name: Claude Code Review # Dual triggers: # - pull_request: used for same-repo PRs so the Claude App's OIDC -> # installation-token exchange succeeds (it rejects OIDC tokens minted # under pull_request_target with "Invalid OIDC token"). This path posts # a real GitHub Review with inline comments authored by claude[bot]. # - pull_request_target: used for fork PRs, where secrets are not # available on the pull_request trigger. This path uses GITHUB_TOKEN # to bypass the OIDC exchange; findings are issue comments authored by # github-actions[bot]. # Each job gates on github.event_name AND head.repo so exactly one automatic # review runs when a PR is opened.
