Workflow

1. Detect target prompt/skill file.
2. Compute next version (semver: patch = wording, minor = behavior, major = breaking).
3. Run eval against prior version baseline.
4. Append entry to prompts/CHANGELOG.md:

## [1.2.0] — 2026-05-18
**File**: skills/eval-first/SKILL.md
**Change**: added category coverage demand
**Eval**: 0.87 → 0.91 (+0.04)
**Tokens**: 410 → 480
**Breaking**: no

5. Tag git: prompt/<name>-v1.2.0.

Rules

• No version bump without eval result.
• Major version requires migration note for downstream agents.
• Keep prior version archived: prompts/_archive/<name>-v1.1.0.md.

Companion

eval-first, regression-eval.
