At a glance

A skill your agent uses when building CLI tools. An agent skill from moeru-ai/auv.

Building CLI tools
SKILL.md covers Domain Constraints → Design…, Critical Constraints, Trace Down ↓ and Key Crates, plus 5 more sections
Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
Tasks that involve Secrets management

What it does

Domain CLI is an agent skill from moeru-ai/auv. Use when building CLI tools. Keywords: CLI, command line, terminal, clap, structopt, argument parsing, subcommand, interactive, TUI, ratatui, crossterm, indicatif, progress bar, colored output, shell completion, config file, environment variable, 命令行, 终端应用, 参数解析

Its SKILL.md is about 990 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Secrets management. The repository describes itself as: 📱🐭 No we are not computer use, it's Application Use Via... a unified orchestration layer of OS automation, 0 token cost. The licence is Apache-2.0.

When your agent uses it

Building CLI tools
Tasks that involve Secrets management

Example prompts

“/domain-cli”

What it can do on your machine

Read from SKILL.md and the folder at commit 4042350. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are rust).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Domain CLI loads about 988 tokens when it runs. Until then it costs about 68 tokens; SKILL.md has 209 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~68
When it runs · the whole SKILL.md, loaded when a task matches: ~988

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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)]

"Need config layering"
    ↓ m09-domain: Config as domain object
    ↓ figment/config: Layer sources

"Need progress display"
    ↓ m12-lifecycle: Progress bar as RAII
    ↓ indicatif: ProgressBar

Key Crates

Purpose	Crate
Argument parsing	clap
Interactive prompts	dialoguer
Progress bars	indicatif
Colored output	colored
Terminal UI	ratatui
Terminal control	crossterm
Console utilities	console

Design Patterns

Pattern	Purpose	Implementation
Args struct	Type-safe args	`#[derive(Parser)]`
Subcommands	Command hierarchy	`#[derive(Subcommand)]`
Config layers	Override precedence	CLI > env > file
Progress	User feedback	`ProgressBar::new(len)`

Code Pattern: CLI Structure

rust

use clap::{Parser, Subcommand};

#[derive(Parser)]
#[command(name = "myapp", about = "My CLI tool")]
struct Cli {
    /// Enable verbose output
    #[arg(short, long)]
    verbose: bool,

    #[command(subcommand)]
    command: Commands,
}

#[derive(Subcommand)]
enum Commands {
    /// Initialize a new project
    Init { name: String },
    /// Run the application
    Run {
        #[arg(short, long)]
        port: Option<u16>,
    },
}

fn main() -> anyhow::Result<()> {
    let cli = Cli::parse();
    match cli.command {
        Commands::Init { name } => init_project(&name)?,
        Commands::Run { port } => run_server(port.unwrap_or(8080))?,
    }
    Ok(())
}

Common Mistakes

Mistake	Domain Violation	Fix
Errors to stdout	Breaks piping	eprintln!
No help text	Poor UX	#[arg(help = "...")]
Panic on error	Bad exit code	Result + proper handling
No progress for long ops	User uncertainty	indicatif
