Gleam Backend Best Practices

Skill for Gleam server-side development on the Erlang target. Read the relevant reference before writing code.

Token Efficiency

All agents and commands using this skill MUST follow references/token-efficiency.md (from core). Use Read and Grep tools with targeted reads instead of reading entire files.

Core Backend Principles

Errors as Values — use 3-tier error handling (AppError), never exceptions.
SQL is the Contract — never edit generated sql.gleam files. Fix the .sql source.
No IO in Core — keep database access in handlers/services, separate from pure business logic.

Review Commands

When to use /otp-review:

After creating new actors or supervision trees.
When experiencing timeouts, deadlocks, or memory leaks.
