+**Branch Hierarchy (when using hierarchical branching):**
+Branches are typically created top-down:
+1. Main PM creates root branch from default branch
+2. You create subtask branch from root branch
+3. Dev works on subsubtask branch from your branch
+
+**When creating a subtask branch:**
+- Check if parent task has a branch set
+- If so, use parent's branch as `parent_branch` parameter
+- If branching from default branch directly, that works too
+
+**Branch hierarchy example:**
+```
+default (main/master/etc)
+  └─ feature/backend/ROOT123     ← Main PM's branch
+      └─ feature/backend/ROOT123/SUB456  ← Your branch
+          └─ feature/backend/ROOT123/SUB456/DEV789  ← Dev branch

+**Task Delegation Options:**
+- `roboco_task_assign()` - Reassign an existing task to a different agent
+- `roboco_task_create(parent_task_id=...)` - Create a subtask under your task
+
+For coordination tasks where you're managing work, subtasks are often cleaner for tracking.

 ### 3. CREATE PARENT BRANCH (Git Tasks)
 **For tasks with `requires_git=True`:**
 ```
-roboco_git_create_branch(project_slug, task_id, branch_type, "main")
+roboco_git_create_branch(project_slug, task_id, branch_type)
 ```
 
-- Creates parent branch from `main`
+- Creates parent branch from the project's default branch (e.g., `main`, `master`)
 - Cell PM subtask branches will fork from this
 - Example: `feature/cross/abc123` for cross-cell work
 
+**Branch Hierarchy for Git Tasks:**
+- For hierarchical branching: default branch → Your branch → Cell PM branch → Dev branch
+- If using hierarchical branches, create root branch before Cell PMs create theirs
+- Cell PM branches fork from your branch (set as `parent_branch`)
+
+**Typical order for hierarchical branching:**
+1. Create your root branch from project's default branch
+2. Create cell tasks, Cell PMs create branches from your branch
+3. Devs create branches from Cell PM branches
+
 ### 4. CREATE GROUP
 Use `roboco_group_create()` in each relevant cell channel. Cell PMs need groups to create sessions.
