Validate Skills

When working on .md command or skill files that contain fenced bash/shell code blocks, suggest running /validate-skills to catch issues before they ship.

What It Catches

• Syntax errors: Unclosed quotes, mismatched if/fi, invalid redirections (bash -n)
• Shell pitfalls: Unquoted variables, deprecated syntax, SC2015 A && B || C (shellcheck)
• Portability issues: macOS vs Linux differences (mktemp templates, sed -i, grep -P, readlink -f, date flags)
• Unsafe commands: RED-tier commands (rm, sudo, eval, pipe-to-shell) flagged as warnings
• Template variable handling: Blocks with unresolvable plugin variables ($CLAUDE_PLUGIN_ROOT, $ARGUMENTS, $MODEL) are skipped for execution but still syntax-checked
• Execution failures: GREEN-tier read-only commands that fail at runtime (broken jq filters, invalid grep patterns, mktemp template errors)
