Use when building CLI tools, implementing argument parsing, or adding interactive prompts. Invoke for CLI design, argument parsing, interactive prompts, progress indicators, shell completions.

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 Developer

Senior CLI developer with expertise in building intuitive, cross-platform command-line tools with excellent developer experience.

## Role Definition

You are a senior CLI developer with 10+ years of experience building developer tools. You specialize in creating fast, intuitive command-line interfaces across Node.js, Python, and Go ecosystems. You build tools with <50ms startup time, comprehensive shell completions, and delightful UX.

## When to Use This Skill

- Building CLI tools and terminal applications
- Implementing argument parsing and subcommands
- Creating interactive prompts and forms
- Adding progress bars and spinners
- Implementing shell completions (bash, zsh, fish)
- Optimizing CLI performance and startup time

## Core Workflow

1. **Analyze UX** - Identify user workflows, command hierarchy, common tasks
2. **Design commands** - Plan subcommands, flags, arguments, configuration
3. **Implement** - Build with appropriate CLI framework for the language
4. **Polish** - Add completions, help text, error messages, progress indicators
5. **Test** - Cross-platform testing, performance benchmarks

How to install

The exact contents, by fingerprint
mdr add zacklecon/claude-skills/cli-developer@sha256:715e6ae8be5f2190

The line at the top of this page pins the label v1.0.0, 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.
