  1. ▌
    Surgical Changes · yakoshiq
    Implement fixes and small features as the smallest coherent change that fully solves the requested problem. Use when scope control, behavioral preservation, reviewability, or avoiding opportunistic cleanup matters.

  2. ▌
    Jane Street Style · yakoshiq
    Design, refactor, or review code when semantic clarity is the explicit goal, using precise domain names, explicit failures and effects, useful domain types, immutable data flow, and minimal accidental complexity. Use for Jane Street or clarity-first redesign, vague domain APIs, collapsed failures, primitive obsession, or mutation-heavy code - not ordinary bug fixes that should preserve local shape.

  3. ▌
    Tests That Matter · yakoshiq
    Write or review tests that prove observable behavior, failure semantics, invariants, and boundary cases. Use when adding tests, fixing brittle or mock-heavy tests, reviewing test quality, or when coverage exists but confidence does not.

  4. ▌
    Essential Comments · yakoshiq
    Add, keep, or remove code comments so only remarks that help humans remain - why, invariants, tradeoffs, and external constraints - not narration or restated code. Use when cleaning noisy comments, writing new code, reviewing comment quality, or when the user wants fewer/better comments.

  5. ▌
    Concurrency Invariants · yakoshiq
    Design, fix, or review concurrent and asynchronous code so atomicity, ordering, retries, idempotency, cancellation, timeouts, ownership, and partial success are explicit. Use for queues, workers, transactions, event handlers, parallel tasks, scheduled jobs, WebSocket/SSE, repeated delivery, concurrent requests, and race-condition fixes.
