messages-api skillA
messages-api is agent-read markdown (skill) from air-gapped/skills: Reference for the Anthropic Messages API (/v1/messages) as a third-party compatibility protocol — the 7 inference servers that implement it natively (vLLM, SGLang, llama.cpp, Ollama, mistral.rs, Llama Stack/OGX, Lemonade), gateways that adapt it (LiteLLM, Bifrost, Superagent Gateway), client behavior (Claude Code, opencode anthropic provider), Messages ↔ Chat Completions translation, the thinking-signature seam, stop_reason divergences, and streaming quirks. NOT for official Anthropic API usage .
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
How to install
mdr add air-gapped/skills/messages-api@git:20260725.aef8f18mdr add air-gapped/skills/messages-api@sha256:72aca37dec0868cfPin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
