Issues Summary

No HIGH or MEDIUM issues found.

🟢 Low Priority Notes (1 item)

• Consider removing getAiHeaders and GetAiHeadersParams entirely - src/ipc/utils/provider_options.ts — The function now unconditionally returns undefined and the parameter is prefixed with _ (unused). YAGNI suggests removing it. However, since it's already wired into 3 call sites, keeping the no-op stub avoids re-threading when a new beta header is needed — a reasonable trade-off.

None.

Code Review

This pull request refactors the getAiHeaders function in src/ipc/utils/provider_options.ts to remove the Anthropic-specific beta header logic, effectively turning it into a placeholder that returns undefined. I have no feedback to provide.
