# /ar:run — Single Experiment Iteration

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

## Usage

```
/ar:run engineering/api-speed              # Run one iteration
/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.

## Diff History
- **v00.33.0**: Ingested from claude-skills-main
