BF cad-viewer
This skill should be used when the user wants to read, analyze, or work with CAD DWG/DXF drawing files. Trigger phrases include: DWG, DXF, CAD drawing, drawing analysis, layer, block, entity, screenshot, distance calculation, drawing audit, electrical diagram, distribution box, single-line diagram, or any mention of .dwg/.dxf files. This skill provides comprehensive CAD drawing analysis capabilities including reading file metadata, listing layers and entities, analyzing block definitions, calculating distances between entities, capturing screenshots of specific regions or entities, and auditing drawing compliance.
This skill should be used when the user wants to read, analyze, or work with CAD DWG/DXF drawing files.
As a process F 60/100 · Will not run — References files that are not bundled: assets/.setup_done
How to improve
- The SKILL.md body is over 5,000 tokens: move reference detail into references/ and load it when needed.
- The text references files that are not there: add them or drop the references.
- 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.

- low 12 top-level sections: this looks like several domains in one skill
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.
