# Diagram Tour

Generate a narrated architecture-tour video from a codebase.

Generate a narrated architecture-tour video from a codebase. End-to-end: codebase analysis → Graphviz .dot → narration script → narrated MP4. Three confirmation gates between user and final video. Use when the user asks to "explain this codebase", "tour the architecture", "make a video about how X works", or invokes /diagram-tour explicitly. Output: a versioned MP4 at <project>/.diagram-tour/renders/. Expensive — confirm runtime expectations (~15-30 min on modern hardware, longer on lighter machines) before kicking off.

- Runs in: Claude Code
- Output: MP4, Audio (MP3 / WAV)
- Generates with: Your agent's own model
- v2026.4.28 · by centraltowerlabs
