cmdop-skill 2026.3.5.3

Build and publish CMDOP skills

cmdop-skill

Build and publish CMDOP skills.

Install

pip install cmdop-skill

Quick Start

Create a new skill (scaffold wizard)

cmdop-skill init

Interactive wizard: name (with PyPI availability check), description, author. Category, tags, and visibility are determined automatically by the server during publish.

Or write one from scratch

from cmdop_skill import Skill, Arg

skill = Skill()  # name, version, description from pyproject.toml

@skill.command
async def greet(name: str = Arg(help="Who to greet", required=True)) -> dict:
    """Say hello."""
    return {"message": f"Hello, {name}!"}

if __name__ == "__main__":
    skill.run()

Skill() and SkillConfig() auto-resolve name, version, description from the nearest pyproject.toml. Explicit arguments still win:

skill = Skill(name="override-name")  # only name overridden, rest from pyproject.toml

Framework Features

• @skill.command — turn async/sync functions into CLI subcommands
• Arg() — declarative arguments with help, required, default, choices, nargs, action
• @skill.setup / @skill.teardown — lifecycle hooks
• TestClient — test harness for skills (client.run() and client.run_cli())
• pyproject.toml as single source of truth — name, version, description auto-resolved; no duplication
• Auto src/ path — src/ is added to sys.path automatically
• JSON output — all commands return {"ok": true, ...} by default

CLI Commands

Command	Description
init [path]	Scaffold a new skill project (interactive wizard)
install <path>	Symlink skill into system skills directory
uninstall <name>	Remove skill from system skills directory
run <path> <prompt>	Run skill via cmdop SDK
test <path>	Run pytest in skill directory
bump [path]	Bump version in pyproject.toml (semver)
check-name <name>	Check if package name is available on PyPI
release [path]	Bump + build + upload to PyPI + publish to CMDOP
publish	Publish skill to the CMDOP marketplace
list	List your published skills
config set-key	Save API key globally
config show	Show saved config (key masked)
config reset	Remove saved API key

init

cmdop-skill init                        # scaffold in current directory
cmdop-skill init ./skills               # scaffold in ./skills/

Also available programmatically:

from cmdop_skill.scaffold import ScaffoldConfig, scaffold_skill

config = ScaffoldConfig(name="my-skill", description="Does things")
files = scaffold_skill(config, target_dir=Path("."))

config

API key is resolved in order: --api-key flag > CMDOP_API_KEY env > saved config > interactive prompt.

cmdop-skill config set-key              # interactive (masked input)
cmdop-skill config set-key cmdop_xxx    # direct
cmdop-skill config show
cmdop-skill config reset

On auth errors (401/403), the CLI prompts for a new key and saves it automatically.

install / uninstall

cmdop-skill install ./skills/my-skill
# Installed my-skill -> ~/Library/Application Support/cmdop/skills/my-skill (symlink)

cmdop-skill uninstall my-skill

bump

cmdop-skill bump                        # patch: 0.1.0 -> 0.1.1
cmdop-skill bump --minor                # minor: 0.1.1 -> 0.2.0
cmdop-skill bump --major                # major: 0.2.0 -> 1.0.0

check-name

cmdop-skill check-name my-cool-skill
# my-cool-skill is available on PyPI

cmdop-skill check-name requests
# requests is taken on PyPI

release

cmdop-skill release                     # bump patch + build + PyPI + CMDOP
cmdop-skill release -b minor            # bump minor
cmdop-skill release --no-bump           # current version
cmdop-skill release --test-pypi         # TestPyPI only (skips CMDOP)
cmdop-skill release --no-publish        # PyPI only (skips CMDOP)

Publish

Only the skill name is required to create a skill on the marketplace. Everything else is automatic:

• Category — determined by the server from manifest keywords
• Tags — extracted from pyproject.toml keywords
• Description — from README / pyproject.toml
• Repository URL — from pyproject.toml
• Visibility — public by default
• Translations — generated server-side via LLM

cmdop-skill publish --path .            # publish to prod
cmdop-skill publish --mode local        # publish to localhost:8000
cmdop-skill publish --json              # CI mode (no interactive prompts)

skill/config.py — minimal manifest:

from cmdop_skill import SkillConfig

config = SkillConfig()

All metadata (name, version, description) is auto-resolved from pyproject.toml. Category, tags, and visibility are determined automatically by the server during publish.
