Coterie › How it works

How a multi-agent coding workflow runs in Coterie.

Coterie is a Windows app that coordinates Claude Code, Codex and Antigravity on one project. An architect plans, developers build in parallel, a different model reviews, you test the result and decide what merges. Here is each step.

STEP 1

Connect your tools

Coterie finds the official CLIs you already use and checks that they are signed in, through their own sign-in windows. It reads their real usage limits. It never reads or stores their credentials.

STEP 2

The architect plans

You write the goal in plain words. The architect reads the code and proposes small tasks, each with acceptance criteria, the files it may touch and what it waits for. Nothing starts until you confirm the plan.

PLAN · Folio · 3 tasks · 2 shifts

Book layoutshift 1

Content engineshift 1

Render and flipwaits for 2

STEP 3

Developers build in parallel

Each task runs in its own git worktree, so agents never overwrite each other and your main branch stays untouched. Tasks that do not wait for each other start together, on whichever CLI still has room.

STEP 4

A different model reviews

When a task is done, Coterie runs your project’s own checks on the exact files, then a model from another provider reviews the diff against the criteria. Missing evidence is reported as missing, never as approved.

Codex · Lunaapproved

npm test · 12/12 · typecheck · passed

STEP 5

Test the result

When a goal is complete, “Test the result” opens the finished project in a separate window, served from a read-only copy with the network blocked. You try it like a user, without rebuilding anything by hand.

STEP 6

You decide what merges

What needs you is the lit star on the map. Read the report, look at the changes, approve and merge, or send it back with a note.

Autonomy

Choose how much you hand over, per project.

Manual shifts

You start each shift of tasks and approve every merge.

Ask me only before merging

Confirming the plan starts the work. You approve each merge.

Run and merge automatically

Changes merge only after passing checks and complete reviews. You can pause or stop at any time.

Per project

Different models for different roles, per project.

Each role has its own ordered list of models, and each project can use its own. Rules, limits and spending caps are set per project too.

Let the agents work. Keep the last word.

Join the beta and be among the first to run Coterie on your own repository: plan, parallel build, cross-review, test the result, merge.
