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.

Process rating: all ten parameters 37/100

Will not run. References files that are not bundled: techniques/ray-marching.md, techniques/sdf-3d.md, techniques/csg-boolean-operations.md
  • 0Tools and files. 37 referenced file(s) missing: techniques/ray-marching.md, techniques/sdf-3d.md, techniques/csg-boolean-operations.md
  • 0Result and completion. Does not say what the result is
  • 0Inputs and preconditions. Does not say what the process needs to start
  • 30Running it twice. 3 mutating operations with no state check
  • 40Consistency. Frontmatter name (shader-dev) differs from the folder (minimax-shader-dev)
  • 50When it triggers. No condition that starts the skill
  • 55Failures and branches. 1 branches
  • 70Execution cost. Instruction body is 4091 tokens
  • 100Steps. 81 steps
  • 100Progress reporting. Reports progress
  • low 10 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.

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
  • +2Single-language instructions
  • +3Description length 199: enough signal without eating the budget
  • +4Structure: 33 headings
  • +3Step-by-step instructions: 81 items
  • +4Has examples (8 code blocks)
  • +1License stated

Quality base 70; lint remarks subtract, signals add up to 100. Result: 61.
