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
