Commands

What you get

/evaluate
Score any prompt 1–5 across five dimensions. See the top 3 issues with copy-paste fixes. Shows previous score if one exists.
/improve
Paste a rough prompt, get a polished version with schemas, guardrails, and zero filler. Auto-suggests splitting into phases when the result is too complex.
/regression
Compare old vs new. See what improved, what regressed, and whether it's safe to ship. Validates against your golden dataset.
/test
Run your prompt against every golden test case. See pass/fail results, failure patterns, and suggested fixes.
/compare
Benchmark across Opus, Sonnet, Haiku, GPT-4o. Per-run cost, daily cost, routing rules. Supports custom pricing via config.
/run
Execute the winning prompt for real. Delivers actual output, not another evaluation. Works across sessions.

Prompt Evaluation — 1.8/5.0
Structure 2/5 · Specificity 2/5 · Output Control 1/5
Error Prevention 1/5 · Testability 2/5

1. [Output Control] No format specified. Fix: add JSON schema
2. [Error Prevention] No guardrails. Fix: add "Do NOT" patterns
3. [Specificity] Too vague. Fix: add role framing + constraints
