Problem

When executing workflows with Codex CLI, skills from global/user-scope directories (e.g., ~/.copilot/skills/time-greeting) fail to copy with ENOENT error.

Current Behavior

1. Add a skill from ~/.copilot/skills/time-greeting to workflow
2. Click "Execute with Codex CLI"
3. ❌ Error: Failed to copy skill "time-greeting": ENOENT: no such file or directory, scandir '{project}/.copilot/skills/time-greeting'

The checkSkillsToNormalize() function was reconstructing the source path using getSourceSkillsDir(), which always returns project-scope paths. This caused user-scope skill paths to be incorrectly resolved.

Expected Behavior

1. Add a skill from any scope (user or project) to workflow
2. Click "Execute with Codex CLI"
3. ✅ Skill is correctly copied from its actual location to .claude/skills/

Solution

Use path.resolve(workspaceRoot, path.dirname(skillPath)) to derive the source directory directly from the skill's actual path.

Changes

File: src/extension/services/skill-normalization-service.ts

• Replace getSourceSkillsDir() call with path.resolve(workspaceRoot, path.dirname(skillPath))
• path.resolve() correctly handles:
  • Absolute paths (user-scope): Returns path as-is
  • Relative paths (project-scope): Resolves against workspaceRoot
• Mark unused _getSourceSkillsDir() with underscore prefix for future use

Impact

• Fixes skill normalization for user-scope skills (~/.copilot/skills/, ~/.codex/skills/)
• Fixes skill normalization for project-scope relative paths (.github/skills/)
• No breaking changes
• Windows compatible (verified path.resolve() handles both separators)

Testing

• Manual E2E: Global skill (~/.copilot/skills/) → Codex CLI execution
• Manual E2E: Project skill (.github/skills/) → Codex CLI execution
• Build passes (npm run check && npm run build)
• Windows compatibility verified (code review)
