cli-developer skillA
cli-developer is agent-read markdown (skill) from jahidulislamseo/antigravity-ai-skills: Use when building CLI tools, implementing argument parsing, or adding interactive prompts. Invoke for parsing flags and subcommands, displaying progress bars and spinners, generating bash/zsh/fish completion scripts, CLI design, shell completions, and cross-platform terminal applications using commander, click, typer, or cobra..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# CLI Developer ## Core Workflow 1. **Analyze UX** — Identify user workflows, command hierarchy, common tasks. Validate by listing all commands and their expected `--help` output before writing code. 2. **Design commands** — Plan subcommands, flags, arguments, configuration. Confirm flag naming is consistent and no existing signatures are broken. 3. **Implement** — Build with the appropriate CLI framework for the language (see Reference Guide below). After wiring up commands, run `<cli> --help` to verify help text renders correctly and `<cli> --version` to confirm version output. 4. **Polish** — Add completions, help text, error messages, progress indicators. Verify TTY detection for color output and graceful SIGINT handling. 5. **Test** — Run cross-platform smoke tests; benchmark startup time (target: <50ms). ## Reference Guide Load detailed guidance based on context: | Topic | Reference | Load When | |-------|-----------|-----------| | Design Patterns | `references/design-patterns.md` | Subcommands, flags, config, architecture | | Node.js CLIs | `references/node-cli.md` | commander, yargs, inquirer, chalk | …
