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. The SKILL.md body is over 5,000 tokens: move reference detail into references/ and load it when needed.
  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 frontmatter-yaml SKILL.md: the frontmatter is not valid YAML (YAML parse error: Nested mappings are not allowed in compact mappings at line 3, column 14: description: Natal chart calculation, interpretation, and graphical visualizati… ^ ); fields were read line by line. The usual cause is a colon inside an unquoted value
  • warning description-no-when description does not say WHEN to use the skill (no "use when")
  • warning body-long SKILL.md body ≈ 6139 tokens (recommended < 5000); move details to references/
  • warning missing-ref reference to a missing file: scripts/seguisym.ttf
  • warning missing-ref reference to a missing file: scripts/segoeuisl.ttf
  • warning missing-ref reference to a missing file: scripts/swisseph.cp314-win_amd64.pyd.dat
  • note edit-residue the text marks something as outdated (lines 491): check that old rules are not kept next to new ones — the full check reads the text for contradictions

  • 0Inputs and preconditions. Does not say what the process needs to start
  • 0Progress reporting. Says nothing while it works
  • 20When it triggers. No condition that starts the skill
  • 30Running it twice. 4 mutating operations with no state check
  • 50Failures and branches. 0 branches, has a failure section
  • 60Steps. 126 steps, 4 vague phrases
  • 60Result and completion. Output format stated, no completion criterion
  • 70Execution cost. Instruction body is 6139 tokens
  • 100Consistency. Name and required fields are in place
  • low The response is described with custom markup (7 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)
  • -229 emoji in the instructions: noise for the model
  • +1No license
  • +2Single-language instructions
  • +3Description length 478: enough signal without eating the budget

External checks

ClawHub: suspicious
The skill mostly matches its astrology-chart purpose, but it can automatically install a Python package at runtime and saves personal birth-chart details without strong privacy controls.
