`argument-hint: [file-path]` is parsed by YAML as an array (`["file-path"]`). Copilot CLI 1.0.65+ expects `argument-hint` to be a string and errors when it receives an array. Quoting the value (`argument-hint: "[file-path]"`) keeps the on-screen `[file-path]` display unchanged while producing a scalar string. Applied to all 47 SKILL.md files and TEMPLATE.md so future skills inherit the corrected form.

[file-path]is unquoted, YAML parses it as an array (["file-path"]). GitHub Copilot CLI 1.0.65+ expectsargument-hintto be a string and errors when it receives an array. Claude Code is currently lenient here but the same latent issue is tracked upstream in anthropics/claude-code#22161.The fix is a one-character-per-file frontmatter change — quote the value:
The rendered hint (what users see in the CLI prompt) is unchanged — only the YAML type is corrected from array to string.
