Skills fail to load in GitHub Copilot CLI ≥1.0.65 due to array-shaped `argument-hint`

[thejesh23]

Bug

argument-hint in the YAML frontmatter of 6 SKILL/command file(s) is declared with bare brackets (a YAML flow sequence), so downstream slash-command loaders that validate argument-hint as a string — notably GitHub Copilot CLI ≥ 1.0.65 — silently reject the SKILL on load. The command disappears from the CLI menu.

# Broken (parses as an array of one string)
argument-hint: [<version>]

# Fixed (parses as a string)
argument-hint: "[<version>]"

Claude Code currently renders the accidental array by concatenation, which is why nobody caught this until Copilot CLI tightened the type check. Both Claude Code slash-command docs and VS Code Agent Skills docs document argument-hint as a string.

Fix

Wrap the value after argument-hint: in double quotes. One-character change per line, no behaviour change on Claude Code.
