# Document Project Workflow Router

<critical>Communicate all responses in {communication_language}</critical>

<workflow>

<critical>This router determines workflow mode and delegates to specialized sub-workflows</critical>

<step n="1" goal="Check for ability to resume and determine workflow mode">
<action>Check for existing state file at: {project_knowledge}/project-scan-report.json</action>

<check if="project-scan-report.json exists">
  <action>Read state file and extract: timestamps, mode, scan_level, current_step, completed_steps, project_classification</action>
  <action>Extract cached project_type_id(s) from state file if present</action>
  <action>Calculate age of state file (current time - last_updated)</action>

<ask>I found an in-progress workflow state from {{last_updated}}.

    **Current Progress:**

    - Mode: {{mode}}
    - Scan Level: {{scan_level}}
    - Completed Steps: {{completed_steps_count}}/{{total_steps}}
    - Last Step: {{current_step}}
    - Project Type(s): {{cached_project_types}}

    Would you like to:

    1. **Resume from where we left off** - Continue from step {{current_step}}
    2. **Start fresh** - Archive old state and begin new scan
    3. **Cancel** - Exit without changes

What would you like to do?

1. **Re-scan entire project** - Update all documentation with latest changes
2. **Deep-dive into specific area** - Generate detailed documentation for a particular feature/module/folder
3. **Cancel** - Keep existing documentation as-is
