Lustre & Frontend Best Practices

Skill for Gleam frontend development using Lustre. 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 Frontend Principles

Make Impossible States Impossible — Prefer sum types over Bools. Especially for async lifecycles: a form's save is SubmitIdle | SubmitSaving | SubmitSaved | SubmitFailed(err) (the model owns its data + a sibling save field); a page load is RemoteData. Never a Bool flag beside the data.
Parse, Don't Validate — Use FieldState(v, e) to wrap invalid UI state, rather than dictionaries.
Dumb Effects — Effects should be pure executors of I/O. Never pass the Model into an effect function.

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

Partly
It didn't

What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
