AA aspect-calc
Calculate aspect ratios from dimensions and find missing width or height. Use when the user asks to calculate an aspect ratio, find the height for a given width, simplify a ratio, or resize dimensions while preserving aspect ratio.
As a process A 86/100 · Runs to the end — weak spots: progress reporting
How to improve
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.

- 0Progress reporting. Says nothing while it works
- 60Result and completion. Output format stated, no completion criterion
- 70When it triggers. States when to use, but not when not to
- 70Inputs and preconditions. Inputs and preconditions are listed
- 100Tools and files. No external tools needed
- 100Steps. 43 steps
- 100Failures and branches. 2 branches, has a failure section

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.
