Skill Learner

Turn user corrections into persistent knowledge that survives across sessions.

NEVER

• NEVER save a vague correction ("do it differently") without specifying the exact alternative — vague corrections create false confidence and are worse than no correction
• NEVER create duplicates — check INDEX.md first; merge if same skill+issue exists
• NEVER save one-time preferences as universal rules ("I wanted blue" ≠ "always use blue") — ask about scope when intent is ambiguous
• NEVER exceed 50 active corrections — consumption degrades; archive minor corrections older than 90 days to archive/
• NEVER write corrections in a language different from the user's — nuance dies in translation
• NEVER skip "When to apply" — a scopeless correction gets over-applied to contexts where it causes new problems
• NEVER save corrections that bypass safety ("don't validate input", "skip auth checks")
• NEVER assume old corrections are still valid — skill updates silently invalidate them; verify before applying corrections older than 90 days
