Summary

When the backport cherry-pick to stable has merge conflicts, the workflow now attempts to resolve them automatically using opencode before falling back to manual instructions.

Flow

cherry-pick succeeds → push directly to stable (unchanged)
          ↓ (conflict)
   opencode resolves conflicts
          ↓ (success)
   create PR targeting stable for human review
          ↓ (failure)
   comment with manual resolution instructions (unchanged)

Changes

  • .github/workflows/backport.yml: Restructured to detect clean vs conflict outcomes. On conflict: installs the opencode CLI, configures Vercel AI Gateway credentials, runs opencode run with Claude Opus to resolve conflicts, then creates a PR for human review.
  • AGENTS.md: Updated backporting section to document the AI resolution step.

Setup required

Add the AI_GATEWAY_TOKEN repository secret with a Vercel AI Gateway API key.

Pull request overview

This PR enhances the backport-stable automation to distinguish clean cherry-picks from conflicted ones, and—when conflicts occur—attempt AI-assisted resolution via the opencode CLI before falling back to the existing manual-resolution guidance.

Changes:

  • Update the backport workflow to detect clean vs conflicted cherry-picks and push directly only on clean outcomes.
  • On conflicts, install/configure opencode and attempt AI-based conflict resolution; if successful, push a branch and open a PR to stable for human review.
  • Document the new AI-assisted backport behavior in AGENTS.md.
