How to improve

  1. The SKILL.md body is over 5,000 tokens: move reference detail into references/ and load it when needed.
  2. The text references files that are not there: add them or drop the references.
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.

Against the Agent Skills spec

  • warning body-long SKILL.md body ≈ 5282 tokens (recommended < 5000); move details to references/
  • warning missing-ref reference to a missing file: examples/*.puml
  • warning missing-ref reference to a missing file: assets/preview/

Process rating: all ten parameters 26/100

Will not run. References files that are not bundled: examples/*.puml, assets/preview/
  • 0Tools and files. 2 referenced file(s) missing: examples/*.puml, assets/preview/
  • 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
  • 20When it triggers. No condition that starts the skill
  • 30Running it twice. 3 mutating operations with no state check
  • 40Consistency. Frontmatter name (plantuml) differs from the folder (plantuml-diagrams)
  • 70Execution cost. Instruction body is 5282 tokens
  • 100Steps. 135 steps
  • low 26 top-level sections: this looks like several domains in one skill
  • low The response is described with custom markup (16 tags): a typed call is more reliable

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 294: enough signal without eating the budget
  • +4Structure: 93 headings
  • +3Step-by-step instructions: 135 items
  • +4Has examples (48 code blocks)
  • +4Reference files are cited in the instructions (1 of 2)
  • +3All 1 scripts are documented

Quality base 70; lint remarks subtract, signals add up to 100. Result: 72.

This PlantUML skill is coherent and purpose-aligned, with a privacy caveat because remote rendering can send diagram text to PlantUML’s public server.
