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 | $0.02789 | $0.02789 |
| Opus 5 | $0.01394 | $0.01394 |
| Sonnet 5 | $0.00558 | $0.00558 |
| Haiku 4.5 | $0.00279 | $0.00279 |
Grade A, and why
swagger-mcp-adapter 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 7d 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 Instructions for Swagger MCP Adapter
Project Overview
This is a TypeScript-based MCP (Model Context Protocol) server that integrates with Swagger/OpenAPI specifications to expose API endpoints as tools for Large Language Models (LLMs). The project provides a seamless way to connect existing REST APIs to LLMs, allowing them to make requests and receive responses through standardized MCP commands.
The server reads Swagger/OpenAPI files, parses the endpoints, and exposes them as MCP tools that LLMs can invoke. This enables LLMs to interact with your APIs in a structured, validated manner.

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.
