skill-review (the promote gate)

skill-curator's background reviewer stages skill drafts under ~/.claude/skill-proposals/. It
NEVER writes ~/.claude/skills/. This skill is the human gate that promotes a vetted draft into the
live library. bin/skill-review (from lib/skill-curator/, put it on PATH or invoke by its full
path) is the only writer of ~/.claude/skills/.

Flow

1. List the staged drafts:

   skill-review list      # tab-separated: <slug>\t<description>

   If "(no staged drafts)", stop and say so.

2. For each draft, read ~/.claude/skill-proposals/<slug>/SKILL.md and vet it. Run the
   superpowers:writing-skills checklist (this skill does NOT reimplement it , delegate):

   • Is the name class-level (not a PR number, error string, codename, or today-only artifact)?
   • Is the description a real trigger (what class of task + when), so a future agent matches it?
   • Is it a genuine reusable pattern, or environment-dependent / a complaint that will rot into a
     refusal? Drop the latter.
   • Secret scan: confirm no token / key / credential is in the body. promote also refuses a
     draft that still contains one, but check first.
   • Would this be better as a PATCH to an existing umbrella, or a references/ add, than a new
     skill? If so, reject and patch by hand.

3. Decide per draft (always show the user the draft and your read before acting):

   • Approve -> skill-review promote <slug> (moves it into ~/.claude/skills/<slug>/; refuses to
     overwrite a live skill without --force).
   • Reject -> skill-review reject <slug> (moves it to _rejected/, recoverable, never deleted).

4. Report what was promoted vs rejected, and any draft you left staged for the user to decide.

Rules

• Never promote a draft you have not read and vetted against writing-skills.
• Never --force overwrite a live skill without explicitly confirming with the user first.
• Promotion is the ONLY path a draft enters ~/.claude/skills/. The reviewer cannot (it runs with
  no write tool). Keep it that way.
• An optional auto_promote config knob (default OFF) can auto-pass the lowest-risk class only
  (a references/ add to an existing umbrella) via skill-review auto; everything else is manual.
