 **Resume Mode**: When called with `--resume-session` flag, skips discovery phase and directly enters TodoWrite generation and agent execution for the specified session.
 
+## Performance Optimization Strategy
+
+**Lazy Loading**: Task JSONs read **on-demand** during execution, not upfront. TODO_LIST.md + IMPL_PLAN.md provide metadata for planning.
+
+| Metric | Before | After | Improvement |

 ## Core Rules
 **Complete entire workflow autonomously without user interruption, using TodoWrite for comprehensive progress tracking.**
 **Execute all discovered pending tasks sequentially until workflow completion or blocking dependency.**

-1. **Dependency Resolution**: Build execution order based on `depends_on`
+**Optimized to avoid reading all task JSONs upfront**
-2. **Status Validation**: Filter tasks with `status: "pending"` and met dependencies
+
-3. **Agent Assignment**: Determine agent type from `meta.agent` or `meta.type`
+1. **Read IMPL_PLAN.md**: Understand overall strategy, task breakdown summary, dependencies
-4. **Context Preparation**: Load dependency summaries and inherited context
+2. **Read TODO_LIST.md**: Get current task statuses and execution progress
+3. **Extract Task Metadata**: Parse task IDs, titles, and dependency relationships from TODO_LIST.md
+4. **Build Execution Queue**: Determine ready tasks based on TODO_LIST.md status and dependencies
+
+**Key Optimization**: Use IMPL_PLAN.md and TODO_LIST.md as primary sources instead of reading all task JSONs

-2. **Mark Initial Status**: Set first pending task as `in_progress`

+   - Identify first pending task with met dependencies

+4. **Validate Prerequisites**: Ensure IMPL_PLAN.md and TODO_LIST.md exist and are valid
-5. **Validate Prerequisites**: Ensure all required context is available from existing session
 
 **Resume Mode Behavior**:
-- Load existing session state directly from `.workflow/{session-id}/`
+- Load existing TODO_LIST.md directly from `.workflow/{session-id}/`
-- Use session's task files and summaries without discovery
+- Extract current progress from TODO_LIST.md
-- Generate TodoWrite from current session progress
+- Generate TodoWrite from TODO_LIST.md state
-- Proceed immediately to agent execution
+- Proceed immediately to agent execution (Phase 4)
 
-### Phase 4: Execution
+### Phase 4: Execution (Lazy Task Loading)
-1. **Pass Task with Flow Control**: Include complete task JSON with `pre_analysis` steps for agent execution
+**Key Optimization**: Read task JSON **only when needed** for execution
-2. **Launch Agent**: Invoke specialized agent with complete context including flow control steps
+
-3. **Monitor Progress**: Track agent execution and handle errors without user interruption
+1. **Identify Next Task**: From TodoWrite, get the next `in_progress` task ID
-4. **Collect Results**: Gather implementation results and outputs
+2. **Load Task JSON on Demand**: Read `.task/{task-id}.json` for current task ONLY
-5. **Continue Workflow**: Automatically proceed to next pending task until completion
+3. **Validate Task Structure**: Ensure all 5 required fields exist (id, title, status, meta, context, flow_control)
+4. **Pass Task with Flow Control**: Include complete task JSON with `pre_analysis` steps for agent execution
+5. **Launch Agent**: Invoke specialized agent with complete context including flow control steps
+6. **Monitor Progress**: Track agent execution and handle errors without user interruption
+7. **Collect Results**: Gather implementation results and outputs
+8. **Update TODO_LIST.md**: Mark current task as completed in TODO_LIST.md
+9. **Continue Workflow**: Identify next pending task from TODO_LIST.md and repeat from step 1
+
+**Execution Loop Pattern**:
+```
+while (TODO_LIST.md has pending tasks) {
+  next_task_id = getTodoWriteInProgressTask()
+  task_json = Read(.workflow/{session}/.task/{next_task_id}.json)  // Lazy load
+  executeTaskWithAgent(task_json)
+  updateTodoListMarkCompleted(next_task_id)
+  advanceTodoWriteToNextTask()

+- Reduces initial context loading by ~90%
+- Only reads task JSON when actually executing
+- Scales better for workflows with many tasks
+- Faster startup time for workflow execution
