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 /drupal-dev-framework:migrate-tasks (manual mode)
• Invoked by 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 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

Situation	Handling
No sections found	Create task.md only with all content
Task already migrated	Skip, report "already v3.0.0 format"
Empty sections	Don't create file for that phase
Backup file exists	Append timestamp: {task}.md.bak.{timestamp}
Permission error	Report error, skip task, continue

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

Example Output

Migrating: settings_form.md

Creating: settings_form/
  ✓ task.md (tracker with links)
  ✓ research.md (Phase 1 content)
  ✓ architecture.md (Phase 2 content)
  ✗ implementation.md (no content found)

Backup: settings_form.md → settings_form.md.bak
