CC Plugins

Core development workflow plugins for Claude Code with specialized agents, Task tool orchestration, and architecture skills.

Overview

CC Plugins provides 6 plugins with 10 specialized agents, 7 commands, and 19 skills covering software development workflows and certification exam preparation.

Bugfix and feature-development plugins use Claude Code Agent Teams for iterative do-loops (doer+critic pairs). Requires CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1.

All agents use YAML frontmatter for proper Claude Code registration and are callable via Task(subagent_type="plugin:agent").
