Add a YouTube video or podcast episode to the second brain.

Pass a YouTube URL, or a podcast RSS feed URL (optionally with an episode title filter; defaults to the latest episode). The transcript is fetched, chunked with timestamps, and indexed for search. Returns the stored item's id — use it with transcript and forget.

Search everything ever watched or listened to.

Full-text (BM25) search across all indexed transcripts. Returns the most relevant passages with timestamps and deep links so the exact moment can be replayed. Use this to answer questions like "what did that video say about X?" — then answer from the returned passages, citing timestamps.

List everything stored in the second brain, newest first.

Read the raw transcript of one item (by id, URL, or title fragment).

Optionally slice by start/end seconds to pull just one section.

Summarize what was added to the brain in the last N days.

Permanently delete an item (by id, URL, or title fragment).

Requires explicit user confirmation via the MRTR elicitation flow — nothing is deleted until the user approves.
