Kaixn
kaixn turns your team's architecture and product decisions into a living source of truth that is mined from your code, governed by your team, and read by your agents.
Core trick
Mines architecture decisions from the codebase into a team-governed document, then diffs each PR against it to surface implied decisions.
Description
kaixn turns your team's architecture and product decisions into a living source of truth that is mined from your code, governed by your team, and read by your agents.
Humans should review design decisions that matter - not code that agents write.
README excerpt
<div align="center"> <img src="assets/logo-lockup.svg" alt="kaixn" width="200"> <p><i>Review the decision, not the diff.</i></p> </div> kaixn moves code review **up the stack** for everyone who touches a codebase. Today PMs write specs disconnected from the system's truth, and engineers review agent-generated *code* line by line — the wrong altitude in a world where agents write the code. kaixn owns a **living constitution** of a team's engineering principles, decisions, and patterns, and surfaces it at the two moments that matter: - **PMs** write intent → kaixn shows the **engineering blast radius** and the *gaps* (the paths they didn't know) before any code is written. - **Engineers** review the **constitutional delta a PR implies** — which patterns it introduces or evolves, and what it leaves incomplete — instead of the diff. - **Agents** read the constitution to know what to follow, and feed learnings back. Three first-class users: **PM, EM, and agents.** ## Rigor for free The constitution isn't something you author from scratch. kaixn ships a **pre-built, industry-standard catalog of engineering axes** — point it at any repo and it inherits that rigor immediately. The codified concepts are what we bring to the table: *you don't define them — they're industry standard.* We play **above the language layer**. Naming, formatting, type-hints, lint rules are table stakes that coding agents and linters already own. kaixn governs the **design & architecture** tier
