What's Wrong?

Description:

When I ask Claude Code to look at a GitHub issue by number (e.g., "Let's tackle GitHub issue 77"), it defaults to querying the anthropics/claude-code repository instead of my current project's repository.

Expected behavior:

Claude Code should default to the repository of the current working directory, matching how gh issue view <number> works when run without a --repo flag.

Actual behavior:

Claude Code first attempts to query anthropics/claude-code, likely because it associates itself with Anthropic. This requires me to correct it before it checks my actual project.

What Should Happen?

When a user references a GitHub issue without specifying a repository, always default to the current project's repo (detectable via git remote or the gh CLI's default behavior).

Additional Information

This seems to have started happening with latest Opus 4.5. When I was mostly using Sonnet 4.5 and Opus 4.1, I never had this problem.
