What is vite-vue3-browser-extension-v3 AGENTS.md?

A set of instructions for AI coding agents working on a Vue 3 and Vite browser extension for Chrome, Firefox, and Edge. It describes the project, commands, coding style, and main folders.

Use it to guide development, testing, linting, formatting, and type checking in the browser-extension codebase.

It gives an agent the project rules and structure it needs before changing code, reducing avoidable mistakes and inconsistent edits.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00725	$0.00725
Opus 5.5	$0.00290	$0.00290
Sonnet 5.5	$0.00145	$0.00145
Haiku 4.5	$0.00072	$0.00072

Security

Grade A, and why

vite-vue3-browser-extension-v3 AGENTS.md 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 2mo 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.

Project Overview

Vue 3 + Vite browser extension (Manifest V3) supporting Chrome, Firefox, and Edge.

Essential Commands

npm run dev:chrome    # Development for Chrome
npm run dev:firefox   # Development for Firefox
npm run build         # Production build for both browsers
npm run lint          # ESLint with auto-fix
npm run typecheck     # TypeScript type checking
npm run format        # Format with Prettier

Code Style

TypeScript: Strict mode enabled. Avoid any type.
Vue: Use <script setup lang="ts"> syntax.
Semicolons: No semicolons (Prettier config).
Quotes: Double quotes (Prettier config).
Trailing commas: Always (Prettier config).
Indentation: 2 spaces, no tabs.
Console: Use console.info, console.warn, or console.error (not console.log).

Architecture

Extension Contexts

src/background/ - Service worker (extension lifecycle)
src/content-script/ - DOM injection, page interaction
src/ui/action-popup/ - Browser action popup
src/ui/options-page/ - Extension options page
src/ui/side-panel/ - Chrome side panel
src/ui/devtools-panel/ - DevTools panel
src/ui/setup/ - Install/update wizard
src/offscreen/ - Offscreen documents

Shared Code

src/components/ - Reusable Vue components
src/composables/ - Vue composables (hooks)
src/stores/ - Pinia state stores
src/utils/ - Utility functions
src/types/ - TypeScript definitions

File-Based Routing

UI pages auto-register from src/ui/<context>/pages/. Create .vue files there to add routes.

Conventions

Components

Use PascalCase for component files: MyComponent.vue
Place shared components in src/components/
Context-specific components stay in their UI folder

Composables

Prefix with use: useTheme.ts, useBrowserStorage.ts
Export functions as named exports

Stores

Suffix with .store.ts: options.store.ts
Use Pinia with Composition API style

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.
