+- Use past tense (e.g., "Read package.json", "Fixed type error in utils.ts")
+- Be specific about what was done
+- Keep under 8 words

-## When to Use This Tool
-
-- To see what tasks are available to work on (status: 'pending', no owner, not blocked)
-- To check overall progress on the project
-- To find tasks that are blocked and need dependencies resolved
-- Before assigning tasks to teammates, to see what's available
-- After completing a task, to check for newly unblocked work or claim the next available task
-
-## Output
-
-Returns a summary of each task:
-- **id**: Task identifier (use with TaskGet, TaskUpdate, or assignTask)
-- **subject**: Brief description of the task
-- **status**: 'pending', 'in_progress', or 'completed'
-- **owner**: Agent ID if assigned, empty if available
-- **blockedBy**: List of open task IDs that must be resolved first (tasks with blockedBy cannot be claimed until dependencies resolve)
-
-Use TaskGet with a specific task ID to view full details including description and comments.
-
-## Teammate Workflow
-
-When working as a teammate:
-1. After completing your current task, call TaskList to find available work
-2. Look for tasks with status 'pending', no owner, and empty blockedBy
-3. Use claimTask to claim an available task, or wait for leader assignment
-4. If blocked, focus on unblocking tasks or notify the team lead
