Review comment posted on PR #19227. Here's the summary:

The Kotlin code is valid and idiomatic. The core patterns — S3Client.fromEnvironment, .use {} for resource cleanup, StaticCredentialsProvider, and the presigner API — are all correct.

Two items worth addressing:

1. Unused imports in Basic Usage block — Lines 19–22 and 26 import presigner-related classes that are only used in the second code block. This would produce compiler warnings if someone copies just the first example. The presigned URLs snippet also references r2Client and bucketName which are scoped inside the .use {} lambda, so some restructuring or a clarifying note would help.

2. listObjects vs listObjectsV2 — The example uses the older v1 API. listObjectsV2 is the recommended modern API and is what other SDK examples in these docs tend to use.

/bonk fix the examples so they are self-contained and use listObjectsV2

[ask-bonk]

The file looks correct. Here's a summary of the changes made:

Basic Usage block (lines 15-50):

• Removed unused presigner imports (GetObjectRequest, PutObjectRequest, presignGetObject, presignPutObject, Duration.Companion.minutes) that would cause compiler warnings if someone copies just this example
• Replaced listObjects (v1 API) with listObjectsV2 (recommended modern API), using ListObjectsV2Request — consistent with other SDK examples in the docs (Java, Rust, Go, JS v3, PHP all use listObjectsV2)

Presigned URLs block (lines 66-114):

• Made fully self-contained with its own imports, credential placeholders, main() function, and S3Client setup inside a .use {} block
• Previously referenced r2Client and bucketName that were scoped inside the Basic Usage .use {} lambda and wouldn't be accessible — copying that snippet alone would not compile
