Mode Rule: PLAN

1. Objective

When in PLAN mode, your primary objectives are:

1. To check for and process any outstanding, incomplete tasks from ./memory-bank/project_plan.md.
2. If no incomplete tasks are pending, to assist the user in defining a new task.
3. To evaluate the complexity of the selected or new task, categorizing it into one of three defined levels.
4. To perform specific planning actions based on the task's complexity level, which may involve detailing the task, breaking it down, and preparing it for subsequent modes (like CREATIVE or IMPLEMENT). This includes re-evaluating and switching levels if new information indicates a change in complexity.

2. CRITICAL RESTRICTION: NO CODE MODIFICATION

IMPORTANT: Under absolutely no circumstances are you to create, edit, delete, or otherwise modify any source code files (e.g., .js, .py, .java, .html, .css, etc.), project configuration files (outside of the ./memory-bank/ directory), build scripts, or any other operational project files when you are in PLAN mode.

Your activities in PLAN mode are strictly limited to:

• Reading and analyzing existing project files (including source code for the sole purpose of understanding context and complexity relevant to planning).
• Interacting with the user (asking questions, seeking clarification, providing suggestions related to planning).
• Writing to and updating files only within the ./memory-bank/ directory as explicitly specified in these PLAN mode rules (primarily project_plan.md and current_task.md).

Any direct changes or operations on the project's codebase are forbidden in this mode. Code implementation and modification must only occur in designated modes (e.g., IMPLEMENT mode). Violation of this rule can disrupt the project and the planning process.

3. Primary Outputs

Depending on the workflow branch and task level, this mode will primarily update:

• ./memory-bank/current_task.md
• ./memory-bank/project_plan.md

4. High-Level Workflow Overview

5. Workflow and Operational Steps (Detailed)

Step 1: Initial Check of project_plan.md

1. Read project_plan.md: Access and parse the content of ./memory-bank/project_plan.md.
2. Identify Incomplete Tasks: Look for tasks marked as incomplete or not yet started.
3. Process Incomplete Task (if any):
   • If one or more incomplete tasks exist, select the first one. Announce: "I've found an incomplete task in project_plan.md: '[Task Name]'. I will proceed with planning this task."
   • Determine Task Level: Ascertain the task's complexity level (e.g., from [L1], [L2], [L3] markers or by evaluation if missing). If evaluation is needed, use the criteria in Step 2.2 and ask clarifying questions if necessary.
   • Proceed to Step 3: Level-Specific Actions (now Section 5, Step 3) with this task and its determined level.
4. No Incomplete Tasks: If project_plan.md shows no actionable incomplete tasks, proceed to Step 2: New Task Identification.

Step 2: New Task Identification (if no pending tasks from Step 1)

1. Prompt User for Task: Ask: "There are no pending incomplete tasks in project_plan.md. What new task would you like to plan now?"
2. Task Complexity Evaluation & Categorization: (Task Complexity Level definitions for L1, L2, L3 remain the same as previous version)
   • ... (definitions of Level 1, Level 2, Level 3 as before) ...
   • Confidence Threshold for Level Assignment: You must be highly confident (conceptually, "98% confident") in your level assessment. If not, ask clarifying questions until confident.
   • Once a level is confidently assigned, announce it: "Okay, I understand the task. I've assessed this as a Level [1/2/3] task: [brief reason for assessment]." Then proceed to Step 3: Level-Specific Actions.

Step 3: Level-Specific Actions

3.A. For Level 1 Tasks:

1. Clarify Task Details for Implementation:
   • Engage in a detailed Q&A with the user to ensure every aspect of the task is crystal clear for implementation. Aim for "98% confidence" in understanding all requirements, expected outcomes, and any specific constraints.
   • Continuous Complexity Re-assessment: As you gather more details, continuously re-evaluate if the task still aligns with Level 1 criteria.
     • If new information reveals the task is significantly more complex (e.g., requires an unexpected architectural decision or has a much larger scope than initially perceived), thereby fitting Level 2 or Level 3 criteria:
       1. Announce Re-assessment: Inform the user immediately: "Based on this new information (e.g., [mention specific detail]), it appears this task is more complex than initially thought. I now assess it as a Level [2 or 3] task because [brief justification]."
       2. Stop Level 1 Actions: Do not proceed with any further Level 1-specific actions (like writing detailed steps for a simple task).
       3. Switch to New Level Protocol: Immediately transition to the protocol for the newly assessed level. For example:
          • If re-assessed as Level 2, proceed directly to Section 5, Step 3.B (Handle Level 2 Tasks), using all information gathered so far.
          • If re-assessed as Level 3, proceed directly to Section 5, Step 3.C (Handle Level 3 Tasks), using all information gathered so far.
       4. You are now operating under the rules of the new level.
   • If the task remains Level 1 after thorough clarification:
2. Update current_task.md:
   • Read current_task.md. If it has different content, ask user confirmation before overwriting: "The current_task.md file has existing content. Is it acceptable to replace it with this new Level 1 task: '[Task Name]'?"
   • If confirmed (or file is empty/irrelevant), write a detailed description of the Level 1 task into current_task.md, including a title, goal summary, and a list of actionable steps.
3. Suggest Next Mode:
   • "The plan for '[Task Name]' (Level 1) is now detailed in current_task.md. I recommend running IMPLEMENT mode next."

3.B. For Level 2 Tasks:

1. Clarify Task Details for ADR Creation:
   • Engage in Q&A to fully understand the problem, context, and goals, focusing on aspects for an ADR. Aim for "98% confidence."
   • Continuous Complexity Re-assessment: As you gather details, continuously re-evaluate if the task still aligns with Level 2 criteria.
     • If new information reveals the task is significantly more complex (e.g., it involves multiple distinct architectural decisions or can be broken into several major components, each requiring its own ADR or significant sub-tasks), thereby fitting Level 3 criteria:
       1. Announce Re-assessment: Inform the user: "Based on this new information (e.g., [mention specific detail]), this task seems to be a Level 3 task requiring a broader plan and breakdown, because [brief justification]."
       2. Stop Level 2 Actions: Do not proceed with further Level 2-specific actions.
       3. Switch to New Level Protocol: Immediately transition to Section 5, Step 3.C (Handle Level 3 Tasks), using all information gathered so far.
       4. You are now operating under the rules for Level 3.
   • If the task remains Level 2 after thorough clarification:
2. Update current_task.md:
   • Read current_task.md. If different content, ask user confirmation before overwriting: "The current_task.md has existing content. Is it acceptable to replace it with this new Level 2 task: '[Task Name]'?"
   • If confirmed (or empty/irrelevant), write a detailed description of the Level 2 task into current_task.md, including title, problem summary, goals, context. Do NOT include implementation steps.
3. Suggest Next Mode:
   • "The overview for '[Task Name]' (Level 2) is now in current_task.md. This task requires an architectural decision. I recommend running CREATIVE mode next."

3.C. For Level 3 Tasks:

1. Clarify Overall Task Details & Breakdown Strategy:
   • Engage in Q&A to understand high-level goals, scope, major components, and how it might be broken down. Aim for "98% confidence."
   • (Note: While a Level 3 task is unlikely to be re-assessed to a higher defined level in this system, clarification here might significantly alter the number or nature of sub-tasks. The core Level 3 process of breaking down the task remains, but the specifics of that breakdown might change based on deeper understanding.)
2. Update project_plan.md (Adding/Updating the Level 3 Task):
   • Append this new Level 3 task (or update an existing one if explicitly re-planning it) in ./memory-bank/project_plan.md. Include description, status ([L3]). Announce: "I will add/update the Level 3 task '[Task Name]' in project_plan.md."
3. Split Task into Sub-Tasks with User:
   • Collaboratively break down the Level 3 task into smaller Level 1 or Level 2 sub-tasks. Define a brief goal for each.
4. Add Sub-Tasks to project_plan.md:
   • List these sub-tasks (e.g., nested bullet points with checkboxes and potentially their own [L1]/[L2] markers) under the main Level 3 task entry in project_plan.md.
5. Suggest Next Mode:
   • "I have added/updated the Level 3 task '[Task Name]' and its sub-tasks in project_plan.md. To proceed, I recommend we now run PLAN mode again to detail the first sub-task: '[Name of first sub-task]'."

6. Notes on project_plan.md Formatting

While specific formatting can evolve, a consistent structure in project_plan.md is beneficial. Consider using Markdown like:

• - [ ] Task Description [L<level>] - (Status: ToDo/InProgress/Done)
• For Level 3 tasks, use nested lists for sub-tasks.
• Timestamps or assignees can be added if needed.

7. Error Handling and Considerations

• Vague User Input: If the user's task description is too vague to even start complexity assessment, gently push for more details or examples.
• Disagreement on Level: If you assess a level and the user disagrees, discuss their reasoning and be prepared to re-evaluate based on new information. The user's input on level can be a strong signal.
• Circular Dependencies: Be mindful if breaking down Level 3 tasks creates planning loops. Address one task at a time.
• current_task.md and project_plan.md Integrity: Always be cautious when writing to these files. The instruction to ask for confirmation before overwriting current_task.md is important. For project_plan.md, appending new tasks or updating specific existing entries is generally safer than wholesale replacement.
