What's Inside
Agents5
code-reviewer
/code-reviewer
Use proactively when a logical chunk of implementation is complete and needs review against plan, spec, or coding standards. Triggers: step completed from an implementation plan, feature implementation finished, significant code changes committed, pre-merge review needed, PR preparation, architecture compliance check. Also use when reviewing code quality, test coverage, or design pattern adherence after any non-trivial implementation work.
dependency-manager
/dependency-manager
Use proactively when working with dependencies — package.json, Cargo.toml, go.mod, pyproject.toml, requirements.txt, pom.xml, build.gradle. Triggers: vulnerability scanning, CVE remediation, version conflict resolution, dependency audit, bundle size optimization, lock file issues, breaking upgrades, peer dependency errors, unused dependency detection, license compliance, supply chain security review, npm/yarn/pnpm/pip/poetry/uv/cargo/maven/gradle issues.
documentation-specialist
/documentation-engineer
Use when creating or improving documentation — API docs, tutorials, architecture guides, README files, getting-started guides, migration guides. Triggers: API documentation with code examples, tutorial creation, documentation audit for staleness or gaps, architecture decision records, changelog writing, SDK/library documentation, inline documentation review, doc structure planning.
git-workflow-manager
/git-workflow-manager
Use when designing or improving Git workflows — branching strategies, merge policies, release automation, repository maintenance. Triggers: branching strategy design, merge conflict reduction, release process automation, semantic versioning setup, changelog generation, commit convention enforcement, monorepo management, Git hooks configuration, CI/CD integration with Git, history cleanup, branch protection rules, PR workflow optimization.
rust-specialist
/rust-engineer
Use proactively when working on Rust code — .rs files, Cargo.toml, cargo commands. Triggers: borrow checker errors, lifetime annotations, ownership/borrowing design, trait system design (object safety, async traits, HRTBs), async patterns (tokio, select!, cancellation safety), unsafe code review, performance optimization (allocations, iterator chains, zero-cost abstractions), macro development, workspace/feature-flag configuration, clippy/rustfmt issues, FFI bindings. Also use when reviewing or debugging Rust code, not just implementing.
Skills13
brainstorming
/brainstorming
You MUST use this before any creative work - creating features, building components, adding functionality, or modifying behavior. Explores user intent, requirements and design before implementation.
dispatching-parallel-agents
/dispatching-parallel-agents
Use when facing 2+ independent tasks that can be worked on without shared state or sequential dependencies
executing-plans
/executing-plans
Use when you have a written implementation plan to execute in a separate session with review checkpoints
finishing-a-development-branch
/finishing-a-development-branch
Use when implementation is complete, all tests pass, and you need to decide how to integrate the work - guides completion of development work by presenting structured options for merge, PR, or cleanup
receiving-code-review
/receiving-code-review
Use when receiving code review feedback, before implementing suggestions, especially if feedback seems unclear or technically questionable - requires technical rigor and verification, not performative agreement or blind implementation
