houdini-hda-automation

houdini-hda-automation is a skill for Claude Code from dcc-mcp/dcc-mcp-houdini. It costs 85 tokens per session (861 once invoked), scanned A, original, MIT.

A Houdini automation toolset for Digital Assets (HDAs) and procedural batch networks. HDAs are reusable Houdini assets, while PDG/TOP networks coordinate many processing tasks.

In plain words
What is it for?
Use it to inspect HDA libraries and definitions, create and validate assets, cook PDG/TOP networks, and execute chains of Houdini output nodes.
Why use it?
It avoids manually scanning asset libraries, creating asset nodes, validating them, and launching connected batch jobs.

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-hda-automation 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 12d ago.

The scan reads SKILL.md. This mod also ships 7 executable files (scripts/_hda_auto_common.py, scripts/cook_top_network.py, scripts/execute_rop_chain.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.

houdini-hda-automation

Typed automation tools for Houdini Digital Assets (HDA/OTL) and procedural batch execution via PDG/TOP networks and ROP output-driver chains. Complements houdini-hda (which installs/lists/executes/saves HDAs) with library scanning, definition introspection, instantiation, validation, and graph-level cooking.

Tool groups

  • hda-query (read-only): scan_hda_libraries, inspect_hda_definition, validate_hda.
  • hda-edit: instantiate_hda (async — creates and cooks a node).
  • pdg-rop: async cook_top_network and self-managed execute_rop_chain.

Context limitations

  • Headless / no license: all tools degrade through structured skill_error envelopes when hou is unavailable; PDG/ROP cooking still requires a valid Houdini session.
  • Long runs: instantiate_hda, validate_hda, and cook_top_network use core async jobs. execute_rop_chain uses synchronous dispatch metadata so it returns its adapter-owned isolated job identity directly; poll it through houdini_render__get_render_job instead of occupying the Houdini event loop.
  • PDG stats: cook_top_network reports work_item_count on a best-effort basis via getPDGGraphContext(); it may be null when the context is unavailable.
  • ROP dependencies: execute_rop_chain honours upstream ROP inputs by default in both foreground and isolated workers; pass ignore_inputs=true to render only the named driver. UI and headless Houdini default to isolated hython; pass background=false only for intentional foreground execution. Interactive isolated launch requires a saved, clean HIP and never auto-saves the GUI scene. Headless isolation requires an existing HIP and captures its current state in a job-owned temporary snapshot without saving the source scene. A chain can complete without a discoverable output path when it has no execution/cook errors; inspect output_verification to distinguish this from verified file output.

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.
