This benchmark measured an earlier version of the skill.
A newer attempt on gemini-3.6-flash on 10/2/2026 did not produce a publishable comparison (not comparable). The snapshot above is the previously measured run.
One of 8 test cases the skill fixed. Same model, same prompt, with and without the skill.
I am running the skill review tool on a headless Linux server without a display or browser launcher. What flag should I pass to `generate_review.py` to produce a standalone review file?
| Checked | Without skill | With skill |
|---|---|---|
| Passes the --static flag with an output file path. | Missed | Passed |
The instructions your model reads when the skill loads.
A skill for creating new skills and iteratively improving them.
At a high level, the process of creating a skill goes like this:
eval-viewer/generate_review.py script to show the user the results for them to look at, and also let them look at the quantitative metricsYour job when using this skill is to figure out where the user is in this process and then jump in and help them progress through these stages. So for instance, maybe they're like "I want to make a skill for X". You can help narrow down what they mean, write a draft, write the test cases, figure out how they want to evaluate, run all the prompts, and repeat.
On the other hand, maybe they already have a draft of the skill. In this case you can go straight to the eval/iterate part of the loop.
Of course, you should always be flexible and if the user is like "I don't need to run a bunch of evaluations, just vibe with me", you can do that instead.
Then after the skill is done (but again, the order is flexible), you can also run the skill description improver, which we have a whole separate script for, to optimize the triggering of the skill.
Cool? Cool.
The skill creator is used by people across a wide range of familiarity with coding jargon, from people opening a terminal for the first time to experienced developers; most are fairly computer-literate.
So please pay attention to context cues to understand how to phrase your communication! In the default case, just to give you some idea:
It's OK to briefly explain terms if you're in doubt, and feel free to clarify terms with a short definition if you're unsure if the user will get it.
