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

miro-diagram 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 today.

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.

What it actually says

Miro Diagram

Shortcut to the Miro MCP diagramming tools.

Explore the diagramming tools exposed by the Miro MCP server and use them according to their tool descriptions and parameter schemas. The MCP server is the source of truth for which diagram types and inputs are supported, which tool to pick, the order in which tools must be called, and all placement parameters.

Workflow

  1. Identify the board URL. If missing, ask.
  2. Identify what to diagram. Ask if unclear.
  3. Pick the appropriate diagramming tool from the Miro MCP server and call it according to its description and parameter schema.

When not to use this skill

If the user wants a brand-new, standalone diagram — not added onto a board they're already working on — use the miro-format skill instead. It creates the diagram as its own content item rather than as a widget.

Changes

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.
