Faber
Your single interface. Breaks the north star into PR-sized issues — one concern each — and drives the loop end to end. Files issues, never code.
Cross-vendor · Autonomous · CI-gated
The workshop where software builds itself.
Fabrica is a small, autonomous coding team. You set the north star; Faber breaks it into PR-sized pieces and debates each with a cross-vendor reviewer, then a coder builds them while a second reviewer checks every change. You stay above the diff.
Coming soon
Being forged in private. A public release is on the way.

CI greenMerge
Two cross-vendor checks — Codex debates the plan, then reviews the code. Revision rounds cap at ~3; genuinely stuck work escalates to a human.
The team
Four roles, two altitudes. You talk to one.
You set the north star and talk only to Faber, the manager. At each altitude, Claude proposes or builds and a different vendor — Codex — checks the work. The reviewers are read-only: they can object, never merge.
Direction
the issue is the message bus
The Debater
Debates each proposal against the north star before any code is written. Proactive work ships only on consensus — veto-only, defaulting to drop.
Delivery
the pull request is the message bus
The Builder
A fresh subagent per issue. Branches, builds, and opens the pull request — then revises it against the review until it converges.
The Reviewer
The cross-vendor second opinion on every change. Comments only — it can object, but it can never merge. CI is the hard gate behind it.
Claude and Codex never talk directly. The issue and the pull request are the message bus.
Why it's built this way
Autonomy that rests on ground truth, not hope.
Cross-vendor by design
Claude proposes and builds; Codex checks — at both altitudes, the plan and the code. Different architectures mean decorrelated blind spots: a reviewer that's valuable because it's another mind, not a second copy.
You stay above the diff
Judgment lives at the direction, not the change. You approve a north star; the team pursues it. You stop reviewing every diff.
CI is the hard gate
Nothing merges unless the tests are green. Ground truth comes first; the diverse reviewer is the second line, not the first.
Safety rails, not trust falls
The reviewer is read-only. Merges are gated and SHA-pinned. Rounds are capped. When the team is stuck, it escalates to a human.
Fabrica is being forged.
The workshop is taking shape. We're still deciding how it ships — check back, and it'll be here.
