What it does
CLI Developer is an agent skill from sundial-org/awesome-openclaw-skills. Use when building CLI tools, implementing argument parsing, or adding interactive prompts. Invoke for CLI design, argument parsing, interactive prompts, progress indicators, shell completions.
Its SKILL.md is about 890 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files (for example `references/design-patterns.md`, `references/go-cli.md` and `references/node-cli.md`).
It works with Python. The repository describes itself as: Top OpenClaw skills, with the most popular and useful ones.
When your agent uses it
- Building CLI tools
- Implementing argument parsing
- Adding interactive prompts
Example prompts
- “/cli-developer”
Requirements
- Python 3
- Node.js
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Analyze UX - Identify user workflows, command hierarchy, common tasks
- Design commands - Plan subcommands, flags, arguments, configuration
- Implement - Build with appropriate CLI framework for the language
- Polish - Add completions, help text, error messages, progress indicators
- Test - Cross-platform testing, performance benchmarks
What it can do on your machine
Read from SKILL.md and the folder at commit b80cde2. 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.
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
CLI Developer loads about 890 tokens when it runs, and up to ~12k if it reads all its reference files. Until then it costs about 52 tokens; SKILL.md has 369 words of instructions outside code blocks.
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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 369 words (~890 tokens).
“Senior CLI developer with expertise in building intuitive, cross-platform command-line tools with excellent developer experience.”
