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 | $0.00091 | $0.01700 |
| Opus 5 | $0.00046 | $0.00850 |
| Sonnet 5 | $0.00018 | $0.00340 |
| Haiku 4.5 | $0.00009 | $0.00170 |
Grade C, and why
mk:multimodal scanned grade C 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 4d 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.
Hidden instructionshighPrompt injection
Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

The opening of the file, as written. The whole thing — 151 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Multimodal Analysis & Generation
Path convention: Commands below assume cwd is
$CLAUDE_PROJECT_DIR(project root). Prefix paths with"$CLAUDE_PROJECT_DIR/"when invoking from subdirectories.
Model selection and commands
Use the configured analysis default for media understanding. Generation routes Gemini → MiniMax → OpenRouter as keys permit. Provider model IDs, preview availability, and pricing change frequently: load references/models-and-pricing.md at execution time and verify preview IDs against the provider dashboard before relying on one.

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.

mk:multimodal is a skill published in the GitHub repository ngocsangyem/MeowKit (14 stars, last pushed 1mo ago), licensed MIT. It adds 91 tokens to every session and 1,700 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it C with 1 finding (hidden instructions). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
