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.

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 | $0.00123 | $0.02155 |
| Opus 5 | $0.00062 | $0.01077 |
| Sonnet 5 | $0.00025 | $0.00431 |
| Haiku 4.5 | $0.00012 | $0.00215 |
Grade B, and why
blog-audio scanned grade B with 1 finding 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 9d 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.

95% identical to blog-audio — 22 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Blog Audio: Gemini TTS Narration for Blog Posts
Generate professional audio narration of blog content using Google's Gemini TTS. Three modes: summary (200-300 word spoken overview), full article read-aloud, or two-speaker podcast dialogue. 30 voices, 80+ languages, HTML5 embed output.
Quick Reference
| Command | What it does |
|---|---|
/blog audio generate <file> |
Generate audio narration of a blog post |
/blog audio voices |
Show available voices with characteristics |
/blog audio setup |
Check/configure API key for Gemini TTS |
Prerequisites
- Python 3.11+ (venv managed automatically by
run.py) GOOGLE_AI_API_KEYenvironment variable (same key used by blog-image)- FFmpeg (for WAV-to-MP3 conversion; falls back to WAV if missing)
Always Use run.py Wrapper
# CORRECT:
python3 scripts/run.py generate_audio.py --text "..." --voice Charon --json
# WRONG:
python3 scripts/generate_audio.py --text "..." # Fails without venv
API Key Check (Gate Pattern)
Before generating audio, check for the API key:
echo $GOOGLE_AI_API_KEY
- If set: proceed with generation
- If not set: guide the user:
"Audio generation requires a Google AI API key. Get one free at https://aistudio.google.com/apikey
Then set it:
export GOOGLE_AI_API_KEY=your-keyThis is the same key used by/blog image: if image generation works, audio works too." - When called internally (from blog-write): return silently if key is missing. Never block the writing workflow.
Setup
For /blog audio setup:
- Check if
GOOGLE_AI_API_KEYis set in environment - If blog-image is configured (check
.mcp.json), the key is already available - If not, guide user to https://aistudio.google.com/apikey
- Verify with a dry run:
python3 scripts/run.py generate_audio.py --text "Test" --dry-run --json
Voice Selection
For /blog audio voices:
Load references/voices.md and present the voice catalog to the user.
Ask the user which voice they prefer, or recommend based on content type:
- Article narration: Charon (Informative) or Sadaltager (Knowledgeable)
- Tutorial/how-to: Achird (Friendly) or Sulafat (Warm)
- News/analysis: Rasalgethi (Informative) or Schedar (Even)
- Lifestyle/wellness: Aoede (Breezy) or Vindemiatrix (Gentle)
- Dialogue host: Puck (Upbeat) or Laomedeia (Upbeat)
- Dialogue expert: Kore (Firm) or Charon (Informative)
What ships with it
7 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.

blog-audio is a skill published in the GitHub repository Infrasity-Labs/dev-gtm-claude-skills (124 stars, last pushed 2mo ago), licensed MIT. It adds 123 tokens to every session and 2,155 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root).
