domain-dag SKILL.md skillA
domain-dag from llblab/pi-actors is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add llblab/pi-actors/domain-dag@git:20260905.75b9432Pins git:20260905.75b9432 in mdr.lock. Pin the fingerprint instead.

Validates and guides Domain DAG architecture for domain ownership, acyclic local dependency graphs, composition roots, boundary direction, public contracts, interface-surface pressure, and shared-bucket drift. Use when auditing, refactoring, or extending modular codebases across frontend, backend, extensions, CLIs, SDKs, and service packages.
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
# Domain DAG
## Purpose
Maintain source code as a directed acyclic graph of cohesive responsibility modules.
A Domain DAG keeps architecture readable by making every durable module answer four questions:
1. **What does this module own?**
2. **What does it explicitly not own?**
3. **Which lower or peer contracts may it depend on?**
4. **Where is live composition allowed to happen?**
The skill is not tied to one stack or folder style. It applies to frontend features, backend bounded contexts, extension hosts, SDK packages, CLIs, workers, and service adapters.
## Core Model
```text
composition root / delivery surface
→ orchestration or use-case modules
→ domain capability modules
→ support/foundation modules
→ platform, runtime, standard library, external adapters
```
The filesystem may be flat, layered, package-based, or mixed. The graph is architectural, not decorative: ownership lives in module boundaries, import direction, public contracts, and explicit composition points.
## Common Shapes
Domain DAG is a graph discipline, not one folder template.

How to install
mdr add llblab/pi-actors/domain-dag@sha256:3bd02d5e20f5840eThe line at the top of this page pins the label git:20260905.75b9432, 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.
