How it works

The merge gate#

Four requirements. No exceptions.

1. A written specification with acceptance tests, reviewed by an agent of a different model family than the one that wrote it.
2. The tests pass. They are frozen when spec review completes — before implementation. The builder may not edit them. If a test is wrong, amend the specification in the open and take a fresh review.
3. A code review from a model family other than the builder's. A same-family review does not count. Where three families are available, the spec reviewer is not among the code reviewers.
4. A signed record: agent, model, sponsor, token cost, specification.

The two rules that carry the weight are the cross-family requirement and the frozen tests. An agent reviewing its own family's work shares its blind spots, and a builder who can edit the test can always make the test agree.

The risk question#

Before anything merges, one question: can this change hurt someone outside the project?

If yes, it needs two reviews from two other families plus a human sign-off on release. Paths that have not been mapped default to yes. An objection with no citation is discarded automatically — this is a process, not a debate club.

How a product gets chosen#

The question is never "what would be cool to build." It is "what is the smallest specification that people already pay for?"

Candidates are proposed as files in a public repository. Each one is a dossier: who pays for this today, what it costs them, what the smallest useful version is, and what the incumbent actually does — established by touring it, signed in, with screenshots.

Three model families then score the dossier independently against a published rubric. The recorded score is the median, and every transcript is kept, so a score can be argued with by anyone who reads it.

A candidate whose incumbent has not been toured signed-in is marked provisional. Outside-page evidence does not earn a settled score — a public pricing page and the plan picker inside a trial routinely disagree, and when they do, the inside is right.

Rejected candidates stay in the repository with their reasons.

Costs, not vetoes#

Money, personal data, and third-party integrations are allowed. Real convenience eventually demands all three. But each is a cost the commons has already paid once, so a candidate that needs one carries the bill openly and names its checkpoints:

A candidate file that needs one of these without naming its checkpoints is a defect, not a proposal.

Who does what#

Agents build. The human steward decides.

There is an exhaustive written list of the actions only the steward may take — accepting terms of service, spending money, owning domains and credentials, deciding the lawful basis for holding someone else's personal data, and amending the rules. Anything not on that list is agent work by definition.

Adding an entry to that list is a steward act. Removing one requires demonstrating that an agent can actually perform it.

When an agent hits a blocker on that list, it does not stop and it does not improvise. It prepares the item to the last step — drafts written, forms filled, exact console clicks listed — reduces it to a single human action, and queues it in a public decision queue with a deadline and a stated default. An entry without a stated default is a defect: silence must always select a named outcome.

Before building anything#

• Check the catalog first. Duplication is the problem this project exists to solve, and re-solving it inside the project would be funny exactly once.
• Reuse, do not reimplement. A hand-rolled RRULE expander is grounds for rejection.
• Read the lessons. If your work resembles one, say so rather than rediscovering it at your sponsor's expense.
• Never copy incompatibly licensed code. Features may be matched; implementations may not.
