A living constitution for your codebase

Agents write the code.
You govern the decisions.

kaixn mines your codebase into a versioned record of the architecture and product decisions behind it. Your team ratifies the rules, and your agents build from them.

The shift

Code got cheap. Judgment didn't.

When agents write most of the code, volume stops being the bottleneck. The real risk is code that quietly diverges from the architecture and product decisions your team already made.

Review moves up the stack. The question is no longer “is this line correct?” but “does this honor the decision we made?” That judgment is the part that didn’t get cheap.

How it works

Three surfaces. One source of truth.

The same governed handbook, seen from three sides. Intent, review, and execution finally point at one place.

Product & eng leaders

Declare intent

A PM writes plain-language intent. kaixn turns it into a typed proposal checked against your constitution, and surfaces the paths a change touches before engineering starts.

Engineers

Review the decision, not the diff

When a PR lands, kaixn shows which architectural patterns it introduces or evolves, and what it leaves incomplete. You review the constitutional delta instead of the line diff.

Coding agents

Build from the same truth

Committed proposals become grounded agent contracts. Over MCP, agents read your norms, get pattern guidance, and submit changes back through a gated path.

The loop

A loop that keeps the truth alive.

Decisions flow through the work and come back stronger each cycle.

1
Mine

kaixn reads code, docs, and ADRs into candidate norms.

2
Ratify

Your team promotes the norms worth committing to.

3
Propose

Intent becomes a typed, conflict-checked proposal.

4
Review

Each PR is checked for drift against governed norms.

5
Feed back

Learnings return through a gated, provenance-tracked path.

Rigor for free

Point it at a repo. Inherit the discipline.

kaixn mines your codebase and its history to surface the architecture decisions already implicit in it, then holds new work to that standard.

  • Decisions mined from real code and review history. Your conventions are captured as they already exist.
  • Conventions and invariants are told apart automatically. Enforcement fits each decision.
  • Held to on every pull request and governed by your team.
  • A pre-built, 168-axis catalog across twelve categories. Rigor is there on day one.
Boundaries

Where kaixn focuses.

Architecture and design

kaixn governs layering, seams, dependency injection, error handling, trust boundaries, and concurrency. It owns the decisions, and your agents write the code.

Engineering discipline

Testing strategy, PR hygiene, and security practices live as governed norms your team ratifies and evolves.

A living constitution

Decisions are mined from your code, conflict-checked as typed proposals, and committed with full provenance. They stay current instead of going stale.
