Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Excessive Agency · line 4 Skill selects an external model or provider that may use a different account or billing plan than the operator expects. Undisclosed model switches can cause unexpected cost or quota consumption.Fix: Remove the model/provider override or disclose it prominently and require explicit operator approval before invoking an external coding CLI or billed model.
What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00036 | $0.01708 |
| Opus 5 | $0.00018 | $0.00854 |
| Sonnet 5 | $0.00007 | $0.00342 |
| Haiku 4.5 | $0.00004 | $0.00171 |
Grade A, and why
promo-director scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 238 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Promo Director Skill
Generate professional promo videos for social media from mastered audio. Creates 15-second vertical videos (9:16, 1080x1920) optimized for Instagram Reels, Twitter, and TikTok.
Purpose
After mastering audio, generate promotional videos that combine:
- Album artwork
- Audio waveform visualization (9 styles available)
- Track title + artist name
- Automatic color scheme extracted from artwork
- Intelligent segment selection (finds the most energetic 15 seconds)
When to Use
- After mastering complete, before release
- User says "generate promo videos" or "create promo videos for [album]"
- When album has mastered audio + artwork ready
Position in Workflow
Generate → Master → **[Promo Videos]** → Release
Optional step between mastering-engineer and release-director.
Workflow
1. Setup Verification
Check ffmpeg:
ffmpeg -filters | grep showwaves
Required filters: showwaves, showfreqs, drawtext, gblur
If missing:
Error: ffmpeg not found or missing required filters
Install ffmpeg:
macOS: brew install ffmpeg
Linux: apt install ffmpeg
After installing, run this command again.
Check Python dependencies:
Call get_python_command() to verify the venv exists. If venv_exists is false, show the warning and suggest /bitwize-music:setup.
2. Album Detection
Resolve audio path via MCP:
Call resolve_path("audio", album_slug) — returns the full audio directory path including artist folder.
Example result: ~/bitwize-music/audio/artists/bitwize/albums/electronic/sample-album/
Verify contents:
- ✓ Mastered audio files (.wav, .mp3, .flac, .m4a)
- ✓ Album artwork (album.png or album.jpg)
If artwork missing:
Error: No album artwork found in {audio_root}/artists/{artist}/albums/{genre}/{album}/
Expected: album.png or album.jpg
Options:
1. Use /bitwize-music:import-art to place artwork
2. Specify path manually: --artwork /path/to/art.png

What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
