Skill Diff

Compare skill versions across CLIs using the skrills MCP server.

Use the `mcp__plugin_skrills_skrills__skill-diff` tool with:

• `name`: Skill name to compare (e.g., "commit", "review-pr")
• `context_lines`: Number of context lines around differences (default: 3)

Parse `$ARGUMENTS` for:

• First positional argument: Skill name (required)
• `--context <n>` or `-C <n>`: Context lines to show

Report comparison results including:

• Which CLIs have the skill
• Unified diff between versions
• Frontmatter differences
• Token count differences
• Whether versions are identical

Handle errors:

• If skill name missing: Prompt for skill name
• If skill not found in any CLI: Report and suggest search command
• If skill exists in only one CLI: Report single-source state
