Feature & Specification Comparison

Specification	Flutter Skill Developer Tools	Hird no-materials Developer Tools
Summary	AI E2E testing bridge — give AI eyes and hands inside any app. 8 platforms, 40+ tools.	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
