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 | $0.00221 | $0.02431 |
| Opus 5.5 | $0.00088 | $0.00972 |
| Sonnet 5.5 | $0.00044 | $0.00486 |
| Haiku 4.5 | $0.00022 | $0.00243 |
Grade E, and why
configuring-project-permissions scanned grade E with 3 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 23d 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.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

No licence file
A repository with no LICENSE is all rights reserved by default, so the body is not copied here. The metadata, the measurements and the link are.
What ships with it

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.

configuring-project-permissions is a skill published in the GitHub repository tomada1114/tomada-claude-plugins (5 stars, last pushed 3d ago), with no licence file. It adds 221 tokens to every session and 2,431 once invoked, about $0.0009 per session on Opus 5.5. A static security scan graded it E with 3 findings (hidden instructions, reads agent configuration directories, recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-30.
