BF synthclaw

Render Blender files with agent-controlled procedural parameters for synthetic data generation. A key capability of this skill is returning dynamic quality metrics (Naturalness and LPIPS) upon generation and measuring dataset-wide diversity (Shannon entropy), allowing agents to be guided by the metric results to iteratively optimize parameter ranges and improve synthetic data usefulness. Supports CYCLES (production) and EEVEE (fast testing) render engines.

How to improve

  1. The text references files that are not there: add them or drop the references.
For the model run — optional
  • Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
  • A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.

Quality signals

  • +5Description has no quoted example phrases that should trigger the skill
  • +4Description does not say when NOT to use the skill (false activations)
  • +3Output format is not stated: the model decides each time
  • -4Absolute local paths (C:\Users, /home/…): not portable
  • -31 of 4 scripts are never mentioned in SKILL.md
  • +2Single-language instructions

External checks

ClawHub: suspicious
This Blender rendering skill mostly matches its purpose, but it needs Review because it runs user-supplied Blender files with the normal environment and can delete TIFF files inside the chosen output folder.
