README
Trellis
Engineering process for AI coding agents.
**One source of truth. Inherited by every project. Enforced by hooks. Ready for operator audits.**
*A trellis gives a climbing plant the structure to grow on. This one does the same for code an AI agent writes — without it the work sprawls and breaks; with it, it grows tall and clean.*

Why this exists
The first time you let a coding agent write production code it feels like a superpower. The tenth time, you notice the corners it's been cutting: pushed straight to `main`, marked a task "done" when the tests never ran, summarised what it intended to do instead of what it actually did, force-pushed over an hour of your work to "clean things up."
None of those are bugs in the model. They are gaps in the *process* around the model — the same gaps human teams spent decades closing with branch protection, code review, commit conventions, CI gates, and a thousand small rituals. An agent has none of that scaffolding by default.
**Trellis is that scaffolding, opinionated, in one repo, forkable in ten minutes.**
