Use when the user wants to start factory work on a work item, check factory status, drive a run forward, author a new factory…
Skill Claude CodeCodex
Use this skill when authoring or organizing components in Solid (SolidJS): the run-once lifecycle, capital-letter naming (lowercase is parsed as a DOM tag), default vs named exports, distinguishing the component function from the JSX it returns, and choosing the right TypeScript component type. Covers Component…
Skill Claude CodeCodex
Use this skill when configuring a Solid (SolidJS) project: tsconfig.json for JSX, vite.config.ts (or vitest.config.ts for tests) with vite-plugin-solid, environment variables (Vite's VITE for client-exposed, server-only otherwise), .env files and modes, app.config.ts in SolidStart (Vinxi), and bundler integration with…

Use this skill when sharing data across a Solid (SolidJS) component tree without prop drilling: theme, current user, i18n, design-system tokens, anything that many components in a subtree need. Covers createContext (with optional default value to avoid | undefined), to scope the data, useContext to read it (returns…
Skill Claude CodeCodex
Use this skill when running side effects in Solid (SolidJS): logging, DOM manipulation, network requests, subscriptions, intervals, anything triggered by reactive state changes.

Skill Claude CodeCodex
Use this skill when reasoning about why Solid (SolidJS) code is or is not updating, or before any non-trivial Solid task. Covers Solid's core philosophy: components run once, reactivity is fine-grained, signals are getter functions, props are a reactive proxy that must not be destructured, JSX placement determines…
