GitHub App auth was exempting public repos from automatic min-integrity: approved protection. Repo scoping (what App auth provides) and author-integrity filtering (what min-integrity provides) are orthogonal — a repo-scoped App token still exposes workflows to untrusted same-repo content unless a guard policy filters it.

Changes

  • compiler_github_mcp_steps.go: Remove the hasGitHubApp() early-return that skipped generating the determine-automatic-lockdown step for App-authenticated workflows
  • mcp_environment.go: Remove && !appConfigured so GITHUB_MCP_GUARD_MIN_INTEGRITY / GITHUB_MCP_GUARD_REPOS env vars are wired consistently regardless of token type
  • github_mcp_app_token_test.go: Rename TestGitHubMCPAppTokenNoLockdownDetectionStepTestGitHubMCPAppTokenWithLockdownDetectionStep; flip assertions to verify the determine-automatic-lockdown step is generated when a GitHub App is configured
  • lockdown-mode.md: Remove the bullet stating automatic guard policy does not apply when tools.github.app is configured
  • determine_automatic_lockdown.cjs: Drop stale comment advertising the App exemption

Pull request overview

Removes the GitHub App authentication exemption so public repositories still receive automatic min-integrity: approved guard policy protection when tools.github.app is configured.

Changes:

  • Always generate the determine-automatic-lockdown step when GitHub guard policy isn’t explicitly configured (even with GitHub App auth).
  • Wire GITHUB_MCP_GUARD_MIN_INTEGRITY / GITHUB_MCP_GUARD_REPOS env vars consistently regardless of token type, and update tests/docs accordingly.
  • Updates a checked-in lock workflow file (smoke-codex.lock.yml) with regenerated output.

  • The generated safe-outputs action tool schema for add_smoked_label has degraded to a generic payload string with additionalProperties: true. This likely indicates the compiler couldn't resolve the action's action.yml inputs, but committing this will remove input validation and no longer exposes the expected labels parameter to the agent. Regenerate this lock file with action inputs successfully resolved (so the schema includes the action’s real inputs, e.g., labels), or otherwise ensure action input metadata is available at compile time (cache/vendor it) so the schema remains deterministic.

This issue also appears on line 1560 of the same file.

  • This safe-outputs injected step now passes a single payload input to actions-ecosystem/action-add-labels@v1. That action expects concrete inputs like labels (and optionally number), so this step will be a no-op or fail due to missing required inputs. The lock file should pass the resolved action inputs (e.g., labels: ${{ fromJSON(...).labels }}), which requires the compiler to successfully parse the action’s action.yml during compilation.

          GITHUB_TOKEN: ${{ github.token }}
        with:
