Universal Message Format (UMF) - Provider-agnostic message representation for LLM interactions with ChatML formatting, internal hub model, and MCP support
The autonomous, self-improving AI agent. Single Rust binary. Every channel. Install with: cargo install opencrabs
Typed fluent builder for Anthropic Messages-API content blocks (text, image, tool_use, tool_result, document). Emits the exact JSON shape the API expects. No SDK dependency.
Parse Anthropic's Server-Sent Events stream into typed events. No SDK dependency — feed it bytes, get back message_start, content_block_delta, etc.
Approximate token counts for LLM messages, system prompts, and tools. Zero-config chars/4 heuristic, BYO tokenizer, content-block aware (text/image/tool_use/tool_result/document). One serde_json dep.
OpenAI-compatible API proxy backed by GitHub Copilot
