AB yummy-gen-image
Use when the user wants to generate or edit raster images with Gemini through yummycli, including prompt-only generation, single-image editing, and multi-image reference editing.

How to improve
- For Hermes the description must be one sentence under 60 characters; move the conditions to a "When to Use" section.
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.

Process rating: all ten parameters 72/100
- 0Result and completion. Does not say what the result is
- 0Progress reporting. Says nothing while it works
- 30Running it twice. 2 mutating operations with no state check
- 60Consistency. The Hermes dialect needs category and tags
- 70Inputs and preconditions. Inputs and preconditions are listed
- 70Failures and branches. 7 branches
- 100Tools and files. No external tools needed
- 100Steps. 21 steps
- 100When it triggers. States when to use and when not to
- 100Execution cost. Instruction body is 1297 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.
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
- +1No license
- +2Single-language instructions
- +3Description length 178: enough signal without eating the budget
- +4Structure: 10 headings

- +4Has examples (8 code blocks)
Quality base 70; lint remarks subtract, signals add up to 100. Result: 77.

The skill's requirements and instructions are coherent with an image-generation wrapper around the yummycli/Gemini API, but review the npm package provenance and the referenced yummy-shared skill before installing.
