Autoresearch: Autonomous Improvement Loop

Run a self-directed improvement loop on any measurable codebase metric. Inspired by Andrej Karpathy's approach to systematic, measurable iteration.

Core Protocol

For each iteration:
  1. REVIEW  — Read git log + results log (what worked/failed/untried)
  2. PICK    — Choose ONE focused change (highest expected impact)
  3. MAKE    — Implement the change (single file if possible)
  4. TEST    — Run test suite (must pass or revert)
  5. COMMIT  — Git commit with "experiment:" prefix BEFORE verification
  6. VERIFY  — Run mechanical benchmark/metric
  7. DECIDE  — If improved → keep. If worse → git revert
  8. LOG     — Append result to TSV log
  9. REPEAT  — Go to step 1

Setup

1. Define Your Metric

The loop needs a mechanical, numeric metric — no subjective evaluation.

Examples:

• Benchmark score (weighted total)
• Test pass rate
• Response time (p50, p95)
• Bundle size
• Lines of code
• Error count

2. Create Results Log

Create a TSV file to track iterations:

iteration	commit	metric	delta	status	description
0	baseline	4.55	0	baseline	Initial measurement

3. Create Baseline

# Run your metric measurement
python tests/bench.py --runs 3 --output tests/bench-results-baseline.json

# Record baseline in TSV

Loop Rules

Rule 1: ONE Change Per Iteration

Each iteration makes exactly one focused change. This enables precise failure attribution.

Rule 2: Tests Must Pass

Run the full test suite after every change. If tests fail, fix them before proceeding. Never skip tests.

Rule 3: Commit Before Verification

Git commit with experiment: prefix BEFORE running the benchmark. This preserves the exact state for later analysis.

Rule 4: Mechanical Metrics Only

Never evaluate subjectively. Use automated scoring, timing, or counting. If you can't measure it, don't optimize it.

Rule 5: Keep or Revert

After benchmark:

• Improved → Keep the commit, log as keep
• Unchanged → Keep if the change has other benefits, log as neutral
• Regressed → git revert HEAD, log as reverted

Rule 6: Git as Memory

Before each iteration, read:

• git log --oneline -20 — recent changes
• Results TSV — what worked and what didn't
• Don't repeat failed approaches unless you have a genuinely new angle

Rule 7: Think Harder When Stuck

If the last 3 iterations showed no improvement:

1. Re-read the metric formula — what exactly determines the score?
2. Re-read the raw data — where are the actual bottlenecks?
3. Try a radical approach (different algorithm, different architecture)
4. Consider if the metric ceiling has been reached

Rule 8: Track Everything

The TSV log is your lab notebook. Include enough detail to understand each experiment months later.

Task Management

Use Claude Code's TaskCreate/TaskUpdate for the work queue:

TaskCreate: "Improve speed via connection pooling"
  → status: in_progress when working
  → status: completed when done
  → description updated with results

Group related changes into rounds:

• Round 1: Low-hanging fruit (config changes, test fixes)
• Round 2: Architecture changes (pooling, caching)
• Round 3: Algorithm improvements (smart fallbacks)

Example: Flarecrawl Benchmark Loop

Metric

Weighted benchmark score across 5 dimensions (speed, content, cost, reliability, output quality).

Iterations

Iter  Commit   Score  Delta  Status  Description
0     base     4.55   0      base    Initial scores
1     b47567c  -      -      keep    networkidle0 for JS rendering
2     30f48b4  -      -      keep    Enrich metadata (5 fields)
3     4376cf7  -      -      keep    File-based response cache (7x speedup)
4     c807746  4.15   -0.40  revert  networkidle2 caused timeouts
5     c6c4ca1  4.35   -0.20  keep    Reverted networkidle, added --wait-until flag
7     aa8becc  4.45   +0.10  keep    Smart JS fallback with retry
9     b8a15d4  -      -      keep    httpx connection pooling (HTTP/2)
10    08feecc  -      -      keep    Fix known_text test config
11    5eb173a  -      -      keep    Metadata enrichment to 11 fields
12    round2   4.80   +0.35  keep    Content accuracy + output quality → 5

Key Lessons

• networkidle0 as default was a bad idea — some pages never reach idle (analytics). Smart fallback with timeout + retry was the solution.
• Test config bugs matter — blog.cloudflare known_text was wrong ("Browser Rendering" vs "browser-rendering"). Fixing the test gave a free +1 to content_accuracy.
• Metadata is cheap — parsing headings/links/wordcount from existing markdown costs zero API calls but pushed output_quality from 4 to 5.
• Connection pooling — replacing one-shot httpx.get() with persistent httpx.Client() reuses TCP+TLS across requests.

Anti-Patterns

Anti-Pattern	Why It Fails	Instead
Multiple changes per iteration	Can't attribute improvement/regression	One change at a time
Subjective evaluation	"Looks better" isn't measurable	Mechanical metrics only
Deleting failed experiments	Lose information about what doesn't work	Git revert preserves history
Optimizing the wrong thing	Spending hours on a 10% weight dimension	Prioritize by weight × gap
Ignoring test failures	Regressions compound	Tests must pass every iteration
Not logging	Can't learn from past iterations	TSV log is mandatory

Invocation

/autoresearch

# Or with specific target:
"Run an autoresearch loop to improve [metric] by [approach]"

The skill works best when:

1. You have a clear, measurable metric
2. The codebase has a test suite
3. Changes can be made incrementally
4. Git is available for version control
