Both model sets use Haiku 5.5 as judge.

Driftproof measured

Three text-only tasks: Clearly helped.

At least one task improved, with no task showing a clear drop.

Read test record

Why this result?

The skill clearly helped: 0.955 with it and 0.644 without, on 3 test tasks.

loop, timeline, render: higher scores with the skill. Compare task scores

Task score bands: loop (separated-up): with skill 0.906 plus or minus 0.068411; without skill 0.6875 plus or minus 0.047871; timeline (separated-up): with skill 0.983333 plus or minus 0.028868; without skill 0.5875 plus or minus 0.094648; render (separated-up): with skill 0.975 plus or minus 0.05; without skill 0.658333 plus or minus 0.073598.

A band is the average score plus or minus the recorded spread. These task bands, not the overall averages, determine the result.

0.955 with the skill and 0.644 without; on at least one of the 3 test tasks, the two ranges of scores (the average plus or minus one spread) did not overlap, and the gap was at least 0.05.

Test details and sources
How this result was decided

The reader applies the task rule, with a separated-down task taking precedence. Overall means do not determine the verdict. Bands show the mean plus or minus the recorded spread; point bands can reflect score quantization.

  • loop: separated-up. With skill 0.906 plus or minus 0.068411; without skill 0.6875 plus or minus 0.047871.
  • timeline: separated-up. With skill 0.983333 plus or minus 0.028868; without skill 0.5875 plus or minus 0.094648.
  • render: separated-up. With skill 0.975 plus or minus 0.05; without skill 0.658333 plus or minus 0.073598.

Three text-only tasks. Driftproof wrote the suite from the pinned skill description and README. These are not author-supplied tests. External tools, generated media and deployed services were not tested.

The eval account's configuration was read and found clean before and after each run, not during it.

How we test a skill

A skill gives an AI extra instructions. We ask: do those instructions improve its written answers?

  1. The task Same question. Same AI.

    Driftproof writes tasks from the skill description.

    Give the AI a task
  2. The comparison Change the instructions
    With the skill Written answer
    Without the skill Written answer

    Repeat both ways to see how much answers vary.

  3. The result Judge each task
    Haiku 5.5 scores the answers

    A clear drop on any task takes priority. Otherwise, a better task can mean the skill helped. When answers vary too much, we cannot settle the result.

These tests cover written answers, not installation, tool use or how useful a skill is in general.
