Session Refiner
About
Session Refiner condenses long technical conversations into a compact markdown summary to reset the context window and reduce token costs. It extracts key decisions, resolved bugs, active tasks, and essential code snippets. Use it at project milestones or when Claude warns the context is getting full to maintain continuity in a fresh session.

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.
