16-phase deterministic workflow. Auto-invoke for any non-trivial coding task that will result in file changes. Triage classifies the task (TRIVIAL/SMALL/MEDIUM/LARGE) and skips phases for trivial fixes. Do NOT invoke for read-only questions, code explanations, search-only tasks, or pure conversations.

Use when the user needs to run GitNexus CLI commands like analyze/index a repo, check status, clean the index, generate a wiki, or list indexed repos. Examples: "Index this repo", "Reanalyze the codebase", "Generate a wiki"

Enforces Effect-TS patterns for services, errors, layers, and atoms. Use when writing code with Effect.Service, Schema.TaggedError, Layer composition, or effect-atom React components.

Routes backend Effect tasks to the right skills, invariants, and reviewer. Use when modifying backend/src/** or shared schemas backing a backend feature. Returns the skill list to load, repo invariants to enforce, mandatory tools, and the required reviewer follow-up.

Routes frontend TanStack/React tasks to the right skills, invariants, and reviewer. Use when modifying frontend/src/** or shared schemas backing a frontend feature. Returns the skill list to load, repo invariants to enforce, mandatory tools, and the required reviewer follow-up.

Instrument backend Effect code with OpenTelemetry traces, metrics, and structured logs via @effect/opentelemetry and @laundry-app/observability. Use when adding repository methods, custom counters or histograms, HTTP middleware metrics, debugging the OTel/Prometheus/Loki/Grafana stack, or wiring new Grafana dashboard panels.

Nix flakes, nix-darwin, NixOS, and home-manager development assistance

Write comprehensive MDX documentation for KomoUI (Kotlin Modern UI) components. Use when the user asks to write, update, or improve docs for a component in this project — especially when given a GitHub source file URL or asked to make docs "comprehensive". Handles fetching Kotlin source via gh CLI, reading existing MDX patterns, and producing complete docs with usage sections, API reference tables, and correct KMP code examples.

Provides idiomatic Kotlin implementation patterns including coroutine concurrency, Flow stream handling, multiplatform architecture, Compose UI construction, type-safe DSL design. Use when building Kotlin applications requiring coroutines, multiplatform development, or Android with Compose. Invoke for Flow API, KMP projects, DSL design, sealed classes, suspend function, Android Kotlin, Kotlin Multiplatform.
