+# Planning Guidelines
+
+This skill provides guidelines and best practices for project planning and implementation tracking.
+
+## Included Guidelines
+
+### Task Implementation Tracking
+Guidelines for implementing task plans with progressive tracking and change records.
+
+See: [Task Implementation Instructions](../../../instructions/task-implementation.instructions.md)
+
+Key practices:
+- Read and understand the complete plan before starting
+- Process tasks in order, one at a time
+- Track progress in `.copilot-tracking/changes/` files
+- Mark tasks complete as you go
+- Follow existing workspace patterns and conventions
+
+### Specification-Driven Workflow
+A structured approach ensuring requirements are clearly defined, designs are planned, and implementations are documented.
+
+See: [Spec-Driven Workflow v1](../../../instructions/spec-driven-workflow-v1.instructions.md)
+
+Key artifacts to maintain:
+- **`requirements.md`**: User stories and acceptance criteria in EARS notation
+- **`design.md`**: Technical architecture and sequence diagrams
+- **`tasks.md`**: Detailed, trackable implementation plan
+
+## When to Use
+
+Activate these guidelines when:
+- Starting a new feature implementation
+- Breaking down epics into tasks
+- Creating implementation plans
+- Tracking progress on complex work
+- Ensuring documentation stays in sync with code
