 ## Implementation Workflow
 
-Every feature or phase implementation must follow this "Vertical Slice" approach:
+Every feature or phase implementation MUST start with a rigorous planning and design phase:
 
-1.  **Shared Layer**: Define types, enums, and Zod v4 schemas in `packages/shared`. Add unit tests.
+0.  **Mandatory Planning (Grilling)**: Before starting any feature or bug fix, you MUST invoke the `grill-with-docs` skill.
+    - Run the skill using: `view_file` on `.agents/skills/grill-with-docs/SKILL.md` and follow its instructions.
+    - This session will stress-test your plan against the existing domain model, terminology, and documentation (`CONTEXT.md`, ADRs).
+    - Decisions must be crystallized and documentation (glossary/ADRs) updated before moving to implementation.
+
+1.  **Vertical Slice Implementation**: Follow this approach for the actual build:
 2.  **Database Layer**: Create the Mongoose schema and Repository in `packages/api`. All reads must use `.lean().exec()`.
 3.  **Service Layer**: Implement business logic in the Service class, using Awilix for constructor injection. Add unit tests.
 4.  **Route Layer**: Create the Fastify route plugin and register it. Add route tests (using `app.inject`).
