Autoresearch

Metric-gated experimental research on a codebase for a fixed duration. Subagents propose and run experiments. The metric decides what survives. The clock decides when to stop. You decide neither.

Role and Iron Laws

You are the orchestrator: manage the clock, dispatch subagents, verify results, gate outcomes, keep the ledger. All experimental work — designing changes, editing code, running training/benchmarks — happens inside subagents.

1. THE CLOCK DECIDES WHEN TO STOP. NOT YOU.
2. THE METRIC DECIDES WHAT SURVIVES. NOT YOU.
3. ONE EXPERIMENT IN FLIGHT AT A TIME. NEVER PARALLEL.
4. EVERY FACT YOU NEED LIVES IN THE LEDGER FILES, NOT IN YOUR HEAD.

Law 3 deliberately deviates from the parallel-subagent pattern of sibling skills: experiments mutate shared state (one working tree, one branch, one compute resource). Parallel dispatch corrupts the protocol. Dispatch each subagent blocking (foreground) and wait for its result.

Law 4 is what lets a run survive 100+ experiments: your context will be compacted or reset overnight. See Resume.

Degrees of freedom are split on purpose:

• Hypothesis selection is free. Subagents choose what to try; you and they may be ambitious, radical, creative — anything inside the focus and scope.
• The protocol is fixed. Verify, gate, and log exactly as written below. No judgment calls except the simplicity criterion.

No subagent tool in this harness? Run the dispatch template yourself, one experiment per iteration, and still run Verify and Gate as a separate step afterwards — never trust the number you just produced without re-extracting it. Re-read the ledger TSV before every hypothesis instead of remembering it.

Inputs

The extraction command must print one number and nothing else; write it so it reads a log path (<log>), not a fixed filename.

Research focus — a free-form directive from the user's prompt: a component, an idea family, a constraint, or a hunch. It bounds hypothesis selection in every dispatch; it never changes the gate. Record it verbatim in the ledger.

Native mode — if the target repo contains a karpathy-style program.md, read it first and adopt its mechanics (metric, commands, scopes, budgets) verbatim. Two things always follow this skill instead: logs and the ledger live in /tmp (see Setup), and the orchestrator gates, not the subagent. A user-stated focus overrides its open-ended charter for choosing hypotheses.

Metric integrity — the code that computes and prints the metric must sit in the frozen scope. If the user's scopes leave it mutable, flag it and get the scopes corrected before starting: experiments that can touch the metric computation produce incomparable numbers. The same applies to the eval data: if the mutable scope can choose or filter what the metric is computed on, that selection is frozen too.

Oracle, not claim — a subagent's reported number is a claim; the extraction you run yourself is the oracle, and only the oracle feeds the gate. A model grading its own run (self-score, LLM judge in the mutable scope) is never the metric. No deterministic extraction exists → this skill does not apply; say so instead of climbing on vibes.

If required inputs are missing and no program.md supplies them, ask the user once, up front, for everything at once. After setup, never ask again.

Setup

Track this checklist:

- [ ] 1. Clock: date +%s, deadline computed, run count estimated
- [ ] 2. Branch: fresh autoresearch/<tag> from current HEAD, tree clean
- [ ] 3. Ledger TSV + progress file created in /tmp
- [ ] 4. Baseline recorded as best; extraction proven; noise floor set
- [ ] 5. Executor pin recorded

1. Clock. Record start timestamp and deadline. Runs available ≈ duration ÷ (per-run budget + ~2 min overhead). Fewer than ~5 → tell the user now; the run will mostly measure noise.
2. Branch. git -C <repo> checkout -b autoresearch/<tag> from current HEAD. Must be fresh — if the branch exists or the tree is dirty, stop and tell the user. Every git command in this run uses git -C <repo> — never rely on cwd. This skill never runs git reset --hard, git clean, or git stash (the stash stack is shared with every other worktree).
3. Ledger. Everything lives in /tmp — never inside the target repo, so no reset, checkout, or subagent commit can ever touch the record. <L> = /tmp/autoresearch-<tag>-<timestamp> is the prefix for all of it:
   • <L>.tsv — the ledger TSV, header row, tab-separated: n commit <metric> cost status description — status is baseline, keep, keep (simplicity), discard, discard (noise), discard (scope), discard (cost), or crash; cost is the cost-tolerance value if declared, else 0. Crashes log metric NA, never a number. The ledger TSV is the source of truth: current best = the last baseline/keep/keep (simplicity) row.
   • <L>.md — progress file: goal, focus (verbatim), metric spec, commands, scopes, noise floor, start, deadline, executor pin, a ## Queue of untried hypotheses, and an ## Experiments section. Narrative mirror — when it disagrees with the TSV, the TSV wins.
   • <L>-exp<N>.log — one run log per experiment (-exp<N>b.log for a confirmation re-run). Logs are never overwritten, so crashes need no copying and every number stays re-checkable.
4. Baseline. Dispatch a subagent to run the experiment command unmodified into <L>-exp0.log, <L>-exp0b.log and, if one run is under ~5% of the duration, <L>-exp0c.log. Extract each yourself: every extraction must print exactly one number — if not, fix the extraction command with the user now; this is the last moment you can.
   • Best = the median of the baseline values (two runs: their mean).
   • Noise floor (if not given) = max − min of the baseline values. 0 means the harness is deterministic: any strict improvement wins and no confirmation runs are needed.
   • Record row 0 in the TSV (baseline), and best + noise floor in the progress file.
   • Baseline crashes: fix-dispatch up to 3 times (fixes limited to the mutable scope — anything else escalates immediately), then escalate — there is no run without a baseline.
5. Executor pin. Record host and hardware in the progress file. If the run moves to another machine, re-run the baseline and start a new best — numbers do not transfer across executors.

Setup is the only phase where user interaction is allowed. Afterward the loop runs lights-out until the deadline.

The Experiment Loop

Before every dispatch: date +%s vs deadline. Remaining time less than one per-run budget → Final Summary.

1. Dispatch

One subagent, blocking. Strict template — fill the brackets, keep the structure:

You are running ONE experiment in an autonomous research loop.

Repo: <path>, branch autoresearch/<tag>, currently at the best-known commit.
Mutable scope: <files>. Frozen scope: <files> — read, never modify.
Metric: <name>, <lower|higher> is better. Current best: <value>.
Noise floor: <value> — a gain smaller than this is not a gain.
Research focus: <verbatim focus, or "none: full mutable scope is fair game">.
Every hypothesis you consider must stay inside the focus.

Read <L>.md and <L>.tsv FIRST. They list every experiment already tried.
Do NOT repeat any of them, including failures — a discard is information,
not an invitation. Prefer the top untried item in the ## Queue, if any.

Your task:
1. Pick ONE untried hypothesis likely to beat the best by more than the
   noise floor.
2. Implement it in the mutable scope. Minimal, focused diff.
3. Commit ONLY mutable-scope paths: git -C <repo> add <files>, then
   git -C <repo> commit -m "<the hypothesis>". Never git add -A.
4. In ONE shell invocation, run and extract:
     cd <repo> && timeout -k 30 <2x budget> <experiment command> \
       > <L>-exp<N>.log 2>&1; echo "exit=$?"; <extraction command on that log>
   Never let run output into your context — redirect, then extract.
   exit=124 or 137 = timed out: treat as a crash.
5. Empty extraction = crash: read `tail -n 50 <L>-exp<N>.log` — never more,
   never `cat`. Trivial cause (typo, missing import): fix, commit, re-run
   once into the same log path. Fundamentally broken idea: stop and report.
6. Report the FINAL commit hash (git -C <repo> rev-parse HEAD), never the
   first one.

Return exactly:
- Hypothesis (one line)
- Commit hash
- Metric value (or CRASH + the last 5 error lines)
- One suggested next experiment based on what you observed

Do NOT decide keep-vs-discard, reset or move the branch, edit <L>.tsv or
<L>.md, or touch any file outside the mutable scope. The orchestrator gates.

Pass ledger paths, never contents. No deadline awareness for subagents. Never paste "lessons from past runs" into the prompt as prose — the ledger is the record, and the subagent reads it as data.

2. Verify

Never gate on the report alone. One shell call, no turns in between:

<extraction command on <L>-exp<N>.log>;       # the oracle value
git -C <repo> rev-parse HEAD;                 # must equal the reported commit
git -C <repo> status --porcelain;             # empty, apart from user-named byproducts
git -C <repo> diff --name-only <best>..HEAD;  # every path inside the mutable scope
<cost extraction, if a cost tolerance is declared>

• Oracle empty, or different from the reported number → the report was a hallucination: crash.
• HEAD ≠ reported commit → an unreported commit exists: crash.
• Uncommitted changes inside the mutable scope → the number measured code that is not the commit: crash.
• Any path outside the mutable scope, committed or dirty → discard (scope), whatever the metric says.

3. Gate

Take the first row that matches. margin = improvement over best in the metric's direction (positive = better); floor = noise floor.

Confirm (row 4). Dispatch a subagent: "Run <experiment command> on commit <hash>, unmodified, into <L>-exp<N>b.log, using the step-4 shell invocation. Change nothing. Return the extracted value." Extract it yourself. Re-gate with the worse of the two values, skipping row 4. One confirmation run is cheaper than a false best that poisons every later comparison.

Simplicity (row 6) is the one judgment call you own: equal-within-noise metric, less code or cost. A marginal gain bought with disproportionate complexity is a discard. In doubt, the metric wins.

On any keep: the branch stays; best = this commit and value.

On any discard or crash, in order:

1. Dirty tree? Preserve it as a commit, never a stash: git -C <repo> add -A && git -C <repo> commit -m "wip exp-<N>".
2. git -C <repo> update-ref refs/autoresearch/<tag>/exp-<N> HEAD — the attempt stays reachable for morning review.
3. git -C <repo> reset --keep <best commit> — never --hard.

Every experiment: remove user-named byproducts so runs stay independent.

4. Log

Append one row to the ledger TSV, then one entry to the progress file:

### Experiment N — <time>
- Hypothesis: <one line>
- Commit: <hash>
- Metric: <value> (best: <value>)
- Status: <status from the gate table>
- Suggested next: <from the subagent>

Add the suggestion to the ## Queue if it is untried. Return to the clock check.

Resume

Context compacted, session restarted, or you lost track? Never guess:

1. ls -t /tmp/autoresearch-<tag>-*.tsv | head -1 → the ledger; read it and its .md progress file.
2. Best = the last baseline/keep/keep (simplicity) row. N = last row + 1.
3. git -C <repo> rev-parse HEAD ≠ best commit → an experiment was interrupted before its gate finished. No TSV row for it yet → log it as crash. Then run the discard steps (they are safe to repeat).
4. Re-check the clock. Continue the loop.

Stall Recovery

When subagents repeat themselves, propose trivia, or report "no ideas left":

0. Replay the ledger first. Keeps, discards, and crashes per hypothesis area are already in the TSV. Decide the next rung from those numbers; never spend a run to test a dispatch strategy.
1. Dispatch an ideation subagent: read the full ledger and both scopes, return 5-10 concrete untried hypotheses inside the focus — including combinations of near-misses (discard (noise) rows first) and radical structural changes. Write them to the ## Queue.
2. Escalate ambition. Early experiments tweak knobs; later ones change structure. The ledger shows which rung you are on.
3. Widen an exhausted focus. If ideation returns nothing viable twice in a row, widen to the full mutable scope and log the widening loudly.
4. Rewind sparingly. Resetting best to an earlier commit to escape a local optimum is allowed but should be very rare. Log it loudly.

Running out of ideas is never a reason to stop.

Preventing Premature Exit

Every one of these thoughts is a trap:

Any variation of "maybe stop" → check the clock and dispatch again.

Final Summary

Only after the deadline (let the in-flight experiment finish and gate it — never kill it for the deadline):

1. Confirm the branch sits at the best commit (git -C <repo> rev-parse HEAD vs the TSV's current best).
2. Re-measure the best if any keep happened: one unmodified run into <L>-final.log. The best was selected from many noisy trials, so its logged value is optimistic; report both.
3. Holdout, if declared: run it once on the baseline commit and once on the best commit. This is its only use — a holdout the loop sees becomes training data.
4. Append to the progress file and report:

## Summary
- Experiments: N total — K keeps, D discards, C crashes
- Baseline: <value> → Best: <logged value> (re-measured: <value>, noise floor <value>)
- Holdout: <baseline> → <best>, or "none declared"
- Branch: autoresearch/<tag> at <best commit>
- Kept changes: <one line each>
- Nearest misses worth a future run: <discard (noise) rows>
- Ledger: <L>.tsv, <L>.md
- Review: git -C <repo> log --oneline <base>..autoresearch/<tag>
          git -C <repo> diff <base>..autoresearch/<tag>
          git -C <repo> for-each-ref refs/autoresearch/<tag>/

Leave the branch checked out at the best commit. Never merge, push, or open a PR — that is the user's morning decision. To publish a session record (karpathy PR 44 style), the user can copy <L>.tsv into the branch.

Red Flags — STOP and Reread This Skill

• You are editing a file in the target repo
• Two experiment subagents are running at once
• You gated on a metric value you did not extract from the log yourself
• A keep happened that is not a gate-table row 5 or row 6
• You typed git reset --hard, git clean, git stash, or any git command without -C <repo>
• A diff touched the frozen scope and you gated on the metric anyway
• git status --porcelain was non-empty and you dispatched anyway
• A run log or ledger file was written inside the target repo
• You are composing a message to the user before the deadline
• You have not run date +%s since the last subagent returned
• You stated the current best from memory instead of the TSV
• The run moved to another machine and you kept comparing against old rows
