Quality Metadata

Every installable registry entry may include a quality object. TARS renders this metadata in the Extensions Hub before install:

• score: required when quality is present; integer from 0 to 100.
• last_updated: ISO date (YYYY-MM-DD) for the packaged entry metadata or files.
• tests_passing: whether the latest maintainer smoke/unit test pass is known.
• required_tools: local executables or CLIs the package expects.
• permissions: user-impacting capabilities such as filesystem, github, network, browser, or mcp.
• companion_cli: whether the skill ships or depends on a companion CLI/script.
• install_count: optional observed install count when available.

Domain Packs

packs are reviewable bundles of existing skills, plugins, and MCP packages. TARS prints the install plan before applying it, then installs each member through the same sandbox checks as individual package installs.

Contributing

1. Create skills/<your-skill>/SKILL.md
2. Or create mcp-servers/<your-server>/tars.mcp.json plus hosted runtime files
3. Or create a packs entry that references existing packages
4. Add an entry to registry.json with quality metadata
5. Open a PR

OpenClaw Compatibility

TARS can also install skills from ClawHub via adapter. Use the --source openclaw flag:

tars skill search --source openclaw <query>
tars skill install --source openclaw <package-name>
