Use when writing a use case — a CQRS command handler, a query handler, or its frozen input DTO — including a command that needs compensation, undoing an external write such as an upload when a later store write fails. Owns the command/query split, the read-model versus write-model rule deciding whether a query returns the entity or a row-projected read-model, the try/undo/re-raise compensation body, and a side effect after the store write that never reports a committed command as failed. Not…

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

# Hex — Application

The use-case layer, split by CQRS: **commands** mutate and return an id, **queries** read and return
data. Both are thin — a frozen DTO plus a handler class whose only public method is `execute`.

## When to use vs. neighbours

Command or query → Command or query, at the head of Rules; whether a query returns the entity or a
read-model → Read models, beside it; an undo-on-failure body → Compensation, under Rules, and its template in `COMPENSATION.md`; a notification or other effect after the store write → After the store write, beside it. Outside it:

- A handler writing two or more repositories in one transaction — the unit of work, its protocol and
  the handler form that opens it → `hex-persistence` (`UNIT_OF_WORK.md`).
- The reversing method a compensation calls → declared beside its forward operation by
  `hex-domain-ports`, implemented in `hex-capability-adapter` or `hex-store-repository`.
- The entity, value object or filter record the DTOs mention → `hex-domain-model`.
- The `IFooRepository` a handler depends on → `hex-domain-ports`.
- A rule needing another aggregate's state, which the handler calls rather than inlines → `hex-domain-service`.

How to install

The exact contents, by fingerprint
mdr add wntic/pyhouse/hex-application@sha256:7b298c5166ce6f0f

The line at the top of this page pins the label git:20261014.20fc6e0, 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.
