Task Folder Migrator

Task Folder Migrator

Migrate single-file tasks to the new v3.0.0 folder-based structure.

Activation

Activate when:

• User says "migrate tasks to new structure"
• User says "convert task files to folders"
• User invokes /ai-dev-assistant:migrate-tasks (manual mode)
• Invoked by ai-dev-assistant:project-orchestrator when old format detected (automatic mode)
• Before upgrading from v2.x to v3.0.0

Modes

Automatic Mode (when invoked by /next command):

• No confirmation prompt
• Proceeds directly to migration
• Used when user runs /next and old format detected
• Backups protect against data loss

Manual Mode (when invoked by /migrate-tasks command):

• Shows migration plan
• Waits for user confirmation
• Used when user explicitly runs migration command

What This Does

Converts old-style single-file tasks into new folder structure:

Old Structure (v2.x):

implementation_process/in_progress/
└── settings_form.md    # Everything in one file

New Structure (v3.0.0):

implementation_process/in_progress/settings_form/
├── task.md              # Tracker with links
├── research.md          # Phase 1 content
├── architecture.md      # Phase 2 content
└── implementation.md    # Phase 3 content

Workflow

0. Detect Mode

Check if invoked automatically or manually:

• Automatic: Invoked by ai-dev-assistant:project-orchestrator agent (context includes automatic=true)
• Manual: Invoked by /migrate-tasks command or user request

Set $automatic = true/false based on invocation context.

1. Identify Project Path

Get project path from project_state.md or ask user:

Where are your task files located?
Default: {cwd}/implementation_process/in_progress/

2. Scan for Old-Style Tasks

Use Glob to find single .md files:

{project_path}/implementation_process/in_progress/*.md

If no .md files found, report: "No old-style tasks found. All tasks already using v3.0.0 structure."

3. Present Migration Plan (or Auto-Proceed)

If Automatic Mode ($automatic = true):

Show brief message and proceed immediately:

Found {N} task(s) in v2.x format.
Auto-migrating: {list of task names}

Skip to Step 4 (no confirmation needed).

If Manual Mode ($automatic = false):

Show full migration plan and wait for confirmation:

## Tasks to Migrate

Found {N} task(s) in old format:

1. settings_form.md
2. content_entity.md
3. field_formatter.md

Proceed with migration? (Creates backups with .bak extension)

Wait for user confirmation. If user declines, exit gracefully.

4. Migrate Each Task

For each task file:

A. Read Existing Content

Use Read on {task_name}.md to load full content.

B. Parse Sections

Extract content by searching for markdown headers:

• Research section: Content between ## Research or ## Phase 1 and next ## header
• Architecture section: Content between ## Architecture or ## Phase 2 and next ## header
• Implementation section: Content between ## Implementation or ## Phase 3 and next ## header
• Other sections: Goal, Acceptance Criteria, Related Tasks, Notes

C. Create Folder Structure

Use Bash to create directory:

mkdir -p "{project_path}/implementation_process/in_progress/{task_name}"

D. Write New Files

1. Create task.md (Tracker):

Use Write to create {task_name}/task.md:

# Task: {task_name}

**Created:** {original_date or today}
**Current Phase:** {detect from content}

## Goal
{extract from original Goal section}

## Phase Status
- [{x if research exists}] Phase 1: Research → See [research.md](research.md)
- [{x if architecture exists}] Phase 2: Architecture → See [architecture.md](architecture.md)
- [{x if implementation exists}] Phase 3: Implementation → See [implementation.md](implementation.md)

## Acceptance Criteria
{extract from original Acceptance Criteria section}

## Related Tasks
{extract from original Related Tasks section}

## Notes
{extract from original Notes section}

2. Create research.md (if content exists):

If Research section found, use Write to create {task_name}/research.md:

# Research: {task_name}

{paste Research section content here}

3. Create architecture.md (if content exists):

If Architecture section found, use Write to create {task_name}/architecture.md:

# Architecture: {task_name}

{paste Architecture section content here}

4. Create implementation.md (if content exists):

If Implementation section found, use Write to create {task_name}/implementation.md:

# Implementation: {task_name}

{paste Implementation section content here}

E. Backup Original

Use Bash to rename original file:

mv "{project_path}/implementation_process/in_progress/{task_name}.md" \
   "{project_path}/implementation_process/in_progress/{task_name}.md.bak"

5. Report Results

After migrating all tasks, report:

## Migration Complete ✓

Migrated {N} task(s) to v3.0.0 structure:

1. settings_form/ ✓
   - task.md
   - research.md
   - architecture.md
   - Backup: settings_form.md.bak

2. content_entity/ ✓
   - task.md
   - research.md
   - Backup: content_entity.md.bak

Original files backed up with .bak extension.

**Next Steps:**
1. Verify migrated tasks: Check {project_path}/implementation_process/in_progress/
2. Delete backups when confident: rm *.md.bak

Edge Cases

Stop Points

In Manual Mode, STOP and ask user if:

• More than 10 tasks to migrate (confirm large migration)
• Backup file already exists (overwrite?)
• Project path looks wrong

In Automatic Mode, proceed but log warnings:

• Large migration (10+ tasks): Log "Migrating {N} tasks..."
• Backup exists: Append timestamp instead of overwriting
• Project path issues: Abort migration, log error

Important Notes

• Always create backups - Users can delete them later
• Preserve all content - Don't lose any information
• Simple extraction - Just split by headers, don't rewrite
• Idempotent - Safe to run multiple times
