Claude Starter Kit

Diverge before planning — turn a fuzzy ask into scoped options and a chosen direction.

Health-check the installed kit — hooks executable, core.hooksPath set, gates wired.

Session handover — SESSION_STATE.md + /clear suggestion.

Spec-first planning — break down ambiguously scoped work with planner-csk.

Review pass — review + security + quality gates.

Senior .NET backend expert. Applies the project's backend-pattern skill (devarch-module = MediatR CQRS / IResult / AOP by default; a project may declare its own). Use proactively for new endpoints, handlers, validators, and controllers; small one-line edits stay on the main thread. Trigger phrases: "new handler", "write a command", "add a query", "endpoint", "business rule", "DevArchitecture module"

Commit message specialist (thin trigger). Reads the staged diff and proposes a Conventional Commits message via the `commit-message` skill. Writes no source; commits only with user approval. Trigger phrases: "commit message", "make a commit", "write a commit", "git commit", "commit the changes"

PostgreSQL + EF Core + Redis data-layer expert. Applies the `db-migration` skill. Use proactively for schema design, entity/config, migration generation and review, indexing, performance, and cache keying; trivial edits stay inline. Trigger phrases: "migration", "schema change", "new table", "index", "EF config", "data model", "redis cache"

Ops/DevOps expert. Use proactively for CI pipelines, safe deployment/release to servers, and production incident response and blameless postmortems. Deploy is DESTRUCTIVE and OUTWARD-FACING — no unapproved release to prod (§4.4). Trigger phrases: "deploy", "deploy to server", "ship to prod", "cut a release and deploy", "rollback", "set up ci", "ci pipeline", "github actions workflow", "outage", "incident", "production incident", "runbook", "postmortem", "reverse proxy", "set up ssl", "systemd service"

Stack-agnostic frontend expert — web (React/Next/Vue/Svelte/Angular), mobile (React Native/Flutter), desktop. The "how" lives in the `frontend` skill (mobile: `frontend-rn-expo`). Use proactively for new screens, components/pages, navigation, state, i18n, accessibility, responsive, and native-bridge work; small tweaks stay inline. Trigger phrases: "screen", "component", "page", "navigation", "routing", "UI", "responsive", "i18n interface", "state management"

Frontend accessibility audit (WCAG): semantic HTML, keyboard access, focus management, contrast, ARIA, screen readers. Trigger phrases: "a11y", "accessibility", "WCAG", "screen reader", "keyboard navigation", "contrast", "ARIA"

Spec-first planning: task breakdown, measurable acceptance criteria, dependency order, risk priority. planner-csk applies it; the plan goes to docs/PLAN.md. Trigger phrases: "plan", "spec", "task breakdown", "acceptance criteria", "roadmap", "how do we split this"

Root-cause a bug before touching a fix: reproduce, isolate, form and test a hypothesis, confirm the cause, then fix and verify. Stops guess-driven patching. For persistent, intermittent, or "already tried a few things" bugs. Trigger phrases: "debug", "root cause", "why is this failing", "intermittent bug", "can't reproduce", "still broken"

Architecture Decision Record: context-decision-consequences, for decisions that are expensive to reverse. Written under docs/adr/. Trigger phrases: "adr", "architecture decision", "decision record", "why this approach"

API contract design: resource naming, error model, versioning, pagination, backward compatibility, OpenAPI. A predictable interface that evolves without breaking consumers. Trigger phrases: "api design", "api contract", "api versioning", "openapi", "swagger", "rest contract", "breaking api change"
