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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00026 | $0.00392 |
| Opus 5 | $0.00013 | $0.00196 |
| Sonnet 5 | $0.00005 | $0.00078 |
| Haiku 4.5 | $0.00003 | $0.00039 |
Grade A, and why
Houdini 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 8d 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.
This is a copy
84% identical to Audition — 16 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
This skill lets a coding agent operate SideFX Houdini on the desktop through Flue, a local shell-to-application bridge. The agent pipes Python into houdini_bridge.py and gets structured JSON back.
agent shell ->
houdini_bridge.py-> hou -> JSON result
When to use
The human requests work performed inside Houdini — inspect the open scene, nodes, parameters, geometry, selection; make bounded edits; run small hou scripts. A CLI agent cannot act inside Houdini without a bridge like Flue.
How to proceed
- Read
FLUE.mdin this directory first. It explains how Flue works, the bridge contract, a workedhouexample, and safety expectations. - If Flue is installed: also read
C:\Users\fredd\.claude\skills\flue\SKILL.mdandadapters/houdini_adapter/APP.mdfor the operational contract, then work from there. - If Flue is not installed: tell the human. The install command is
pip install flue && flue setup. Do not install without explicit approval in the current session.
Other apps
Flue also supports Photoshop, Illustrator, Premiere, After Effects, InDesign, Audition, Blender, 3ds Max, Unity, and Microsoft Office through the same stdin/stdout contract. One install covers all adapters.
Safety
Flue acts inside professional desktop software. Treat the human as the driver; prefer small, inspectable steps; avoid destructive actions unless explicitly requested. Flue is MIT-licensed and reviewable on GitHub / PyPI before use.
What ships with it
1 file 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.

Houdini is a skill published in the GitHub repository SFKislev/Flue (79 stars, last pushed 6d ago), licensed MIT. It adds 26 tokens to every session and 392 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 84% identical to Audition, differing in 16 lines, and is treated as a copy.
