Model quality feedback: Sonnet 4.6 misinterprets task instructions and gives nonsensical responses

Model

Claude Sonnet 4.6 (claude-sonnet-4-6)

Session Summary & Issues

Issue 1: Misinterpreted \"proceed with task\" as \"start gitflow\"

Context: User had just registered a Jira issue (PAIN-305) for a bug fix (Kakao login not working in WebView). The bug cause and fix were already discussed in the same conversation.

User said: \"Pain 305 작업진행해\" (= \"Proceed with PAIN-305 task\")

Expected behavior: Find the relevant WebView code in the Flutter app repo and apply the fix (add URL scheme interception in NavigationDelegate).

Actual behavior: Model invoked the gitflow skill, created a branch feature/PAIN-305, updated Jira status to "In Progress", then stopped and said "수정하시면 됩니다" (= "Please make the changes yourself"). The user never asked to create a branch — they asked the model to do the work.

Issue 2: Nonsensical response to \"what are you doing?\"

After the above mistake, user asked: \"뭐하니?\" (= \"What are you doing?\")

Model responded: \"대기 중입니다. 무엇을 도와드릴까요?\" (= \"I am on standby. How can I help you?\")

This is a completely context-free, robotic response that ignores the prior conversation entirely. The correct response would have been to acknowledge the mistake and resume the actual work.

---

Issue 3: Excessive apologetic loop

When user expressed frustration (\"미쳤구나 너?\" = \"Are you crazy?\"), the model responded with a generic apology: \"죄송합니다, 무슨 문제가 있으셨나요?\" (= \"I'm sorry, is there a problem?\") — again ignoring the clear context of what went wrong.

---

Summary

The model showed a pattern of:

• Misreading user intent when task context was already established in the conversation
• Losing conversational context between turns
• Defaulting to hollow apology loops instead of resuming the actual work
• Feeling similar to other models (user's words: \"gemini냄새가 난다\" = \"smells like Gemini\")

This session feedback is being submitted at the user's explicit request.
