Use when adding a CodeMirror 6 extension to the editor — phrases like "add Tab/Shift+Tab support", "add a keymap", "support Ctrl+B for bold", "add a dark theme toggle", "swap the CodeMirror theme", "add a CodeMirror extension". Several roadmap items (Tab support, key shortcuts, dark mode for the editor) all flow through this skill. Enforces the lifecycle invariants documented in `src/components/Editor/CLAUDE.md`.

Use when the user asks to commit changes, create a commit, or stage and commit. Drafts a commit message following Lumark's `<type>(<issue#>): <subject>` convention, deriving the issue number from the current branch name (e.g. branch `47-add-delete-buttons-to-files` → `(47)`). Selects `feat` / `fix` / `chore` / `doc` based on what's changed.

Use whenever the user asks about a library, framework, SDK, API, CLI tool, or cloud service — even well-known ones (React, Tauri, CodeMirror, Tailwind, Vite, ESLint, lucide-react, react-markdown, remark, rehype, Rust crates, etc.). Includes API syntax, configuration, version migration, library-specific debugging, setup, CLI usage. ALWAYS consults Context7 (`mcp__context7__*`, configured in `.mcp.json`) — never relies on training data for library docs. Skip for: refactoring, writing scripts from scratch, debugging business logic, general programming concepts.

Use when `yarn lint` reports errors or warnings, or when the user asks to fix lint issues, format code, or clean up style. Triggers on phrases like "fix lint errors", "the linter is failing", "run lint:fix", "clean up style". Reads `eslint.config.mjs` to understand which rules apply and respects existing repo conventions.

Use when the user wants to add a new Tauri IPC command — anything reachable via `invoke('name', ...)` from React. Triggers on phrases like "add a Tauri command", "expose X to the frontend", "create a new `#[tauri::command]`", "add IPC for Y". Enforces the three-step contract (Rust fn + invoke_handler! registration + frontend wiring) and the file-extension contract.

Use when the user wants to **call an existing Tauri command** from a new place in the frontend — adding a button that loads a file, a UI action that triggers an existing IPC, etc. Distinct from creating a new command. Triggers on phrases like "call `load_files` from this component", "wire up the existing IPC", "invoke X from the frontend". For creating NEW commands, use `ipc-command-creator` instead.

Use when the user wants to start work on a specific GitHub issue — phrases like "let's work on issue

Use when the user wants a new reusable UI primitive under `src/components/UI/` — Button, Input, Modal, Textarea, Card, Badge, Tooltip, etc. Also use when extracting feature-local markup into a shared UI primitive. Triggers on phrases like "add a Textarea component", "create a Modal UI primitive", "extract this into a shared UI component". Enforces the pattern documented in `src/components/UI/CLAUDE.md` and `.claude/rules/ui-components.md`.

Verify the app actually works — lint, typecheck/build, then boot it and drive the real routes. Run before saying a change is done. Use when asked to verify, test, or confirm something works.

Scaffold a new presentational primitive in components/UI following this project's non-negotiable component pattern (folder per component, types.ts, no FC, PropsWithChildren at the signature, Record variant maps, semantic tokens only). Use when adding a Button/Input/Modal-style reusable component, or when asked to add something to the UI library.

Add or change a color/design token correctly — raw palette in base.css, semantic alias, Tailwind mapping in globals.css, plus a WCAG AA contrast check in both themes. Use when a component needs a color that does not exist yet, or when changing the palette.

Add a news provider adapter (Guardian, NYT, NewsAPI, …) that normalizes one API's response onto the internal Article type. Use when adding or changing a data source, wiring an API key, or touching lib/sources. This is the architecture the case study is graded on — open-closed and dependency inversion made concrete.
