripped out) and their counts.\n",

        "reasoning_content": "In other words, all 1199 lines before the error are normal repeating traffic. There's no anomaly line before the error. So the \"root cause\" has to be derived from the ERROR lines themselves and their context.\n\nWait — let me think about the sequence of events. The log shows a \"db: connection established\" every 15 seconds. There's no \"connection released/returned\" event. 400 \"connection established\" lines in 1 hour… with a pool of max=20, if each request opens a new connection and doesn't return it, the pool would get exhausted way before the 1-hour mark. But the errors only appear at 10:00:00.\n\nHmm, maybe the pattern changes after the error? Let me check the lines after 1204 — the tail end shows the normal pattern resuming. So this is a burst: 4 error lines sandwiched between normal traffic.\n\nSo what's the root cause? The first ERROR: \"db: connection pool exhausted (max=20): all connections checked out, rejecting new checkouts\". Then downstream: api query times out waiting for db connection, worker retry can't acquire, api returns 503.\n\nGiven that the log shows \"connection established\" events with no corresponding release events, the classic root cause is: a connection leak — connections checked out of the pool were never returned (leaked), so all 20 connections in the pool got consumed, exhausting it, and new requests failed → timeouts → 503.\n\nActually, wait. Let me reconsider: could it be \"connection established\" 400 times in 1 hour, with the pool maxing at 20? If connections are properly reused from the pool, \"connection established\" should only appear at pool fill time. If a new physical connection is established every 15 seconds, each request is opening a new connection and not returning the old one — a leak.\n\nBut hold on — is it possible that the true root cause is stated in a line I've overlooked? Let me re-check for any line that doesn't match the template — all 2000 lines matched the template. So there's no hidden single anomalous line. The incident is just a 4-line burst.\n\nLet me verify the timestamps around the error and confirm chronology: the error is at 10:00:00, and normal traffic resumes at 10:00:12. Also, let me check whether there's a \"connection established\" right before the exhaustion (10:00:00 is 60 minutes after 09:00:00). Number of established connections before 10:00:00 = 400 lines at 15-second intervals = 400 × 15 sec = 6000 sec = 100 minutes. Hmm, but the log is only 1 hour: 09:00:00 → 10:39:57 is 100 minutes! 2000 lines × 3 seconds = 6000 seconds = 100 minutes. So the log spans 09:00:00 to 10:39:57.\n\nBefore the error (10:00:00): 60 minutes = 3600 seconds = 240 intervals → about 241 db lines? But in the template count, \"connection established\" lines total 400 (INFO 343 + DEBUG 57). Over the full 100 minutes, 400 × 15 seconds = exactly 6000 seconds. OK.\n\nSo before the error, 240 connections were established in 1 hour, with no release lines. If each request leaks one connection… the pool of 20 should be exhausted after 5 minutes. That contradicts the error appearing at 60 minutes.\n\nUnless — the leak only starts later? But all lines are uniform normal lines. Hmm.\n\nMaybe the intended interpretation is simpler: this is a synthetic log, and the root cause is the first ERROR itself: the db connection pool (max=20) was exhausted — all connections were checked out — which caused API timeouts, worker failures, and 503s. The \"root cause\" answer is: the database connection pool hit its max=20 limit (connections weren't being released), exhausting the pool, cascading to API timeouts and 503 errors.\n\nThe question asks: \"Find its root cause, i.e., the first error in this chronological log, and explain in one sentence what went wrong.\"\n\nSo the expected output is:\n- first_error_line: \"2026-01-15T10:00:00 ERROR db: connection pool exhausted (max=20): all connections checked out, rejecting new checkouts\"\n- explanation: e.g., \"The database connection pool (max=20) was exhausted because all connections were checked out and not returned, so new requests could not acquire a connection and failed with timeouts and 503s.\"\n\nShould I verify the first ERROR line is really line 1200, and also check for the lowercase \"error\" substring or other error indicators like \"FATAL\"? Let me quickly check. Also verify the chronology: is the log strictly in chronological order?\n\nI could use llm_query to double-check the semantic root-cause reasoning against the relevant snippet (the 4 error lines + context). That's 1 of 8 budget calls. I think the analysis is pretty clear even without it, but a semantic check might help craft a good one-sentence explanation. Actually, the semantics are simple enough, so I can do it myself. But the guidelines say to use the sub-LM for semantic work. A single call to confirm the root cause is reasonable, but honestly the data is unambiguous: the first error is the db pool exhaustion, and the subsequent errors reference it (\"waiting for a db connection\", \"could not acquire a db connection\", \"database unavailable\").\n\nLet me do a final verification pass: check whether the log is chronological, check for any line containing \"error\" (case-insensitive) before line 1200, confirm the exact first ERROR line string, and then submit.\n",

        "content": "<instructions>\nYou solve the user task by calling a SINGLE tool,\n`run_python_code(code=...)`, with Python that programmatically\nexplores the inputs and recursively delegates semantic work to a sub-LM. It\nruns your snippet in a persistent sandbox and returns\n`{\"stdout\": ..., \"stderr\": ..., \"error\": ...}`; state persists across calls\n(variables, imports and function definitions stay defined).\n\nIMPORTANT: This is ITERATIVE. Each snippet runs, you read the output, then you\ndecide what to do next. Do NOT try to solve everything in one step.\n\nTreat the inputs as an *external environment*, not as text in your\nprompt. Long documents and large collections live in the sandbox and\nare read with `inputs[field]`. The prompt only shows an\n`InputsSummary` with previews and sizes, never re-type values from\nthe preview.\n\nTwo recursive helpers are always defined in the sandbox:\n\n- `llm_query(prompt)`, query a sub-LM with one prompt; returns\n  `{\"result\": <text>}`. Use it for semantic work on snippets you've\n  already carved out with code (search, classification, summarization,\n  reformatting). Pass *only the relevant snippet*, the sub-LM has its\n  own context budget.\n- `llm_query_batched(prompts)`, same, but takes a list and runs the\n  prompts concurrently. Returns `{\"result\": [<text-or-error>, ...]}`\n  preserving input order; failed prompts come back as strings prefixed\n  with `[error] <ExceptionType>: <message>`, filter them before\n  aggregating. Strongly preferred over a Python loop of `llm_query`\n  calls, sequential calls waste wall time.\n\nYou have a hard budget of 8 sub-LM calls per run; the\ncounter is shared between `llm_query` and `llm_query_batched`. When\nexhausted, both helpers short-circuit with\n`{\"result\": <empty>, \"error\": \"<msg>\"}` without consuming any quota,\ncheck `error` before trusting `result`. Plan recursion accordingly:\nprefer code-side aggregation (regex, set ops, sorting,\ndict-comprehension counting) over re-querying.\n\nUse `print(...)` to log intermediate observations. Call sandbox tools\ndirectly, e.g. `out = llm_query(prompt)`.\n\nA snippet looks like this (note the variable is `inputs`, plural: it is a\ndict; `input` is something else):\n\n    text = inputs[\"some_field\"]          # read the full value via the binding\n    out = llm_query(prompt=f\"... {text[:500]} ...\")   # returns {\"result\": ...}\n    submit(result={\"answer\": out[\"result\"]})\n\nWorking rules:\n\n1. EXPLORE FIRST. Print sample values, lengths, types, and shapes of\n   `inputs[field]` before slicing or batching. A cheap probe turn\n   prevents wasted sub-LM calls on the wrong field or shape.\n2. CODE FOR STRUCTURE, `llm_query` FOR MEANING. Regex, slicing, and\n   set ops find WHERE things are; the sub-LM understands WHAT they\n   mean. Don't burn `llm_query` budget on aggregation a one-liner can\n   do.\n3. MINIMIZE RETYPING. When values are long, precise, or error-prone\n   (IDs, numbers, quoted text, code), re-access them via\n   `inputs[field]` and compute in Python. Never copy from the\n   `InputsSummary` preview into a sub-LM prompt, the preview is\n   truncated.\n4. VERIFY BEFORE SUBMITTING. If results look wrong (empty, zeros,\n   unexpected shape), inspect them on a separate turn. Don't submit a\n   guess.\n5. `submit` IS TERMINAL. The snippet runs to completion (so a\n   `print(...)` next to `submit(...)` is captured into the\n   observation), but a successful submit ends the loop with no\n   follow-up turn; you never get to read that print. Inspect on one\n   turn, submit on the next.\n\nTermination: call `submit(result={...})` from inside your snippet, with\n`result` matching its schema. `submit`, `llm_query` and `llm_query_batched`\nare plain Python functions already defined *inside* the sandbox; they are\nNOT native tool calls, never emit a tool call for them. Call them directly,\nand only from the code you pass to `run_python_code`. `submit` is the only termination\npath; an empty snippet is a no-op and you'll be reminded to call `submit`.\nDon't run out of iterations without calling it.\n\nCode runs in a real Python 3 interpreter (CPython) with the full standard library and any installed third-party packages. State persists across runs: variables, imports, functions and classes defined in earlier runs remain available, and an error does not reset the namespace. Use `print(...)` to emit results to stdout; the value of the snippet's last expression is also captured (the `result` convention: end with a `result` expression to return it). Any tools bound to the sandbox are exposed as global functions; call them directly, `result = tool_name(...)`. By default the sandbox is confined: `open(...)` / `pathlib` and the file tools (`read_file`, `write_file`, `list_files`, ...) operate on one shared virtual filesystem (use absolute paths like `/work/out.txt`), the host filesystem is hidden, and outbound network is disabled; reach the network only through a bound tool such as `http_fetch` when one is provided.\n</instructions>\n\n<sandbox_functions>\nCall `submit(result={...})` where `result` is a dict with these fields:\n\n- first_error_line (str): The first line in the log containing 'ERROR', copied verbatim\n- explanation (str): One-sentence, plain-English explanation of that error\n</sandbox_functions>\n"

No WARN lines, no \"leak\" or \"checked out\" lines either, and \"connection established\" is being emitted repeatedly (roughly every 15 seconds). Wait — if there's a pool of max=20 and \"connection established\" is being emitted once every 15 seconds... 1 hour is 3600 seconds = 240 connections established. If connections are being established but never returned to the pool (a connection leak), then the pool would get exhausted after 20 connections. Hmm, 20 connections × 15 seconds = 300 seconds = 5 minutes. But the errors occurred after about 1 hour.\n\nLet me analyze more carefully:\n- Count the number of \"connection established\" lines before 10:00:00.\n- Check for \"connection closed\" / \"returned\" / \"released\" lines.\n- Check whether there's anything abnormal in the first ~1199 lines: a repeating pattern with 3 services rotating? Let me look for unique message templates and check whether there's anything anomalous.\n\nActually, looking at the top: the pattern is auth, api, cache, worker, db (established), then auth, api, cache, worker, db... repeating every 15 seconds. The level rotates through INFO/DEBUG. So \"db: connection established\" appears once every 15 seconds. If each one is a new connection that never gets closed, the pool would hit 20 after 20*15 seconds = 5 minutes. But the errors started at the 60-minute mark. So maybe that's not the cause, or maybe the log is synthetic and just repetitive.\n\nWait, maybe the root-cause event is a specific anomalous line buried in the 1199 lines of normal noise. Let me look for anomalies: lines that don't match the repeating template. I'll enumerate the unique message templates (with numeric values stripped out) and their counts.\n",

        "reasoning_content": "In other words, all 1199 lines before the error are normal repeating traffic. There's no anomaly line before the error. So the \"root cause\" has to be derived from the ERROR lines themselves and their context.\n\nWait — let me think about the sequence of events. The log shows a \"db: connection established\" every 15 seconds. There's no \"connection released/returned\" event. 400 \"connection established\" lines in 1 hour… with a pool of max=20, if each request opens a new connection and doesn't return it, the pool would get exhausted way before the 1-hour mark. But the errors only appear at 10:00:00.\n\nHmm, maybe the pattern changes after the error? Let me check the lines after 1204 — the tail end shows the normal pattern resuming. So this is a burst: 4 error lines sandwiched between normal traffic.\n\nSo what's the root cause? The first ERROR: \"db: connection pool exhausted (max=20): all connections checked out, rejecting new checkouts\". Then downstream: api query times out waiting for db connection, worker retry can't acquire, api returns 503.\n\nGiven that the log shows \"connection established\" events with no corresponding release events, the classic root cause is: a connection leak — connections checked out of the pool were never returned (leaked), so all 20 connections in the pool got consumed, exhausting it, and new requests failed → timeouts → 503.\n\nActually, wait. Let me reconsider: could it be \"connection established\" 400 times in 1 hour, with the pool maxing at 20? If connections are properly reused from the pool, \"connection established\" should only appear at pool fill time. If a new physical connection is established every 15 seconds, each request is opening a new connection and not returning the old one — a leak.\n\nBut hold on — is it possible that the true root cause is stated in a line I've overlooked? Let me re-check for any line that doesn't match the template — all 2000 lines matched the template. So there's no hidden single anomalous line. The incident is just a 4-line burst.\n\nLet me verify the timestamps around the error and confirm chronology: the error is at 10:00:00, and normal traffic resumes at 10:00:12. Also, let me check whether there's a \"connection established\" right before the exhaustion (10:00:00 is 60 minutes after 09:00:00). Number of established connections before 10:00:00 = 400 lines at 15-second intervals = 400 × 15 sec = 6000 sec = 100 minutes. Hmm, but the log is only 1 hour: 09:00:00 → 10:39:57 is 100 minutes! 2000 lines × 3 seconds = 6000 seconds = 100 minutes. So the log spans 09:00:00 to 10:39:57.\n\nBefore the error (10:00:00): 60 minutes = 3600 seconds = 240 intervals → about 241 db lines? But in the template count, \"connection established\" lines total 400 (INFO 343 + DEBUG 57). Over the full 100 minutes, 400 × 15 seconds = exactly 6000 seconds. OK.\n\nSo before the error, 240 connections were established in 1 hour, with no release lines. If each request leaks one connection… the pool of 20 should be exhausted after 5 minutes. That contradicts the error appearing at 60 minutes.\n\nUnless — the leak only starts later? But all lines are uniform normal lines. Hmm.\n\nMaybe the intended interpretation is simpler: this is a synthetic log, and the root cause is the first ERROR itself: the db connection pool (max=20) was exhausted — all connections were checked out — which caused API timeouts, worker failures, and 503s. The \"root cause\" answer is: the database connection pool hit its max=20 limit (connections weren't being released), exhausting the pool, cascading to API timeouts and 503 errors.\n\nThe question asks: \"Find its root cause, i.e., the first error in this chronological log, and explain in one sentence what went wrong.\"\n\nSo the expected output is:\n- first_error_line: \"2026-01-15T10:00:00 ERROR db: connection pool exhausted (max=20): all connections checked out, rejecting new checkouts\"\n- explanation: e.g., \"The database connection pool (max=20) was exhausted because all connections were checked out and not returned, so new requests could not acquire a connection and failed with timeouts and 503s.\"\n\nShould I verify the first ERROR line is really line 1200, and also check for the lowercase \"error\" substring or other error indicators like \"FATAL\"? Let me quickly check. Also verify the chronology: is the log strictly in chronological order?\n\nI could use llm_query to double-check the semantic root-cause reasoning against the relevant snippet (the 4 error lines + context). That's 1 of 8 budget calls. I think the analysis is pretty clear even without it, but a semantic check might help craft a good one-sentence explanation. Actually, the semantics are simple enough, so I can do it myself. But the guidelines say to use the sub-LM for semantic work. A single call to confirm the root cause is reasonable, but honestly the data is unambiguous: the first error is the db pool exhaustion, and the subsequent errors reference it (\"waiting for a db connection\", \"could not acquire a db connection\", \"database unavailable\").\n\nLet me do a final verification pass: check whether the log is chronological, check for any line containing \"error\" (case-insensitive) before line 1200, confirm the exact first ERROR line string, and then submit.\n",
        "content": "All the lines are uniform boilerplate except for a 4-line ERROR burst at 10:00:00, and the first ERROR (db pool exhaustion) is clearly causing the rest (they all cite failure to acquire a db connection).

        "reasoning_content": "Interesting — the log is extremely repetitive and looks mostly like normal traffic. There are only 4 ERROR lines, all clustered together between 10:00:00–10:00:09. No WARN lines, no \"leak\" or \"checked out\" lines either, and \"connection established\" is being emitted repeatedly (roughly every 15 seconds). Wait — if there's a pool of max=20 and \"connection established\" is being emitted once every 15 seconds... 1 hour is 3600 seconds = 240 connections established. If connections are being established but never returned to the pool (a connection leak), then the pool would get exhausted after 20 connections. Hmm, 20 connections × 15 seconds = 300 seconds = 5 minutes. But the errors occurred after about 1 hour.\n\nLet me analyze more carefully:\n- Count the number of \"connection established\" lines before 10:00:00.\n- Check for \"connection closed\" / \"returned\" / \"released\" lines.\n- Check whether there's anything abnormal in the first ~1199 lines: a repeating pattern with 3 services rotating? Let me look for unique message templates and check whether there's anything anomalous.\n\nActually, looking at the top: the pattern is auth, api, cache, worker, db (established), then auth, api, cache, worker, db... repeating every 15 seconds. The level rotates through INFO/DEBUG. So \"db: connection established\" appears once every 15 seconds. If each one is a new connection that never gets closed, the pool would hit 20 after 20*15 seconds = 5 minutes. But the errors started at the 60-minute mark. So maybe that's not the cause, or maybe the log is synthetic and just repetitive.\n\nWait, maybe the root-cause event is a specific anomalous line buried in the 1199 lines of normal noise. Let me look for anomalies: lines that don't match the repeating template. I'll enumerate the unique message templates (with numeric values stripped out) and their counts.\n",

        "reasoning_content": "In other words, all 1199 lines before the error are normal repeating traffic. There's no anomaly line before the error. So the \"root cause\" has to be derived from the ERROR lines themselves and their context.\n\nWait — let me think about the sequence of events. The log shows a \"db: connection established\" every 15 seconds. There's no \"connection released/returned\" event. 400 \"connection established\" lines in 1 hour… with a pool of max=20, if each request opens a new connection and doesn't return it, the pool would get exhausted way before the 1-hour mark. But the errors only appear at 10:00:00.\n\nHmm, maybe the pattern changes after the error? Let me check the lines after 1204 — the tail end shows the normal pattern resuming. So this is a burst: 4 error lines sandwiched between normal traffic.\n\nSo what's the root cause? The first ERROR: \"db: connection pool exhausted (max=20): all connections checked out, rejecting new checkouts\". Then downstream: api query times out waiting for db connection, worker retry can't acquire, api returns 503.\n\nGiven that the log shows \"connection established\" events with no corresponding release events, the classic root cause is: a connection leak — connections checked out of the pool were never returned (leaked), so all 20 connections in the pool got consumed, exhausting it, and new requests failed → timeouts → 503.\n\nActually, wait. Let me reconsider: could it be \"connection established\" 400 times in 1 hour, with the pool maxing at 20? If connections are properly reused from the pool, \"connection established\" should only appear at pool fill time. If a new physical connection is established every 15 seconds, each request is opening a new connection and not returning the old one — a leak.\n\nBut hold on — is it possible that the true root cause is stated in a line I've overlooked? Let me re-check for any line that doesn't match the template — all 2000 lines matched the template. So there's no hidden single anomalous line. The incident is just a 4-line burst.\n\nLet me verify the timestamps around the error and confirm chronology: the error is at 10:00:00, and normal traffic resumes at 10:00:12. Also, let me check whether there's a \"connection established\" right before the exhaustion (10:00:00 is 60 minutes after 09:00:00). Number of established connections before 10:00:00 = 400 lines at 15-second intervals = 400 × 15 sec = 6000 sec = 100 minutes. Hmm, but the log is only 1 hour: 09:00:00 → 10:39:57 is 100 minutes! 2000 lines × 3 seconds = 6000 seconds = 100 minutes. So the log spans 09:00:00 to 10:39:57.\n\nBefore the error (10:00:00): 60 minutes = 3600 seconds = 240 intervals → about 241 db lines? But in the template count, \"connection established\" lines total 400 (INFO 343 + DEBUG 57). Over the full 100 minutes, 400 × 15 seconds = exactly 6000 seconds. OK.\n\nSo before the error, 240 connections were established in 1 hour, with no release lines. If each request leaks one connection… the pool of 20 should be exhausted after 5 minutes. That contradicts the error appearing at 60 minutes.\n\nUnless — the leak only starts later? But all lines are uniform normal lines. Hmm.\n\nMaybe the intended interpretation is simpler: this is a synthetic log, and the root cause is the first ERROR itself: the db connection pool (max=20) was exhausted — all connections were checked out — which caused API timeouts, worker failures, and 503s. The \"root cause\" answer is: the database connection pool hit its max=20 limit (connections weren't being released), exhausting the pool, cascading to API timeouts and 503 errors.\n\nThe question asks: \"Find its root cause, i.e., the first error in this chronological log, and explain in one sentence what went wrong.\"\n\nSo the expected output is:\n- first_error_line: \"2026-01-15T10:00:00 ERROR db: connection pool exhausted (max=20): all connections checked out, rejecting new checkouts\"\n- explanation: e.g., \"The database connection pool (max=20) was exhausted because all connections were checked out and not returned, so new requests could not acquire a connection and failed with timeouts and 503s.\"\n\nShould I verify the first ERROR line is really line 1200, and also check for the lowercase \"error\" substring or other error indicators like \"FATAL\"? Let me quickly check. Also verify the chronology: is the log strictly in chronological order?\n\nI could use llm_query to double-check the semantic root-cause reasoning against the relevant snippet (the 4 error lines + context). That's 1 of 8 budget calls. I think the analysis is pretty clear even without it, but a semantic check might help craft a good one-sentence explanation. Actually, the semantics are simple enough, so I can do it myself. But the guidelines say to use the sub-LM for semantic work. A single call to confirm the root cause is reasonable, but honestly the data is unambiguous: the first error is the db pool exhaustion, and the subsequent errors reference it (\"waiting for a db connection\", \"could not acquire a db connection\", \"database unavailable\").\n\nLet me do a final verification pass: check whether the log is chronological, check for any line containing \"error\" (case-insensitive) before line 1200, confirm the exact first ERROR line string, and then submit.\n",
        "content": "All the lines are uniform boilerplate except for a 4-line ERROR burst at 10:00:00, and the first ERROR (db pool exhaustion) is clearly causing the rest (they all cite failure to acquire a db connection).

        "reasoning_content": "Interesting — the log is extremely repetitive and looks mostly like normal traffic. There are only 4 ERROR lines, all clustered together between 10:00:00–10:00:09. No WARN lines, no \"leak\" or \"checked out\" lines either, and \"connection established\" is being emitted repeatedly (roughly every 15 seconds). Wait — if there's a pool of max=20 and \"connection established\" is being emitted once every 15 seconds... 1 hour is 3600 seconds = 240 connections established. If connections are being established but never returned to the pool (a connection leak), then the pool would get exhausted after 20 connections. Hmm, 20 connections × 15 seconds = 300 seconds = 5 minutes. But the errors occurred after about 1 hour.\n\nLet me analyze more carefully:\n- Count the number of \"connection established\" lines before 10:00:00.\n- Check for \"connection closed\" / \"returned\" / \"released\" lines.\n- Check whether there's anything abnormal in the first ~1199 lines: a repeating pattern with 3 services rotating? Let me look for unique message templates and check whether there's anything anomalous.\n\nActually, looking at the top: the pattern is auth, api, cache, worker, db (established), then auth, api, cache, worker, db... repeating every 15 seconds. The level rotates through INFO/DEBUG. So \"db: connection established\" appears once every 15 seconds. If each one is a new connection that never gets closed, the pool would hit 20 after 20*15 seconds = 5 minutes. But the errors started at the 60-minute mark. So maybe that's not the cause, or maybe the log is synthetic and just repetitive.\n\nWait, maybe the root-cause event is a specific anomalous line buried in the 1199 lines of normal noise. Let me look for anomalies: lines that don't match the repeating template. I'll enumerate the unique message templates (with numeric values stripped out) and their counts.\n",

        "reasoning_content": "In other words, all 1199 lines before the error are normal repeating traffic. There's no anomaly line before the error. So the \"root cause\" has to be derived from the ERROR lines themselves and their context.\n\nWait — let me think about the sequence of events. The log shows a \"db: connection established\" every 15 seconds. There's no \"connection released/returned\" event. 400 \"connection established\" lines in 1 hour… with a pool of max=20, if each request opens a new connection and doesn't return it, the pool would get exhausted way before the 1-hour mark. But the errors only appear at 10:00:00.\n\nHmm, maybe the pattern changes after the error? Let me check the lines after 1204 — the tail end shows the normal pattern resuming. So this is a burst: 4 error lines sandwiched between normal traffic.\n\nSo what's the root cause? The first ERROR: \"db: connection pool exhausted (max=20): all connections checked out, rejecting new checkouts\". Then downstream: api query times out waiting for db connection, worker retry can't acquire, api returns 503.\n\nGiven that the log shows \"connection established\" events with no corresponding release events, the classic root cause is: a connection leak — connections checked out of the pool were never returned (leaked), so all 20 connections in the pool got consumed, exhausting it, and new requests failed → timeouts → 503.\n\nActually, wait. Let me reconsider: could it be \"connection established\" 400 times in 1 hour, with the pool maxing at 20? If connections are properly reused from the pool, \"connection established\" should only appear at pool fill time. If a new physical connection is established every 15 seconds, each request is opening a new connection and not returning the old one — a leak.\n\nBut hold on — is it possible that the true root cause is stated in a line I've overlooked? Let me re-check for any line that doesn't match the template — all 2000 lines matched the template. So there's no hidden single anomalous line. The incident is just a 4-line burst.\n\nLet me verify the timestamps around the error and confirm chronology: the error is at 10:00:00, and normal traffic resumes at 10:00:12. Also, let me check whether there's a \"connection established\" right before the exhaustion (10:00:00 is 60 minutes after 09:00:00). Number of established connections before 10:00:00 = 400 lines at 15-second intervals = 400 × 15 sec = 6000 sec = 100 minutes. Hmm, but the log is only 1 hour: 09:00:00 → 10:39:57 is 100 minutes! 2000 lines × 3 seconds = 6000 seconds = 100 minutes. So the log spans 09:00:00 to 10:39:57.\n\nBefore the error (10:00:00): 60 minutes = 3600 seconds = 240 intervals → about 241 db lines? But in the template count, \"connection established\" lines total 400 (INFO 343 + DEBUG 57). Over the full 100 minutes, 400 × 15 seconds = exactly 6000 seconds. OK.\n\nSo before the error, 240 connections were established in 1 hour, with no release lines. If each request leaks one connection… the pool of 20 should be exhausted after 5 minutes. That contradicts the error appearing at 60 minutes.\n\nUnless — the leak only starts later? But all lines are uniform normal lines. Hmm.\n\nMaybe the intended interpretation is simpler: this is a synthetic log, and the root cause is the first ERROR itself: the db connection pool (max=20) was exhausted — all connections were checked out — which caused API timeouts, worker failures, and 503s. The \"root cause\" answer is: the database connection pool hit its max=20 limit (connections weren't being released), exhausting the pool, cascading to API timeouts and 503 errors.\n\nThe question asks: \"Find its root cause, i.e., the first error in this chronological log, and explain in one sentence what went wrong.\"\n\nSo the expected output is:\n- first_error_line: \"2026-01-15T10:00:00 ERROR db: connection pool exhausted (max=20): all connections checked out, rejecting new checkouts\"\n- explanation: e.g., \"The database connection pool (max=20) was exhausted because all connections were checked out and not returned, so new requests could not acquire a connection and failed with timeouts and 503s.\"\n\nShould I verify the first ERROR line is really line 1200, and also check for the lowercase \"error\" substring or other error indicators like \"FATAL\"? Let me quickly check. Also verify the chronology: is the log strictly in chronological order?\n\nI could use llm_query to double-check the semantic root-cause reasoning against the relevant snippet (the 4 error lines + context). That's 1 of 8 budget calls. I think the analysis is pretty clear even without it, but a semantic check might help craft a good one-sentence explanation. Actually, the semantics are simple enough, so I can do it myself. But the guidelines say to use the sub-LM for semantic work. A single call to confirm the root cause is reasonable, but honestly the data is unambiguous: the first error is the db pool exhaustion, and the subsequent errors reference it (\"waiting for a db connection\", \"could not acquire a db connection\", \"database unavailable\").\n\nLet me do a final verification pass: check whether the log is chronological, check for any line containing \"error\" (case-insensitive) before line 1200, confirm the exact first ERROR line string, and then submit.\n",
