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 | $0.00060 | $0.00401 |
| Opus 5 | $0.00030 | $0.00200 |
| Sonnet 5 | $0.00012 | $0.00080 |
| Haiku 4.5 | $0.00006 | $0.00040 |
Grade A, and why
rust-explain 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 yesterday.
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.

Example Questions
"Why clippy instead of an external linter?" → Dimension 2. Clippy is deeply integrated with the compiler, covering style, correctness, performance, complexity. No external tool matches its coverage.
"What's the coverage threshold?" → Dimension 1. 75% default; 60% new; 85% library.
"Why cargo-deny over cargo-vet?" → Dimension 4. cargo-deny covers advisories + licenses + duplicates + bans in one config file.
"Why is unsafe_code forbidden by default?" → Dimension 3. Most crates don't need unsafe. FFI/interop crates relax this.
"How does WASM support work?" → WASM-Specific Considerations section. Detection, testing, CI, and quality gate adaptations.
"How do I disable a check?" → Each check has a [check:*] comment marker. Delete the run_check block.
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.

rust-explain is a skill published in the GitHub repository ondrasek/cc-plugins (2 stars, last pushed 4mo ago), licensed Apache-2.0. It adds 60 tokens to every session and 401 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
