domain-cli SKILL.md skillA
domain-cli from moeru-ai/auv is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add moeru-ai/auv/domain-cli@git:20260725.8a8e541Pins git:20260725.8a8e541 in mdr.lock. Pin the fingerprint instead.

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
# CLI Domain
> **Layer 3: Domain Constraints**
## Domain Constraints → Design Implications
| Domain Rule | Design Constraint | Rust Implication |
|-------------|-------------------|------------------|
| User ergonomics | Clear help, errors | clap derive macros |
| Config precedence | CLI > env > file | Layered config loading |
| Exit codes | Non-zero on error | Proper Result handling |
| Stdout/stderr | Data vs errors | eprintln! for errors |
| Interruptible | Handle Ctrl+C | Signal handling |
---
## Critical Constraints
### User Communication
```
RULE: Errors to stderr, data to stdout
WHY: Pipeable output, scriptability
RUST: eprintln! for errors, println! for data
```
### Configuration Priority
```
RULE: CLI args > env vars > config file > defaults
WHY: User expectation, override capability
RUST: Layered config with clap + figment/config
```
### Exit Codes
```
RULE: Return non-zero on any error
WHY: Script integration, automation
RUST: main() -> Result<(), Error> or explicit exit()
```
---
## Trace Down ↓
From constraints to design (Layer 2):
```
"Need argument parsing"
↓ m05-type-driven: Derive structs for args
↓ clap: #[derive(Parser)]

How to install
mdr add moeru-ai/auv/domain-cli@sha256:82faba357adb435dThe line at the top of this page pins the label git:20260725.8a8e541, 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.
