Developer's Git commit hook with Claude Code hangs indefinitely on LLM call

By PulseAugur Editorial · [1 sources] ·

A developer integrated Anthropic's Claude Code into their Git commit process, using a hook to automatically generate commit messages from staged diffs. The setup, however, lacked a timeout for the LLM call, causing `git commit` to hang indefinitely if the Claude CLI process stalled due to network issues or server startup problems. This resulted in a frozen terminal with no error indication, and in some failure scenarios, the hook would silently overwrite the default commit message template with an empty file, though Git's own safeguards prevented empty commits from being saved.
