Code StructureAMUST USE when creating or editing any code file in any language — deciding how to split files, functions, classes, and modules, or whether to extract a shared helper, base class, or utility from duplicated code. Enforces the Single Responsibility Principle (one reason to change, file/function size limits, separation of concerns) and Avoid-Hasty-Abstractions (AHA / Rule of Three — prefer duplication over the wrong abstraction).toolspythongoVotes: 0GitHub stars: 3
DebuggingAMUST USE when fixing a bug, diagnosing an error, stack trace, exception, crash, failing or flaky test, or any 'why is X not working / returning the wrong value' investigation in any language. Enforces root-cause-before-patching: reproduce, trace the failure backward to its origin, test one hypothesis, then fix once — instead of guarding the symptom. Also covers the 3-attempts-then-question-the-design rule.code-qualitygodebuggingVotes: 0GitHub stars: 3
Docker Best PracticesCMUST USE when writing or editing Dockerfiles, docker-compose.yml, .dockerignore, or container configuration. Enforces multi-stage builds, layer caching, security hardening, Compose Watch for local dev, and health checks.developmentrustgoVotes: 0GitHub stars: 3

Drizzle OrmAMUST USE when writing or reviewing Drizzle ORM schemas, migrations, relational queries, or drizzle-kit configuration. Enforces identity columns over serial, proper relation definitions, migration safety, type inference, and query patterns.databasestypescriptgoVotes: 0GitHub stars: 3
ExpressAMUST USE when writing or reviewing Express routes, middleware, or error handling. Express 5 — automatic async error forwarding, the four-argument error handler, named wildcards, validation at the boundary, thin routes, and the security baseline every production app needs. Bundle covers tRPC v11 on Express.developmentrustgoVotes: 0GitHub stars: 3

SqlAMUST USE when writing SQL, creating tables, defining columns, choosing data types, writing migrations, creating indexes, diagnosing slow queries, reading EXPLAIN output, writing JOINs, defining relationships, using subqueries, or writing code with any ORM (Prisma, Django, SQLAlchemy, ActiveRecord, TypeORM, Sequelize, Drizzle).

Tanstack RouterAMUST USE when writing or editing TanStack Router routes, file-based routing, navigation, loaders, search params, beforeLoad auth guards, pendingComponent / loading UI, or route configuration. Enforces type-safe file-based routing, pending UI that prevents 'frozen on slow internet' navigation, auth checked once per subtree (not per page), loader caching with staleTime, and TanStack Query integration.developmentgoreactVotes: 0GitHub stars: 3
Testing Best PracticesAMUST USE when writing, reviewing, or modifying tests. Enforces Arrange-Act-Assert, assertions that fail when the code breaks (exact values, list ties, side effects, limits), factory-based test data, test isolation, mocking boundaries, and pyramid-balanced coverage; bundle covers mutation testing (Stryker, mutmut) for proving the tests would catch a break.developmenttypescriptpythonVotes: 0GitHub stars: 3
Typescript Best PracticesAMUST USE when writing or editing TypeScript types, interfaces, generics, type guards, error handling patterns, or tsconfig configuration. Enforces TypeScript 7.x strict-mode best practices and type safety patterns.developmenttypescriptgoVotes: 0GitHub stars: 3
Git Merge ConflictsAMUST USE when a git merge, rebase, cherry-pick, stash pop, or revert stops with conflicts — 'CONFLICT (content)', 'Automatic merge failed', 'could not apply', unmerged paths, or leftover <<<<<<< markers in a file. Enforces resolve-by-intent: read both sides against the merge base, keep both behaviours where they are compatible, and never pick a side wholesale. Also covers the inverted meaning of ours/theirs during a rebase, conflicts git does not mark (semantic and tree), lockfiles and migrat...developmentjavascriptpythonVotes: 0GitHub stars: 3
ResearchAMUST USE when asked to research, look up, investigate, or find out how something works — a library's API, a tool's config schema, a spec, a version's behaviour, 'what changed in X', 'does Y support Z' — and whenever you are about to state a fact about an external tool you have not opened this session. Enforces primary sources over recollection: route to the right lookup tool, follow every claim to the source that owns it, run the tool's own validator instead of guessing, and mark what stayed ...researchpythonrustVotes: 0GitHub stars: 3
