 # Contributing to Builder
 
-Builder turns an idea into approved documents, a design and a working web app:
-a coordinator agent talks with the person and hands work to specialist agents,
-on a hub built on vendored Interchange. What it is and why is in
-[PRODUCT.md](https://github.com/corbitsdev/corbits-builder/blob/main/docs/PRODUCT.md),
-how it is structured in
-[ARCHITECTURE.md](https://github.com/corbitsdev/corbits-builder/blob/main/docs/ARCHITECTURE.md),
-and the concrete choices, layout and Interchange docs map in
-[IMPLEMENTATION.md](https://github.com/corbitsdev/corbits-builder/blob/main/docs/IMPLEMENTATION.md).
-Running it is in
-[DEV.md](https://github.com/corbitsdev/corbits-builder/blob/main/docs/DEV.md),

-These conventions apply to every change, whoever or whatever writes it.
 
-- Every dependency is pinned to an exact version: no `^`, `~`, ranges or
-  `latest`.
-- Interchange's packages (`@intx/*`) are meant to be used. Import them by
-  package name wherever they fit; the interface talks to the hub through
-  `@corbits-builder/client`. Build on Interchange's agent loop, retries, waits, timeouts, mail,
-  approvals and failure handling rather than reimplementing them, and read the
-  area's Interchange doc first.
+The scripts in
+[CONTRIBUTING.md](https://github.com/corbitsdev/corbits-builder/blob/main/CONTRIBUTING.md#making-a-change)
+and the
+[Corbits Triage policy](https://github.com/corbitsdev/corbits-builder/blob/main/.corbits-triage.yml)
+enforce most code conventions; run them before saying the tree passes.
+These are the ones no check catches:
+
+- Build on Interchange's agent loop, retries, waits, timeouts, mail, approvals
+  and failure handling rather than reimplementing them, and read the area's
+  Interchange doc first.
+- The interface talks to the hub through `@corbits-builder/client`.
 - A change to `vendor/interchange` is its own `(vendor)` commit that also
-  updates `vendor/interchange.manifest.json`; `bun run vendor:verify` fails on
-  anything unrecorded.
+  updates `vendor/interchange.manifest.json`.
 - User-visible wording lives in configuration: `apps/hub/src/config/` for the
   hub and agents, `apps/web/src/config.ts` for the interface.
 - Secrets stay out of responses, logs, documents and prompts; the interface
   shows only whether a secret is set.
-- Comments explain why, not what the code already says.
-- `bun run check` is the gate: lint (oxlint), format (`bun fmt`), typecheck and
-  tests. Run it before saying the tree passes.
 - Conventional Commits (`<type>(<scope>): <description>`), one logical change
   per commit and per pull request.
+- Comments explain why, not what the code already says.
 - Prompts describe the task and the domain. Turn order, reply termination and
   loop detection are the inference loop's job.
