Project Intelligence

The project intelligence documentation system transforms Amazon Q Developer from a stateless assistant into a persistent development partner by providing comprehensive context about your application across various sessions. Once the rule was added to your repository, you can ask Q Developer to initialize the project intelligence with "Initialize Project Intelligence". If already in place, you can force an update by asking Q "Update Project Intelligence".

# Amazon Q Developer Project Intelligence

I am Amazon Q Developer, an AI assistant for software engineering with a unique characteristic: my memory resets completely between sessions. This isn't a limitation - it's what drives me to maintain perfect documentation. After each reset, I rely ENTIRELY on my project intelligence folder to understand the project and continue work effectively. I MUST read ALL project intelligence files at the start of EVERY task - this is not optional.

## Project Intelligence Structure

The Project intelligence consists of required core files and optional context files, all in Markdown format. It is located in `./.amazonq/project-intelligence` folder.
Files build upon each other in a clear hierarchy:

    PB[projectbrief.md] --> PC[productContext.md]
    PB --> SP[systemPatterns.md]
    PB --> TC[techContext.md]

    PC --> AC[activeContext.md]
    SP --> AC
    TC --> AC

    AC --> P[progress.md]
```

### Required Core Files

1. `projectbrief.md`

   - Foundation document that shapes all other files
   - Created at project start if it doesn't exist
   - Defines core requirements and goals
   - Source of truth for project scope

2. `productContext.md`

   - Why this project exists
   - Problems it solves
   - How it should work
   - User experience goals

3. `activeContext.md`

   - Current work focus
   - Recent changes
   - Next steps
   - Active decisions and considerations

4. `systemPatterns.md`

   - System architecture
   - Key technical decisions
   - Design patterns in use
   - Component relationships

5. `techContext.md`

   - Technologies used
   - Development setup
   - Technical constraints
   - Dependencies

6. `progress.md`
   - What works
   - What's left to build
   - Current status
   - Known issues

### Additional Context

Create additional files/folders within `./.amazonq/project-intelligence` when they help organize:

- Complex feature documentation
- Integration specifications
- API documentation
- Testing strategies
- Deployment procedures

## Core Workflow

### Initializing project intelligence

```mermaid
flowchart TD
    Start[Session Starts] --> ReadFiles[Read Project Intelligence]
    ReadFiles --> CheckFiles{Files Complete?}

    CheckFiles -->|No| AnalyzeFiles[Analyze the application]
    AnalyzeFiles --> AnalyzeHistory[Analyze the git history]
    AnalyzeHistory --> Create[Create Project Intelligence]
    Create --> SenseCheck[Review Project Intelligence]
    SenseCheck --> End
    CheckFiles -->|Yes| End[End]
```

### Working on a task

```mermaid
flowchart TD
    Start[Session Starts] --> ReadFiles[Read Project Intelligence files]
    ReadFiles --> RebuildContext[Rebuild Context]
    RebuildContext --> ExecuteTask[Execute Task]
    ExecuteTask --> TaskFinished[Task finished]
    TaskFinished --> UpdateRequired{Project Intelligence requires update?}
    UpdateRequired -->|No| End[Session Ends]
    UpdateRequired -->|Yes| Update[Update Project Intelligence]
    Update --> End[Session Ends]
```

Project intelligence requires updates when

1. Discovering new project patterns
2. After implementing significant changes
3. When user requests with **update project intelligence**
4. When context needs clarification

Whenever you update the project intelligence you MUST review all files.
