skills_loader.rs walks skills/**/*.md, parses YAML frontmatter
(name, description, when_to_use, tags), upserts via
skills_catalog::upsert_builtin. Idempotent per boot — bumps version
+ appends skill_versions row ONLY when body changes. Deterministic
sha256-derived ids so builtins are stable across boots.
Dockerfile copies skills/ to /etc/clawmates/skills. Server boot
task spawns loader alongside team_template_loader.
Follow-ups (Slice 3.5c continuation, future PRs):
- 20-30 more skills (duckdb, shadcn composition, a11y, WebGPU
migration, metal frame capture, rocprof, deep gitea forge
integration, semgrep rulepacks)
- Bind skills to team template roles (add [role.skills] refs to
templates/teams/*.toml + wire template_role_skills population
in team_template_loader)

Writing Rust (edition 2024, MSRV 1.97.1)
Toolchain we ship against
Version fields as of 2026-07. Verify with rustc --version before assuming.
- stable: 1.97.1
- workspace MSRV: 1.97.1 (some crates require 1.98.0+; check
rust-toolchain.toml) - edition: 2024 (default for new crates; workspace-wide bump per project)
- cargo tools we standardize on:
cargo-nextest 0.9.140,cargo-audit 0.21+,cargo-llvm-cov 0.6+,cargo-machete,cargo-hakari(for workspace unification)
Idioms
let-elseover deep nesting.let Some(user) = auth.load(id).await? else { return Err(NotFound.into()); };?with.context()at every boundary (usesanyhow::Contextor the equivalent). Bare?inside a private function is fine; at API surfaces, add context.if letchains (stable in edition 2024):Nest withif let Some(x) = maybe && x > 0 && !seen.contains(&x) { ... }if letblocks in edition-2021 crates until MSRV catches up.- Struct-of-args when a fn exceeds ~5 params — pass an
Args<'a>struct. Clippy'stoo_many_argumentsenforces at 7. impl Traitin argument position for callbacks;Box<dyn Trait>only when erasure is genuinely needed.Arc<T>overRc<T>anywhereSendmight matter — you're almost always in a Tokio runtime.
Anti-patterns
unwrap()in library code. Only allowed in tests, inmain.rsbefore the runtime spins up, and behinddebug_assert!..clone()as a borrow-checker escape. Ask why the borrow can't work first. If it genuinely can't, add a comment explaining the tradeoff.Arc<Mutex<T>>when a channel would do. For actor-like state,tokio::sync::mpscis almost always the right answer.Box<Pin<Future>>in public APIs whereimpl Futurewould do — leaks implementation and forces heap alloc.#[allow(clippy::...)]without a comment. Every allow needs a one-line WHY.
Testing
cargo nextest runas the default runner — faster, better output, isolates flaky tests. Fall back tocargo testwhen nextest isn't installed.#[tokio::test]for async. Prefer#[tokio::test(flavor = "multi_thread")]when the code under test spawns.- See cargo-test-driven-development for the TDD flow.
Lint policy
Every Rust crate CI runs cargo clippy --all-targets -- -D warnings. Warnings ARE errors. Fix the warning; if it's a false positive, #[allow(...)] with a comment.
