Discover and install third-party agent skills from the open Agent Skills ecosystem powered by skills.sh.
Creates isolated Git worktrees for feature branches with prioritized directory selection, gitignore safety checks, auto project setup for Node/Python/Rust/Go, and baseline verification.
Executes implementation plans in current session by dispatching fresh subagents per independent task, with two-stage reviews: spec compliance then code quality.
Dispatches parallel agents to independently tackle 2+ tasks like separate test failures or subsystems without shared state or dependencies.
Discover and install third-party agent skills from the open Agent Skills ecosystem powered by skills.sh.
The Agent Skills format is an open standard for packaging procedural knowledge, workflows, and tools that AI agents load on demand. The npx skills CLI (maintained by Vercel Labs) serves as "npm for AI agents" -- enabling discovery and installation of community skills from any Git repository.
skills.sh is the public directory and leaderboard for the ecosystem, hosting thousands of skills across categories like frontend, backend, DevOps, and more.
Before installing third-party skills, note that cc-arsenal already provides:
Only install external skills that provide capabilities not already covered above.
