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

claude-desktop-extension 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 6d 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

I want to build this as a Desktop Extension, abbreviated as "DXT". Please follow these steps:

  1. Read the specifications thoroughly:

  2. Create a proper extension structure:

    • Generate a valid manifest.json following the MANIFEST.md spec
    • Implement an MCP server using @modelcontextprotocol/sdk with proper tool definitions
    • Include proper error handling and timeout management
  3. Follow best development practices:

    • Implement proper MCP protocol communication via stdio transport
    • Structure tools with clear schemas, validation, and consistent JSON responses
    • Make use of the fact that this extension will be running locally
    • Add appropriate logging and debugging capabilities
    • Include proper documentation and setup instructions
  4. Test considerations:

    • Validate that all tool calls return properly structured responses
    • Verify manifest loads correctly and host integration works

Generate complete, production-ready code that can be immediately tested. Focus on defensive programming, clear error messages, and following the exact DXT specifications to ensure compatibility with the ecosystem.

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.
