You'd call it a project.
Favur calls it a favor.

It catches its own mistakes mid-run, with no one steering — a team of agents that plans, builds, reviews, and ships a finished repo on its own.

Why Favur

Why Favur

The favor you don't babysit.

Most favors come with strings — check in, nudge, keep it pointed. Not this one. Favur scores its own agents, catches its own slip-ups, and steers itself back on track. Ask once, walk away.

No shortcuts, however small the favor.

Trivial task or serious project, every run gets the same lifecycle — architecture, sprints, review, tests. Favur doesn't skip steps when the favor looks easy.

Staff it however you like.

Agents can each run on a different model — cheap ones on the boilerplate, frontier ones on the judgment calls — all in a single run.

How the favor gets done.

It reads the ask.

Commits to an architecture and records its decisions before a line of code exists.

It plans the work.

Breaks the favor into sprints and writes pseudocode before building.

It writes the code — and doesn't trust itself.

One agent writes, a separate reviewer checks the diff against the plan, a tester proves it.

It ships.

Dependencies installed, build green, tests passing, sprint reviewed; a complete, tested repository.

Every decision is written down as it goes — which is why you can replay a whole run below and watch it happen.
