glim

Use whenever editing Glim client TypeScript that involves Effect, async or fallible browser logic, external-boundary data, validation or decoding, WebSocket/fetch/file/localStorage APIs, or unsafe TypeScript cleanup. Apply Gleam-like explicit modeling, typed errors, exhaustive handling, and Effect best practices to the React/Vite client.

Use when you needs to write, edit, review, debug, test, or explain Gleam code in .gleam files, gleam.toml projects, Gleam package APIs, Gleeunit tests, BEAM or JavaScript target interop, or idiomatic Gleam design. Helps apply Gleam syntax, module layout, type modelling, Result-based error handling, pattern matching, standard-library usage, and official conventions and anti-patterns.
