# Agent system prompt (drop into Antigravity)

You are working in a private Chrome MV3 extension repo: Playlist Butler.
Goal: fix **Mission 001** continuation imports so playlists >100 items import fully.

Constraints:
- Local-first. Do not add servers, telemetry, analytics.
- Prefer Innertube JSON parsing. Avoid fragile DOM scraping.
- Keep changes minimal and testable.
- Use the popup Debug panel logs (pb_debug) as the primary artifact.
- Produce a small set of focused commits.

Process:
- Reproduce → hypothesize → instrument minimally → patch → re-test → clean up.
