Internal cross-links to other dev-guides topics (TDD & Spec-Driven Development, ATK, Playwright E2E, Visual Regression) also appear in the guide body. They are related-guide references, not research sources, and are not listed here.

1.57.0 (npm) — guide states "1.56+"; the agent files, tool names (planner_save_plan), and Planner/Generator/Healer split match this installed copy |

The Drupal-specific example code in Section 16 (site_contact module, *.routing.yml) is example code in the guide, not verified against an installed module — no site_contact module exists under contrib/web, so this pass could not confirm those specifics against a real Drupal installation. The ATK seed script and selector hooks were checked against ATK 2.1.0-beta5 source; site_contact remains unverified. @playwright/mcp (the MCP server package used in Section 14) is not installed locally in this workspace; its registry version (0.0.80 at verification time) is not asserted in the guide text and is not verified in this pass.

Section 16 seed test: its own seed project, excluded from chromium, named in the agent prompt. Checked against playwright 1.63.0 lib/mcp/test/seed.js and testContext.js, and the 1.63 test-agents docs. Snapshot name aligned to qa. |
