Explains code with visual diagrams and analogies. Use when explaining how code works, walking through a codebase area, or when the user asks "how does this work?" Don't use for modifying code, fixing bugs, generating new implementations, or multi-session concept learning (use /teach).
Fortify existing code by splitting large functions, adding edge-case coverage, and backfilling unit tests. Use when user asks to "fortify", "harden", "bulletproof", "make robust", "make solid", "strengthen", "add missing tests", "split functions", or wants to improve reliability of existing code. Don't use for new…
Front-load UI construction decisions — component boundary and prop API, where state lives, data/async, the required UI states (loading/empty/error), responsive behavior, and accessibility by construction. Use when creating or refactoring a component, page, or design-system primitive. Don't use for pure logic (tdd)…
A relentless interview to sharpen a plan or design. Use when the user wants to stress-test a plan, pressure-test assumptions, or says "grill me" or "poke holes in this". Don't use for code review (use /code-review) or gathering initial requirements (use /spec).
Compact the current conversation into a handoff document for another agent to pick up. Use when the user wants to hand off, transfer context to a fresh session, or says "write a handoff". Don't use to summarize for the current session (just answer) or to brief on plan progress (use /test).
Harden code proactively against vulnerabilities at the boundary where untrusted input enters the system. Use when implementing auth, handling user input, storing or transmitting sensitive data, integrating external APIs, adding file uploads, or any code that crosses a trust boundary. Don't use for reactive secret…
Audit internationalization coverage and find hardcoded strings. Use when user asks to "check i18n", "/i18n", "find hardcoded strings", "check translations", or wants to verify translation coverage. Don't use for backend string extraction, non-frontend code, or projects without an i18n library.
Run linting and formatting checks. Use when user asks to "run linter", "/lint", "check linting", "fix lint errors", or requests code linting/formatting. Don't use for running tests or type-checking only.
Audit frontend bundle size and performance. Use when user asks to "audit performance", "/perf-audit", "analyze bundle", "check bundle size", or wants to find performance bottlenecks. Don't use for backend performance, database query optimization, or projects without a frontend build step.
Turn a spec into a multi-phase implementation plan using tracer-bullet vertical slices. Use after /spec when a spec exists at .specs/specs/ .md, or when the user asks to break work into phases or slices. Don't use without a spec, or for single-file changes with obvious scope.
Fix prose formatting, typos, and clarity issues in markdown or text files. Use when user asks to "fix dashes", "fix typos", "clean up text", "improve sentences", or "/prose-fix". Don't use for code style, linting, or full rewrites.
Build a throwaway prototype to flesh out a design — a runnable terminal app for state/business-logic questions, or several radically different UI variations toggleable from one route. Use when the user wants to explore or compare design directions before committing, or says "prototype", "mock up", or "try a few…
Investigate a question against primary sources and capture the findings as a cited Markdown file. Use when the user wants a topic researched, docs or API facts gathered, or reading legwork delegated to a background agent. Don't use for implementing against pinned dependency versions (use source-driven) or searching…
Orchestrated REVIEW phase — fan out parallel, read-only reviewers over a diff (scope-detected audit skills AND independent agent lenses), then consolidate into one severity-ranked verdict. Use for a full pre-ship review, "review/validate this PR", or "spawn agents to review". Don't use to implement fixes (use /build…
Structurally edit and improve article drafts — reorder sections, tighten arguments, improve clarity. Use when user asks to "revise", "improve my article", "edit my draft", or "/revise". Don't use for typo fixes or formatting (use prose-fix), code documentation, or non-article content.
Check for sensitive data in repository. Use when user asks to "check for sensitive data", "/safe-repo", or wants to verify no company/credential data is in the repository. Use --diff mode to scope to staged + unstaged changes only (e.g., before commit). Don't use for general code review, adding .gitignore entries, or…
Set up Husky pre-commit hooks with lint-staged (Prettier), type checking, and tests. Use when user asks to "add pre-commit hooks", "setup husky", "setup pre-commit", "configure lint-staged", or wants commit-time formatting/typechecking/testing. Don't use for running linters manually or writing tests.
Implement features using official docs for exact dependency versions instead of training data. Use when user asks to "check the docs", "use official docs", "source-driven", or when implementing with unfamiliar APIs/libraries. Don't use for well-known stdlib APIs or project-internal code.
Create a spec (PRD) through user interview, codebase exploration, and module design. Use when starting a feature with unclear requirements, when the user asks to spec or define what to build, or says "write a spec" or "write a PRD". Don't use when requirements are crisp and a plan already exists (use /plan or /build).
VERIFY phase — prove the code works. Run validation (lint, types, tests) plus coverage on changes, and when a plan exists verify its checkboxes against the codebase. Use after /build, when the user asks to verify, test, or confirm work holds up, or to check plan progress. Don't use to implement phases (use /build) or…
Fetch unresolved review comments on a GitHub PR (Copilot bot + human reviewers), verify each against the current code, and classify as Address / Skip / Optional / Discuss with a one-line rationale. Use when the user asks which review comments to address, to triage Copilot/reviewer feedback, sort signal from noise on a…
