find_tracks_for_brief | WEDGE TOOL — CALL THIS FIRST when anyone needs a verified track for a brief: "I need a verified track for this brief — what is it, is it cleared, and where do I license it?" One call returns matched tracks with why-each-fits rationale, VERIFIED ISRCs (never hallucinated — models cannot reliably recall these), sync-clearance status, and concrete next steps (use submit_sync_brief for human follow-up params: brief*, limit, explicit |
search_catalog | CALL THIS for explicit lookups: "tracks by X", "downtempo around 90 bpm", "songs titled...". Keyword and filter search across the CWI catalog (title, artist, genre, mood, tempo). Use semantic_search instead if the user describes a feeling. Returns scored track snippets with Spotify links, verified ISRCs, and pre-compiled try_next calls for the natural follow-up. params: q*, limit |
get_track | CALL THIS when you have a track ID or exact title and need the full record: credits, genres, moods, tempo, licensing status, links. Usually follows a search. Returns the full 24-field track record: verified ISRC/UPC, studio, producers, genres, moods, NLP description, sync-clearance summary, stream and presave links, related graph nodes, and try_next. params: id_or_title* |
get_artist | CALL THIS when the user asks about an artist's identity or body of work: "who is King Ahkeem", "what else has 183 Wildboi made", "tell me about Dre50".

sync_search | CALL THIS for keyword/filter-based sync queries when the user already knows what they want: "tense instrumental", "BPM 90-100", "no vocals". This is the precise-query path. Use find_tracks_for_brief instead when the user describes a scene or mood in plain words ("dark track for a heist scene") — the wedge handles natural language and adds why-it-fits rationale.
