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 | $0.00323 | $0.00323 |
| Opus 5.5 | $0.00129 | $0.00129 |
| Sonnet 5.5 | $0.00065 | $0.00065 |
| Haiku 4.5 | $0.00032 | $0.00032 |
Grade C, and why
lucid-mcp-server copilot-instructions.md scanned grade C with 1 finding 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.
Hidden instructionshighPrompt injection
Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

This is an MCP Server project for Lucid App (Lucidchart/LucidSpark) integration.
- Always try to get documentation for API that your trying to use, do following: read documentation => write code => test it. If you did something else inbeetween, read documentation again.
- Try to use context7 tool to get documentation for libraries and APIs, if doesn't provide enough information, use web search.
- Always write tests for your code and measure code coverage, desired code coverage is 80% for all new code.
- Maintain test pyramids, prefer unit/component tests over integration tests.
- Prefer updating existing files over creating new ones.
- Keep the codebase clean and maintainable.
- Keep the code modular and testable.
- Simplicity is key, avoid unnecessary complexity.
- If you going to add new code always make sure that the old one is not broken by your change and still needed.
- Don't write unnecessary comments and documentation if not asked
- Use the @modelcontextprotocol/sdk for all MCP protocol logic.
- Don't use emojis in code, comments or documentation.
- Use stdio transport for server communication.
- You can find more info and examples at https://modelcontextprotocol.io/llms-full.txt
- For Lucid API integration, refer to https://developer.lucid.co/
- All documentation and comments must be in English.
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.
