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 | $0.00066 | $0.00254 |
| Opus 5 | $0.00033 | $0.00127 |
| Sonnet 5 | $0.00013 | $0.00051 |
| Haiku 4.5 | $0.00007 | $0.00025 |
Grade A, and why
accessible-media-authoring 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 11d 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.
What it actually says
Accessible Media Authoring
Author alt-text, captions, and transcripts for generated or third-party media to accessibility standards.
Steps
- Perceive the asset (multimodal ingest); if it can't be perceived, request it or report
capability_gap— never invent content. - Write alt-text that conveys function/meaning, not a literal pixel description; keep decorative assets marked decorative.
- Author captions with timing, speaker labels, and non-speech sound cues.
- Author a complete transcript covering all spoken and meaningful non-speech audio.
- Verify each artifact against the source asset.
Acceptance
- Missing alt-text/captions/transcript is a PASS-blocker, not a warning.
- Captions are timed and complete; transcript covers all audio.
- No transcript/alt content invented for media that could not be perceived.
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.

accessible-media-authoring is a skill published in the GitHub repository mtarcure/claude-vibe-squad (148 stars, last pushed 2d ago), licensed MIT. It adds 66 tokens to every session and 254 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings.
