PSG - Project State Graph

An installable runtime, MCP server, and portable Agent Skill that gives coding agents persistent task, mutation, review, and completion boundaries. It binds verification to the current worktree, preserves project decisions, blocks unauthorized edits, and ends review at a deterministic SHIPPABLE gate.

Evidence

116 collected tests, Windows, macOS, and Linux CI across Python 3.10 and 3.13, seven versioned releases with checksums, deterministic boundary and mechanics benchmarks, and a published research evaluation plan. The historical agentic A/B result is retained but explicitly marked superseded.

This is a lightweight page for sharing. The full, interactive version lives in the terminal portfolio.
