AB pptxgenjs-compat
This skill should be used when generating PPT files with pptxgenjs (Node.js library). It provides a complete workflow for creating PowerPoint-compatible PPTX files that won't trigger the "PowerPoint found a problem with content" repair dialog. Covers: safe API usage patterns, post-processing fixes for known pptxgenjs defects, and compatibility verification. Trigger when: creating PPT with pptxgenjs, fixing pptxgenjs-generated PPTX files, or whenever "pptxgenjs" or "PPT" generation is mentioned.
As a process B 70/100 · Nearly there — weak spots: result and completion, inputs and preconditions, running it twice
How to improve
- 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.

Process rating: all ten parameters 70/100
- 0Result and completion. Does not say what the result is
- 0Inputs and preconditions. Does not say what the process needs to start
- 0Progress reporting. Says nothing while it works
- 30Running it twice. 3 mutating operations with no state check
- 100Tools and files. No external tools needed
- 100Steps. 15 steps
- 100When it triggers. States when to use and when not to
- 100Failures and branches. 2 branches, has a failure section
- 100Consistency. Name and required fields are in place
- 100Execution cost. Instruction body is 961 tokens
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.
