Update Skills & Instructions

When a major repository learning is discovered — a recurring pattern, a non-obvious pitfall, a crucial architectural constraint, or domain knowledge that would save future sessions significant time — capture it as a skill or instruction so it persists across sessions.

When to Use

• The user explicitly says "learn!" or asks to capture a learning
• You discover a significant pattern or constraint that cost meaningful debugging time
• You identify reusable domain knowledge that isn't documented anywhere in the repo
• A correction from the user reveals a general principle worth preserving

Decision: Skill vs Instruction vs Learning

Add a learning to an existing instruction when:

• The insight is small (1-4 sentences) and fits naturally into an existing instruction file
• It refines or extends an existing guideline
• Follow the pattern in .github/instructions/learnings.instructions.md
