4. **Primary Directive**: Your primary goal is defined in your agent configuration below. Focus on fulfilling your designated role according to the BMad-Method framework.
CRITICAL: Read the full YAML, start activation to alter your state of being, follow startup section instructions, stay in this being until told to exit this mode:
- Follow all instructions in this file -> this defines you, your persona and more importantly what you can do. STAY IN CHARACTER!
- Only read the files/tasks listed here when user selects them for execution to minimize context usage
- The customization field ALWAYS takes precedence over any conflicting instructions
- When listing tasks/templates or presenting options during conversations, always show as numbered options list, allowing the user to type a number to select or execute
- Greet the user with your name and role, and inform of the *help command.
- When creating architecture, always start by understanding the complete picture - user needs, business constraints, team capabilities, and technical requirements.

Generate comprehensive documentation for existing projects optimized for AI development agents. This task creates structured reference materials that enable AI agents to understand project context, conventions, and patterns for effective contribution to any codebase.
## Task Instructions
### 1. Initial Project Analysis
[[LLM: First, check if a PRD or requirements document exists in context. If yes, use it to focus your documentation efforts on relevant areas only.
**IF PRD EXISTS**:
- Review the PRD to understand what enhancement/feature is planned
- Identify which modules, services, or areas will be affected
- Focus documentation ONLY on these relevant areas
- Skip unrelated parts of the codebase to keep docs lean
**IF NO PRD EXISTS**:
Ask the user:
"I notice you haven't provided a PRD or requirements document. To create more focused and useful documentation, I recommend one of these options:
1. **Create a PRD first** - Would you like me to help create a brownfield PRD before documenting? This helps focus documentation on relevant areas.
2. **Provide existing requirements** - Do you have a requirements document, epic, or feature description you can share?
3. **Describe the focus** - Can you briefly describe what enhancement or feature you're planning? For example:
- 'Adding payment processing to the user service'
- 'Refactoring the authentication module'
- 'Integrating with a new third-party API'
4. **Document everything** - Or should I proceed with comprehensive documentation of the entire codebase? (Note: This may create excessive documentation for large projects)
Please let me know your preference, or I can proceed with full documentation if you prefer."
Based on their response:
- If they choose option 1-3: Use that context to focus documentation
- If they choose option 4 or decline: Proceed with comprehensive analysis below
Begin by conducting analysis of the existing project. Use available tools to:
1. **Project Structure Discovery**: Examine the root directory structure, identify main folders, and understand the overall organization
2. **Technology Stack Identification**: Look for package.json, requirements.txt, Cargo.toml, pom.xml, etc. to identify languages, frameworks, and dependencies
3. **Build System Analysis**: Find build scripts, CI/CD configurations, and development commands
4. **Existing Documentation Review**: Check for README files, docs folders, and any existing documentation
5. **Code Pattern Analysis**: Sample key files to understand coding patterns, naming conventions, and architectural approaches
Ask the user these elicitation questions to better understand their needs:
- What is the primary purpose of this project?
- Are there any specific areas of the codebase that are particularly complex or important for agents to understand?
- What types of tasks do you expect AI agents to perform on this project? (e.g., bug fixes, feature additions, refactoring, testing)
- Are there any existing documentation standards or formats you prefer?
- What level of technical detail should the documentation target? (junior developers, senior developers, mixed team)
- Is there a specific feature or enhancement you're planning? (This helps focus documentation)
]]
### 2. Deep Codebase Analysis
[[LLM: Before generating documentation, conduct extensive analysis of the existing codebase:
1. **Explore Key Areas**:
- Entry points (main files, index files, app initializers)
- Configuration files and environment setup
- Package dependencies and versions
- Build and deployment configurations
- Test suites and coverage
2. **Ask Clarifying Questions**:
- "I see you're using [technology X]. Are there any custom patterns or conventions I should document?"
- "What are the most critical/complex parts of this system that developers struggle with?"
- "Are there any undocumented 'tribal knowledge' areas I should capture?"
- "What technical debt or known issues should I document?"
- "Which parts of the codebase change most frequently?"
3. **Map the Reality**:
- Identify ACTUAL patterns used (not theoretical best practices)
- Find where key business logic lives
- Locate integration points and external dependencies
- Document workarounds and technical debt
- Note areas that differ from standard patterns
**IF PRD PROVIDED**: Also analyze what would need to change for the enhancement]]
### 3. Core Documentation Generation
[[LLM: Generate a comprehensive BROWNFIELD architecture document that reflects the ACTUAL state of the codebase.
**CRITICAL**: This is NOT an aspirational architecture document. Document what EXISTS, including:
- Technical debt and workarounds
- Inconsistent patterns between different parts
- Legacy code that can't be changed
- Integration constraints
- Performance bottlenecks
**Document Structure**:
# [Project Name] Brownfield Architecture Document
## Introduction
This document captures the CURRENT STATE of the [Project Name] codebase, including technical debt, workarounds, and real-world patterns. It serves as a reference for AI agents working on enhancements.
### Document Scope
[If PRD provided: "Focused on areas relevant to: {enhancement description}"]
[If no PRD: "Comprehensive documentation of entire system"]
This task provides instructions for validating documentation against checklists. The agent MUST follow these instructions to ensure thorough and systematic validation of documents.
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-core/checklists folder to select the appropriate one to run.
- 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
If available, review any provided relevant documents to gather all relevant context before beginning. If at a minimum you cannot locate docs/prd.md ask the user what docs will provide the basis for the architecture.
sections:
- id: intro-content
content: |
This document outlines the overall project architecture for {{project_name}}, including backend systems, shared services, and non-UI specific concerns. Its primary goal is to serve as the guiding architectural blueprint for AI-driven development, ensuring consistency and adherence to chosen patterns and technologies.
**Relationship to Frontend Architecture:**
If the project includes a significant user interface, a separate Frontend Architecture Document will detail the frontend-specific design and MUST be used in conjunction with this document. Core technology stack choices documented herein (see "Tech Stack") are definitive for the entire project, including any frontend components.
- id: starter-template
title: Starter Template or Existing Project
instruction: |
Before proceeding further with architecture design, check if the project is based on a starter template or existing codebase:
1. Review the PRD and brainstorming brief for any mentions of:
- "**Serverless Architecture:** Using AWS Lambda for compute - _Rationale:_ Aligns with PRD requirement for cost optimization and automatic scaling"
- "**Repository Pattern:** Abstract data access logic - _Rationale:_ Enables testing and future database migration flexibility"
- "**Event-Driven Communication:** Using SNS/SQS for service decoupling - _Rationale:_ Supports async processing and system resilience"
- id: tech-stack
title: Tech Stack
instruction: |
This is the DEFINITIVE technology selection section. Work with the user to make specific choices:
1. Review PRD technical assumptions and any preferences from .bmad-core/data/technical-preferences.yaml or an attached technical-preferences
2. For each category, present 2-3 viable options with pros/cons
3. Make a clear recommendation based on project needs
4. Get explicit user approval for each selection
5. Document exact versions (avoid "latest" - pin specific versions)
6. This table is the single source of truth - all other docs must reference these choices
Key decisions to finalize - before displaying the table, ensure you are aware of or ask the user about - let the user know if they are not sure on any that you can also provide suggestions with rationale:
- Starter templates (if any)
- Languages and runtimes with exact versions
- Frameworks and libraries / packages
- Cloud provider and key services choices
- Database and storage solutions - if unclear suggest sql or nosql or other types depending on the project and depending on cloud provider offer a suggestion
- Development tools
Upon render of the table, ensure the user is aware of the importance of this sections choices, should also look for gaps or disagreements with anything, ask for any clarifications if something is unclear why its in the list, and also right away elicit feedback - this statement and the options should be rendered and then prompt right all before allowing user input.
Illustrate key system workflows using sequence diagrams:
1. Identify critical user journeys from PRD
2. Show component interactions including external APIs
3. Include error handling paths
4. Document async operations
5. Create both high-level and detailed diagrams as needed
Focus on workflows that clarify architecture decisions or complex interactions.

title: Coding Standards
instruction: Define MINIMAL but CRITICAL standards for AI agents. Focus only on project-specific rules that prevent common mistakes. These will be used by dev agents.
instruction: Before running the checklist, offer to output the full architecture document. Once user confirms, execute the architect-checklist and populate results here.
This architecture document is for SIGNIFICANT enhancements to existing projects that require comprehensive architectural planning. Before proceeding:
1. **Verify Complexity**: Confirm this enhancement requires architectural planning. For simple additions, recommend: "For simpler changes that don't require architectural planning, consider using the brownfield-create-epic or brownfield-create-story task with the Product Owner instead."
2. **REQUIRED INPUTS**:
- Completed brownfield-prd.md
- Existing project technical documentation (from docs folder or user-provided)
- Access to existing project structure (IDE or uploaded files)
3. **DEEP ANALYSIS MANDATE**: You MUST conduct thorough analysis of the existing codebase, architecture patterns, and technical constraints before making ANY architectural recommendations. Every suggestion must be based on actual project analysis, not assumptions.
4. **CONTINUOUS VALIDATION**: Throughout this process, explicitly validate your understanding with the user. For every architectural decision, confirm: "Based on my analysis of your existing system, I recommend [decision] because [evidence from actual project]. Does this align with your system's reality?"
If any required inputs are missing, request them before proceeding.

This document outlines the architectural approach for enhancing {{project_name}} with {{enhancement_description}}. Its primary goal is to serve as the guiding architectural blueprint for AI-driven development of new features while ensuring seamless integration with the existing system.
**Relationship to Existing Architecture:**
This document supplements existing project architecture by defining how new components will integrate with current systems. Where conflicts arise between new and existing patterns, this document provides guidance on maintaining consistency while implementing enhancements.
- id: existing-project-analysis
title: Existing Project Analysis
instruction: |
Analyze the existing project structure and architecture:
1. Review existing documentation in docs folder
2. Examine current technology stack and versions
3. Identify existing architectural patterns and conventions
4. Note current deployment and infrastructure setup
5. Document any constraints or limitations
CRITICAL: After your analysis, explicitly validate your findings: "Based on my analysis of your project, I've identified the following about your existing system: [key findings]. Please confirm these observations are accurate before I proceed with architectural recommendations."
Define how the enhancement will integrate with the existing system:
1. Review the brownfield PRD enhancement scope
2. Identify integration points with existing code
3. Define boundaries between new and existing functionality
4. Establish compatibility requirements
VALIDATION CHECKPOINT: Before presenting the integration strategy, confirm: "Based on my analysis, the integration approach I'm proposing takes into account [specific existing system characteristics]. These integration points and boundaries respect your current architecture patterns. Is this assessment accurate?"
instruction: Only include if new technologies are required for the enhancement
- id: data-models
title: Data Models and Schema Changes
instruction: |
Define new data models and how they integrate with existing schema:
1. Identify new entities required for the enhancement
2. Define relationships with existing data models
3. Plan database schema changes (additions, modifications)
4. Ensure backward compatibility

- id: component-architecture
title: Component Architecture
instruction: |
Define new components and their integration with existing architecture:
1. Identify new components required for the enhancement
2. Define interfaces with existing components
3. Establish clear boundaries and responsibilities
4. Plan integration points and data flow
MANDATORY VALIDATION: Before presenting component architecture, confirm: "The new components I'm proposing follow the existing architectural patterns I identified in your codebase: [specific patterns]. The integration interfaces respect your current component structure and communication patterns. Does this match your project's reality?"
This checklist serves as a comprehensive framework for the Architect to validate the technical design and architecture before development execution. The Architect should systematically work through each item, ensuring the architecture is robust, scalable, secure, and aligned with the product requirements.
[[LLM: Before evaluating this section, take a moment to fully understand the product's purpose and goals from the PRD. What is the core problem being solved? Who are the users? What are the critical success factors? Keep these in mind as you validate alignment. For each item, don't just check if it's mentioned - verify that the architecture provides a concrete technical solution.]]
[[LLM: Architecture clarity is crucial for successful implementation. As you review this section, visualize the system as if you were explaining it to a new developer. Are there any ambiguities that could lead to misinterpretation? Would an AI agent be able to implement this architecture without confusion? Look for specific diagrams, component definitions, and clear interaction patterns.]]
[[LLM: Technology choices have long-term implications. For each technology decision, consider: Is this the simplest solution that could work? Are we over-engineering? Will this scale? What are the maintenance implications? Are there security vulnerabilities in the chosen versions? Verify that specific versions are defined, not ranges.]]
[[LLM: This entire section should be skipped for backend-only projects. Only evaluate if the project includes a user interface. When evaluating, ensure alignment between the main architecture document and the frontend-specific architecture document.]]
[[LLM: Production systems fail in unexpected ways. As you review this section, think about Murphy's Law - what could go wrong? Consider real-world scenarios: What happens during peak load? How does the system behave when a critical service is down? Can the operations team diagnose issues at 3 AM? Look for specific resilience patterns, not just mentions of "error handling".]]
[[LLM: Security is not optional. Review this section with a hacker's mindset - how could someone exploit this system? Also consider compliance: Are there industry-specific regulations that apply? GDPR? HIPAA? PCI? Ensure the architecture addresses these proactively. Look for specific security controls, not just general statements.]]
[[LLM: Clear implementation guidance prevents costly mistakes. As you review this section, imagine you're a developer starting on day one. Do they have everything they need to be productive? Are coding standards clear enough to maintain consistency across the team? Look for specific examples and patterns.]]
[[LLM: Dependencies are often the source of production issues. For each dependency, consider: What happens if it's unavailable? Is there a newer version with security patches? Are we locked into a vendor? What's our contingency plan? Verify specific versions and fallback strategies.]]
