houdini-scripting

houdini-scripting is a skill for Claude Code from dcc-mcp/dcc-mcp-houdini. It costs 51 tokens per session (484 once invoked), scanned A, original, MIT.

A support skill for running Python inside Houdini, a 3D graphics and visual-effects application, through its own Python environment. It also checks the Houdini session and project file when needed.

In plain words
What is it for?
Use it to inspect the Houdini version, project path, and interface availability, or to run one-off Python automation in Houdini.
Why use it?
It provides a way to automate Houdini when no more specific scene-editing tool is available, while recognizing that scripts can change the open scene.

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

houdini-scripting 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 10d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/execute_python.py, scripts/get_session_info.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

houdini-scripting

Escape hatch for arbitrary Python in Houdini. Skills-first: call typed tools from other skills before execute_python.

When to use

  • Confirm Houdini version, hip path, and UI availability → get_session_info
  • One-off automation with no typed tool yet → execute_python

Safety

  • All tools run on the main thread (affinity: main).
  • execute_python can mutate the scene; treat as destructive.
Files

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
