retro private skills

Reflect reusable learnings from a session, incident, diff, error, or prompt into the user's private skill repository. The default output is a focused change under the private repo's .github/skills/<skill>/ tree. Do not convert these learnings into personal instructions, prompts, memories, agents, workspace files, or public sync output.

When to Use

• User says: private skill retro, private skill repo, skill repo authoring, private skill fix, retro private skills, /retro-private-skills
• User provides Learnings / Evidence / Impact and wants them reflected into reusable Skill behavior
• User wants to create or update private repo SKILL.md / references/*
• A prior attempt wrote to ~/.copilot/instructions, copilot-instructions.md, VS Code User Data prompts, or local .copilot skills, and the user wants the private repo Skill version instead
