Create Cli
Design command-line interface parameters and UX: arguments, flags, subcommands, help text, output formats, error messages, exit codes, prompts, config/env precedence, and safe/dry-run behavior. Use when you’re designing a CLI spec (before implementation) or refactoring an existing CLI’s surface area for consistency, composability, and discoverability.
Choose how to use this skill
You do not need every option. Choose the path your AI client supports. The stable page stays the same; versioned files are immutable.
1. Native installer
This listing has no registered native installer command. Use the complete package or source fallback below, depending on what your client supports.
Do not guess an installer command or replace an existing version without reviewing the diff.
2. Complete package recommended
Download the ZIP when available. It includes SKILL.md plus the references, security notes and version metadata.
No complete ProSkills package is published for this listing yet.3. Prompt-only
Copy the prompt above when the agent can read the stable page or when you want to adopt the workflow without installing a skill.
Need only the instruction file?
Download SKILL.md only if your client requires a single file. The complete ZIP is safer for a full installation because it preserves the references and release context.
No path installs or executes anything by itself. Your agent still needs access to the project files. Before updating, compare the installed version and review the diff.

Create CLI
Design CLI surface area (syntax + behavior), human-first, script-friendly.
Do This First
Read agent-scripts/skills/create-cli/references/cli-guidelines.md and apply it as the default rubric.
Upstream/full guidelines: https://clig.dev/ (propose changes: https://github.com/cli-guidelines/cli-guidelines)
Ask only the minimum clarifying questions needed to lock the interface.
Clarify (fast)
Ask, then proceed with best-guess defaults if user is unsure:
Command name + one-sentence purpose.
Primary user: humans, scripts, or both.
Input sources: args vs stdin; files vs URLs; secrets (never via flags).
Output contract: human text, --json , --plain , exit codes.
Interactivity: prompts allowed? need --no-input ? confirmations for destructive ops?
Config model: flags/env/config-file; precedence; XDG vs repo-local.
Platform/runtime constraints: macOS/Linux/Windows; single binary vs runtime.
Deliverables (what to output)
When designing a CLI, produce a compact spec the user can implement:
Command tree + USAGE synopsis.
Args/flags table (types, defaults, required/optional, examples).
Subcommand semantics (what each does; idempotence; state changes).
Output rules: stdout vs stderr; TTY detection; --json /--plain ; --quiet /--verbose .
Error + exit code map (top failure modes).
Safety rules: --dry-run , confirmations, --force , --no-input .
Config/env rules + precedence (flags > env > project config > user config > system).
Shell completion story (if relevant): install/discoverability; generation command or bundled scripts.
5–10 example invocations (common flows; include piped/stdin examples).
Default Conventions (unless user says otherwise)
-h/--help always shows help and ignores other args.
--version prints version to stdout.
Primary data to stdout; diagnostics/errors to stderr.
Add --json for machine output; consider --plain for stable line-based text.
Prompts only when stdin is a TTY; --no-input disables prompts.
Destructive operations: interactive confirmation + non-interactive requires --force or explicit --confirm=... .
Respect NO_COLOR , TERM=dumb ; provide --no-color .
Handle Ctrl-C: exit fast; bounded cleanup; be crash-only when possible.
Templates (copy into your answer)
CLI spec skeleton
Fill these sections, drop anything irrelevant:
Name: mycmd
One-liner: ...
USAGE:
mycmd [global flags] [args]
Subcommands:
mycmd init ...
mycmd run ...
Global flags:
-h, --help
--version
-q, --quiet / -v, --verbose (define exactly)
--json / --plain (if applicable)
I/O contract:
stdout:
stderr:
Exit codes:
0 success
1 generic failure
2 invalid usage (parse/validation)
(add command-specific codes only when actually useful)
Env/config:
env vars:
config file path + precedence:
Examples:
…
Notes
Prefer recommending a parsing library (language-specific) only when asked; otherwise keep this skill language-agnostic.
If the request is “design parameters”, do not drift into implementation.
