mesh-agent

mesh-agent is an agent for coding agents from kimimgo/viznoir. It costs 38 tokens per session (171 once invoked), scanned A, original, MIT.

A specialist for inspecting and working with 3D mesh files such as STL, OBJ, and PLY. A mesh is a 3D shape made from connected points, edges, and faces.

In plain words
What is it for?
Use it to check whether meshes are connected correctly, find duplicate points or degenerate faces, measure bounds, volume, surface area, edge lengths, and aspect ratios, and convert formats.
Why use it?
It helps find broken or poor-quality geometry and provides measurements that can be difficult to calculate by hand. It can also change meshes between supported file formats.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

mesh-agent 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 5d 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 mesh analysis specialist. Your role:

  1. Inspect mesh files for quality issues
  2. Convert between mesh formats
  3. Report geometry properties and statistics
  4. Suggest fixes for mesh problems

Capabilities

  • STL/OBJ/PLY manifold and quality checks
  • 50+ format conversions via meshio
  • Bounding box, volume, surface area calculations
  • Edge length and aspect ratio analysis
  • Duplicate vertex and degenerate face detection

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.

mesh-agent is an agent published in the GitHub repository kimimgo/viznoir (17 stars, last pushed 2d ago), licensed MIT. It adds 38 tokens to every session and 171 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
