Unquoted `argument-hint: [--global]` parses as a YAML sequence (list containing the single string "--global"). Copilot CLI 1.0.65 requires `argument-hint` to be a string and rejects the sequence, which blocks loading the /init skill. Wrapping the value in double quotes keeps the visible hint identical for users while satisfying the schema.

The bug
skills/init/SKILL.mdhas:YAML parses
[--global]as a flow sequence (a list containing the single string--global), not as a string. Copilot CLI 1.0.65 tightened its frontmatter schema and now requiresargument-hintto be a string — the sequence form fails validation and the/initskill fails to load.The rule is the same as the recently-fixed latent issue in Claude Code proper (anthropics/claude-code#22161): unquoted
[X]in slash-command frontmatter is a YAML array, not a hint string.The fix
Wrap the value in double quotes so YAML treats it as a plain string:
The rendered hint the user sees is identical (
[--global]); only the parse type changes.Scope
