+# /execute-checklist Task
+
+When this command is used, execute the following task:
+
+<!-- Powered by BMAD™ Core -->
+
+# Checklist Validation Task
+
+This task provides instructions for validating documentation against checklists. The agent MUST follow these instructions to ensure thorough and systematic validation of documents.
+
+## Available Checklists
+
+If the user asks or does not specify a specific checklist, list the checklists available to the agent persona. If the task is being run not with a specific agent, tell the user to check the .bmad-creative-writing/checklists folder to select the appropriate one to run.
+
+## Instructions
+
+1. **Initial Assessment**
+   - If user or the task being run provides a checklist name:
+     - Try fuzzy matching (e.g. "architecture checklist" -> "architect-checklist")
+     - If multiple matches found, ask user to clarify
+     - Load the appropriate checklist from .bmad-creative-writing/checklists/
+   - If no checklist specified:
+     - Ask the user which checklist they want to use
+     - Present the available options from the files in the checklists folder
+   - Confirm if they want to work through the checklist:
+     - Section by section (interactive mode - very time consuming)
+     - All at once (YOLO mode - recommended for checklists, there will be a summary of sections at the end to discuss)
+
+2. **Document and Artifact Gathering**
+   - Each checklist will specify its required documents/artifacts at the beginning
+   - Follow the checklist's specific instructions for what to gather, generally a file can be resolved in the docs folder, if not or unsure, halt and ask or confirm with the user.
+
+3. **Checklist Processing**
+
+   If in interactive mode:
+   - Work through each section of the checklist one at a time
+   - For each section:
+     - Review all items in the section following instructions for that section embedded in the checklist
+     - Check each item against the relevant documentation or artifacts as appropriate
+     - Present summary of findings for that section, highlighting warnings, errors and non applicable items (rationale for non-applicability).
+     - Get user confirmation before proceeding to next section or if any thing major do we need to halt and take corrective action
+
+   If in YOLO mode:
+   - Process all sections at once
+   - Create a comprehensive report of all findings
+   - Present the complete analysis to the user
+
+4. **Validation Approach**
+
+   For each checklist item:
+   - Read and understand the requirement
+   - Look for evidence in the documentation that satisfies the requirement
+   - Consider both explicit mentions and implicit coverage
+   - Aside from this, follow all checklist llm instructions
+   - Mark items as:
+     - ✅ PASS: Requirement clearly met
+     - ❌ FAIL: Requirement not met or insufficient coverage
+     - ⚠️ PARTIAL: Some aspects covered but needs improvement
+     - N/A: Not applicable to this case
+
+5. **Section Analysis**
+
+   For each section:
+   - think step by step to calculate pass rate
+   - Identify common themes in failed items
+   - Provide specific recommendations for improvement
+   - In interactive mode, discuss findings with user
+   - Document any user decisions or explanations
+
+6. **Final Report**
+
+   Prepare a summary that includes:
+   - Overall checklist completion status
+   - Pass rates by section
+   - List of failed items with context
+   - Specific recommendations for improvement
+   - Any sections or items marked as N/A with justification
+
+## Checklist Execution Methodology
+
+Each checklist now contains embedded LLM prompts and instructions that will:
+
+1. **Guide thorough thinking** - Prompts ensure deep analysis of each section
+2. **Request specific artifacts** - Clear instructions on what documents/access is needed
+3. **Provide contextual guidance** - Section-specific prompts for better validation
+4. **Generate comprehensive reports** - Final summary with detailed findings
+
+The LLM will:
+
+- Execute the complete checklist validation
+- Present a final report with pass/fail rates and key findings
+- Offer to provide detailed analysis of any section, especially those with warnings or failures
