Auto Researching

Agent 2 — Metrics & Benchmarks: Search for existing benchmarks, test suites, evaluation scripts, and measurable metrics. Look for files with "bench", "test", "eval", "metric" in the name. Read any that exist and report what metrics are already being measured and how they're run.

Wait for both agents to return before proceeding.

Setup Phase

1. Parse and validate research.json
2. Verify autoresearch/<tag> branch doesn't exist — if it does, append -2, -3, etc.
3. git checkout -b autoresearch/<tag>
4. Read all readonly_files and modifiable_files for context
5. Run setup_check if configured; halt on failure
6. Add results.tsv and run.log to .gitignore
7. Initialize results.tsv with tab-separated header row
8. Baseline run: run the experiment unmodified, log as keep | baseline
9. Tell user setup is complete. This is the last interaction. From here, fully autonomous.

The Experiment Loop

LOOP FOREVER. NEVER stop. NEVER ask permission to continue.

The user may be asleep. They expect you to run indefinitely until manually stopped.

1. Review results.tsv for trends. Re-read modifiable files for current state.

2. Form ONE hypothesis. Prefer changes that are:
   - Informed by past results
   - Meaningfully different from recent experiments
   - Simple — tiny gain + ugly complexity = not worth it

3. Edit ONLY modifiable_files. No new dependencies unless config allows it.

4. Git commit with short description. Do NOT commit results.tsv or run.log.

5. Run experiment: redirect ALL output to run.log (NEVER flood context).
   Kill if exceeds timeout_seconds.

6. Extract metric via grep. If empty → crashed.

7. Crashes: read last 50 lines of log. Trivial fix → retry (max 2-3 attempts).
   Broken idea → log as crash, revert, move on.

8. Append tab-separated row to results.tsv (untracked, survives git resets).

9. Keep or discard:
   - IMPROVED → keep commit, branch advances
   - EQUAL or WORSE → git reset --hard HEAD~1
   - Exception: equal metric + simpler code → keep
   - Exception: tiny gain + lots of ugly code → discard

10. Every 10 experiments, print a progress summary.

11. GOTO 1

Critical Rules

• Protect your context window — see CONTEXT.md. This is the #1 risk for long-running sessions. Always redirect output, use grep not read, only tail on crash.
• results.tsv is your memory — it survives git resets and contains full history. Re-read it when you need to review past experiments.
• One change per experiment — test one hypothesis at a time.
• When stuck — see STRATEGIES.md for research tactics.
