# PR Review Bot
# Triggers on PR open/sync, runs Claude Code review with rich context,
# posts structured review comment to Codeberg.
#
# NOTE: This runs on the host (not in Docker) because it needs:
#   - claude CLI
#   - git worktrees in the harb repo
#   - ~/.netrc for Codeberg API
#
# For now, trigger manually or via webhook → script.
# TODO: Move to Woodpecker "local" backend when ready.

when:
  event: pull_request
  # Only review PRs targeting master
  branch: master

steps:
  review:
    image: alpine
    commands:
      # This is a placeholder — actual review runs on host via script.
      # Woodpecker's Docker backend can't access claude CLI.
      #
      # Two options for triggering:
      #
      # Option A: Codeberg webhook → OpenClaw cron/system event → review script
      #   - Codeberg sends PR webhook to OpenClaw gateway
      #   - Gateway triggers: scripts/review-pr.sh $PR_NUMBER
      #
      # Option B: Woodpecker local backend
      #   - Run woodpecker-agent with local backend (no Docker)
      #   - Pipeline runs directly on host
      #   - scripts/review-pr.sh ${CI_PULL_REQUEST_NUMBER}
      #
      - echo "PR review should be triggered via host script"
      - echo "Run: scripts/review-pr.sh ${CI_PULL_REQUEST_NUMBER:-unknown}"
