Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| rememberA | Add a YouTube video or podcast episode to the second brain. Pass a YouTube URL, or a podcast RSS feed URL (optionally with an
|
| recallA | 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. |
| libraryC | List everything stored in the second brain, newest first. |
| transcriptA | Read the raw transcript of one item (by id, URL, or title fragment). Optionally slice by |
| digestA | Summarize what was added to the brain in the last N days. |
| forgetA | 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. |

Scored across 6 tools
Each tool serves a unique function: remember adds content, recall searches, library lists, transcript retrieves raw text, digest summarizes recent additions, and forget deletes. No two tools overlap in purpose, and their descriptions clarify the distinct use cases.
Most tool names are single-word imperative verbs (remember, recall, digest, forget), giving a clear action-oriented pattern. However, 'library' and 'transcript' are nouns, breaking the otherwise consistent verb style, though still predictable in context.
With six tools, the set is well-scoped for a personal knowledge management server. Each tool addresses a core need—adding, searching, listing, reading, summarizing, and deleting—without unnecessary bloat or overlap.
The tool surface covers the full lifecycle for stored media: creation (remember), retrieval (recall, library, transcript), summarization (digest), and deletion (forget). There are no obvious gaps or dead ends; the only potential missing operation is update, but it's not essential for this domain.
