+description: Generate Mermaid diagrams from a Feature Design Document (FDD). Usage: /generate-mermaid <path-to-fdd.md> [output-folder]
+---
+
+You MUST invoke the mermaid-diagram-generator agent using the Task tool with subagent_type="mermaid-diagram-generator".
+
+Extract the FDD file path and optional output folder from the command arguments:
+- FDD file path (required)
+- Output folder (optional, default: "docs/mermaid")
+
+Pass the following detailed prompt to the agent:
+
+"Generate Mermaid diagrams from the Feature Design Document located at [FDD_FILE_PATH].
+
+Output folder: [OUTPUT_FOLDER]
+
+The agent will execute its complete workflow (Phases 1-9). Your task is to ensure the agent receives the correct FDD path and output folder.
+
+Key requirements the agent will follow:
+
+ANALYSIS & SELECTION:
+- Read FDD completely and detect language (Portuguese, English, Spanish, etc.)
+- Extract explicit elements and identify what is central to system success
+- Evaluate significance rigorously using 5 criteria (main flow, difficult parts, architectural decisions, public contracts, relationships)
+- Select appropriate diagram types (Sequence, Flowchart TD/LR, Class, ER)
+- Prune to most valuable diagrams (typical: 6-8, up to 10 maximum if truly justified)
+
+GENERATION:
+- Create ONE markdown file: [OUTPUT_FOLDER]/[feature-name]-diagrams.md
+- Translate ALL section headers to FDD language with proper accents
+- Keep technical terms in English (Service, Gateway, Redis, etc.)
+- Write concise paragraphs (3-5 sentences) for each diagram
+- Use concise labels (3 words max per node)
+- Use proper accents EVERYWHERE (markdown text AND diagram node labels)
+- Apply Mermaid syntax validation and guardrails automatically
+
+QUALITY ASSURANCE:
+- Mandatory internal review: re-read FDD and document, identify and correct ALL inconsistencies
+- Validate: language matches FDD, 1-10 diagrams (typical: 6-8), significance criteria met, no redundancy/fabrication/excluded items
+- Create self-contained complete file
+- Report: detected language, file path, number of diagrams, rationale, validation results
+
+CRITICAL RULES:
+- Never invent information not in the FDD
+- Generate diagrams in FDD language with proper accents EVERYWHERE
+- Better 6 excellent diagrams than 10 mediocre ones
+- Mandatory internal review before completion
+- Keep technical terms in English
+- No emojis anywhere
+- Use proper accents in node labels (Mermaid supports UTF-8)
+- Keep node labels simple; avoid complex expressions
+- Put technical details in notes section below diagram, not in labels
+- The agent handles all syntax validation and guardrails automatically"
+
+Replace [FDD_FILE_PATH] with the actual file path from command arguments.
+Replace [OUTPUT_FOLDER] with the specified output folder or "docs/mermaid" if not provided.
+Replace [feature-name] with the appropriate feature name extracted from the FDD filename (e.g., "ratelimiter" from "ratelimiter-fdd.md").
