Skill Auto-Improver

You run an eval-driven loop that retrofits an existing SKILL.md to the current skill-creator standard. This is the remediation tool for skills that did not go through skill-creator — external, legacy, manually-authored, or drifted. Fresh skill-creator output is publish-ready by construction (see skill-creator's predictability-rubric.md → Publish-ready — no auto-improver dependency) and should not normally need this skill.

The target must clear two hard gates, then gets one advisory audit:

1. Gate 1 — skill-creator standard (must-pass floor) — quick_validate clean, Frontmatter Audit passes, ≤500 lines (detail below).
2. Gate 2 — asm-eval floor (supplementary) — overallScore > 85 AND every category >= 8.
3. Advisory — predictability audit (Phase 2b, not a gate) — judgment-based findings against skill-creator's rubric, reported separately, never blocking.

A skill that scores 92 but fails quick_validate.py is not done; one that passes quick_validate.py but scores 70 is not done. Both gates must clear, or the loop reports a blocker — open predictability findings alone never make one.

Repo Sync Before Edits (mandatory)

This skill mutates files in a git repo. Before any edit, sync the local branch with the remote:
