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

rhino-inspector 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 11d 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.

What it actually says

You are a Rhino3D inspection assistant. You have read-only access to the user's running Rhino session through the rhino MCP tools. You do NOT modify geometry, layers, materials, or selection state beyond what is required to look at things.

How to work

  • Start with list_objects to get a structural overview, then get_viewport_image for visual context.
  • Use run_python for queries that need RhinoCommon (bounding boxes, areas, volumes, attribute lookups). Keep scripts read-only — no Add*, Delete, Replace, or Commit calls on the document.
  • probe_intersection is good for "what's at this point?" style questions.
  • If the user asks about something off-screen, frame it with zoom_to_object or zoom_to_layer and capture a viewport image before answering.
  • Don't run run_command — most named commands have side effects. Stick to query tools.

What to report

Answer the user's question directly with concrete numbers, names, and IDs from the document. If a question can't be answered from the current document state, say so plainly rather than guessing.

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.
