Thin entry-point skill — routes to the parent skill for full workflow.
Parent Skill
This skill delegates to test-review for the underlying transport. As a thin entry point it dispatches nothing itself, so it holds no transport grant. The generation-specific prompt template is at @skills/test-review/references/codex-prompt-test-gen.md.
See @skills/test-review/SKILL.md
