CAVEATS

Dependencies

Requires `resources/implementation-playbook.md` when detailed examples needed

Missing context

Format or structure of the user-provided diagram request or data
Target rendering environment or Mermaid version

Ambiguities

The instruction 'If detailed examples are required, open `resources/implementation-playbook.md`' references an external file without specifying its availability or content.
'Use this skill when' and 'Do not use this skill when' sections introduce meta-agent logic that may conflict with direct use as a standalone prompt.

IMPROVEMENT SUGGESTIONS

Remove or clearly separate the meta 'Use this skill when' / 'Do not use this skill when' blocks so the prompt can be used directly without an agent framework.
Add an explicit input section describing the expected user request format (e.g., 'User will provide: description of system, entities, or process to visualize').

USAGE

Copy the prompt above and paste it into your AI of choice — Claude, ChatGPT, Gemini, or anywhere else you're working. Replace any placeholder sections with your own context, then ask for the output.
