AB ppt-from-template
Generate presentations by extracting visual style from a reference template and recreating slides from scratch using PptxGenJS. Use when: user provides a PPT/PDF as style reference and wants new slides in that style; user says "按这个风格做PPT", "模仿这个模板", "参考这个PDF做演示", "make slides like this", "use this template", "做个PPT", "用这个模板做课件", "帮我做演示文稿"; user uploads a .pptx file as template. Supports: template directory auto-discovery, user upload, multi-template selection, image/video placeholders, large decks (30-100+ pages via batched generation). Requires: pptx skill (PptxGenJS), python-pptx, pdftoppm (poppler-utils). NOT for: editing existing PPT (use pptx skill), creating slides without style reference (use pptx skill directly).
As a process B 68/100 · Nearly there — weak spots: inputs and preconditions, running it twice, progress reporting
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 68/100
- 0Inputs and preconditions. Does not say what the process needs to start
- 0Progress reporting. Says nothing while it works
- 30Running it twice. 2 mutating operations with no state check
- 50When it triggers. No condition that starts the skill
- 50Failures and branches. 0 branches, has a failure section
- 60Result and completion. Output format stated, no completion criterion
- 100Tools and files. No external tools needed
- 100Steps. 21 steps
- 100Consistency. Name and required fields are in place
- 100Execution cost. Instruction body is 1322 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.
