Amazing, thanks for working on this.


But I could not get it to work with gemini:
I have:

    [b4]
      review-agent-command = gemini --sandbox --allowed-tools 'Bash(git:*) Read Glob Grep Write(.git/b4-review/**) Edit(.git/b4-review/**)'
      review-agent-prompt-path = .git/agent-reviewer.md


and this runs:

gemini --sandbox --allowed-tools Bash(git:*) Read Glob Grep Write(.git/b4-review/**) Edit(.git/b4-review/**) -- Read the prompt from /scm/b4/.git/agent-reviewer.md


But this just gets me an interactive prompt:
