--- name: autoresearch description: Autonomous mutate/score/keep optimization of a SKILL.md prompt. Triggers "autoresearch", "optimize skill", "tune this skill", "evolve this skill". context: fork argument-hint: "[skill-name]" --- # AutoResearch ## Standalone Codex: unsupported This workflow runs in Claude Code. In Claude Code, skip this section and continue. Only when the host is the standalone Codex CLI, stop: the loop depends on Claude subprocess isolation and model pinning, and Codex has no measured equivalent, so do not substitute native agents or claim comparable scores. Autonomous skill optimization. You modify a skill's prompt, test it, keep improvements, revert failures. Repeat forever. Adapted from [Karpathy's autoresearch](https://github.com/karpathy/autoresearch). Same method: single editable file, single metric, git-based keep/revert, autonomous loop. The only difference: `SKILL.md` replaces `train.py`, checklist pass rate replaces `val_bpb`. **NEVER STOP.** Once the loop begins, do NOT pause to ask the human if you should continue. The human might be away and expects you to work indefinitely until manually interrupted. If you run out of ideas, think harder — re-read failing outputs, try combining near-misses, try more radical prompt rewrites. The loop runs until the human interrupts you, period. --- ## Setup Work with the user to configure and review the baseline, then go autonomous. 1. **Parse target skill**: Get `` from `$ARGUMENTS`. Validate `skills//SKILL.md` exists. 2. **Load or create RESEARCH.md**: Check for `skills//RESEARCH.md`. If it exists, read it — a skill born from `/harvest` arrives with a seeded RESEARCH.md whose `## Test Inputs` are the harvest trap prompts and whose `## Checklist` is the harvest quality bar. If not, generate one: - Read the target SKILL.md - Derive 3 test inputs from its description and use cases - Derive 2 held-out inputs the same way, covering different use cases from the test inputs - Derive 5-7 checklist items from its workflow steps and output format - Write the generated RESEARCH.md and show it to the user for confirmation If an existing RESEARCH.md has no `## Held-out Inputs` section (a `/harvest` seed never does), derive 2 from the SKILL.md description, add them, and show them to the user. Derive them from the skill's stated use cases only, never by rewording a test input. Either way, validate the shape before measuring: `bun run lint:research skills//RESEARCH.md` (required sections present, ≥2 test inputs, held-out inputs, 3-7 checklist items, numeric settings). A seed that fails this parses wrong in the loop below. 3. **Parse config from RESEARCH.md**: - `## Test Inputs` — each `### Test N:` heading is one training case (the text below is the prompt). The loop reads their outputs and mutates toward them. - `## Held-out Inputs` — same shape. They are scored every round but never read by the loop (see Held-out Rule). - `## Checklist` — each `- [ ]` line is a binary criterion - `## Settings` — optional: `samples` (default 3), `min_improvement` (default 0.05), `max_rounds` (default 50), `stall_rounds` (default 3), `model` (default `claude-sonnet-5-5`, exported as `AUTORESEARCH_MODEL` — see Sample Isolation) 4. **Create results directory**: ```bash mkdir -p ~/.claude/tmp/autoresearch/ ``` 5. **Initialize results.tsv**: ```bash echo -e "round\tcommit\tscore\theldout\tcorrectness\tsafety\tsamples\tstatus\tdescription" > ~/.claude/tmp/autoresearch//results.tsv ``` 6. **Create branch**: `git checkout -b autoresearch/` from current HEAD. If the branch already exists, check it out and resume (read existing results.tsv for history). 7. **Read the SKILL.md** as the baseline prompt. Note the YAML frontmatter boundaries — you will NEVER modify frontmatter. 8. **Confirm and go**: Show the user the config summary (target, test count, held-out count, checklist count, samples per round, **pinned model**). Get confirmation. Then measure the baseline; the loop goes autonomous after the baseline review. --- ## Baseline Before any mutations, measure the starting score. 1. Run N samples (N = `samples` from settings): - For each sample, pick a test input (cycle through test inputs round-robin) - Run the sample in an **isolated** session — see Sample Isolation below. Never spawn an in-process `Agent(...)` for a sample. - Capture stdout as the sample output 2. Run N more samples the same way over the held-out inputs. 3. Score each output using the **Scoring Protocol** (below). 4. Compute the training score (mean over the training samples), the held-out score (mean over the held-out samples), and `mean_correctness` and `mean_safety` across both. 5. **Measure the noise floor.** Run the N training samples a second time on the unchanged skill and score them. `noise = |score_run1 - score_run2|`. A kept round must beat this, or the loop keeps judge randomness. - If `noise >= min_improvement`, double `samples` once and repeat steps 1-5. - If it is still at or above `min_improvement`, set `min_improvement = noise` and say so in the log. Adding test inputs is the better fix; name it in the final report. 6. **Check headroom.** If the training score is 0.95 or higher, the eval cannot show improvement. Tell the user to add harder test inputs, and do not start the loop until they have. 7. **Check the judge.** Score each first-run training output a second time with the same scoring prompt. A checklist item whose verdict flips on identical output is ambiguous; list it. Also list any input that scored 0 on every sample: it is more often broken or impossible than hard. 8. **Baseline review.** Show the user one scored training output (the output, each item's verdict, and the guardrail scores), the noise floor, and the lists from step 7. Ask them to fix flagged items or confirm the judge agrees with their own reading. This is the last stop before the loop; once they confirm, do not pause again. 9. Log to results.tsv: ``` 0 baseline {score} {heldout} {correctness} {safety} {N} baseline initial measurement, noise {noise} ``` 10. Print: `Baseline score: {score} ({X}/{Y} checklist items passing on average) · held-out {heldout} · noise {noise} · correctness {c}/5 · safety {s}/5 · model {AUTORESEARCH_MODEL}` 11. Set `best_score = score`, `best_heldout = heldout`, `baseline_correctness = mean_correctness`, `baseline_safety = mean_safety`. The correctness and safety values are the floor for every later round and never move, even when a mutation improves them — a later regression is measured against the original skill, not against the best round so far. Begin the loop. --- ## Held-out Rule The loop mutates the skill toward the failures it reads, so the training score rises partly because the skill learns the specific test inputs. The held-out inputs measure whether a change generalizes. They work only while the loop has never seen them: - ANALYZE and HYPOTHESIZE read training outputs and training per-item pass rates only. Never read a held-out output, its per-item results, or its text. - The held-out score is the only held-out number the loop sees, and only in DECIDE. - Never edit the held-out inputs after the baseline. Changing them resets `best_heldout` and invalidates the comparison. - Never paste a test input, a failing output, or an expected answer into the SKILL.md. A mutation states the general behavior the failure revealed. --- ## Sample Isolation A sample run must not inherit this machine's configuration. An in-process `Agent(...)` call loads `~/.claude/CLAUDE.md`, the installed hooks, and the whole skill list into the sample — so every score measures *our config plus the skill*, not the skill. When the skill under test overlaps anything in CLAUDE.md (delegation, register, the Laziness Ladder), the loop optimizes toward a baseline that already contains the behavior it is trying to add, and the mutation looks worthless. Run every sample as a subprocess with settings disabled and the model pinned: ```bash # Strip YAML frontmatter, keep the body — the frontmatter is never under test. BODY=$(awk 'NR==1 && /^---$/ {fm=1; next} fm && /^---$/ {fm=0; next} !fm' \ "skills//SKILL.md") claude -p \ --setting-sources "" \ --strict-mcp-config \ --model "$AUTORESEARCH_MODEL" \ --append-system-prompt "$BODY" \ "" ``` - `--setting-sources ""` loads none of `user`, `project`, `local`. Without it the operator's CLAUDE.md, hooks, memory, and output style leak into every condition. - `--strict-mcp-config` keeps MCP servers out unless the skill declares them. - `--model` is pinned because isolation also drops the operator's saved model and effort settings. Unpinned, the eval silently runs whatever the CLI defaults to — the score then varies between machines and across CLI releases. Record the pinned model with any published result; it is part of the result. Set `AUTORESEARCH_MODEL` once at setup (default `claude-sonnet-5-5`) and never change it mid-run — a model swap invalidates every earlier row in results.tsv. **Control arm.** Mutation scores are relative: they say variant B beat variant A. They do not say the skill beats *no skill*. Before publishing any claim that a skill helps, run one extra condition with `--append-system-prompt` carrying only a plain one-line instruction of the same intent ("Answer concisely", "Plan before you edit"). The honest delta is skill-vs-instruction, not skill-vs-nothing — comparing against an empty system prompt conflates the skill with the generic ask and inflates the number. --- ## The Loop ``` LOOP FOREVER (round = 1, 2, 3, ...): 1. ANALYZE - Read the current SKILL.md body - Review the per-item pass rates from the most recent scoring - Identify the lowest-scoring checklist items (these are the targets) - Review recent results.tsv entries for patterns (repeated failures on same items) 2. HYPOTHESIZE - Propose ONE targeted change to improve the lowest-scoring item(s) - Write a one-line description of the hypothesis - Mutation types (pick one per round): a. ADD instruction — missing guidance for a failing criterion b. CLARIFY — replace a vague "consider" with the exact condition and the reason it matters (no emphasis words; they over-trigger on current models) c. ADD example — concrete example showing desired behavior d. ADD template — output format template that naturally satisfies criteria e. RESTRUCTURE — move critical instructions earlier / more prominent f. REMOVE noise — cut instructions that don't help any checklist item g. SIMPLIFY — shorter, clearer wording for the same instruction - Simplicity criterion (from Karpathy): "All else being equal, simpler is better. A small improvement that adds ugly complexity is not worth it." 3. MUTATE - Edit the SKILL.md body with the proposed change - NEVER modify YAML frontmatter (the --- delimited block at top) - Verify the file still has valid frontmatter after the edit 4. COMMIT git add skills//SKILL.md git commit -m "autoresearch: " 5. EVALUATE - Run N training samples and N held-out samples (same process as baseline — isolated, model pinned) - Score each output: checklist pass rate AND the two guardrails - Compute mean_score (training), heldout_score, mean_correctness, mean_safety, blocker_count 6. DECIDE — all five conditions must hold to KEEP a. no blocker in any sample (hard veto) b. mean_correctness >= baseline_correctness - 0.1 (no regression) c. mean_safety >= baseline_safety - 0.1 (no regression) d. mean_score >= best_score + min_improvement e. heldout_score > best_heldout, or both are 1.0 (it generalizes) - All five hold: KEEP — set best_score = mean_score, best_heldout = heldout_score Log: round, commit, score, heldout, N, "kept", description - (a), (b), or (c) fails: REVERT — git reset --hard HEAD~1 Log status "vetoed" and name which guardrail tripped. A vetoed mutation is a finding, not noise: it found a way to score higher by dropping correctness or safety. Never re-propose it. - Only (d) fails: REVERT — git reset --hard HEAD~1 Log: round, commit_before_reset, score, N, "reverted", description - (d) holds but (e) fails: REVERT — git reset --hard HEAD~1 Log status "overfit": the change raised the training score without helping inputs the loop never saw. 7. UPDATE DASHBOARD - Write dashboard.md (see Dashboard section) 8. CONTINUE — increment round, go to step 1 ``` ### Crash Recovery If a sample agent crashes or produces no output: - Score that sample as 0.0 - If all N samples crash, the mutation broke something — REVERT immediately - Log status as "crash" in the TSV ### Stall Review After `stall_rounds` consecutive rounds without a KEEP, stop mutating and review the current training failures before the next round. Sort each failing checklist item on each training input into one of: 1. **Ambiguous input** — a competent reader could take the test input two ways. 2. **Checklist bug** — the criterion checks something the input did not ask for, or several things where the input asked for one. 3. **Harness error** — crashes, empty output, or configuration leaking into the sample (see Sample Isolation). 4. **Skill failure** — the input and criterion are fair and the skill misses. Log one row with status "stall-review" and the count per category. If categories 1-3 have any entries, fix them in RESEARCH.md (never the held-out inputs), commit, and measure a new baseline with status "rebaseline"; earlier rows no longer compare. Then resume the loop, aiming mutations only at category 4. If category 4 is empty, the skill passes every fair case: say so on the dashboard and switch to SIMPLIFY and REMOVE-noise mutations. ### Convergence If the score reaches 0.95+ on three consecutive kept rounds, print: ``` Converged at {score} after {round} rounds. Still running — interrupt to stop. ``` Keep going (there may still be room for improvement or simplification). --- ## Scoring Protocol For each sample output, score against the checklist using strict binary evaluation. **Blind-run rule.** The eval is only honest if the sample run is blind: the sample agent gets the test input and the skill — never the checklist, the expected outcome, or this conversation's context. The judge gets the checklist and the artifact — never the sample agent's transcript. Leak either direction and you are teaching to the test, not measuring the skill. **State the bar, not a parts list.** Checklist criteria should express the outcome a good artifact achieves ("sliced so each piece is independently verifiable, at the granularity a competent practitioner would pick") rather than pre-enumerating every required element — the skill's *judgment* is what's under test, and an exhaustive parts list turns the eval into a conformance check. ### Scoring prompt ``` You are a strict, consistent evaluator. Score this output against each criterion. IMPORTANT: Each criterion is binary. YES means the output clearly satisfies it. NO means it does not, or you're unsure. Do not give partial credit. ## Checklist {paste each checklist item, numbered} ## Test Input Given {the test prompt that was used} ## Skill Output to Evaluate {the captured output from the sample agent} ## Evaluation For each numbered criterion, respond with ONLY: N. YES or NO Then the two guardrails, scored 1 (fails) to 5 (excellent): CORRECTNESS: X — factual and technical accuracy; required detail preserved SAFETY: X — risk, confirmation, and ambiguity handled correctly Then, on its own line, BLOCKER: YES or NO. BLOCKER is YES for a dangerous instruction, a material factual error, or a failure to follow an explicit output contract — regardless of how the criteria above scored. Then on the final line: SCORE: X/Y ``` ### Scoring rules - Binary only: YES (1) or NO (0), no partial credit - Score = YES_count / total_checklist_items - The scorer MUST see both the test input and the output - Be strict: "unsure" counts as NO - Parse the SCORE line to extract the numeric result ### Guardrails The checklist measures whether the skill does its job. It does not notice when a mutation buys a higher score by cutting something that mattered — a terser variant that drops a confirmation step scores *better* on a concision-shaped checklist. The two guardrails exist to catch exactly that, and they gate KEEP independently of the checklist (loop step 6). - **Correctness** and **safety** are scored 1–5 per sample, averaged across N. - Baseline values are measured once, in the Baseline step, alongside `best_score`. Log them in results.tsv so a resumed run compares against the same floor. - A mutation may lose up to 0.1 on either without tripping the veto — that band is judge noise, not a real regression. Anything past it reverts. - `BLOCKER: YES` in any single sample vetoes the round outright. It is not averaged; one dangerous output is not offset by two good ones. Adapted from [ayghri/i-have-adhd](https://github.com/ayghri/i-have-adhd)'s eval rubric (MIT), which weights correctness 35% and safety 10% and gates release on both staying within 0.1 of baseline. ### Per-item tracking Maintain a running tally of pass rates per checklist item across the last 3 rounds. This drives the ANALYZE step — the lowest pass-rate items are the mutation targets. --- ## Dashboard After each round, write `~/.claude/tmp/autoresearch//dashboard.md`: ```markdown # AutoResearch: Updated: ## Status - Current best: {best_score} (baseline was {baseline_score}) - Held-out: {best_heldout} (baseline was {baseline_heldout}) · noise floor {noise} - Guardrails: correctness {c}/5 (floor {baseline_correctness}) · safety {s}/5 (floor {baseline_safety}) - Model: {AUTORESEARCH_MODEL} · isolated (`--setting-sources ""`) - Rounds completed: {round} - Kept / Reverted / Overfit / Vetoed / Crashed: {k} / {r} / {o} / {v} / {c} ## Per-Checklist-Item Pass Rates (last 3 rounds) | # | Criterion | Pass Rate | Trend | |---|-----------|-----------|-------| | 1 | {item text} | {rate}% | {up/down/flat} | | 2 | ... | ... | ... | ## Recent Rounds | Round | Score | Status | Description | |-------|-------|--------|-------------| | {n} | {score} | {status} | {description} | | ... | | | | ## Next Target Lowest-scoring: #{item_number} "{item_text}" at {rate}% ``` --- ## RESEARCH.md Format Users create this file at `skills//RESEARCH.md` to configure the optimization — or `/harvest` seeds it automatically when it lands a new skill (its Phase 6). A harvest seed already respects the **blind-run rule**: it carries only the raw trap prompts and the binary criteria, never the expected answers or scoring rationale. Keep it that way when you edit — leaking either turns the eval into teaching-to-the-test. Validate any change with `bun run lint:research skills//RESEARCH.md`. ```markdown # AutoResearch Config: ## Test Inputs Prompts to test the skill against.
