Queue and PubSub patterns, background fibers, and graceful shutdown. Use for decoupling producers/consumers.

Expert regex pattern generation, optimization, testing, and explanation using deterministic AST-based construction. Use when user needs to create, test, optimize, or understand regex patterns, parse CLI commands, validate inputs, or build complex text matching patterns.

Effect-TS specialized research via deepwiki and submodules. Query Effect-TS/effect, tim-smart/effect-atom for verified patterns. Enforces grounded verification before implementation.

Use when Effect resource management patterns including Scope, addFinalizer, scoped effects, and automatic cleanup. Use for managing resources in Effect applications.

Resource safety with acquireRelease, Effect.scoped, and finalizers. Use when opening files, sockets, servers, or external handles.

Schema.TaggedStruct, Schema.TaggedClass, branded types, refinements, transformations. Pattern matching on _tag. Covers runtime validation, type inference, and schema composition for Effect-TS.

Effect Schema conventions and patterns. Triggers on Schema class creation, tagged unions, enums, type guards, or test fixtures using Effect Schema.

Define Effect schemas that are verified against domain types. Use when authoring or updating Effect Schema definitions, or when the user mentions schema/type parity, satisfies, or tsafe Equals checks.

Instructions on how to properly utilize Effect scopes for resource management, lifecycle concerns, etc.

Creating Effect.Service<>() classes, Context.Tag patterns, Layer composition. Decision trees for when to use which pattern. Covers service definition, dependency injection, and layer management.

Generate new Effect-TS services with proper patterns. Use when creating new services, layers, or adding methods to existing services.

Calculate and interpret effect sizes for statistical analyses. Use when: (1) Reporting research results to show practical significance, (2) Meta-analysis to combine study results, (3) Grant writing to justify expected effects, (4) Interpreting published studies beyond p-values, (5) Sample size planning for power analysis.

Effect patterns for SQL databases (Drizzle/Kysely/Prisma): services, transactions, retries, streaming, and observability.

Stream creation, consumption, transformation. Stream.async, Stream.fromSchedule, Stream.runForEach. Progressive data patterns for Effect-TS streams.

Stream creation, transformation, sinks, batching, and resilience. Use when building data pipelines with concurrency and backpressure.

Testing guidelines and patterns for Effect-based code.

Effect-TS snippets, templates, and examples for Effect usage.

Effect TypeScript best practices. Use when implementing Effect features like services, layers, error handling, or patterns. Triggers on: Effect, service, layer, schema, error handling.

Use this skill when writing, reviewing, or maintaining code comments. Apply these strategies to ensure comments explain intent rather than repeat code, use maintainable styles, and follow density guidelines. This skill covers comment types, style best practices, and performance considerations.
