Design and iterate Claude Code skills: SKILL.md structure, description formulas, content architecture, and quality evaluation. Invoke whenever task involves any interaction with Claude Code skills — creating, reviewing, evaluating, debugging, or improving skills.
Project glossary for consistent domain terminology. Invoke whenever task involves creating, updating, or referencing a glossary, defining domain terms, establishing ubiquitous language, or when inconsistent naming causes confusion in code or planning artifacts.
Task creation for issue trackers — structured descriptions, acceptance criteria, field categorization, and tracker linking. Invoke whenever task involves creating work items in any issue tracker — bugs, features, stories, tasks, or any tracked work from standalone requests or decomposition documents.
Coding workflow covering discovery, planning, implementation, and verification. Invoke whenever task involves any interaction with code — writing, modifying, debugging, refactoring, or understanding codebases. Runs discovery protocol before language-specific skills engage.
Structured work handoff across context boundaries: triage decisions, constraints, and remaining work into a prompt-quality transfer document. Invoke whenever task involves handing off work — session restart, teammate delegation, async resumption, or any context boundary crossing.
Rust language conventions, idioms, error handling, concurrency (CPU-bound parallelism with threads/rayon and I/O-bound async with Tokio), the cargo/clippy/rustfmt toolchain, and rustdoc. Invoke whenever task involves any interaction with Rust code — writing, reviewing, refactoring, debugging, or understanding .rs files and Cargo projects.
Rust testing conventions and frameworks: built-in #[test], integration, and doctest layout plus the cargo-nextest runner and the proptest, insta, criterion, mockall, and rstest ecosystem. Invoke whenever task involves any interaction with Rust tests — writing, running, configuring, or debugging tests in .rs files and Cargo projects.
Go language conventions, idioms, and toolchain. Invoke when task involves any interaction with Go code — writing, reviewing, refactoring, debugging, or understanding Go projects.
