What it does

Remix is an agent skill from epicweb-dev/epicflare. Build and review Remix 3 applications using the remix npm package and subpath imports. Use when working on Remix app structure, routes, controllers, middleware, validation, data access, auth, sessions, file uploads, server setup, UI components, hydration, navigation, or tests.

Its SKILL.md is about 6.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 12 other files, including reference files (for example `references/animate-elements.md`, `references/assets-and-browser-modules.md` and `references/auth-and-sessions.md`).

It sits in Backend & APIs, covering File uploads and storage and Linux administration. It works with npm. The repository describes itself as: A starter and reference for building full-stack web applications on Cloudflare Workers.

When your agent uses it

  • Working on Remix app structure
  • Tasks that involve File uploads and storage
  • Tasks that involve Linux administration

Example prompts

  • “/remix”

Workflow steps

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

  1. Classify the change. Decide whether it changes the route contract,
  2. Start from the server contract. Add or update app/routes.ts before
  3. Put code in the narrowest owner. Favor route-local code first, then
  4. Make the server path correct before adding browser behavior. A route
  5. Add middleware deliberately. Keep fast-exit middleware early and
  6. Validate input at the boundary. Parse and validate Request, FormData,
  7. Hydrate only when necessary. Prefer server-rendered UI. Use
  8. Test the narrowest meaningful layer. Prefer router tests for route
  9. Finish with verification. Re-read the route flow, confirm auth and

What it can do on your machine

Read from SKILL.md and the folder at commit f68b310. 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 6.3k tokens when it runs, and up to ~27k if it reads all its reference files. Until then it costs about 71 tokens; SKILL.md has 2,627 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~71
When it runs · the whole SKILL.md, loaded when a task matches
~6.3k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~27k

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

Auto-check passed

The automated check found no risky patterns in SKILL.md.

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 2,627 words (~6,275 tokens).

“Use this skill for end-to-end Remix app work. It should help the agent choose the right layer first, reach for the right package, and avoid the most common Remix-specific mistakes.”
