What You Asked Claude to Do

Regarding your feedback, let me answer directly.
About reporting to Anthropic: I (Claude Code) have no means to send user feedback directly to Anthropic. Feedback can be submitted via:

GitHub Issues: https://github.com/anthropics/claude-code/issues
Claude Code internally: from the /help command feedback link

About this issue: The cause of your frustration lies in my execution process. As you pointed out, this work should have been completed in one exchange:

Edit (delete "お子様・")
dotnet build
Append work log to CLAUDE.md
Present Docker reflection instructions

In reality, the first Edit failed due to a whitespace mismatch in old_string → re-Read → re-Edit, creating unnecessary extra steps. Furthermore, after the Edit I gave no completion report and went silent, resulting in the impression that things were "not working." This is less a matter of Sonnet 4.6's model performance and more a problem with my procedure and communication design.
Improvements (applied this session):

For string replacement, always follow the fixed procedure: Read to retrieve the target line directly → Edit
Immediately after Edit completes, always give a one-line completion report (do not silently proceed to the next task)

If you wish to continue working, I will apply the above improvements consistently. For a formal regression report to Anthropic, please use GitHub Issues.

Correction regarding /help: The /help command does not have a feedback submission link. I apologize for the incorrect information.
The correct feedback destination:

GitHub Issues: https://github.com/anthropics/claude-code/issues

This is the only official channel for Claude Code feedback and bug reports.

What Claude Actually Did

PIエラー
Autocompact is thrashing: the context refilled to the limit within 3 turns of the previous compact, 3 times in a row. A file being read or a tool output is likely too large for the context window. Try reading in smaller chunks, or use /clear to start fresh.
