Problem

Currently the CI workflow runs Sonnet and GPT reviews sequentially in the same job. Total review time is additive (30-60s per model = 60-120s total).

Proposed Solution

Two approaches (not mutually exclusive):

1. Parallel CI jobs

Split into separate jobs that run concurrently:

jobs:
  review-sonnet:
    runs-on: ubuntu-24.04
    ...
  review-gpt:
    runs-on: ubuntu-24.04
    ...

Both depend on test passing but run independently of each other.

2. Built-in parallel mode

Add a --parallel flag or multi-reviewer config so a single invocation dispatches both reviews concurrently using goroutines:

review-bot --config reviewers.yaml

Where reviewers.yaml defines multiple reviewer profiles (model, token, name).

Benefits

  • Cuts wall-clock time in half
  • Reviews post roughly simultaneously
  • Better resource utilization

Considerations

  • Approach 1 is simpler but requires building the binary twice (or downloading from release)
  • Approach 2 is more elegant but needs careful error handling (one reviewer failing should not block the other)
  • Both approaches need separate Gitea tokens per reviewer to avoid auth conflicts
