Tokens, turns and time describe resource use, not a dollar price.
A test case the skill fixed. Same model, same prompt, with and without the skill.
Generate a synthetic Python benchmark script using the `timeit` module to measure performance execution differences between list comprehensions and `map()` across 1,000,000 iterations.

The instructions your model reads when the skill loads.
Make unfamiliar code understandable — fast — without dumbing it down.
Infer the language and intent from the code itself; label assumptions (assumed — confirm). Always produce a complete explanation even from a fragment. Match depth to the apparent level of the question.
The code snippet or file, plus (if given) the language, the reader's level, and what they're trying to understand. Infer the rest.
What this code does, in a single sentence a busy reader can repeat.
A walkthrough of the logic in order — group by block/function. Explain why, not just what, for anything non-trivial. Reference line ranges where helpful.
The non-obvious bits: clever tricks, gotchas, side effects, complexity, dependencies, or assumptions the code makes.
Bugs, edge cases, or smells you noticed while reading — with the fix. (If it's clean, say so.)
