Build and Review a Remix App

Find Context and Documentation

Read the relevant installed documentation before using unfamiliar Remix APIs:

1. Read the app's AGENTS.md, package.json, and tsconfig.json, then inspect the code that owns the behavior being changed.
2. Search node_modules/remix/INDEX.md by task, export, or keyword, for example grep -i 'session' node_modules/remix/INDEX.md.
3. Follow the index to the relevant guide for the workflow, then the package README for exact imports, options, behavior, and examples. If there is no relevant guide, use the API README and existing app patterns.

Treat the installed documentation as canonical, including when it differs from this skill. Do not rely on remembered Remix 2 patterns or online APIs from a newer version. If the installation has no index, inspect its package.json exports and matching installed READMEs, source, and types.
