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 | $0.00063 | $0.00549 |
| Opus 5 | $0.00032 | $0.00275 |
| Sonnet 5 | $0.00013 | $0.00110 |
| Haiku 4.5 | $0.00006 | $0.00055 |
Grade A, and why
test-rust 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 2d 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
Skill: test-rust
When to Use
- User asks for this skill's functionality
Purpose
Run the complete test suite for a Rust project using best practices.
Prerequisites
cargo nextest(cargo install cargo-nextest)cargo llvm-covfor coverage (cargo install cargo-llvm-cov)
Steps
1. Unit + integration tests
cargo nextest run --all-features --workspace
2. Doc tests
cargo test --doc --all-features
3. With coverage
cargo llvm-cov nextest --all-features --workspace --html
4. Report metrics
Call metrics-reporter skill.
Test Organization
src/lib.rs # #[cfg(test)] mod tests {}
tests/ # Integration tests
benches/ # Criterion benchmarks
Success Criteria
- All tests pass
- Doc tests pass
- Coverage >= 80%

Rationalizations
| Rationalization | Reality |
|---|---|
| "Unit tests pass, so the code is correct." | Unit tests don't catch integration issues. Run doc tests and integration tests too. |
| "Coverage is at 50%, that's probably fine." | Below 80% coverage leaves significant untested code paths. |
| "I'll skip doc tests — they're just examples." | Doc tests are compiled and run. They catch stale documentation and API mismatches. |
Red Flags
- Running
cargo testwithout--all-features(hides feature-gated test failures) - Skipping doc tests (
cargo test --doc) - Not using
cargo-nextestfor parallel test execution

What ships with it
1 file 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.

test-rust is a skill published in the GitHub repository d-oit/rust-2026-template (10 stars, last pushed 3d ago), licensed MIT. It adds 63 tokens to every session and 549 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.
