Score: 7.3/10 (Innovation: 7, Technical: 7, Documentation: 8, Utility: 7)

Theta-spec is a declarative, harness-agnostic configuration standard for AI coding agents, allowing a single `theta.toml` file to define instructions, rules, tools, skills, and subagents across multiple agent harnesses. It addresses the fragmentation of agent configuration formats by providing a unified manifest with a clear lifecycle protocol. The project is innovative for combining concepts from build systems and dependency management into the AI agent tooling space, with solid documentation and a practical Rust CLI reference implementation.

Target audience: backend devs, AI/ML engineers, devops
