execute	Execute tasks with appropriate agents and context-aware orchestration	task-id

Command Overview: /task:execute

Purpose: Executes tasks using intelligent agent selection, context preparation, and progress tracking.

Execution Modes

• auto (Default)
  • Fully autonomous execution with automatic agent selection.
  • Provides progress updates at each checkpoint.
  • Automatically completes the task when done.
• guided
  • Executes step-by-step, requiring user confirmation at each checkpoint.
  • Allows for dynamic adjustments and manual review during the process.
• review
  • Optional manual review using @universal-executor.
  • Used only when explicitly requested by user.

Agent Selection Logic

The system determines the appropriate agent for a task using the following logic.

FUNCTION select_agent(task, agent_override):
    // A manual override always takes precedence.
    // Corresponds to the --agent=<agent-type> flag.
    IF agent_override IS NOT NULL:
        RETURN agent_override

    // If no override, select based on keywords in the task title.
    ELSE:
        CASE task.title:
            WHEN CONTAINS "Build API", "Implement":
                RETURN "@code-developer"
            WHEN CONTAINS "Design schema", "Plan":
                RETURN "@planning-agent"
            WHEN CONTAINS "Write tests", "Generate tests":
                RETURN "@code-developer" // type: test-gen
            WHEN CONTAINS "Execute tests", "Fix tests", "Validate":
                RETURN "@test-fix-agent" // type: test-fix
            WHEN CONTAINS "Review code":
                RETURN "@universal-executor" // Optional manual review
            DEFAULT:
                RETURN "@code-developer" // Default agent
        END CASE
END FUNCTION

Core Execution Protocol

Pre-Execution -> Execution -> Post-Execution

Pre-Execution Protocol

Validate Task & Dependencies -> Prepare Execution Context -> Coordinate with TodoWrite

• Validation: Checks for the task's JSON file in .task/ and resolves its dependencies.
• Context Preparation: Loads task and workflow context, preparing it for the selected agent.
• Session Context Injection: Provides workflow directory paths to agents for TODO_LIST.md and summary management.
• TodoWrite Coordination: Generates execution Todos and checkpoints, syncing with TODO_LIST.md.

Post-Execution Protocol

Update Task Status -> Generate Summary -> Save Artifacts -> Sync All Progress -> Validate File Integrity

• Updates status in the task's JSON file and TODO_LIST.md.
• Creates a summary in .summaries/.
• Stores outputs and syncs progress across the entire workflow session.

Task & Subtask Execution Logic

This logic defines how single, multiple, or parent tasks are handled.

FUNCTION execute_task_command(task_id, mode, parallel_flag):
    // Handle parent tasks by executing their subtasks.
    IF is_parent_task(task_id):
        subtasks = get_subtasks(task_id)
        EXECUTE_SUBTASK_BATCH(subtasks, mode)

    // Handle wildcard execution (e.g., IMPL-001.*)
    ELSE IF task_id CONTAINS "*":
        subtasks = find_matching_tasks(task_id)
        IF parallel_flag IS true:
            EXECUTE_IN_PARALLEL(subtasks)
        ELSE:
            FOR each subtask in subtasks:
                EXECUTE_SINGLE_TASK(subtask, mode)
  
    // Default case for a single task ID.
    ELSE:
        EXECUTE_SINGLE_TASK(task_id, mode)
END FUNCTION

Error Handling & Recovery Logic

FUNCTION pre_execution_check(task):
    // Ensure dependencies are met before starting.
    IF task.dependencies ARE NOT MET:
        LOG_ERROR("Cannot execute " + task.id)
        LOG_INFO("Blocked by: " + unmet_dependencies)
        HALT_EXECUTION()

FUNCTION on_execution_failure(checkpoint):
    // Provide user with recovery options upon failure.
    LOG_WARNING("Execution failed at checkpoint " + checkpoint)
    PRESENT_OPTIONS([
        "Retry from checkpoint",
        "Retry from beginning",
        "Switch to guided mode",
        "Abort execution"
    ])
    AWAIT user_input
    // System performs the selected action.
END FUNCTION

Agent-Specific Context

Different agents receive context tailored to their function, including implementation details:

@code-developer:

• Complete implementation.files array with file paths and locations
• original_code snippets and proposed_changes for precise modifications
• logic_flow diagrams for understanding data flow
• Dependencies and affected modules for integration planning
• Performance and error handling considerations

@planning-agent:

• High-level requirements, constraints, success criteria
• Implementation risks and mitigation strategies
• Architecture implications from implementation.context_notes

@test-fix-agent:

• Test files to execute from task.context.focus_paths
• Source files to fix from implementation.files[].path
• Expected behaviors from implementation.modifications.logic_flow
• Error conditions to validate from implementation.context_notes.error_handling
• Performance requirements from implementation.context_notes.performance_considerations

@universal-executor:

• Used for optional manual reviews when explicitly requested
• Code quality standards and implementation patterns
• Security considerations from implementation.context_notes.risks
• Dependency validation from implementation.context_notes.dependencies
• Architecture compliance checks

Simplified File Output

• Task JSON File (.task/<task-id>.json): Updated with status and last attempt time only.
