+# Task ID: 53
+# Title: Implement Subtask Suggestion Feature for Parent Tasks
+# Status: pending
+# Dependencies: None
+# Priority: medium
+# Description: Create a new CLI command that suggests contextually relevant subtasks for existing parent tasks, allowing users to accept, decline, or regenerate suggestions before adding them to the system.
+# Details:
+Develop a new command `suggest-subtask <task-id>` that generates intelligent subtask suggestions for a specified parent task. The implementation should:
+
+1. Accept a parent task ID as input and validate it exists
+2. Gather a snapshot of all existing tasks in the system (titles only, with their statuses and dependencies)
+3. Retrieve the full details of the specified parent task
+4. Use this context to generate a relevant subtask suggestion that would logically help complete the parent task
+5. Present the suggestion to the user in the CLI with options to:
+   - Accept (a): Add the subtask to the system under the parent task
+   - Decline (d): Reject the suggestion without adding anything
+   - Regenerate (r): Generate a new alternative subtask suggestion
+   - Edit (e): Accept but allow editing the title/description before adding
+
+The suggestion algorithm should consider:
+- The parent task's description and requirements
+- Current progress (% complete) of the parent task
+- Existing subtasks already created for this parent
+- Similar patterns from other tasks in the system
+- Logical next steps based on software development best practices
+
+When a subtask is accepted, it should be properly linked to the parent task and assigned appropriate default values for priority and status.
+
+# Test Strategy:
+Testing should verify both the functionality and the quality of suggestions:
+
+1. Unit tests:
+   - Test command parsing and validation of task IDs
+   - Test snapshot creation of existing tasks
+   - Test the suggestion generation with mocked data
+   - Test the user interaction flow with simulated inputs
+
+2. Integration tests:
+   - Create a test parent task and verify subtask suggestions are contextually relevant
+   - Test the accept/decline/regenerate workflow end-to-end
+   - Verify proper linking of accepted subtasks to parent tasks
+   - Test with various types of parent tasks (frontend, backend, documentation, etc.)
+
+3. Quality assessment:
+   - Create a benchmark set of 10 diverse parent tasks
+   - Generate 3 subtask suggestions for each and have team members rate relevance on 1-5 scale
+   - Ensure average relevance score exceeds 3.5/5
+   - Verify suggestions don't duplicate existing subtasks
+
+4. Edge cases:
+   - Test with a parent task that has no description
+   - Test with a parent task that already has many subtasks
+   - Test with a newly created system with minimal task history
