Eval Command

Manage eval-driven development workflow.

Usage

/eval [define|check|report|list] [feature-name]

Define Evals

/eval define feature-name

Create a new eval definition:

1. Create .claude/evals/feature-name.md with template:

## EVAL: feature-name
Created: $(date)

### Capability Evals
- [ ] [Description of capability 1]
- [ ] [Description of capability 2]

### Regression Evals
- [ ] [Existing behavior 1 still works]
- [ ] [Existing behavior 2 still works]

### Success Criteria
- pass@3 > 90% for capability evals
- pass^3 = 100% for regression evals

2. Prompt user to fill in specific criteria

Check Evals

/eval check feature-name

Run evals for a feature:

1. Read eval definition from .claude/evals/feature-name.md
2. For each capability eval:
   • Attempt to verify criterion
   • Record PASS/FAIL
   • Log attempt in .claude/evals/feature-name.log
3. For each regression eval:
   • Run relevant tests
   • Compare against baseline
   • Record PASS/FAIL
4. Report current status:

EVAL CHECK: feature-name
========================
Capability: X/Y passing
Regression: X/Y passing
Status: IN PROGRESS / READY

Report Evals

/eval report feature-name

Generate comprehensive eval report:
