Write Effect code grounded in its current source.
Guides agents to write, review, and refactor idiomatic Effect v4 TypeScript code using source-backed patterns.
When to use it
Use when writing, reviewing, or refactoring Effect code, including services, dependency injection, errors, schemas, tests, and project setup.
It changes how the agent writes, reviews, and refactors Effect code by requiring official source checks and prescribing coding patterns.
