AgentSkills library: reusable skills for AI coding agents (AI SDK, Codex, LangGraph, Supabase, Docker, Vitest, pytest, Streamlit, Zod).
This repository also configures its own agents. See what dev-skills tells them →
Skill Codex
Create, validate, install, and smoke-test Codex custom subagents from TOML templates. Use for /.codex/agents or project .codex/agents roles, subagent templates, model and sandbox defaults, or reusable agent packs.
Skill Codex
Bounded subagent delegation and synthesis. Use for explicit subagent, delegation, fan-out, spawn policy, custom agent routing, wait behavior, and evidence-first synthesis.
Skill Codex
Production-ready Supabase integration patterns for Next.js/React/TypeScript applications. Use when working with Supabase for (1) SSR authentication with @supabase/ssr, (2) Database operations and migrations, (3) Row Level Security (RLS) policies, (4) Storage buckets and file uploads, (5) Realtime channels and…
Skill Codex
TanStack Start/Router/Query integration: QueryClient context, SSR/prefetch, cache ownership, invalidation, and streaming.
Skill Codex
TanStack Query v5: queryOptions/keys, caching, mutations, invalidation, optimistic updates, SSR hydration, and infinite queries.
Skill Codex
TanStack Router: file routes, generated trees, typed root context, loaders/deps, validated search params, code splitting, and errors.
Skill Codex
TanStack Start: server functions/routes, middleware, SSR, auth, execution boundaries, and deployment for full-stack React apps.
Skill Claude CodeCodex
Internal engineering docs: specs, ADRs, architecture, runbooks, migrations, rollout plans, and maintainer guides.
Skill Codex
Generate repo-local dependency upgrade packs under .agents/plans/upgrade/topic-slug/ with a playbook, trigger prompt, operator mode, and canonical manifest. Use when Codex needs to research an anchor package, expand related dependencies, detect target repo context, and create a reusable upgrade folder before any…
Skill Codex
Generic Vitest/TypeScript testing: write or repair tests, triage flakes, tune monorepo config, and reduce local/CI test time.
Skill Codex
Conduct WCAG 2.2 accessibility audits with automated testing, manual verification, and remediation guidance. Use when auditing websites for accessibility, fixing WCAG violations, or implementing accessible design patterns.
Skill Codex
Review UI code against the Vercel Web Interface Guidelines: a broad, terse pre-commit sweep across interaction, forms, layout, content, performance, and accessibility. Use for a fast checklist pass over a diff. For depth in any single domain, and for a holistic cross-discipline review, use the better- suite instead.
Skill Codex
Zod v4 TypeScript schema design, Zod 3 to 4 migration, validation boundaries, errors, codecs, JSON Schema/OpenAPI, metadata, Zod Mini/Core, RHF/tRPC/Hono/Next integrations, and rule-aware audits for Zod 4.4.3.
Skill Codex
Adversarial design, frontend, and motion review for web or mobile branches. Use to inspect a dirty UI worktree, prove behavior in a real browser or device, measure motion, performance, and accessibility, and implement one canonical end state.
Skill Codex
Pre-merge branch and PR closeout. Use to identify and implement follow-up work, hard cuts, dependency-native simplification, validation coverage, docs alignment, and merge-readiness fixes.
Skill Codex
Validation routing and test-failure triage for any repository. Use to select the right gates, author deterministic tests, reproduce CI failures, or diagnose flaky suites.
Skill Claude CodeCodex
Manage shadcn/ui components: add, search, fix, style and compose, with registry and component docs. Applies to any project with a components.json. Triggers on "shadcn init" or a --preset code.
