agentille-claude-md — CLAUDE.md tune-up

Opinionated trim, never a silent overwrite. Runs locally: reads one file, writes that file plus a .bak, sends nothing anywhere. Runs only when typed (disable-model-invocation).

Steps

1. Target. No argument → ~/.claude/CLAUDE.md; otherwise the given path. If the file does not exist, say "No CLAUDE.md at <target> — nothing to tune" and STOP; create nothing. Otherwise read it and count its lines.
2. Rewrite in memory. Apply rubric.md to produce a leaner REWRITE. Identity and personal context (rubric point 7) stay verbatim. Tag every removed or merged line with a reason tag from the rubric.
3. Present: the full REWRITE, the cut-list (one line per removed or merged original line with its tag), and before <N> → after <M>. Then ask: "Apply this rewrite to <target>? (yes / no)".
4. On yes: cp <target> <target>.bak (if the .bak exists, ask before overwriting it; on no, stop without writing), then write REWRITE to <target>. Print Tuned <target> — N → M lines. Backup: <target>.bak. On no: write nothing and print No changes written.

Hard rules

• Never write without explicit approval; diff first.
• Always back up first; never overwrite a .bak unasked.
• Never create a file; if the target is absent, stop.
• Never anonymize or strip the user's name, role, stack or genuine constraints.
• Never add a rule the original did not state: a rewrite merges and shortens, it does not invent.

Example (generic)

Before (4 lines): I am a developer and would like you to be concise. / Use TypeScript for this Vite app. / Be helpful and write good clean code. / Use TypeScript.

After (2 lines): - Developer; be concise. / - TypeScript.

Cut-list: "Vite app" → inferable; "Be helpful…" → vague; "Use TypeScript." → duplicate.
