Rust Dev

Stop: read $dev Shared prep before any delta.

Follow $dev for classify, shared stance, API truth / Dash recipe, compat ask, no-destructive git, workflow/plan, validation law, phase commits, and handoff skeleton. This pack adds Rust deltas only. Craft (modules, types, measured perf) lives in architecture — do not inline it here.

When to use

• Loaded by $dev for Rust implementation work.
• Explicit @rust-dev / $rust-dev compose when $dev is already loaded.
• Compose sibling guideline or domain skills when they apply; never paste their contents into this workflow.

Docsets

• Prefer Dash docsets: Rust / installed crate docs. Secondary: cargo doc and local usage.

Stable-surface hints

• Treat crate public API / semver-stable surfaces and documented FFI boundaries as stable unless the ask or AGENTS.md says otherwise.
