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 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 description-no-when description does not say WHEN to use the skill (no "use when")
  • warning missing-ref reference to a missing file: references/token-formula.md
  • warning missing-ref reference to a missing file: memory/topic-name.md
  • warning missing-ref reference to a missing file: references/memory-extraction-pattern.md

Process rating: all ten parameters 35/100

Will not run. References files that are not bundled: references/token-formula.md, memory/topic-name.md, references/memory-extraction-pattern.md
  • 0Tools and files. 3 referenced file(s) missing: references/token-formula.md, memory/topic-name.md, references/memory-extraction-pattern.md
  • 0Result and completion. Does not say what the result is
  • 0Inputs and preconditions. Does not say what the process needs to start
  • 20When it triggers. No condition that starts the skill
  • 30Running it twice. 6 mutating operations with no state check
  • 40Consistency. Frontmatter name (token-optimizer) differs from the folder (claude-code-api-optimizer-skill)
  • 55Failures and branches. 1 branches
  • 100Steps. 45 steps
  • 100Execution cost. Instruction body is 1778 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.

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)
  • +3Description length 115: 120–800 characters recommended
  • +3Output format is not stated: the model decides each time
  • +1No license
  • +2Single-language instructions
  • +4Structure: 14 headings
  • +3Step-by-step instructions: 45 items
  • +4Has examples (4 code blocks)

Quality base 70; lint remarks subtract, signals add up to 100. Result: 57.

External checks

ClawHub: clean
This instruction-only token optimizer is coherent and low-risk, but users should understand that it may save selected conversation facts into local memory files.
