AC display-quantitative-information
Use this skill when the user needs to design, critique, redesign, audit, generate, code, or explain quantitative graphics: charts, dashboards, tables, maps, scientific/statistical figures, visual evidence, or chart specifications. It helps choose display forms, avoid misleading encodings, compute lie factors, inspect CSV structure, generate simple SVG charts, check color contrast, and produce Tufte-informed but non-formulaic recommendations. Do not use for decorative illustration or general data cleaning unless a quantitative display is involved.
As a process C 60/100 · Has gaps — weak spots: result and completion, inputs and preconditions, failures and branches
How to improve
- 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
- 0Result and completion. Does not say what the result is
- 0Inputs and preconditions. Does not say what the process needs to start
- 0Failures and branches. Linear process with no failure handling
- 0Progress reporting. Says nothing while it works
- 30Running it twice. 4 mutating operations with no state check
- 100Tools and files. No external tools needed
- 100Steps. 24 steps
- 100When it triggers. States when to use and when not to
- 100Consistency. Name and required fields are in place
- 100Execution cost. Instruction body is 1491 tokens
- medium 6 test cases, all positive: not one "should refuse" or "should ask first"
- low No test case covers injection arriving through data
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.
