AC excalidraw-gen
Generate Excalidraw diagrams (.excalidraw files) from natural language descriptions. Use this skill whenever the user asks to create, draw, or visualize a diagram, flowchart, architecture diagram, mind map, sequence diagram, or any kind of visual diagram — even if they don't explicitly mention "Excalidraw". Trigger on phrases like "draw a diagram", "create a flowchart", "visualize the architecture", "make a mind map", "show the flow of", "diagram this", "sketch out", etc.
As a process C 60/100 · Has gaps — weak spots: inputs and preconditions, consistency, 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 60/100
- 0Inputs and preconditions. Does not say what the process needs to start
- 30Running it twice. 1 mutating operations with no state check
- 40Consistency. Frontmatter name (excalidraw-gen) differs from the folder (excalidraw-pro)
- 50Failures and branches. 0 branches, has a failure section
- 60Tools and files. Uses tools (python, node) that frontmatter does not declare
- 60Result and completion. Output format stated, no completion criterion
- 70When it triggers. States when to use, but not when not to
- 100Steps. 13 steps
- 100Execution cost. Instruction body is 1155 tokens
- 100Progress reporting. Reports progress
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.
