Show HN: ArchDocs – Shared context and verification for engineers and AI agents

ArchDocs is a tool that connects design docs, architecture decisions, implementation plans and recorded work so that engineers and coding agents work from the same plan, with agents accessing specs and open questions over MCP. It compares planned changes against recorded changes and GitHub pull requests and checks to surface gaps in both directions, and keeps a work log with handoffs for resuming tasks. The Free plan includes architecture docs, MCP access and one design doc, with unlimited design docs on Team and reviews, approvals and GitHub evidence on Business and Enterprise.
