Conductor MCP

Hosted thiri-mcp adds conduct_band (HTTP). Local thiri-conductor-mcp renders WAV via Csound CLI using shared @thiri/csound-core.

Flagship agent recipe

Copy-paste prompt chain: analyze → conduct → render → critique. Full steps with dual MCP config on /lab/agent-recipes.

Step 1 (thiri): analyze_chord each chord in Dm7 G7 Cmaj7, key C.
Step 2 (thiri): conduct_band — "warm Rhodes, walking bass, brush drums, 8 bars medium swing in C."
Step 3 (thiri-conductor): build_csound_score → render_csound_wav.
Step 4: critique voice-leading; play_audio; suggest one revision.
