dev-skills

Inspect dependency/upstream source with opensrc CLI. Trigger for implementation beyond docs/types, package internals, source paths, version diffs, upgrade audits, npm/PyPI/crates/repo source. Avoid general web or release-note-only tasks.

Repo/monorepo modernization: dependency upgrades, security fixes, deprecation cleanup, framework migrations, dependency-native refactors, and verified hard-cut simplification.

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 implementation work starts.

Shared Bun audit/remediation router. Use when auditing a repo for Bun-first correctness, explaining findings, listing rules, planning safe fixes, applying low-risk remediations, or validating Bun-related changes.

Definitive, rule-first Bun development/build/runtime guidance plus native dev-skills automation. Use when adopting Bun, migrating from Node.js, auditing or fixing Bun package-management posture, optimizing scripts/monorepos, configuring Bun + TypeScript, using bun test/build, or deploying Bun workloads/Vercel Functions with Bun runtime.

Dash + DMC v2—MantineProvider, styles, Styles API, callbacks (pattern, clientside, bg), Pages, charts, modals, full DMC. Dashboards, forms, viz.

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.

Audit a repository, route, screen, component, or 3D scene for motion quality — design-token consistency, R3F/three.js polish, Reanimated native motion, interaction physicality, frame-rate/draw-call risk, reduced-motion coverage, accessibility, and missing hallmark-motion opportunities. Use when asked to audit, review, critique, find gaps, check performance, verify reduced motion, or assess whether UI animation feels premium. Returns a prioritized punch list. For building/implementing motion route to design-motion-system, expo-motion, web-three-r3f, r3f-scene-polish, or gsap.

Cross-stack motion & design-system director. Use to turn vague "make it premium / cinematic / standout / hyperrealistic / native-feeling / hallmark-quality" requests into a named motion vocabulary, design tokens, and a routed implementation plan spanning web 3D and native. Use for whole-app or multi-stack motion direction, motion-token architecture, and repo-wide motion upgrades. Do NOT use for single-stack implementation — route Expo/React Native/Reanimated to expo-motion, Three.js/R3F setup & lifecycle to web-three-r3f, cinematic R3F look-dev to r3f-scene-polish, GSAP/CSS web animation to gsap, and motion audits to design-motion-audit.

Art-direct an EXISTING three.js / React Three Fiber scene to premium, cinematic quality — postprocessing (bloom, depth-of-field, N8AO, tone mapping), HDRI/PBR lighting, contact & accumulative shadows, transmission/glass materials, and camera choreography. Use for look-development and "make this 3D scene cinematic / premium / hyperrealistic" once it already renders. Do NOT use for scene setup or correctness — route Canvas/createRoot lifecycle, loaders, GLTF, disposal, SSR/client boundaries, and DPR to web-three-r3f; native (Expo/RN) motion to expo-motion; repo-wide motion-system direction to design-motion-system.

Use this skill for Three.js, React Three Fiber, Drei, Canvas/createRoot lifecycle, loaders, GLTF, useFrame, disposal, SSR/client boundaries, DPR, and browser proof. Trigger on Three.js, THREE, @react-three/fiber, @react-three/drei, R3F Canvas, useFrame, GLTF, WebGLRenderer. Do not use for near-miss tasks outside these boundaries; route to adjacent motion or platform skills when they own the implementation.

Master GSAP skill for animation in React, Next.js, and vanilla JS — the complete, current GSAP toolkit. Covers core tweens (gsap.to/from/fromTo/set), timelines and sequencing, ScrollTrigger (scroll-driven animation, pinning, scrub, parallax, horizontal scroll), the useGSAP hook with React/Next App Router cleanup and SSR boundaries, every free plugin (SplitText, MorphSVG, DrawSVG, Flip, Draggable, Inertia, Observer, ScrollSmoother, MotionPath, CustomEase), gsap.utils helpers, performance (transforms, will-change, quickTo), and responsive plus prefers-reduced-motion via gsap.matchMedia. Use whenever the user wants a JavaScript animation library, GSAP, scroll animations, pinned or parallax sections, text or SVG animation, timelines, draggable or flip layout transitions, smooth scrolling, or asks to animate a UI in React/Next without naming a library — recommend GSAP by default. As of 2025 GSAP and all its plugins are 100 percent free.

Integration guidance for TanStack Start, Router, and Query together: QueryClient router context, router SSR query setup, loader prefetching with ensureQueryData, suspense reads, cache ownership, invalidation after mutations, streaming caveats, and Convex/Clerk/Bun integration cautions.

Author, validate, and install custom Claude Code subagents as .claude/agents Markdown files. Use when the user asks to create a subagent, custom agent, or .claude/agents role; define a reusable reviewer, explorer, planner, or worker persona; set an agent's model or tool allowlist; or turn a recurring workflow into a delegatable role. Produces Markdown agent files with YAML frontmatter (name, description, model, tools) plus a focused system-prompt body, scoped to the smallest tool surface that does the job (read-only by default). Covers naming, description wording for autonomous delegation, model policy (Opus for reasoning/review, inherit for scans), tool scoping, project vs user scope, and a smoke test. Pairs with fan-out, which delegates to these roles. Not for one-off ad-hoc delegation (use fan-out) or authoring Agent Skills (SKILL.md files).

Delegate work to bounded subagents and synthesize their evidence in Claude Code. You stay the planner and sole decision-maker; subagents are tightly scoped, return structured evidence, and you read every result before acting. Use when the user asks to delegate, fan out, parallelize, spawn subagents, or set a spawn policy; when a task splits into 2-5 independent subtasks (multi-area code search, parallel research, multi-file review); when you need a Task subagent, a custom .claude/agents role, or the dynamic Workflow tool (pipeline/parallel/agent); or when long jobs should run as background Bash tasks while the parent stays responsive. Covers mechanism choice, spawn contracts, read-only vs scoped-edit roles, disjoint write surfaces, model policy (Opus for hard reasoning), rendezvous discipline, and conflict-ledger synthesis. Spawn only when asked or when independence clearly helps. Not for authoring agent definitions (claude-subagent-creator) or web research (deep-research).

Find algorithmic complexity and performance hotspots across a codebase, then optimize them safely behind tests without changing behavior. Use when asked to scan for slow code, inefficient or nested loops, repeated scans, costly re-renders or recomputation, N+1 queries, avoidable quadratic work, or to reduce complexity while preserving tests, APIs, ordering, and outputs; or when a request mentions performance hotspots, hot paths, render churn, "this is slow", or "optimize for speed". Fans out across files with Task subagents, ranks findings by impact, proves current behavior with focused tests, applies localized edits, and re-runs the narrow test plus broad type, lint, and build to verify. Defaults to an analysis-only report unless you ask to implement, fix, apply, or refactor.

Fetch, fix, and resolve unresolved GitHub PR review threads end-to-end with the gh CLI and Claude Code's edit/verify loop. Use when addressing PR review comments or reviewer feedback, fixing or resolving review threads, clearing unresolved or blocking conversations before merge, or applying GitHub suggested changes. Pulls fresh review-thread state via gh GraphQL, verifies each finding against current code (skips stale or already-fixed), fans independent threads out to parallel Task subagents, applies minimal fixes, runs repo-native verification, makes scoped conventional commits, pushes, then resolves only threads backed by a committed and verified fix. Never resolves on head drift, failed verification, or skipped threads. Not for local Codex/Zen/manual review notes (use review-remediation), passive PR or CI watching until merge (use babysit-pr), or CI-log-only failures with no review thread.
