Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| create_projectA | Start a new faceless video project. format 'shorts' = 1080x1920 vertical (<60s), 'long' = 1920x1080. Returns the project id used by all other tools, plus the quality guide you should follow when writing the script. |
| set_scriptA | Set (or replace) the full scene list: per scene one narration passage and one image prompt. You are the writer — bring a hook, concrete details, and one idea per scene. Returns pacing/quality warnings; fix them before generating assets. |
| generate_narrationA | Synthesize narration audio for every scene (or the listed sceneIds) with voicebox TTS. Returns per-scene durations. |
| generate_imagesB | Generate one image per scene (or the listed sceneIds) with CodexImage, at the project aspect ratio. The project imageStyle is appended to every prompt for visual consistency. |
| generate_captionsA | Build burned-in captions from the narration audio. Uses whisper word timestamps when available (mlx_whisper or whisper CLI), otherwise proportional timing. Shorts get karaoke word-highlight. Run after generate_narration. |
| assemble_videoA | Render the final video: Ken Burns motion per scene (alternating direction), concat, optional caption burn-in, optional background music (looped, ducked), loudness-normalized to -14 LUFS. Returns the output path. |
| list_voicesA | List available voicebox voice profiles (name + id) so you can pick a fitting narrator. |
| generate_thumbnailA | Generate a text-free thumbnail image via CodexImage (1536x1024 landscape for long-form, 1024x1536 for shorts). Prompt one dramatic subject with strong lighting — add title text later in an editor. |
| project_status | Show a project's pipeline state: which scenes have narration/images, captions, output. |

Scored across 8 tools
Each tool has a distinct, non-overlapping purpose, covering the entire video creation pipeline. There is no ambiguity about which tool to use for a given task.
All tool names follow a consistent verb_noun pattern (e.g., create_project, set_script, generate_narration), making them predictable and easy to understand.
With 8 tools, the set is well-scoped for a faceless video creation workflow. Each tool serves a necessary step without being too few or too many.
The tools cover the core workflow (create project, script, generate assets, assemble, thumbnail) but lack scene-level editing or project management features, which are minor gaps.
