eval

name	eval
description	Manage eval-driven development workflow with define, check, report, and list commands. Use when user says "define eval", "check evals", "eval report", or "list evals". Tracks pass@k metrics for capability and regression evals.

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:

EVAL REPORT: feature-name
=========================
Generated: $(date)

CAPABILITY EVALS
----------------
[eval-1]: PASS (pass@1)
[eval-2]: PASS (pass@2) - required retry
[eval-3]: FAIL - see notes

REGRESSION EVALS
----------------
[test-1]: PASS
[test-2]: PASS
[test-3]: PASS

METRICS
-------
Capability pass@1: 67%
Capability pass@3: 100%
Regression pass^3: 100%

NOTES
-----
[Any issues, edge cases, or observations]

RECOMMENDATION
--------------
[SHIP / NEEDS WORK / BLOCKED]

List Evals

/eval list

Show all eval definitions:

EVAL DEFINITIONS
================
feature-auth      [3/5 passing] IN PROGRESS
feature-search    [5/5 passing] READY
feature-export    [0/4 passing] NOT STARTED
