+
+# Run 16
+
+Replace the `==` marked instructions in this file while you work on the task.
+
+## Context
+
+Read the `AGENTS.md` and `README.md` to get understanding of the project.
+
+## Task
+
+Please update the  `addons/project/project_phase_estimate` module.
+
+Here is the first task. 
+When I open the task form and click on `phase_id` the `project_id` is passed as context. Then on the `project.task.phase` form I click on `action_project_estimate` and create a new estimate. The new estimate should be prefilled with the `project_id`. Can you make sure the `project_id`is  passed as context from the task from to the estimate tree?
+
+Then I have another task.
+When I click on "Project > Project Phases > Project Estimates", I want to see all estimates grouped by project by default.
+
+And another task.
+When I add a project phase to a task, ensure that the linked project has an estimate for this phase. If there is not estimate, create one and set planned time to 0.
+
+Then I have final request.
+Make sure that the combination of phase and project for an estimate is unique.
