Detect environment variables and secrets that leak from the server into the client bundle via loader return values, hydration state, or accidental imports of server-only modules from client code paths. Use when asked to "audit secrets", "find leaked env vars", "is my API key exposed", "check client bundle for secrets", or "scan for credential leaks".

Audit pracht route loaders for serializability, leaked secrets, unsafe loader caching, browser-only API misuse, and missing AbortSignal plumbing. Use when asked to "audit loaders", "check loader data", "find serialization bugs", "are my loaders safe", or "loader security review".

Pracht deployment guide. Walks through adapter configuration, building, and deploying to Node.js, Cloudflare Workers, or Vercel. Handles wrangler config, Docker and production checklist. Use when asked to "deploy", "set up deployment", "configure adapter", "deploy to cloudflare", "deploy to vercel", or "production build".

Adapter-aware pre-deployment checklist for pracht apps targeting Node, Cloudflare Workers, or Vercel. Catches the issues that only surface in the production runtime: missing env vars, Node-only APIs in Cloudflare bundles, ISG manifest absence, oversized edge bundles, missing wrangler/vercel config. Use when asked to "pre-deploy check", "ready to ship?", "deployment checklist", "is my build production-safe", or before running `wrangler deploy` / `vercel deploy`.

Recommend the right pracht render mode (ssg, isg, ssr, spa) for each route based on what its loader actually does. Most apps pick a mode once and never revisit; this skill surfaces routes that are mis-tuned. Use when asked to "tune render modes", "make my site faster", "should this route be SSG", "audit render modes", or "review SSG/ISG/SSR choices".

Migrate a Next.js application to Pracht. Converts App Router pages, layouts, middleware, API routes, data fetching, and metadata to pracht equivalents. Handles React→Preact, className→class, server components→loaders, and manifest wiring. Use when asked to "migrate from next", "convert next.js app", "port from next to pracht", "nextjs migration", or "switch from next".

Add or maintain pracht typed routes, typed links, route-object navigation, and generated href helpers. Use when asked to "add typed routes", "fix typed links", "replace hard-coded hrefs", "run typegen", or make navigation route-id based instead of string based.

Pracht framework-aware debugging. Systematically investigates route matching, loader/API route errors, rendering issues, middleware, API routes, HMR, and build problems. Uses pracht's architecture knowledge to find root causes fast. Use when asked to "debug this", "fix this bug", "why is this broken", "blank page", "hydration mismatch", or "404 on my route". Proactively suggest when the user reports errors or unexpected behavior in a pracht application.

Use when hardening npm package release workflows with trusted publishing, OIDC, GitHub environments, pinned GitHub Actions, disabled publish-path caching, Changesets release PRs, direct tag-based npm publish flows, staged publishing, or npm release-supply-chain reviews.

Use when migrating React code or libraries to Preact, configuring preact/compat, bundler aliases, react/jsx-runtime, react-dom, Jest, Node SSR aliases, or diagnosing duplicate React/Preact copies and compat behavior differences.

Use when enabling preact/debug, interpreting Preact debug warnings, invalid HTML nesting or table parser problems, hydration mismatch diagnostics, duplicate keys, invalid refs/events, or component stack traces.

Use when building or debugging Preact forms, controlled or uncontrolled inputs, onInput versus onChange, checkbox, radio, select, textarea behavior, hydration of form state, cursor preservation, or compat event normalization.

Use when Preact hooks fail with invalid hook calls, __H undefined or null errors, mixed CJS/ESM imports, no-build import maps, duplicate Preact copies, useId SSR mismatches, or effect scheduling problems.

Use when Preact SSR, prerendering, hydrate(), Suspense, lazy, streaming SSR, renderToStringAsync(), or browser-parsed HTML produces hydration warnings, duplicate nodes, mismatched DOM, lost focus, stale fallback markup, or client-only conditional render bugs.

Use when starting a Preact app, choosing Vite versus no-build HTM or import maps, setting JSX pragmas, CDN ESM imports, create-preact, or integrating Preact into an existing build pipeline.

Use when implementing or debugging @preact/signals-core, signal, computed, effect, batch, untracked, action, createModel, signal.value tracking, object or array updates, and reactivity that appears stale or over-eager.

Automates interactions for Apple-platform apps (iOS, tvOS, macOS) and Android devices. Use when navigating apps, taking snapshots/screenshots, tapping, typing, scrolling, extracting UI info, or collecting logs, network inspection, and perf snapshots across mobile, TV, and desktop targets.

Inspect and profile React Native component trees from agent-device. Use when debugging React Native props, state, hooks, render causes, slow components, excessive re-renders, or questions like why a component re-rendered.

Inspect Pi session history, analyze repeated assistant mistakes, and turn durable learnings into corrective skills or context updates. Use when the user asks to review previous sessions, learn from a failed interaction, or stop the model repeating a mistake.

Maintain Pi extensions in this repository with explicit runtime boundaries, tests, docs, and verification.

Build AI agents on Cloudflare Workers using the Agents SDK. Load when creating stateful agents, durable workflows, real-time WebSocket apps, scheduled tasks, MCP servers, or chat applications. Covers Agent class, state management, callable RPC, Workflows integration, and React hooks. Biases towards retrieval from Cloudflare docs over pre-trained knowledge.

Guidelines for state management with createModel, Show, and For using Preact Signals.
