API conventions for both server actions and tRPC builds. Covers the decision between them, per-mutation Zod input schemas, central router composition, pagination shape, multi-field search via Drizzle `ilike` + `or()`, mutation lifecycle hooks, conditional query enabling, stale-time defaults, error response shape and custom error class taxonomy, mutation-boundary audit logging, fetch adapter for tRPC routes. Read when designing or implementing any data-mutation endpoint.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Factory api Each section leads with **Principle** (one sentence, stack-agnostic), then **Why** (constraint → option → tradeoff), then **Recipe** (the Next.js / Drizzle / tRPC shape we use), and **Failure mode** when there's one to name. Sections that are pure style with no deeper truth are marked `Recipe only`. Editors: if the Principle could appear unchanged in *Clean Code*, sharpen the Why with a Factory-specific observation or drop the section to Recipe only — honesty over inflation. ## API style — pick one **Principle.** Pick one transport style per project; don't mix server actions and tRPC. **Why.** Two transport styles in one codebase means two error-handling conventions, two cache-invalidation patterns, two surfaces to audit. The cost compounds linearly with every new endpoint; the cleanup is almost never worth the disruption. The decision is cheap at project start and expensive six months in. **Recipe.** | Style | Pick when | |---|---| | **Server actions** | Default. Feature-folder colocation matters. One frontend consumer. App-internal API only. Pairs with TanStack Query `useMutation`. | …

How to install
mdr add nonlinear-xyz/factory-kit/factory-api@sha256:9822a0fe7381e8abThe line at the top of this page pins the label git:20260716.517fb94, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
