Development

Developer inquiry skill for technical investigation, validation, and decision-making. Use when exploring unfamiliar technology, validating approaches with spikes, comparing options, or making architecture decisions. Covers the full thinking process from "I don't know" to confident decision.

OpenFeature vendor-agnostic feature flag SDK with standardized API across languages. Covers SDK installation, flag evaluation, providers, and hooks. Use when implementing feature flags, A/B testing, canary releases, or when user mentions OpenFeature, feature toggles, or progressive rollouts.

Gate 0 of the development cycle. Executes code implementation using the appropriate specialized agent based on task content and project language. Handles TDD workflow with RED-GREEN phases. Follows project standards defined in docs/PROJECT_RULES.md.

Check and configure testing frameworks and infrastructure

Show infrastructure standards compliance status (read-only)

Comprehensive UI/UX design and implementation skill covering visual design principles, color theory, typography, spacing systems, layout composition, accessibility (WCAG 2.2), animation, and systematic implementation workflows

Check and configure Sentry error tracking for project standards

Human-in-the-loop iterative development. Use when requirements will emerge during implementation, decisions need human approval at each step, or work will span multiple sessions with frequent feedback loops. Creates problem statement, decisions log, runbook, and progress tracking.

Security scanning: dependency automation, SAST, secrets detection. Use when setting up Renovate/Dependabot, CodeQL, or TruffleHog in CI, or creating a SECURITY.md policy.

Master skill for all Frontend Vue 3 development. Covers Components, Pinia, VueUse, Reactivity, CSS, and UI/UX.

Check and configure release-please workflow for project standards

Check and configure README.md with logo, badges, features, tech stack, and project structure

Set up .pre-commit-config.yaml: hooks for the project type at current revs. Use when installing pre-commit in a repo, auditing stale hook revs, or migrating to pre-commit.

Check and configure modern package managers (uv for Python, bun for TypeScript)

DEBUG Pomodoro timer state issues, incorrect countdown behavior, and timer synchronization problems. Fix when timer won't start, time display is wrong, or timer gets stuck. Use for timer state management, countdown logic, and session persistence.

Check and configure memory profiling with pytest-memray for Python projects

MASTER Pinia task store debugging covering synchronization, CRUD operations, state persistence, IndexedDB conflicts, advanced state management, and complex store architecture. Fix when tasks don't save, disappear unexpectedly, don't update in UI, backup systems read wrong data, store actions fail, or advanced performance issues occur. CRITICAL: All store fixes MUST be tested with Playwright before claiming success.

Check and configure Makefile with standard targets for project standards

DEBUG task store synchronization, task creation/deletion bugs, and state persistence problems. Fix when tasks don't save, disappear unexpectedly, or don't update in UI. Use for Pinia task store, task CRUD operations, and data persistence.

Set up linters (Biome, Ruff, Clippy) and wire them into pre-commit and CI. Use when a repo has no linter config, migrating ESLint to Biome, or auditing lint rules.

Check and configure Justfiles with standard recipes. Use when setting up a Justfile, auditing for missing recipes, or migrating from Makefile to Justfile.

DEBUG Pinia store state not updating, persistence conflicts, and store synchronization issues. Fix when store actions don't work, state gets stale, or localStorage hydration problems occur. Use when Pinia stores behave unexpectedly.

actions/deploy-pages workflow publishing a docs site (MkDocs, TypeDoc, Docusaurus) to GitHub Pages. Use when setting up Pages or migrating off peaceiris/actions-gh-pages.

Set up formatters (Biome, Ruff format, rustfmt) with pre-commit and CI format checks. Use when a repo has no formatter, replacing Prettier or Black, or unifying monorepo style.
