Skill: evolve-check

Trigger: "evolve check", "check evolve", "which skills need evolving", "evolve status", "skill health"

Description: Reads skill_scores.md and surfaces which skills are ready for /evolve. Analysis only — no patching, no file changes.

Allowed Tools: Read, Glob

Steps

1. Read tasks/skill_scores.md — load all data rows. If the table is empty, report: "No skill scores logged yet. Run /learn at the end of sessions to populate skill_scores.md." Then stop.

2. Group by skill name. For each skill compute:

   • Total fires (all rows for this skill)
   • Unpatched Y count — Y rows where Skill Patched = - (not yet fixed by /evolve)
   • Patched Y count — Y rows where Skill Patched != - (already fixed by /evolve)
   • N count (Correction Needed = N)
   • Consecutive unpatched Y streak — count from the most recent row backwards until an N or a patched-Y is hit
   • Whether any unpatched Y entries have "INSUFFICIENT DATA" or vague "What Failed" (no step number)

   Important: Only unpatched Y entries (Skill Patched = -) count toward URGENT/WATCH thresholds. Patched entries are resolved — they don't count as open failures.

3. Classify each skill:
   • 🔴 URGENT — 3+ unpatched Y scores, OR 2+ consecutive unpatched Y scores on the same step
   • 🟡 WATCH — exactly 2 unpatched Y scores (threshold met, ready for /evolve)
   • 🔵 PATCHED — has Y entries but ALL have Skill Patched != -; skill was fixed but not yet confirmed stable
   • 🟢 STABLE — 0 or 1 unpatched Y score, or 10+ consecutive N scores (includes post-patch N scores)
   • ⚠️ DATA MISSING — has unpatched Y entries but "What Failed" is vague or marked INSUFFICIENT DATA

4. Output the report:

   === Evolve Check ===
   
   🔴 URGENT — patch now
     [skill] — [unpatched Y count] open failures, [streak] consecutive on Step [N]
     Latest failure: "[verbatim What Failed entry]"
   
   🟡 WATCH — ready for /evolve
     [skill] — 2 open Y entries ([dates])
     Failures: Step [N] / Step [N]
   
   🔵 PATCHED — awaiting confirmation
     [skill] — all Y entries patched on [date], [N] uses since patch
     Next N score → promote to 🟢 STABLE
   
   🟢 STABLE
     [skill] — [N count] clean sessions
   
   ⚠️ DATA MISSING — cannot evolve yet
     [skill] — Y logged but "What Failed" too vague to patch
     Action: next failure, log as: Step [N]: produced [X], needed [Y]. Fixed by [Z].
   
   ---
   [N] skills flagged (🔴/🟡 only — 🔵 PATCHED are resolved pending confirmation).
   Run /evolve on flagged skills now? [y/N]

5. Check tasks/skill_usage.md for stale skills: Read the Last Used column. For any skill where Last Used date is more than 10 sessions ago OR shows "unknown":

   "[skill] hasn't been used in 10+ sessions. Options: a) Keep — schedule it for next relevant session b) Deprecate — delete SKILL.md and remove from skill_usage.md c) Skip for now"

   If user picks b: delete the skill file and remove its row from skill_usage.md. Do NOT silently leave stale skills — unused skills add noise to the system prompt and confuse trigger matching.

6. Stop. Do not patch anything else. Do not modify any files beyond what the user explicitly confirms above.

Notes

• This is a read-only diagnostic — it surfaces signals, never acts on them
• Run at End Session to catch urgent skills before the session closes
• /evolve does the actual patching — this just tells you when to run it
• A skill with alternating Y/N is not stable — the previous fix didn't hold; flag it manually
