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 | $0.00700 | $0.00700 |
| Opus 5.5 | $0.00280 | $0.00280 |
| Sonnet 5.5 | $0.00140 | $0.00140 |
| Haiku 4.5 | $0.00070 | $0.00070 |
Grade A, and why
raindrop-mcp 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 1mo 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 & AI Assistant Instructions
General Coding Principles
- Write modular, well-documented, and maintainable code.
- Use modern, type-safe, idiomatic TypeScript. Prefer interfaces for object types and camelCase/PascalCase naming conventions.
- Use zod for schema validation where appropriate.
- Use async/await for all asynchronous code.
- Group imports by type (external, then internal).
- Use try/catch for error handling with descriptive messages.
- Prefer explicitness and reference documentation or example repos if ambiguous.
Raindrop.io & MCP API Coverage
- Ensure complete coverage for Raindrop.io and MCP endpoints.
- Reference Raindrop.io API docs for endpoints, authentication, and data models.
- Reference
raindropio/appfor implementation details and usage patterns. - LLM friendly documentation is
https://context7.com/context7/developer_raindrop_io/llms.txt - Reference Model Context Protocol docs and LLMs integration guide for MCP compliance.
- Reference MCP TypeScript SDK for usage patterns.
Project Structure
- Source:
src/ - Build:
build/ - Tests:
tests/(all test files must be here)
Development Best Practices
- Structure tools with clear schemas, validation, and consistent JSON responses.
- Include documentation and setup instructions.
- Use design patterns for maintainability and scalability.
- Use helper functions to reduce duplication.
- Prefer declarative programming styles and common libraries/utilities.
- Use
bunfor package management/scripts (not npm).
Testing
- Use Vitest for all tests.
- Validate tool calls return properly structured responses.
- Verify manifest loads and host integration works.
Tooling & References
- For debugging MCP servers, see MCP Debugging Instructions.
- Use Inspector tool and repo for protocol inspection.
- Use
#concept7for documentation access and reference for SDKs, APIs, and protocol details. - MCP Protocol spec: specification
- MCP server examples:

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.
