Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions subagents; mentions AGENTS.md; mentions Codex.

This is Malnati/vaults-diagram-tools's own configuration. It tells Codex and OpenCode how to work on vaults-diagram-tools itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything vaults-diagram-tools configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

vaults-diagram-tools AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Escopo operacional

Este repositório é o pacote standalone vaults-diagram-tools, extraído para concentrar ferramentas portáveis de diagramas Mermaid, diagramas derivados de código-fonte e MCP.

Use este repositório para:

  • Renderizar fontes Mermaid para artefatos .svg e .jpg.
  • Gerar diagramas Mermaid a partir de árvores de código-fonte.
  • Expor as ferramentas de diagramação por MCP stdio.
  • Validar a política Markdown de diagramas.

Mantenha este repositório limitado ao tooling portável de diagramas; fluxos de conteúdo externo ficam fora do escopo operacional deste pacote.

Artefatos de agentes identificados no projeto

Codex

  • AGENTS.md: orientação operacional do projeto para agentes.

Cursor

  • .cursor/rules/mermaid-renderer-tooling.mdc
  • .cursor/rules/source-diagrams-tooling.mdc
  • .cursor/skills/mermaid-renderer-tooling.md
  • .cursor/skills/source-diagrams-tooling.md
  • .cursor/hooks.json: superfície explícita sem hooks configurados.

Tooling real do repositório

  • vaults-mermaid-render: CLI pública para renderização Mermaid.
  • vaults-source-diagrams: CLI pública para geração de diagramas a partir de código-fonte.
  • vaults-diagram-mcp: servidor MCP stdio do pacote.
  • vaults-markdown-diagram-policy: checker da política Markdown de diagramas.
  • packages/renderer/render-mermaid-assets.mjs: implementação principal do renderer.
  • packages/renderer/render-mermaid-assets.sh: wrapper de compatibilidade do renderer.
  • packages/renderer/check-markdown-diagram-policy.py: implementação do checker Markdown.
  • packages/source-diagrams/source-diagrams.mjs: implementação principal do gerador source-diagrams.
  • packages/mcp/server.mjs: servidor MCP.
  • packages/mcp/tools.mjs: adaptação MCP para os CLIs reais.

Regras obrigatórias

  1. Ao renderizar Mermaid, cada fonte .mmd ou .mermaid deve gerar .svg e .jpg no mesmo ciclo.
  2. Em Markdown, exibir o código Mermaid em bloco cercado com linguagem mermaid; não usar mmd como linguagem do bloco.
  3. Em Markdown, manter .mmd, .svg e .jpg como links relativos; não embutir SVG/JPEG com sintaxe de imagem por padrão.
  4. Usar vaults-mermaid-render ou packages/renderer/render-mermaid-assets.mjs para renderização canônica.
  5. Usar vaults-source-diagrams ou packages/source-diagrams/source-diagrams.mjs para diagramas derivados de código-fonte.
  6. Para fluxos MCP, manter a superfície explícita de três tools: render_mermaid_text, render_mermaid_file, generate_source_diagrams.
  7. Para lógica e testes rápidos de source-diagrams, usar --render-mode placeholder quando a fidelidade visual não estiver em escopo.
  8. Para entrega real de assets, usar renderização canônica e validar presença de .mmd, .svg, .jpg e manifest quando aplicável.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
