Remix

What it does

When your agent uses it

• Application structure
• Browser interaction
• Not for implementing Remix framework packages

Example prompts

• “/remix”

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

1. 1Read the app's AGENTS.md, package.json, and tsconfig.json, then inspect the code that owns the behavior being changed.
2. 2Search node_modules/remix/INDEX.md by task, export, or keyword, for example grep -i 'session' node_modules/remix/INDEX.md.
3. 3Follow the index to the relevant guide for the workflow, then the package README for exact imports, options, behavior, and examples. If…

What it can do on your machine

Read from SKILL.md and the folder at commit ef2c594. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript).

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  No URLs in SKILL.md.

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Remix loads about 1.3k tokens when it runs. Until then it costs about 60 tokens; SKILL.md has 580 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~60

When it runs · the whole SKILL.md, loaded when a task matches

~1.3k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Builds, reviews, and refactors Remix 3 apps using the remix package and remix/* imports. Use for application structure, routing, middleware, data, auth, UI, browser interaction, and tests; not for implementing Remix framework packages.
