## What it does

The skill executes a single controlled step of an experiment loop. It checks out the `autoresearch/{domain}/{name}` branch, inspects `config.cfg`, and reviews past attempts in `results.tsv`. Strategy adapts to the iteration count. Early runs focus on obvious fixes, runs 6 to 15 test single parameters, and later steps explore structural algorithm rewrites.

Execution stays constrained. The agent modifies only the target file defined in config. Introducing new dependencies is forbidden. Ground truth evaluation scripts like `evaluate.py` remain locked from editing.

After editing, the skill commits the change and calls `run_experiment.py --single`. If metrics improve, the change stays; otherwise, it reverts. Every 10 iterations, it updates the strategy section in `program.md`. Missing `.autoresearch` directory files will break the run.

## Install

### Claude Code (native platform)

1. **Plugin marketplace**
In the agent chat (not a shell):
```text
/plugin marketplace add alirezarezvani/claude-skills
```
In the agent chat (not a shell):
```text
/plugin install autoresearch-agent@claude-code-skills
```
This installs the whole autoresearch-agent plugin with all its skills

2. **Skills CLI (Vercel)**
```bash
npx skills add alirezarezvani/claude-skills --skill ar-run -a claude-code
```

3. **Manually: put the files in place**
- File: `~/.claude/skills/ar-run/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/ar-run/

### Codex

**Manually: put the files in place**
- File: `.agents/skills/ar-run/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

**Manually: put the files in place**
- File: `.cursor/skills/ar-run/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install alirezarezvani/claude-skills ar-run
```

2. **Manually: put the files in place**
- File: `.github/skills/ar-run/SKILL.md`

### Gemini CLI

**Platform CLI**
```bash
gemini skills install https://github.com/alirezarezvani/claude-skills --path engineering/autoresearch-agent/skills/ar-run
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/ar-run/SKILL.md` — The legacy .windsurf/skills/ path still works

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/alirezarezvani/claude-skills/tree/HEAD/engineering/autoresearch-agent/skills/ar-run/SKILL.md

## When to use it
- run a single metric-driven code optimization step
- test an isolated code hypothesis without manual commits
- escalate experimentation strategy based on `results.tsv` history
- revert regression changes automatically upon evaluation failure

## Example prompts
- /ar:ar-run engineering/api-speed
- /ar:ar-run
- Run one experiment iteration using /ar:ar-run

name: "ar-run"

# /ar:ar-run — Single Experiment Iteration

Run exactly ONE experiment iteration: review history, decide a change, edit, commit, evaluate.

## Usage

```
/ar:ar-run engineering/api-speed              # Run one iteration
/ar:ar-run                                     # List experiments, let user pick
```

## What It Does

### Step 1: Resolve experiment

If no experiment specified, run `python {skill_path}/scripts/setup_experiment.py --list` and ask the user to pick.

### Step 2: Load context

```bash
# Read experiment config
cat .autoresearch/{domain}/{name}/config.cfg

# Read strategy and constraints
cat .autoresearch/{domain}/{name}/program.md

# Read experiment history
cat .autoresearch/{domain}/{name}/results.tsv

# Checkout the experiment branch
git checkout autoresearch/{domain}/{name}
```

### Step 3: Decide what to try

Review results.tsv:
- What changes were kept? What pattern do they share?
- What was discarded? Avoid repeating those approaches.
- What crashed? Understand why.
- How many runs so far? (Escalate strategy accordingly)

**Strategy escalation:**
- Runs 1-5: Low-hanging fruit (obvious improvements)
- Runs 6-15: Systematic exploration (vary one parameter)
- Runs 16-30: Structural changes (algorithm swaps)
- Runs 30+: Radical experiments (completely different approaches)

### Step 4: Make ONE change

Edit only the target file specified in config.cfg. Change one thing. Keep it simple.

### Step 5: Commit and evaluate

```bash
git add {target}
git commit -m "experiment: {short description of what changed}"

python {skill_path}/scripts/run_experiment.py \
  --experiment {domain}/{name} --single
```

### Step 6: Report result

Read the script output. Tell the user:
- **KEEP**: "Improvement! {metric}: {value} ({delta} from previous best)"
- **DISCARD**: "No improvement. {metric}: {value} vs best {best}. Reverted."
- **CRASH**: "Evaluation failed: {reason}. Reverted."

### Step 7: Self-improvement check

After every 10th experiment (check results.tsv line count), update the Strategy section of program.md with patterns learned.

## Rules

- ONE change per iteration. Don't change 5 things at once.
- NEVER modify the evaluator (evaluate.py). It's ground truth.
- Simplicity wins. Equal performance with simpler code is an improvement.
- No new dependencies.
