Copilot CLI 1.0.65 fails to load slash commands whose YAML frontmatter has an unquoted argument-hint value starting with '['. YAML parses the value as a flow sequence (array), but Copilot expects a string, so the skill silently fails to register. Wrap the affected argument-hint values in double quotes so YAML parses them as strings. Affects spike, stats, and trace skills.

Summary
Copilot CLI 1.0.65 fails to load slash commands whose YAML frontmatter has an unquoted
argument-hintvalue beginning with[. YAML parses the value as a flow sequence (array), but Copilot CLI expects a string, so the affected skills silently fail to register.Three plugin skills currently trip this:
plugin/skills/spike/SKILL.md—argument-hint: [duration like 1h, 4h, 1d — default 1h]plugin/skills/stats/SKILL.md—argument-hint: [period]plugin/skills/trace/SKILL.md—argument-hint: [endpoint | trace-id]The fix wraps each value in double quotes so YAML parses it as a string. Behavior for users on older Copilot CLI versions and for Claude Code is unchanged (the display text is identical); this just makes the frontmatter conform to Copilot CLI 1.0.65's stricter type check.
