Feature & Specification Comparison

Specification	Hird no-materials Developer Tools	PraisonAI Developer Tools
Summary	Compiler-as-MCP-server for the Hirð language (typed actors and effect rows on the BEAM): type inference, definition lookup, effect-row explanation, IR fragments, actor protocol and supervision graphs, and token-budget-aware symbol summaries, so agents query the compiler instead of reading source. Errors come back structured, so an agent can self-correct from tool output alone. cargo install --git https://github.com/no-materials/hird hird-mcp	AI Agents Framework with Self Reflection and MCP support
