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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00047 | $0.00721 |
| Opus 5 | $0.00023 | $0.00360 |
| Sonnet 5 | $0.00009 | $0.00144 |
| Haiku 4.5 | $0.00005 | $0.00072 |
Grade A, and why
houdini-cli 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.
How it starts
The opening of the file, as written. The whole thing — 53 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Houdini CLI
This skill provides the ability to interact with Houdini's command-line tools.
Environment Setup
Before running any Houdini tool, you must first locate the Houdini installation path and its bin directory.
-
Locate Houdini: Use the
houdini-locatorskill to obtain the install path (HFS) and bin directory (HBIN). -
Run a tool: Prefix the tool name with the HBIN path, e.g. in PowerShell use
& "<HBIN>\ginfo.exe" <args>.
Common Workflows
Inspect Geometry
Use ginfo to inspect geometry files such as .bgeo, .bgeo.sc, and .obj.
- Example:
& "<HBIN>\ginfo.exe" -v my_geo.bgeo.sc
Convert Geometry Formats
Use gconvert to convert files between different formats.
- Example:
& "<HBIN>\gconvert.exe" input.bgeo.sc output.obj
Render HIP Files
Use hrender for batch rendering.
- Example:
& "<HBIN>\hrender.exe" -d /out/mantra1 -f 1 -e 10 myscene.hip
USD Render with husk
Use husk to render a .usd/.usda/.usdc stage via a Hydra delegate (Karma by default).
- Example:
& "<HBIN>\husk.exe" --make-output-path -f 1 -n 10 -o /render/out.$F4.exr scene.usd(-n 10= frame count, renders frames 1–10) - Pick a delegate with
-R(e.g.-R HdArnoldRendererPlugin) and a specificRenderSettingswith--settings /Render/rendersettings. - See husk.md for the full flag list (frame range, output overrides, purpose/complexity, verbosity, threading, etc.).
USD Preview Render with usdrecord
Use usdrecord for quick USD previews via Pixar's reference USD renderer (Storm by default; Karma CPU/XPU and Houdini GL also available). Invoke through hython so Houdini's libraries load correctly.
- Example:
& "<HBIN>\hython.exe" "<HBIN>\usdrecord" --renderer Storm -w 1280 scene.usd preview.png - Sequences require a frame placeholder in the output path (e.g.
out.####.exr) and--frames 1:100. - See usdrecord.md for the full flag list and troubleshooting.
Run Python Scripts
Use hython to run scripts with access to the hou module.
- Example:
& "<HBIN>\hython.exe" process_geo.py
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.
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.
- 5d ago First seen · 53 lines · 47 tokens per session scan A 704d6e7f162b
houdini-cli is a skill published in the GitHub repository chordee/houdini-tools (5 stars, last pushed 6d ago), licensed MIT. It adds 47 tokens to every session and 721 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 2026-08-31.
