testing-patterns
Pytest templates and patterns for ETL pipeline testing - unit, integration, data quality.
test-reviewer

ui-code-auditor
Review source code for UI quality, accessibility violations, and performance anti-patterns. Static code analysis (NOT screenshot-based). Provides file:line references with severity, WCAG refs, and fix suggestions.
ux-brief
Create junior-dev-ready design systems through guided discovery before implementation
viewcomponent-coder
Build component-based UIs with ViewComponent and view_component-contrib. Use when creating reusable UI components, implementing slots and style variants, or building component previews. Triggers on ViewComponent creation, component patterns, Lookbook previews, or UI component architecture.
visual-validator
Use proactively after UI changes to verify they achieved their intended goals. Skeptical visual QA through screenshot analysis, accessibility verification, and design system compliance checking.
web-research
Research technical problems across GitHub issues, Stack Overflow, Reddit, and documentation. Gathers solutions from multiple community sources with structured findings. Triggers on search for solutions, find examples, research problem, community solutions, debug research.
wrangler-coder
This skill guides Cloudflare Workers and Pages development with Wrangler CLI. Use when creating Workers, configuring D1 databases, R2 storage, KV namespaces, Queues, or deploying to Cloudflare Pages.
learn
Extract cross-session patterns from git history, PRs, and handoffs, then recommend artifacts (skill/rule/hook/agent) based on frequency thresholds. Use when consolidating recurring patterns into durable artifacts. For single-session reflection, use `reflect` instead.
reflect
Reflect on the current session and suggest AGENTS.md improvements based on user corrections, repeated feedback, and patterns observed during interaction. Use when ending a session to encode lessons learned. Don't use for cross-session learning from git history - use `learn` instead.
skill-eval
Test and iterate on a skill using parallel eval runs. Spawns with-skill and baseline runs, grades results, and helps improve the skill based on feedback. Use when testing skill quality or iterating on skill improvements.
ai-work-governance

auto-decision-framework
Framework for automated decision-making during multi-step planning workflows. Classifies planning decisions as Mechanical (auto-decide silently), Taste (auto-decide but surface at gate), or User Challenge (never auto-decide).
