Headless browser automation CLI optimized for AI agents. Uses snapshot + refs system for 93% less context overhead vs Playwright. Purpose-built for web testing, form automation, screenshots, and data extraction.
Manage a gitflow branching workflow — starting and finishing feature, release, and hotfix branches; cutting versioned releases with changelog generation; coordinating emergency hotfixes directly to production; and keeping long-lived branches in sync. Activates when users mention gitflow, feature/release/hotfix branches, cutting a release, branching strategy, promoting an integration branch to production, tagging a version, or rolling back a live release. Also reaches for it when the user says "ship it", "promote dev to main", or "we need to hotfix prod" without naming gitflow. Skip for general git mechanics (commit messages, merge conflicts, interactive rebase, git education) or CI-failure debugging unrelated to a release.
Fixes a bug through test-driven debugging — reproduces it with a failing test, locates the root cause with evidence (file:line), then applies the smallest fix that resolves it without refactoring unrelated code. Use when the user wants to fix a bug, debug an issue, resolve an error, or investigate a failing test. Not for building new functionality (use implement-feature) or restructuring working code with no bug involved (use refactor).
Implements a new feature end-to-end as a senior staff engineer would — discovers project conventions, researches current best practices, drafts a plan for approval, then builds it with parallel subagents that reuse existing code, skip speculative abstractions, and verify with tests before completion. Use when the user wants to implement, build, add, or ship new functionality (a feature, endpoint, component, module, or integration) — not for fixing an existing bug (use fix-bug) or restructuring code that already works (use refactor).
Restructures existing code without changing its behavior — maps callers and test coverage, adds characterization tests where coverage is thin, then applies the change in small steps verified against the full test suite after each one. Use when the user wants to refactor, extract a method or class, simplify logic, reduce duplication, improve naming, restructure modules, or pay down technical debt in code that already works. Not for adding new functionality (use implement-feature) or fixing broken behavior (use fix-bug).
Runs a comprehensive multi-agent code review of a PR, commit, or the whole codebase across six dimensions (correctness, performance, code style, test coverage, error handling, and simplicity/over-engineering) and returns a severity-ranked report with file:line findings and fix suggestions. Use when the user wants a thorough code review, asks to review a PR or diff, or wants over-engineered code flagged for simplification. Analysis only, identifying issues without modifying code, committing, or running tests. Not for a security-focused audit (use review-security) or a visual/UX design critique (use review-design).

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.
# Interactive fuzzy search across skills.sh
npx skills find
# Search by keyword
npx skills find typescript
npx skills find react
npx skills find testing
# List skills in a repository without installing
npx skills add owner/repo --list
# Example: list Vercel's official skills
npx skills add vercel-labs/agent-skills --list
# Example: list Anthropic's skills
npx skills add anthropics/skills --list
# Interactive installation (choose skills and target agents)
npx skills add owner/repo
# Install a specific skill for Claude Code
npx skills add owner/repo --skill skill-name -a claude-code
# Install globally (available across all projects)
npx skills add owner/repo --skill skill-name -a claude-code -g
# Install all skills from a repo to all detected agents
npx skills add owner/repo --all
| Command | Purpose |
|---|---|
npx skills find [query] | Search skills.sh directory |
npx skills add <source> | Install skills from a repository |
npx skills list | View installed skills |
npx skills check | Check for available updates |
npx skills update | Update all installed skills |
npx skills remove [name] | Uninstall a skill |
npx skills init [name] | Create a new skill template |
Project scope (default): Installs to .claude/skills/ in the current project directory. Committed with the project and shared with team members.
Global scope (-g flag): Installs to ~/.claude/skills/ in the home directory. Available across all projects for the current user.
Recommendation: Install domain-specific skills (e.g., a framework skill) at project scope. Install general-purpose skills (e.g., code review, testing patterns) at global scope.
The add command accepts multiple source formats:
# GitHub shorthand (most common)
npx skills add owner/repo
# Full GitHub URL
npx skills add https://github.com/owner/repo
# Direct path to a specific skill
npx skills add https://github.com/owner/repo/tree/main/skills/skill-name
# GitLab URL
npx skills add https://gitlab.com/org/repo
# Local directory (for development)
npx skills add ./my-local-skills
