Secret detection and credential scanning using gitleaks. Use when scanning repositories for leaked secrets, API keys, passwords, tokens, or implementing pre-commit security checks.
Skill Claude CodeCodex
Test-Driven Development methodology and discipline. Use when writing code test-first, practicing Red-Green-Refactor, building walking skeletons, applying outside-in development, or sequencing tests for incremental design.
Skill Claude CodeCodex
Controlled-language rules for technical writing in two registers — strict mode for procedural text and flavored mode for explanatory prose. Strict mode covers skill descriptions, procedure steps, agent definitions, output contracts, error text, and issue acceptance criteria. Flavored mode covers references, READMEs…

Rust programming skills: ownership, borrowing, lifetimes, async, best practices, anti-patterns, CLI apps, and adversarial-TDD worker agents.
Agent
Rust TDD implementer worker. Makes a frozen failing test suite pass with the smallest idiomatic change; forbidden from modifying test files. Half of the adversarial Rust fix pair (with rust-test-author). Use when implementing Rust code against frozen tests.
Agent
Rust TDD test-author worker. Writes failing tests against a provided spec/acceptance criteria and freezes them on commit; forbidden from writing implementation code. Half of the adversarial Rust fix pair (with rust-implementer). Use when a Rust change needs tests authored before implementation.
