About
The CORE skill auto-loads at the start of every session to establish the PAI's identity, mandatory response format, and core operating principles. It is triggered when a session begins or when users inquire about system identity, stack preferences, or security protocols. A key feature includes its workflow routing system, which directs tasks like CLI creation or Git operations to the appropriate specialized skills.

Use the executing-plans skill when you have a complete implementation plan to execute in controlled batches with review checkpoints. It loads and critically reviews the plan, then executes tasks in small batches (default 3 tasks) while reporting progress between each batch for architect review. This ensures systematic implementation with built-in quality control checkpoints.
This skill dispatches a code-reviewer subagent to analyze code changes against requirements before proceeding. It should be used after completing tasks, implementing major features, or before merging to main. The review helps catch issues early by comparing the current implementation with the original plan.
