 # Changelog
 
+## [0.11.15.0] - 2026-03-24 — E2E Test Coverage for Plan Reviews & Codex
+
+### Added
+
+- **E2E tests verify plan review reports appear at the bottom of plans.** The `/plan-eng-review` review report is now tested end-to-end — if it stops writing `## GSTACK REVIEW REPORT` to the plan file, the test catches it.
+- **E2E tests verify Codex is offered in every plan skill.** Four new lightweight tests confirm that `/office-hours`, `/plan-ceo-review`, `/plan-design-review`, and `/plan-eng-review` all check for Codex availability, prompt the user, and handle the fallback when Codex is unavailable.
+
+### For contributors
+
+- New E2E tests in `test/skill-e2e-plan.test.ts`: `plan-review-report`, `codex-offered-eng-review`, `codex-offered-ceo-review`, `codex-offered-office-hours`, `codex-offered-design-review`
+- Updated touchfile mappings and selection count assertions
+- Added `touchfiles` to the documented global touchfile list in CLAUDE.md
+
