Write Svelte 5 components and SvelteKit pages following the project's frontend conventions — dark theme, mobile-first, minimalist Tailwind, modern CSS.
Create a new Architecture Decision Record (ADR) in docs/decisions/. MUST be used whenever writing an ADR — never create ADR files manually. Picks the next sequential number, fills the template, and updates the ADR table in README.md.
Run E2E and unit tests. Supports smoke tests (quick, any DB), deterministic tests (seeded DB, full suite), unit tests, or individual test files. Also covers ad-hoc verification via Playwright MCP.
Audit the current branch for loose ends before merge or plan close — stale docs, untested defensive code, partial wiring, coverage regressions, leftover TODOs. Reports findings; does not fix. MUST be used as part of plan-mode step 4 ("Branch audit before closing"); also useful ad-hoc whenever a branch is asked to be merge-ready.
Stage and commit changes with an emoji conventional commit message. Reviews staged/unstaged diffs, suggests a message, and creates the commit.
Run linting and formatting checks on the project. Uses ESLint, Prettier, and svelte-check. Reports issues and offers to auto-fix.
Review the current session for learnings worth persisting. Prefers committed files (CLAUDE.md, skills) over memory — memory is only for personal/user-specific things.
MUST be used whenever generating, creating, or managing Drizzle ORM database migrations — including after any schema change (adding columns, tables, indexes). Handles migration naming conventions and journal updates.
