+description: "Autonomous experiment loop that runs overnight research without human intervention. Inspired by Karpathy's autoresearch: agent modifies a target file, runs an evaluation, keeps improvements (git commit), discards failures (git reset), and loops indefinitely. Use when the user wants to: autonomously optimize ML training code, improve prompts by eval score, benchmark-drive code performance, or run any experiment loop with a measurable metric. Requires: a target file to modify, a fixed evaluation function, and a git repo."

+# Autoresearch Agent
+
+> You sleep. The agent experiments. You wake up to results.
+
+Autonomous experiment loop inspired by Andrej Karpathy's [autoresearch](https://github.com/karpathy/autoresearch). The agent proposes changes, runs a fixed-time evaluation, keeps improvements via git, discards failures, and loops indefinitely — no human in the loop.
+
+**Works for any domain with a measurable metric:**
+- ML training optimization (original use case — optimize `train.py` by `val_bpb`)
+- Prompt engineering (optimize system prompts by LLM-eval quality score)
+- Code performance (optimize a module by benchmark runtime/score)
+- Agent skill improvement (optimize `SKILL.md` by task completion rate)
+
+---
+
+## Before Starting
+
+Check for `program.md` in the project root. If it exists, read it — it defines the experiment objectives, constraints, and what the agent should optimize. Only ask for what's missing.
+
+If no `program.md` exists, run the **Setup Wizard** below.
+
+---
+
+## Setup Wizard
+
+Answer these 5 questions to configure the experiment:
+
+### 1. What are we optimizing?
+The **target** — one file the agent is allowed to modify:
+- `train.py` — ML training loop (Karpathy-style)
+- `prompt.md` — system prompt for an LLM
+- `src/module.py` — a specific code module
+- `SKILL.md` — an agent skill definition
+
+### 2. What's the metric?
+A **single number** that defines success. Lower or higher = better:
+- `val_bpb` — validation bits per byte (ML, lower is better)
+- `eval_score` — LLM quality score 0-100 (higher is better)
+- `p50_ms` — median latency in milliseconds (lower is better)
+- `pass_rate` — test pass rate 0-1 (higher is better)
+
+### 3. What's the time budget per experiment?
+How long one experiment run takes:
+- `5m` — fast iteration (Karpathy default, ~12 experiments/hour)
+- `10m` — moderate (6/hour)
+- `30m` — slow but thorough (2/hour)
+
+### 4. What can the agent change?
+Constraints on the target file:
+- Architecture only? Hyperparameters only? Everything?
+- What packages/imports are available?
+- What's explicitly off-limits?
+
+### 5. What's the evaluation function?
+How we score each experiment:
+- Fixed script that outputs the metric (e.g. `python evaluate.py`)
+- API call that returns a score
+- Test suite with a pass rate
+
+Once answered, run: `python scripts/setup_experiment.py` to initialize.
+
+---
+
+## The Three Files
+
+Every autoresearch project has the same structure:
+
+```
+project/
+├── program.md       ← Human writes this: objectives, constraints, strategy
+├── target.*         ← Agent modifies this: the thing being optimized
+├── evaluate.py      ← Fixed: the measurement function (never touch)
+├── results.tsv      ← Auto-generated: experiment log (git-tracked for continuity)
+└── scripts/
+    ├── setup_experiment.py   ← Initialize a new run
+    ├── run_experiment.py     ← Execute one experiment iteration
+    └── log_results.py        ← Record results to TSV
+```
+
+### `program.md` — Your Research Directions
+Write this once. The agent reads it before every experiment. It should contain:
+- **Goal:** What you want to achieve (minimize loss, maximize score, simplify code)
+- **Strategy:** What directions to explore first
+- **Constraints:** What the agent cannot change
+- **Stopping criteria:** When a result is "good enough"
+
+See `references/program-template.md` for domain-specific templates.
+
+### Target File — The Only File the Agent Edits
+Whatever you're optimizing. Strict scope: **one file, one metric**.
+
+### `evaluate.py` — Fixed Evaluation (Never Modified)
+The measurement function. Outputs the metric value to stdout. The agent reads this output — it cannot change how it's measured.
+
+---
+
+## The Experiment Loop
+
+Run: `python scripts/run_experiment.py --loop`
+
+```
+LOOP FOREVER:
+
+1. Read program.md for current strategy
+2. Review git history: what has been tried? What worked?
+3. Propose ONE change to the target file
+4. Apply the change
+5. git commit (with descriptive message)
+6. Run evaluation: python evaluate.py > run.log 2>&1
+7. Parse metric from run.log
+8. If metric improved → ADVANCE (keep commit, log "keep")
+9. If metric equal/worse → REVERT (git reset, log "discard")
+10. If crash → attempt fix, if unfixable log "crash" and revert
+11. Update results.tsv
+12. Go to 1
+```
+
+### Rules (from Karpathy's original)
+
+- **NEVER STOP** — once the loop starts, do not ask the human if you should continue. They may be asleep. Run until manually interrupted.
+- **Simplicity criterion** — a small improvement that adds ugly complexity is not worth it. Removing code and getting equal results is a win.
+- **One change per experiment** — don't change 5 things at once. You won't know what worked.
+- **Crash = discard** — OOM, error, timeout → log "crash", revert, move on.
+- **Time limit** — if run exceeds 2.5× the time budget, kill it and treat as crash.
+- **No new dependencies** — only use what's already available.
+
+---
+
+## Results Log
+
+`results.tsv` (tab-separated, not git-tracked):
+
+```
+commit  metric  status  description
+a1b2c3d 0.9979  keep    baseline
+b2c3d4e 0.9932  keep    increased learning rate
+c3d4e5f 1.0050  discard switched to GeLU (worse)
+d4e5f6g 0.0000  crash   doubled model width (OOM)
+```
+
+Run `python scripts/log_results.py --summary` for a visual summary.
+
+---
+
+## Domain-Specific Configurations
+
+### ML Training (Karpathy-style)
+```yaml
+target: train.py
+evaluate: uv run prepare.py --eval-only
+metric: val_bpb (lower is better)
+time_budget: 5m
+git_branch: autoresearch/{date}-{tag}
+```
+
+### Prompt Engineering
+```yaml
+target: prompt.md
+evaluate: python evaluate.py --model gpt-4o --test-cases tests/
+metric: eval_score (0-100, higher is better)
+time_budget: 2m
+git_branch: prompt-research/{date}
+```

+
+See `references/experiment-domains.md` for full setup guides per domain.
+

+
+## Scripts
+
+| Script | Purpose |
+|--------|---------|
+| `setup_experiment.py` | Initialize a new research run: create branch, verify setup, baseline run |
+| `run_experiment.py` | Execute the autonomous loop (single run or `--loop` for infinite) |
+| `log_results.py` | Record results to TSV; `--summary` prints progress table |
+
+---
+
+## Installation
+
+### One-liner (any tool)
+```bash
+git clone https://github.com/alirezarezvani/claude-skills.git
+cp -r claude-skills/engineering/autoresearch-agent ~/.claude/skills/
+```
+
+### Multi-tool install
+```bash
+# Clone the repo, then use the convert script for your tool:
+./scripts/convert.sh --skill autoresearch-agent --tool codex|gemini|cursor|windsurf|openclaw
+```
+
+### OpenClaw
+```bash
+clawhub install autoresearch-agent
+```
+
+---
+
+## Proactive Triggers
+
+Flag these issues without being asked:
+
+- **No `evaluate.py` exists** → Experiment can't run. Offer to create one from a template.
+- **Target file has no git history** → `git init` and commit baseline first.
+- **Metric direction unclear** → Ask: is lower or higher better? Agent must know before starting.
+- **Time budget too short** → If evaluation takes longer than budget, experiments will always crash.
+- **`results.tsv` in `.gitignore`** → It shouldn't be. The log must persist across sessions.
+- **Agent modifying `evaluate.py`** → Hard stop. This invalidates all comparisons.
+
+---
+
+## Related Skills
+
+- **self-improving-agent**: Use when improving an agent's own memory/rules over time. NOT for structured experiment loops with metrics.
+- **senior-ml-engineer**: Use for ML architecture decisions and training setup. NOT for autonomous overnight loops.
+- **skill-security-auditor**: Use to audit skills before publishing. NOT for optimization loops.
+- **tdd-guide**: Use when you want tests to drive development. Complementary — can use tests as the evaluation function.

+# Experiment Domains Guide
+
+## Domain 1: ML Training (Karpathy-style)
+
+**Best for:** LLM/neural net training optimization on a single GPU
+
+**Requirements:**
+- NVIDIA GPU (H100 recommended, A100/RTX also work)
+- CUDA + PyTorch
+- `uv` package manager
+- ~50GB disk (training data)
+
+**Setup:**
+```bash
+# Clone autoresearch repo (the ML training environment)
+git clone https://github.com/karpathy/autoresearch my-ml-research
+cd my-ml-research
+uv sync
+uv run prepare.py  # one-time data download + tokenizer (~2 min)
+
+# Initialize autoresearch skill
+cp -r ~/.claude/skills/autoresearch-agent/scripts ./scripts
+
+# Configure
+python scripts/setup_experiment.py --domain ml --tag mar13
+```
+
+**Metric:** `val_bpb` — validation bits per byte. Lower = better model.
+
+**What the agent can change in `train.py`:**
+- Model depth, width, attention heads
+- Learning rate, scheduler, warmup
+- Optimizer (Muon, AdamW, variants)
+- Batch size, gradient accumulation
+- Architecture (attention patterns, FFN type)
+
+**Tip for smaller GPUs (Mac M-series, RTX 3090 etc):**
+Karpathy recommends forks for non-H100 hardware. Lower `DEPTH` to 4, use TinyStories dataset, lower `MAX_SEQ_LEN` to 256.
+
+---
+
+## Domain 2: Prompt Engineering
+
+**Best for:** Optimizing system prompts for quality/accuracy/tone
+
+**Requirements:**
+- LLM API access (OpenAI, Anthropic, etc.)
+- Test cases with expected outputs
+- An LLM judge for scoring (can be same model)
+
+**Setup:**
+```bash
+mkdir my-prompt-research && cd my-prompt-research
+git init
+
+# Create prompt.md (the thing being optimized)
+echo "You are a helpful assistant." > prompt.md
+
+# Create evaluate.py (fixed — never modify)
+cat > evaluate.py << 'EOF'
+#!/usr/bin/env python3
+# Fixed evaluation harness — DO NOT MODIFY
+import json, sys
+from pathlib import Path
+
+PROMPT = Path("prompt.md").read_text()
+# Load test cases
+TEST_CASES = json.loads(Path("tests/cases.json").read_text())
+
+# Run prompt against test cases, score with LLM judge
+# ... (customize for your LLM + scoring logic)
+total = sum(score_case(PROMPT, case) for case in TEST_CASES)
+score = total / len(TEST_CASES) * 100
+print(f"eval_score: {score:.2f}")
+EOF
+
+# Initialize
+python scripts/setup_experiment.py --domain prompt --tag mar13
+```
+
+**Metric:** `eval_score` (0-100). Higher = better prompt.
+
+---
+
+## Domain 3: Code Performance
+
+**Best for:** Optimizing a specific hot module for speed
+
+**Requirements:**
+- A Python module with measurable performance
+- Existing tests (correctness must not regress)
+- A benchmark harness
+
+**Setup:**
+```bash
+cd my-project
+
+# Create benchmark.py (fixed — never modify)
+cat > benchmark.py << 'EOF'
+#!/usr/bin/env python3
+# Fixed benchmark — DO NOT MODIFY
+import time, statistics
+from src.module import your_function
+from tests.test_module import run_tests
+
+# Correctness check first
+if not run_tests():
+    print("TESTS FAILED")
+    sys.exit(1)
+
+# Benchmark
+data = generate_test_data(n=10000)
+times = []
+for _ in range(10):
+    t0 = time.perf_counter()
+    your_function(data)
+    times.append((time.perf_counter() - t0) * 1000)
+
+p50 = statistics.median(times)
+print(f"p50_ms: {p50:.2f}")
+print(f"p95_ms: {statistics.quantiles(times, n=20)[18]:.2f}")
+EOF
+
+python scripts/setup_experiment.py --domain code \
+  --target src/module.py \
+  --tag mar13
+```
+
+**Metric:** `p50_ms` — median latency. Lower = faster.
+
+---
+
+## Domain 4: Agent Skill Optimization
+
+**Best for:** Improving the quality of claude-skills SKILL.md files
+
+**Requirements:**
+- A SKILL.md to optimize
+- A task evaluation suite (15-20 standardized tasks)
+- An LLM judge for scoring
+
+**Setup:**
+```bash
+# Create a new skill research project
+mkdir skill-research-{skill-name} && cd skill-research-{skill-name}
+git init
+
+# Copy the skill to optimize
+cp ~/.claude/skills/{skill-name}/SKILL.md .
+
+# Create evaluate.py
+cat > scripts/skill_evaluator.py << 'EOF'
+#!/usr/bin/env python3
+# Fixed evaluator — DO NOT MODIFY
+# Runs SKILL.md against 15 standardized tasks using LLM judge
+# Outputs: pass_rate: 0.80 (etc.)
+EOF
+
+python scripts/setup_experiment.py --domain skill --tag mar13
+```
+
+**Metric:** `pass_rate` (0-1). Higher = better skill.
+
+---

+## ML Training (Karpathy-style)
+
+```markdown
+# autoresearch — ML Training
+
+## Goal
+Minimize val_bpb on the validation set. Lower is better.
+
+## What You Can Change (train.py only)
+- Model architecture (depth, width, attention heads, FFN ratio)
+- Optimizer (learning rate, warmup, scheduler, weight decay)
+- Training loop (batch size, gradient accumulation, clipping)
+- Regularization (dropout, weight tying, etc.)
+- Any self-contained improvement that doesn't require new packages
+
+## What You Cannot Change
+- prepare.py (fixed — contains evaluation harness)
+- Dependencies (pyproject.toml is locked)
+- Time budget (always 5 minutes, wall clock)
+- Evaluation metric (val_bpb is the ground truth)
+
+## Strategy
+1. First run: establish baseline. Do not change anything.
+2. Explore learning rate range (try 2x and 0.5x current)
+3. Try depth changes (±2 layers)
+4. Try optimizer changes (Muon vs. AdamW variants)
+5. If things improve, double down. If stuck, try something radical.
+
+## Simplicity Rule
+A small improvement with ugly code is NOT worth it.
+Equal performance with simpler code IS worth it.
+Removing code that gets same results is the best outcome.
+
+## Stop When
+val_bpb < 0.95 OR after 100 experiments, whichever comes first.
+```
+
+---
+
+## Prompt Engineering
+
+```markdown
+# autoresearch — Prompt Optimization
+
+## Goal
+Maximize eval_score on the test suite. Higher is better (0-100).
+
+## What You Can Change (prompt.md only)
+- System prompt instructions
+- Examples and few-shot demonstrations
+- Output format specifications
+- Chain-of-thought instructions
+- Persona and tone
+- Task decomposition strategies
+
+## What You Cannot Change
+- evaluate.py (fixed evaluation harness)
+- Test cases in tests/ (ground truth)
+- Model being evaluated (specified in evaluate.py)
+- Scoring criteria (defined in evaluate.py)
+
+## Strategy
+1. First run: baseline with current prompt (or empty)
+2. Add clear role/persona definition
+3. Add output format specification
+4. Add chain-of-thought instruction
+5. Add 2-3 diverse examples
+6. Refine based on failure modes from run.log
+
+## Evaluation
+- evaluate.py runs the prompt against 20 test cases
+- Each test case is scored 0-5 by GPT-4o
+- eval_score = average * 20 (maps to 0-100)
+- Run log shows which test cases failed
+
+## Stop When
+eval_score >= 85 OR after 50 experiments.
+```
+
+---
+
+## Code Performance
+
+```markdown
+# autoresearch — Performance Optimization
+
+## Goal
+Minimize p50_ms (median latency). Lower is better.
+
+## What You Can Change (src/module.py only)
+- Algorithm implementation
+- Data structures (use faster alternatives)
+- Caching and memoization
+- Vectorization (NumPy, etc.)
+- Loop optimization
+- I/O patterns
+- Memory allocation patterns
+
+## What You Cannot Change
+- benchmark.py (fixed benchmark harness)
+- Public API (function signatures must stay the same)
+- External dependencies (add nothing new)
+- Correctness tests (tests/ must still pass)
+
+## Constraints
+- Correctness is non-negotiable. benchmark.py runs tests first.
+- If tests fail → immediate crash status, no metric recorded.
+- Memory usage: p99 < 2x baseline acceptable, hard limit at 4x.
+
+## Strategy
+1. Baseline: profile first, don't guess
+2. Check if there's any O(n²) → O(n log n) opportunity
+3. Try caching repeated computations
+4. Try NumPy vectorization for loops
+5. Try algorithm-level changes last (higher risk)
+
+## Stop When
+p50_ms < 50ms OR improvement plateaus for 10 consecutive experiments.
+```
+
+---
+
+## Agent Skill Optimization
+
+```markdown
+# autoresearch — Skill Optimization
+
+## Goal
+Maximize pass_rate on the task evaluation suite. Higher is better (0-1).
+
+## What You Can Change (SKILL.md only)
+- Skill description and trigger phrases
+- Core workflow steps and ordering
+- Decision frameworks and rules
+- Output format specifications
+- Example inputs/outputs
+- Related skills disambiguation
+- Proactive trigger conditions
+
+## What You Cannot Change
+- scripts/skill_evaluator.py (fixed evaluation)
+- Test tasks in tests/ (ground truth benchmark)
+- Skill name (used for routing)
+- License or metadata
+
+## Evaluation
+- skill_evaluator.py runs SKILL.md against 15 standardized tasks
+- An AI judge scores each task: 0 (fail), 0.5 (partial), 1 (pass)
+- pass_rate = sum(scores) / 15
+
+## Strategy
+1. Baseline: run as-is
+2. Improve trigger description (better routing = more passes)
+3. Sharpen the core workflow (clearer = better execution)
+4. Add missing edge cases to the rules section
+5. Improve disambiguation (reduce false-positive routing)
+
+## Simplicity Rule
+A shorter SKILL.md that achieves the same score is better.
+Aim for 200-400 lines total.
+
+## Stop When
+pass_rate >= 0.90 OR after 30 experiments.
