+## Organization instruction routing
+
+Organization policy is owned by [`z-shell/.github` `AGENTS.md`](https://github.com/z-shell/.github/blob/main/AGENTS.md). Read it before non-trivial work. Repository guidance in this file and in the surfaces below narrows implementation detail and never overrides organization policy.
+
+Before acting, select every surface below whose tasks and file patterns both match the work, and read each one. If your runtime does not load a listed file automatically, open it explicitly.
+
+- `AGENTS.md` (this file): tasks `all`; files `**`
+- `.github/skills/code-review/SKILL.md`: tasks `code-review`, `review-readiness`, `organization-review`, `project-health`, `repository-health`, `repository-health-audit`, `repository-health-check`; files `**`; organization skill vendored at approved revision `e1f8f6c1c9dd`
+
+Organization-wide surfaces are routed by the [organization manifest](https://github.com/z-shell/.github/blob/main/.github/instruction-surfaces.json). This block is delivered and verified under [decision 0031](https://github.com/z-shell/.github/blob/main/decisions/0031-per-repository-instruction-routing-delivery.md).

+<!-- END org-routing -->

 This project follows the organization-wide [Z-Shell Organization Guidelines](https://github.com/z-shell/.github/blob/main/AGENTS.md).
