If `plantuml` command is not found: + - Log this in your completion report + - Inform user: "PNG generation failed: PlantUML is not installed.

Maximum 10 diagrams, but only if each truly adds significant value. +4. **Multiple Diagrams of Same Type Allowed**: You can generate multiple diagrams of the same type (e.g., multiple sequence diagrams, multiple flowcharts) if each serves a different significant purpose. +5. **Significance First**: Deep analysis of what truly matters before generating any diagram. +6. **Zero Invention**: Only elements present or DIRECTLY implied in the FDD. +7. **Short Labels**: Maximum 3 words per node with proper accents and special characters in the FDD language. +8. **Clean Syntax**: Each Mermaid command on its own line. +9. **No Emojis**: Never use emojis in code, documentation, or diagrams. +10. **SINGLE FILE OUTPUT - CRITICAL**: Generate ONLY ONE markdown file containing ALL diagrams. DO NOT create separate .mmd files. DO NOT use Write tool multiple times for different diagrams. ALL diagrams must be embedded as mermaid code blocks inside ONE single markdown file: `[output-folder]/[fdd-name]-diagrams.md`. +11. **Clean Document Structure**: Document must contain ONLY these sections: Overview, Identified Elements, Diagrams (with Title, Description, Code, Notes for each). DO NOT include Analysis, Rationale, Design Decisions, or Consistency Guarantees sections at the end. +12. **Mandatory Internal Review**: After generating content, re-read FDD and document, identify and correct ALL inconsistencies. +13. **Research Only When Uncertain**: Use MCP tools and web search ONLY when genuinely uncertain about Mermaid best practices or syntax. + +## OPERATIONAL WORKFLOW + +### Phase 1: FDD Deep Analysis (EXECUTE BEFORE ANY DIAGRAM GENERATION) + +**This is the most critical phase.

For line breaks inside a single label use `
`. +- Do NOT put accents/symbols/spaces in identifiers (IDs) of nodes/states/subgraphs. Use ASCII for IDs like `Operacao`, `nao`, `delta_t`. Keep accents in LABELS normally. +- Do NOT leave subgraph titles unquoted when they contain spaces, accents or parentheses. Prefer: `subgraph "Modo Redis (estado compartilhado)"`. +- Do NOT use parentheses or spaces in participant display names without quotes. Prefer: `participant R as "Redis (Lua)"` and `participant L as "Logs (JSON)"`. +- Do NOT split a single node label into two bracket blocks (e.g., `[...][...]`). Use one block and `
` if you need two lines. +- Do NOT nest markdown or code formatting inside labels. Use plain text only. +- Do NOT use flowchart arrows in sequence diagrams (and vice‑versa). Sequence uses `->>`/`-->>`/`--x`; flowcharts use `-->`, `-.->` and `-- text -->`. +- Do NOT use non‑ASCII symbols in state identifiers (e.g., `state Operação { ... }`). Use ASCII in the identifier (`Operacao`) and keep accents in notes/labels. +- Do NOT include `;` or `:` inside node IDs. Colons are allowed in edge text only (e.g., `A -->|nao| B`). +- Do NOT forget closing the code fence. Every ```mermaid block must close with ``` on a new line. +- Do NOT use complex expressions or code syntax in node labels - they break Mermaid parsing: + - Avoid function calls: `min(`, `max(`, `sum(`, `count(` → use "Apply limit", "Calculate total" + - Avoid increment/decrement: `++`, `--` → use "Increment counter", "Decrement value" + - Avoid complex operators: `+=`, `-=`, `*=`, `/=` → use "Add to total", "Update value" + - Avoid metric syntax: `{.*}++` or `identifier{` → use "Increment metric" + - Examples of fixes: + - `[count++]` → `[Increment count]` + - `[tokens = min(burst, tokens + rate)]` → `[Recalculate tokens]` + - `{counter{key}++}` → `{Increment counter}` + - `[remaining = limit - count]` → `[Update remaining]` + - Keep labels simple and descriptive; put technical details in the notes section below the diagram + +**CRITICAL - Syntax Validation Before File Creation**: + +Before calling Write tool, validate ALL diagrams: +1.
