Prompt-Driven Development

Overview

This sop guides you through the process of transforming a rough idea into a detailed design document with an implementation plan and todo list. It follows the Prompt-Driven Development methodology to systematically refine your idea, conduct necessary research, create a comprehensive design, and develop an actionable implementation plan. The process is designed to be iterative, allowing movement between requirements clarification and research as needed.

Parameters

• rough_idea (required): The initial concept or idea you want to develop into a detailed design

Session Context:

• The session's plan directory is automatically provided via __session__.plan_dir
• All artifacts will be stored in the session's plan directory structure

Constraints for parameter acquisition:

• You MUST ask for all required parameters upfront in a single prompt rather than one at a time
• You MUST support multiple input methods including:
  • Direct input: Text provided directly in the conversation
  • File path: Path to a local file containing the rough idea
  • URL: Link to an internal resource (e.g., Quip doc, wiki page)
  • Other methods: You SHOULD be open to other ways the user might want to provide the idea
• You MUST use appropriate tools to access content based on the input method
• You MUST confirm successful acquisition of all parameters before proceeding
• You SHOULD save the acquired rough idea to a consistent location for use in subsequent steps

Steps

1. Create Project Structure

Set up a directory structure to organize all artifacts created during the process.

Constraints:

• You MUST use the session's plan directory provided in __session__.plan_dir
• You MUST create the following files in the plan directory:
  • __session__.plan_dir/rough-idea.md (containing the provided rough idea)
  • __session__.plan_dir/idea-honing.md (for requirements clarification)
• You MUST create the following subdirectories in the plan directory:
  • __session__.plan_dir/research/ (directory for research notes)
  • __session__.plan_dir/design/ (directory for design documents)
  • __session__.plan_dir/implementation/ (directory for implementation plans)
• You MUST notify the user when the structure has been created
• You SHOULD explain that all artifacts are stored in the session's plan directory for organization

2. Initial Process Planning

Determine the initial approach and sequence for requirements clarification and research.

Constraints:

• You MUST ask the user if they prefer to:
  • Start with requirements clarification (default)
  • Start with preliminary research on specific topics
  • Provide additional context or information before proceeding
• You MUST adapt the subsequent process based on the user's preference
• You MUST explain that the process is iterative and the user can move between requirements clarification and research as needed
• You MUST wait for explicit user direction before proceeding to any subsequent step
• You MUST NOT automatically proceed to requirements clarification or research without user confirmation because this could lead the process in a direction the user doesn't want

3. Requirements Clarification

Guide the user through a series of questions to refine the initial idea and develop a thorough specification.

Constraints:

• You MUST create an empty __session__.plan_dir/idea-honing.md file if it doesn't already exist
• You MUST ask ONLY ONE question at a time and wait for the user's response before asking the next question
• You MUST NOT list multiple questions for the user to answer at once because this overwhelms users and leads to incomplete responses
• You MUST NOT pre-populate answers to questions without user input because this assumes user preferences without confirmation
• You MUST NOT write multiple questions and answers to the idea-honing.md file at once because this skips the interactive clarification process
• You MUST follow this exact process for each question:
  1. Formulate a single question
  2. Append the question to __session__.plan_dir/idea-honing.md
  3. Present the question to the user in the conversation
  4. Wait for the user's complete response, which may require brief back-and-forth dialogue across multiple turns.
  5. Once you have their complete response, append the user's answer (or final decision) to __session__.plan_dir/idea-honing.md
  6. Only then proceed to formulating the next question
• You MAY suggest possible answers when asking a question, but MUST wait for the user's actual response
• You MUST format the idea-honing.md document with clear question and answer sections
• You MUST include the final chosen answer in the answer section
• You MAY include alternative options that were considered before the final decision
• You MUST ensure you have the user's complete response before recording it and moving to the next question
• You MUST continue asking questions until sufficient detail is gathered
• You SHOULD ask about edge cases, user experience, technical constraints, and success criteria
• You SHOULD adapt follow-up questions based on previous answers
• You MAY suggest options when the user is unsure about a particular aspect
• You MAY recognize when the requirements clarification process appears to have reached a natural conclusion
• You MUST explicitly ask the user if they feel the requirements clarification is complete before moving to the next step
• You MUST offer the option to conduct research if questions arise that would benefit from additional information
• You MUST be prepared to return to requirements clarification after research if new questions emerge
• You MUST NOT proceed with any other steps until explicitly directed by the user because this could skip important clarification steps

4. Research Relevant Information

Conduct research on relevant technologies, libraries, or existing code that could inform the design, while collaborating with the user for guidance.

Constraints:

• You MUST identify areas where research is needed based on the requirements
• You MUST propose an initial research plan to the user, listing topics to investigate
• You MUST ask the user for input on the research plan, including:
  • Additional topics that should be researched
  • Specific resources (files, websites, internal tools) the user recommends
  • Areas where the user has existing knowledge to contribute
• You MUST incorporate user suggestions into the research plan
• You MUST document research findings in separate markdown files in the __session__.plan_dir/research/ directory
• You SHOULD organize research by topic (e.g., __session__.plan_dir/research/existing-code.md, __session__.plan_dir/research/technologies.md)
• You MUST include mermaid diagrams when documenting system architectures, data flows, or component relationships in research
• You MUST include links to relevant references and sources when research is based on external materials (websites, documentation, articles, etc.)
• You MAY use tools like search_internal_code, read_internal_website, or fs_read to gather information
• You MUST ask the user whether other available search tools should also be used.
• You MUST periodically check with the user during the research process (these check-ins may involve brief dialogue to clarify feedback) to:
  • Share preliminary findings
  • Ask for feedback and additional guidance
  • Confirm if the research direction remains valuable
• You MUST summarize key findings that will inform the design
• You SHOULD cite sources and include relevant links in research documents
• You MUST ask the user if the research is sufficient before proceeding to the next step
• You MUST offer to return to requirements clarification if research uncovers new questions or considerations
• You MUST NOT automatically return to requirements clarification after research without explicit user direction because this could disrupt the user's intended workflow
• You MUST wait for the user to decide the next step after completing research

5. Iteration Checkpoint

Determine if further requirements clarification or research is needed before proceeding to design.

Constraints:

• You MUST summarize the current state of requirements and research to help the user make an informed decision
• You MUST explicitly ask the user if they want to:
  • Proceed to creating the detailed design
  • Return to requirements clarification based on research findings
  • Conduct additional research based on requirements
• You MUST support iterating between requirements clarification and research as many times as needed
• You MUST ensure that both the requirements and research are sufficiently complete before proceeding to design
• You MUST NOT proceed to the design step without explicit user confirmation because this could skip important refinement steps

6. Create Detailed Design

Develop a comprehensive design document based on the requirements and research.

Constraints:

• You MUST create a detailed design document at __session__.plan_dir/design/detailed-design.md
• You MUST write the design as a standalone document that can be understood without reading other project files
• You MUST include the following sections in the design document:
  • Overview
  • Detailed Requirements (consolidated from idea-honing.md)
  • Architecture Overview
  • Components and Interfaces
  • Data Models
  • Error Handling
  • Testing Strategy
  • Appendices (Technology Choices, Research Findings, Alternative Approaches)
• You MUST consolidate all requirements from the idea-honing.md file into the Detailed Requirements section
• You MUST include an appendix section that summarizes key research findings, including:
  • Major technology choices with pros and cons
  • Existing solutions analysis
  • Alternative approaches considered
  • Key constraints and limitations identified during research
• You SHOULD include diagrams or visual representations when appropriate using mermaid syntax
• You MUST generate mermaid diagrams for architectural overviews, data flow, and component relationships
• You MUST ensure the design addresses all requirements identified during the clarification process
• You SHOULD highlight design decisions and their rationales, referencing research findings where applicable
• You MUST review the design with the user and iterate based on feedback
• You MUST offer to return to requirements clarification or research if gaps are identified during design

7. Develop Implementation Plan

Create a structured implementation plan with a series of steps for implementing the design.

Constraints:

• You MUST create an implementation plan at __session__.plan_dir/implementation/plan.md
• You MUST include a checklist at the beginning of the plan.md file to track implementation progress
• You MUST use the following specific instructions when creating the implementation plan:

  Convert the design into a series of implementation steps that will build each component in a test-driven manner following agile best practices. Each step must result in a working, demoable increment of functionality. Prioritize best practices, incremental progress, and early testing, ensuring no big jumps in complexity at any stage. Make sure that each step builds on the previous steps, and ends with wiring things together. There should be no hanging or orphaned code that isn't integrated into a previous step.
  

• You MUST format the implementation plan as a numbered series of detailed steps
• Each step in the plan MUST be written as a clear implementation objective
• Each step MUST begin with "Step N:" where N is the sequential number
• You MUST ensure each step includes:
  • A clear objective
  • General implementation guidance
  • Test requirements where appropriate
  • How it integrates with previous work
  • Demo - explicit description of the working functionality that can be demonstrated after completing this step
• You MUST ensure each step results in working, demoable functionality that provides value
• You MUST sequence steps so that core end-to-end functionality is available as early as possible
• You MUST NOT include excessive implementation details that are already covered in the design document because this creates redundancy and potential inconsistencies
• You MUST assume that all context documents (requirements, design, research) will be available during implementation
• You MUST break down the implementation into a series of discrete, manageable steps
• You MUST ensure each step builds incrementally on previous steps
• You SHOULD prioritize test-driven development where appropriate
• You MUST ensure the plan covers all aspects of the design
• You SHOULD sequence steps to validate core functionality early
• You MUST ensure the checklist items correspond directly to the steps in the implementation plan

8. Summarize and Present Results

Provide a summary of all artifacts created and next steps.

Constraints:

• You MUST create a summary document at __session__.plan_dir/summary.md
• You MUST list all artifacts created during the process
• You MUST provide a brief overview of the design and implementation plan
• You MUST suggest next steps for the user
• You SHOULD highlight any areas that may need further refinement
• You MUST present this summary to the user in the conversation

9. Offer Ralph Integration

After completing the planning process, offer to create a PROMPT.md file for Ralph.

Constraints:

• You MUST ask the user: "Would you like me to create a PROMPT.md for Ralph to implement this?"
• If the user agrees, You MUST create a minimal PROMPT.md file in the project root containing:
  • A clear objective statement
  • Key requirements (bulleted list)
  • Acceptance criteria
  • Reference to the detailed design document
• The PROMPT.md should be concise (under 100 lines) - Ralph will read the detailed design
• You MUST NOT include the full design content in PROMPT.md - just reference the design file path
• If the user declines, You SHOULD acknowledge and conclude the session

Examples

Example Input

Rough idea: I want to build a feature for our team's internal tool that allows users to create and manage templates for common documents we produce. Users should be able to create, edit, and share templates, as well as use them to generate new documents with custom fields.

Example Output

# Research Phase Interaction

Based on your requirements, I've identified several areas that would benefit from research:

1. **Existing template solutions** - Understanding what's already available
2. **Storage and versioning approaches** - How to handle template versions and sharing
3. **Custom field validation patterns** - Best practices for dynamic field validation

I notice you have several additional MCP search tools available beyond the standard ones, including 'peccy web search' and other external search capabilities. Should I incorporate these additional search tools into the research process for broader coverage of template management solutions and industry best practices?

# Project Summary

I've completed the transformation of your rough idea into a detailed design with an implementation plan. Here's what was created:

## Directory Structure
- __session__.plan_dir/
  - rough-idea.md (your initial concept)
  - idea-honing.md (our Q&A requirements clarification)
  - research/
    - existing-templates.md
    - storage-options.md
    - external-solutions.md
  - design/
    - detailed-design.md
  - implementation/
    - plan.md (includes implementation checklist)
  - summary.md (this document)

## Key Design Elements
- Template management system with CRUD operations
- Role-based access control for sharing
- Versioning system for templates
- Custom fields with validation
- Document generation engine

## Implementation Approach
The implementation plan breaks down the work into 12 incremental steps, starting with core data models and building up to the complete feature set.

## Next Steps
1. Review the detailed design document at `__session__.plan_dir`/design/detailed-design.md
2. Check the implementation plan and checklist at `__session__.plan_dir`/implementation/plan.md
3. Begin implementation following the checklist in the implementation plan

Would you like me to explain any specific part of the design or implementation plan in more detail?

Troubleshooting

Requirements Clarification Stalls

If the requirements clarification process seems to be going in circles or not making progress:

• You SHOULD suggest moving to a different aspect of the requirements
• You MAY provide examples or options to help the user make decisions
• You SHOULD summarize what has been established so far and identify specific gaps
• You MAY suggest conducting research to inform requirements decisions

Research Limitations

If you cannot access needed information:

• You SHOULD document what information is missing
• You SHOULD suggest alternative approaches based on available information
• You MAY ask the user to provide additional context or documentation
• You SHOULD continue with available information rather than blocking progress

Design Complexity

If the design becomes too complex or unwieldy:

• You SHOULD suggest breaking it down into smaller, more manageable components
• You SHOULD focus on core functionality first
• You MAY suggest a phased approach to implementation
• You SHOULD return to requirements clarification to prioritize features if needed
