Score: 5.0/10 (Innovation: 6, Technical: 4, Documentation: 2, Utility: 5)

SpecDeck is a specification management tool for coding agents, using a git-like workflow (main, branches, pull requests) to track decisions agents make during implementation. It aims to keep specs as living documents by having agents propose changes back to the spec, which humans review and publish. The project is early-stage with minimal documentation and an MCP-based integration.

Target audience: backend developers, engineering teams using coding agents
