Coding agents can write code. Keeping the work reviewable is the hard part. gentle-pi is a Pi-native development harness for builders using coding agents on real repositories. It helps you put structure around agent work by adding Spec-Driven Development workflows, focused subagents, test evidence, and review guardrails. Key features: • SDD/OpenSpec workflow – installs phase agents and chains from exploration and proposal through apply, verify, and archive • Focused subagents – keeps one parent session responsible while child agents explore, implement, test, or review with focused context • Strict TDD support – records RED → GREEN → TRIANGULATE → REFACTOR evidence when a project declares a test command • Work routing discipline – keeps small tasks inline while sending large or risky changes through SDD/OpenSpec • Project/user skill discovery – brings project and user skills into the workflow instead of leaving them buried in the repo It’s open-source (MIT license).
