Critique, improve, and create Codex skills against one standard: a skill is a correction you got tired of making. Target the step that fails, use leading words that recruit training priors instead of coined terms, keep skills small and user-invoked, grow them only from observed corrections, and delete every instruction that does no work. critique reports findings with fixes and edits nothing; improve prunes no-ops, swaps explanation for leading words, and folds recurring corrections from session history in as one-sentence fixes; create mines session history for repeated corrections, checks overlap and default behavior before writing, and drafts a minimal skill. Subcommands: critique, improve, create.
Rewrite an existing skill to the betterskills standard — prune no-ops, swap explanation for leading words, fold in observed corrections as one-sentence fixes.
