protected-files

protected-files is a cursor rule for Cursor from hoshikitsunoda/figma-plugins-vibe-coding-template. It costs 130 tokens per session, scanned A, original, MIT.

A set of project rules that marks the app’s startup files as protected. These include the Vite HTML entry point, the React bootstrap file, and the package manifest.

In plain words
What is it for?
Use it when working on a Vite and React app to know which files to leave alone, how to add packages with pnpm, and what information to provide when diagnosing build errors.
Why use it?
It helps prevent accidental edits to files that start the app or manage dependencies. When a build fails, it directs troubleshooting toward recent code changes and missing packages.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

protected-files scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Protected Files - Do Not Edit

Never Edit These Files

These are entry points that bootstrap the app. They rarely need changes:

  • index.html - Vite entry point
  • src/ui/main.tsx - React bootstrap
  • package.json - Use pnpm add <package> instead of editing directly

If Build Breaks

Do NOT try to fix config files. Instead:

  1. Check if recent code changes caused the error
  2. Suggest running pnpm install if dependencies are missing
  3. Ask the user to share the full error message
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
