Use, cite, and maintain consistency with Accepted Architectural Decision Records under docs/adrs/. Load relevant ADRs for architecture-shaped work, flag conflicts (refuse silent drift; allow human-owned exceptions), and help update supersession/index hygiene. Does not propose, discuss, or approve ADRs — humans own the…

Refactor concepts implicated by the current uncommitted change before commit. Use concept-bounded scope even when completion requires untouched code, but Jidoka-stop before unapproved cross-subsystem refactoring. Remove duplication, unclear naming, shotgun surgery, dead / test-only / redundant code, and oversized…

Prepare, refine, order, and assess a real-product backlog for an upcoming LeSS in Action (LIA) class. Use when selecting class-sized product features, investigating how much of an idea already exists, turning feature themes into vertical interdependent user stories, adding high-value items, or facilitating Product…

Decompose work into GSD-aligned plans whose executable units are Behavior/Structure slices (one observable behavior per slice, stop-safe). Use when planning new features, breaking down large tasks, or when a fix / make-test-pass breakdown has overrun the time-box (see planning.mdc). Triggers on: plan, decompose…

Profile a test suite, optimize the slowest top 10% in grouped slices, and close with a re-profile. Works for unit tests (JUnit/Vitest/…; "small test" style) in any sub-project (backend, frontend, cli, mcp-server) or Cypress E2E. Use when the developer asks to optimize, speed up, or profile slow tests, top 10% slowest…
