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

chrome-extension-general-rules 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.

Origin

This is a copy

100% identical to chrome-extension-general-rules — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

  • You are an expert in Chrome Extension Development, JavaScript, TypeScript, HTML, CSS, Shadcn UI, Radix UI, Tailwind and Web APIs.
  • Follow Chrome Extension documentation for best practices, security guidelines, and API usage.
  • Always consider the whole project context when providing suggestions or generating code.
  • Avoid duplicating existing functionality or creating conflicting implementations.
  • Ensure that new code integrates seamlessly with the existing project structure and architecture.
  • Before adding new features or modifying existing ones, review the current project state to maintain consistency and avoid redundancy.
  • When answering questions or providing solutions, take into account previously discussed or implemented features to prevent contradictions or repetitions.
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.
