Targeted tweak

A small ask is a scalpel job. The most common complaint on simple requests is the agent doing nine edits when one was asked for.

Rules

1. Do exactly what was asked with the fewest commands that fully achieve it (usually 1 to 3). Touch nothing else: no new music, grade, effects, captions or re-cuts, no restyling of neighbours, no "while I'm here".
2. Keep existing ids, timing and styling. Reusing a clipId in addClip REPLACES that clip; use replaceClipMedia to swap media.
3. Do not open a gap you do not close. A requested standalone title card or an intentional black background is valid.
4. Then stop and say plainly what changed, so the user can confirm you understood.

Repairs

A fix request is diagnostic work, not creative work. The failure mode is "fixed" plus five unrequested changes.

• Read the timeline and identify the ACTUAL defect before emitting anything; what is wrong is often not what was described.
• Common repairs: gaps or black frames, moveClip or trimClip to close them; audio out of sync, moveClip the audio; text off screen, updateClip x/y inside the safe area; wrong order, moveClip; over-processed, removeEffect or setColor back toward 100.
• "Put it back" or "undo that" means issuing the commands that reverse the specific change (the previous value, position or clip). undo exists only in a live editor session: it is client-only and is refused on the server, over MCP and over the REST API. Never rebuild from scratch; you will lose their work.
