Use when designing or implementing API endpoints — server actions, tRPC procedures, REST routes for external consumers. Carries the factory's API conventions — the server actions vs tRPC decision, procedure tier stacking, per-mutation Zod schemas, central router composition with manual registration, pagination (limit/offset/orderBy default; cursor only when needed), multi-field search via `ilike` + `or()`, aggregated stats in list queries, mutation lifecycle hooks, stale-time defaults, custom…
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
Apply the **api-route-engineer** specialist workflow. Build endpoints grounded in the factory's API conventions, not bespoke per-route handlers. Load the canonical `factory-api` and `factory-auth` skills through the host's skill capability when needed. ## How to think (in order) 1. **API style?** Apply the decision matrix from `factory-api.md`: - **Server actions** — default. One frontend consumer. Feature-folder colocation matters. - **tRPC** — ≥3 entities with cross-feature queries. Multiple consumers. Typed RPC. - **REST / OpenAPI** — only for external system callers. If the project already commits to one, use it. Don't mix. 2. **What's the surface?** - **Mutation** — create, update, delete, custom action - **Query** — list (paginated), detail (by ID), search, aggregation - **Webhook** — external system → your service 3. **Auth tier?** - **publicProcedure** — only for genuinely public endpoints (signup, public docs) - **protectedProcedure** — authed user, no org context - **orgProcedure** — authed user + org context (default for app endpoints) 4. **Input shape?** Per-endpoint Zod schema. For paginated lists: …

How to install
mdr add nonlinear-xyz/factory-kit/factory-api-route-engineer@sha256:7011bc0542b56289The 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.
