frontend

A set of project rules for frontend JavaScript work. Frontend code runs in the part of a website that users see and interact with.

In plain words
What is it for?
Use it when building or editing frontend features. It specifies Tailwind CSS, mobile-first layouts, existing components and dependencies, Prettier and lint settings, naming conventions, braces for if statements, and PNPM with fixed dependency versions.
Why use it?
It keeps new code consistent with the project’s styling, naming, formatting, dependency, and package-management choices.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

frontend 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 yesterday.

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

Frontend & Javasccript

  • Use Tailwind CSS for styling.
  • Follow mobile-first responsive design.
  • Avoid CSS-in-JS solutions (e.g., Emotion).
  • When creating a frontend based on an uploaded image, be as close to the original as possible and double check the styling so it matches the image exactly.
  • Use the installed dependencies over introducing something new.
  • Use existing components from the (mono)repo.
  • Use Prettier & Lint configurations from the (mono)repo to ensure consistent code style and best practices.
  • For if statements, always use braces, even for single-line blocks.
  • Use the installed dependencies over introducing something new.

Naming Conventions

  • Directories/Files: Use lowercase with dashes (e.g., components/auth-wizard).
  • Components: Favor named exports.

Package Manager

  • Use PNPM
  • Use fixed versions for dependencies
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.
