Decide where a piece of processing (especially a write / state change) should be implemented in a web system: as a synchronous GraphQL / REST API operation, or as a renchan-job-bullmq background worker triggered from an API handler, from a post-worker after the response, or on a schedule. Use this skill whenever the user is turning a requirement into an implementation and needs to choose the execution location, including where an external-integration write belongs.

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

# Execution Placement Pattern (deciding where processing lives)

A skill for deciding, the moment you receive a requirement, **where that processing should be
implemented**. Before diving into the implementation details (how to write the job, how to write the
resolver, etc.), first lock down the "placement". Once the placement is decided, you can hand it off
to the individual implementation skills (`hor-renchan-job-bullmq`, etc.).

## Grand principle: write processing lives in only two places — "API" or "Worker"

In a web system, **processing that changes state (writes)** only ever happens in one of two places.
Every requirement must resolve into this binary choice. The deciding axis is **how heavy / how
long-running the processing is**.

| Placement | Execution model | What it holds |
| --- | --- | --- |
| **API** | Responds **synchronously** to the request | Things that are **light and finish quickly** |
| **Worker** | Runs **asynchronously** in the background | Things that are **heavy and take time** |

- **Why only two places**: a write can only originate from "an external request (API)" or "processing

How to install

The exact contents, by fingerprint
mdr add openreachtech/hora-skills-ort-renchan/hor-execution-placement-pattern@sha256:85f8939c30cc5771

The line at the top of this page pins the label git:20260905.5a04969, 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.
