How to improve

  1. Say in the description WHEN to use the skill ("use when…", example requests): that is the agent's main cue.
  2. For Hermes the description must be one sentence under 60 characters; move the conditions to a "When to Use" section.
  3. 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 name-format name should be kebab-case (lowercase letters, digits, hyphens)
  • warning description-long-hermes description is 150 chars; the Hermes authoring standard requires ≤ 60 (one sentence, ending with a period)
  • warning description-no-when neither description nor a "## When to Use" section says when to use the skill
  • warning missing-ref reference to a missing file: data.images[0].image.viewUrl
  • warning missing-ref reference to a missing file: data.images[0].image.downloadUrl
  • warning missing-ref reference to a missing file: data.images[1].image.viewUrl
  • warning missing-ref reference to a missing file: data.images[1].image.downloadUrl

Process rating: all ten parameters 46/100

Will not run. References files that are not bundled: data.images[0].image.viewUrl, data.images[0].image.downloadUrl, data.images[1].image.viewUrl
  • 0Tools and files. 8 referenced file(s) missing: data.images[0].image.viewUrl, data.images[0].image.downloadUrl, data.images[1].image.viewUrl
  • 0Inputs and preconditions. Does not say what the process needs to start
  • 20When it triggers. No condition that starts the skill
  • 30Running it twice. 3 mutating operations with no state check
  • 40Consistency. Frontmatter name (NK Images Search) differs from the folder (nk-images-search)
  • 60Result and completion. Output format stated, no completion criterion
  • 85Steps. 82 steps, 1 vague phrases
  • 100Failures and branches. 2 branches, has a failure section
  • 100Execution cost. Instruction body is 3790 tokens
  • 100Progress reporting. Reports progress
  • medium Safety rules and hard prohibitions inside a skill: they belong in the system prompt, here they protect nothing
  • low 12 top-level sections: this looks like several domains in one skill

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.
