SkillSpector: 6 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00030 | $0.04644 |
| Opus 5 | $0.00015 | $0.02322 |
| Sonnet 5 | $0.00006 | $0.00929 |
| Haiku 4.5 | $0.00003 | $0.00464 |
Grade A, and why
axum-idioms 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 13d 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.

Axum Idioms and Patterns
Core Philosophy
Axum (0.8+) rewards composability via Tower, type-safe extractors, and zero-cost abstractions. Idiomatic Axum = thin handlers, tower middleware, typed errors.
Version note: This skill targets Axum 0.8+ (released 2025). Key changes from 0.7: path parameter syntax changed from
:nameto{name},Stateextractor is now inaxum::extract, andaxum::servereplacesaxum::Server. If you encounter an existing codebase on 0.7, check the Axum 0.8 changelog before applying these patterns.
Scope: Axum-specific patterns. For Rust fundamentals: @.agents/skills/rust-idioms/SKILL.md. For project structure: @.agents/skills/rust-idioms/references/project-structure.md.
Router and Route Organization
-
Build routers with
Router::new()and method routing:// ✅ Group by resource, nest for versioning fn task_routes() -> Router<AppState> { Router::new() .route("/tasks", get(list_tasks).post(create_task)) .route("/tasks/{id}", get(get_task).put(update_task).delete(delete_task)) } fn app(state: Arc<AppState>) -> Router { let api = Router::new() .merge(task_routes()) // .merge() combines peer routers .merge(user_routes()); Router::new() .nest("/api/v1", api) // .nest() adds prefix to sub-router .fallback(handle_404) // typed error, not Axum's default plain-text 404 .with_state(state) } -
Path parameters use
{name}syntax (not:name).
Extractors
- Built-in extractors —
Path,Query,Json,State,HeaderMap:// ✅ Typed and validated at compile time async fn get_task( State(state): State<Arc<AppState>>, Path(id): Path<Uuid>, ) -> Result<Json<TaskResponse>, AppError> { let task = state.task_service.find(id).await?; Ok(Json(task.into())) }
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.

axum-idioms is a skill published in the GitHub repository irahardianto/awesome-agv (156 stars, last pushed 22d ago), licensed MIT. It adds 30 tokens to every session and 4,644 once invoked, about $0.0002 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 2026-08-30.
