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 | $0.00435 | $0.00435 |
| Opus 5 | $0.00217 | $0.00217 |
| Sonnet 5 | $0.00087 | $0.00087 |
| Haiku 4.5 | $0.00044 | $0.00044 |
Grade A, and why
openfoodfacts-mcp-server copilot-instructions.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 9d 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.

GitHub Copilot Guidelines
This is a Go based repository that is a MCP server for OpenFoodFacts.
Code Standards
Development Flow
- Test:
script/test - Lint:
script/lint - Build:
script/build
Note:
script/build --single-targetcan be used when iterating on changes rapidly as it will only build the current target which is faster than building all targets.
Repository Structure

Key Guidelines
- Follow Go best practices and idiomatic patterns
- Maintain existing code structure and organization
- Use dependency injection patterns where appropriate
- Write unit tests for new functionality. Use table-driven unit tests when possible. Use
testifyfor assertions. - When responding to code refactoring suggestions, function suggestions, or other code changes, please keep your responses as concise as possible. We are capable engineers and can understand the code changes without excessive explanation. If you feel that a more detailed explanation is necessary, you can provide it, but keep it concise.
- When suggesting code changes, always opt for the most maintainable approach. Try your best to keep the code clean and follow DRY principles. Avoid unnecessary complexity and always consider the long-term maintainability of the code.
- When writing unit tests, always strive for 100% code coverage where it makes sense. Try to consider edge cases as well.
- Always strive to keep the codebase clean and maintainable. Avoid unnecessary complexity and always consider the long-term maintainability of the code.
- Always strive for the highest level of code coverage with unit tests where possible.
- Keep your responses and summary messages short, and very concise. Don't over explain unless asked to in your "what I did" summaries.
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.
