What's Wrong?

A Claude workflow with Claude Github agent fails with SDK execution error: 14. since Feb 6.
Before that is ran successfully

This is an exceprt from the error log:
error: Claude Code process exited with code 1
at $ (/home/runner/work/_actions/anthropics/claude-code-action/v1/node_modules/@anthropic-ai/claude-agent-sdk/sdk.mjs:19:7919)
at emit (node:events:98:22)
at #handleOnExit (node:child_process:520:14)

Error: Action failed with error: SDK execution error: Error: Claude Code process exited with code 1

claude.yml

What Should Happen?

PR should be reviewed by Claude succesfully. It did so a couple of times, but since no changes from my side it started to fail from Feb 6 and on.
