Code Reviewer
Performs structured pull-request and code reviews for correctness, security, performance, and maintainability. Use when the user shares a diff, asks to review a PR, requests feedback on a file or snippet, or says 'review this code', 'what's wrong with this', or 'LGTM check'.
Test Writer
Designs and writes unit, integration, and contract tests aligned to the repo's existing framework and conventions. Use when the user asks for tests, coverage, 'add tests for', property-based cases, snapshot updates, or test plans for a module.
Commit Message Writer
Produces Conventional Commits-style messages from diffs or verbal summaries. Use when the user says 'write a commit message', 'conventional commit for this diff', prepares a squash merge message, or needs changelog-ready subjects and bodies.
Refactor Guide
Analyzes code for smells and technical debt and outputs a prioritized, low-risk refactor plan with before/after examples. Use when the user asks to refactor, simplify, reduce complexity, pay down debt, or 'make this cleaner' without changing behavior.
API Documenter
Produces OpenAPI 3, markdown API guides, and runnable examples from route code, handlers, or informal specs. Use when the user asks for Swagger/OpenAPI, endpoint docs, curl examples, or 'document this API'.
Bug Hunter
Triages errors, stack traces, and flaky symptoms into hypotheses, root cause, and minimal fixes. Use when the user pastes an exception, asks 'why is this failing', describes intermittent behavior, or needs a repro recipe.
SQL Query Builder
Turns natural-language analytics questions into safe, parameterized SQL with explanations and index notes. Use when the user asks for a query, report SQL, joins, aggregations, or 'how do I fetch X from these tables' and names PostgreSQL, MySQL, SQLite, or generic SQL.
PR Reviewer
Reviews a pull request as a whole: intent, architecture, tests, rollout risk, and merge readiness—not only line nits. Use when the user shares a PR description, diff summary, or asks 'is this ready to merge', 'blocking issues', or team-level feedback.
README Writer
Produces a production-ready README from repo cues: value prop, install, usage, config, API surface, contributing, and license. Use when the user asks for a README, 'docs for GitHub', onboarding doc, or project overview from package.json / structure.
Figma to Code
Implements UI from Figma specs, MCP exports, or annotated screenshots into accessible components using design tokens and the project stack (e.g. React + Tailwind). Use when the user says 'build this frame', 'implement from Figma', shares node specs, or wants pixel-faithful UI with responsive behavior.
