Copilot Skill Naming: Preserve Namespace

What We're Building

Change the Copilot converter to preserve command namespaces when converting commands to skills. Currently workflows:plan flattens to plan, which is too generic and clashes with Copilot's own features in the chat suggestion UI.

Why This Approach

The flattenCommandName function strips everything before the last colon, producing names like plan, review, work that are too generic for Copilot's skill discovery UI. Replacing colons with hyphens (workflows:plan -> workflows-plan) preserves context while staying within valid filename characters.

Key Decisions

• Replace colons with hyphens instead of stripping the prefix: workflows:plan -> workflows-plan
• Copilot only — other converters (Cursor, Droid, etc.) keep their current flattening behavior
• Content transformation too — slash command references in body text also use hyphens: /workflows:plan -> /workflows-plan

Changes Required

1. src/converters/claude-to-copilot.ts — change flattenCommandName to replace colons with hyphens
2. src/converters/claude-to-copilot.ts — update transformContentForCopilot slash command rewriting
3. tests/copilot-converter.test.ts — update affected tests

Next Steps

-> Implement directly (small, well-scoped change)
