Agent Skills

Custom agent skills for Mosaic Stack and USC projects. Platform-aware — works with both GitHub (gh) and Gitea (tea) via our abstraction scripts.

Installation

Via npx (recommended)

Install individual skills into any agent:

# Install a single skill
npx skills add https://git.mosaicstack.dev/mosaic/agent-skills.git --skill pr-reviewer --agent claude-code

# Install all skills
npx skills add https://git.mosaicstack.dev/mosaic/agent-skills.git --agent claude-code

# Non-interactive (CI/scripting)
npx skills add https://git.mosaicstack.dev/mosaic/agent-skills.git --skill pr-reviewer --yes --agent claude-code

Note: The .git suffix on the URL is required for Gitea-hosted repos (forces git clone instead of well-known endpoint discovery).

Manual (symlink from local clone)

Dependencies

• ~/.claude/scripts/git/ — Platform-aware git scripts (detect-platform, pr-view, pr-diff, pr-metadata, pr-review, etc.)
• python3 — For review file generation

Adapting Skills

When adding skills from the community:

1. Replace raw gh/tea calls with our ~/.claude/scripts/git/ scripts
2. Test on both GitHub and Gitea repos
3. Remove features that don't work cross-platform (e.g., GitHub-specific inline comments)
4. Document any platform-specific limitations
