Task Master AI - Claude Code Integration Guide

Tagged Task Management System

Task Master uses a tagged task management system that organizes tasks into separate, isolated contexts called tags. This enables working across multiple contexts such as different features, branches, or project phases without conflicts.

Tagged System Benefits

  • Complete Context Isolation: Each tag maintains its own task numbering (starting from 1)
  • Parallel Development: Multiple features can be developed simultaneously without conflicts
  • Independent Dependencies: Task dependencies are managed within each tag context
  • Flexible Organization: Align tags with git branches, features, or project phases
  • Team Collaboration: Clear ownership and responsibility per tag context

Essential Commands

Tag Management Commands

# Tag Context Management
task-master tags                                   # List all available tags with status
task-master tags --show-metadata                  # List tags with detailed metadata
task-master add-tag <tag-name>                    # Create a new empty tag
task-master add-tag <tag-name> --description="desc" # Create tag with description
task-master add-tag --from-branch                 # Create tag from current git branch
task-master use-tag <tag-name>                    # Switch to a different tag context
task-master copy-tag <source> <target>            # Copy entire tag to create new one
task-master delete-tag <tag-name>                 # Delete tag and all its tasks
task-master rename-tag <old-name> <new-name>      # Rename an existing tag

# Tag-based Task Operations (all work within current tag context)
task-master list                                   # Show tasks in current tag
task-master next                                   # Get next task in current tag
task-master show <id>                             # View task in current tag (e.g., 1.2)
task-master add-task --prompt="description"       # Add task to current tag

Core Workflow Commands

# Project Setup
task-master init                                   # Initialize Task Master with tagged system
task-master models --setup                        # Configure AI models interactively

# Tagged PRD Workflow
task-master use-tag <tag-name>                    # Switch to tag context
task-master parse-prd .taskmaster/docs/prd-<tag>.md  # Generate tasks from PRD in current tag

# Daily Development Workflow (within current tag)
task-master list                                   # Show all tasks in current tag
task-master next                                   # Get next available task in current tag
task-master show <id>                             # View detailed task information
task-master set-status --id=<id> --status=done    # Mark task complete in current tag

# Task Management (within current tag)
task-master expand --id=<id> --research --force   # Break task into subtasks
task-master update-task --id=<id> --prompt="changes"         # Update specific task
task-master update --from=<id> --prompt="changes"            # Update multiple tasks from ID onwards
task-master update-subtask --id=<id> --prompt="notes"        # Add implementation notes to subtask

# Analysis & Planning (within current tag)
task-master analyze-complexity --research          # Analyze task complexity in current tag
task-master complexity-report                      # View complexity analysis for current tag
task-master expand --all --research               # Expand all eligible tasks in current tag

# Dependencies & Organization (within current tag)
task-master add-dependency --id=<id> --depends-on=<id>       # Add task dependency
task-master move --from=<id> --to=<id>                       # Reorganize task hierarchy
task-master validate-dependencies                            # Check for dependency issues
task-master generate                                         # Update task markdown files

Tagged Workflow Integration

⚠️ CRITICAL RULE: Never Work on Master Tag

NEVER work directly on the master tag. Always switch to a feature-specific tag before working with Task Master:

# ❌ BAD - Working on master tag
task-master use-tag master
task-master next                    # Don't do this!

# ✅ GOOD - Switch to feature tag first
task-master add-tag modal-panel-isolation --description="Modal panel isolation feature"
task-master use-tag modal-panel-isolation
task-master parse-prd .taskmaster/docs/prd-modal-panel-isolation.md
task-master next                    # Now this is correct!

Setting Up Tagged Contexts

1. Initialize Multiple Tag Contexts

# Create tag contexts for different features/areas
task-master add-tag user-auth --description="User authentication features"
task-master add-tag payments --description="Payment system implementation"
task-master add-tag mobile --description="Mobile app development"
task-master add-tag admin --description="Admin dashboard features"

2. Organize Tagged PRDs

Create PRDs for different contexts:

.taskmaster/docs/
  prd-master.md              # Main project PRD
  prd-user-authentication.md # Authentication feature PRD
  prd-payment-system.md      # Payment system PRD
  prd-mobile-app.md          # Mobile app PRD
  prd-admin-dashboard.md     # Admin features PRD

3. Parse PRDs into Tag Contexts

# Switch to authentication context and parse its PRD
task-master use-tag user-auth
task-master parse-prd .taskmaster/docs/prd-user-authentication.md

# Switch to payments context and parse its PRD
task-master use-tag payments
task-master parse-prd .taskmaster/docs/prd-payment-system.md

# Continue for each feature area...

Daily Tagged Development Workflow

1. Tag Context Management

# Check available tag contexts
task-master tags --show-metadata

# Switch to desired context (NEVER master for feature work!)
task-master use-tag user-auth

# Work within that context
task-master next                           # Find next task in current tag
task-master show <id>                     # Review task details in current tag

2. Cross-Tag Development

# Work on authentication, then switch to mobile
task-master use-tag user-auth
task-master list                          # See auth tasks
# ... work on auth tasks ...

task-master use-tag mobile
task-master list                          # See mobile tasks
# ... work on mobile tasks ...

3. Tag-Specific Implementation

# Within a tag context, all operations are isolated
task-master update-subtask --id=2.1 --prompt="implementation notes..."  # Updates task 2.1 in current tag only
task-master set-status --id=3 --status=done                            # Marks task 3 done in current tag only

Advanced Tagged Workflows

Branch-Based Tag Management

# Align tag contexts with git branches
git checkout -b feature/authentication
task-master add-tag --from-branch          # Creates tag from branch name

git checkout -b feature/payments
task-master add-tag --from-branch          # Creates another tag

Tag Copying and Templates

# Create new contexts from existing ones
task-master copy-tag user-auth admin-auth --description="Admin authentication"

# Copy tasks from current tag to new context
task-master add-tag testing --copy-from-current --description="QA testing tasks"

Cross-Tag Coordination

When coordinating work across tags:

  1. Plan Integration Points: Identify where different tag contexts need to interact
  2. Manual Coordination: Note cross-tag dependencies in task details
  3. Tag Switching: Use task-master use-tag to switch contexts as needed
  4. Documentation: Use task-master update-subtask to document cross-tag decisions

Tagged Task Structure & IDs

Tag-Specific Task IDs

  • Independent Numbering: Each tag maintains its own task sequence starting from 1
  • Main tasks: 1, 2, 3, etc. (within each tag)
  • Subtasks: 1.1, 1.2, 2.1, etc. (within each tag)
  • Sub-subtasks: 1.1.1, 1.1.2, etc. (within each tag)

Claude Code Best Practices with Tagged System

Tag Context Awareness

  • Always know your current tag context: task-master tags shows current context
  • Use /clear between different tag contexts to maintain focus
  • Use task-master show <id> to pull specific task context when needed
  • Remember: Task IDs are independent per tag (each tag has its own task 1, 2, 3...)

Tagged Implementation Strategy

  1. Context Setup: task-master use-tag <target-tag> - Switch to appropriate context
  2. Task Discovery: task-master show <id> - Understand requirements within tag
  3. Planning: task-master update-subtask --id=<id> --prompt="detailed plan" - Log plan in context
  4. Status Management: task-master set-status --id=<id> --status=in-progress - Start work in context
  5. Implementation: Implement code following logged plan
  6. Progress Logging: task-master update-subtask --id=<id> --prompt="progress notes" - Log within context
  7. Completion: task-master set-status --id=<id> --status=done - Complete within context

Cross-Tag Development Patterns

Feature Integration Workflow

# 1. Implement core feature in its tag
task-master use-tag user-auth
task-master show 2                           # Review auth API task
# ... implement auth APIs ...
task-master set-status --id=2 --status=done

# 2. Switch to consuming feature's tag
task-master use-tag mobile
task-master show 3                           # Review mobile integration task
task-master update-subtask --id=3.1 --prompt="Auth APIs completed in user-auth tag, ready for integration"
# ... implement integration ...

Cross-Tag Documentation

# Document cross-tag dependencies
task-master use-tag mobile
task-master update-subtask --id=3.2 --prompt="Depends on user-auth tag task 2 (OAuth setup) being completed"

# Document integration decisions
task-master update-subtask --id=3.3 --prompt="Using JWT tokens from auth service, implemented in user-auth tag"

Complex Tagged Workflows

Multi-Feature Migration

  1. Create Migration PRD: touch .taskmaster/docs/prd-migration.md
  2. Create Migration Tag: task-master add-tag migration --description="System migration tasks"
  3. Parse Migration: task-master use-tag migration && task-master parse-prd .taskmaster/docs/prd-migration.md
  4. Cross-Reference: Document which existing tags are affected in migration tasks
  5. Coordinate: Use task-master update-subtask to log progress across affected tags

Tag Lifecycle Management

# Development lifecycle
task-master add-tag feature-x --description="New feature development"    # Create
task-master use-tag feature-x                                           # Develop
task-master copy-tag feature-x testing-x --description="Feature testing" # Test
task-master delete-tag feature-x                                        # Cleanup

Git Integration with Tagged System

Tagged Task Master works excellently with git workflows:

# Align tags with branches
git checkout -b feature/user-authentication
task-master add-tag --from-branch

# Work within tag context
task-master use-tag feature-user-authentication
task-master next

# Commit with tag context
git commit -m "feat: implement OAuth setup (user-auth tag, task 1.2)"

# Create PR with tag context
gh pr create --title "Complete user-auth tag: OAuth integration" --body "Implements all user authentication tasks from user-auth tag context"

Parallel Development with Tagged Worktrees

# Create worktrees for different tag contexts
git worktree add ../project-auth feature/auth-system
git worktree add ../project-payment feature/payment-system
git worktree add ../project-mobile feature/mobile-app

# Run Claude Code in each worktree with different tag contexts
cd ../project-auth && claude       # Terminal 1: user-auth tag
cd ../project-payment && claude    # Terminal 2: payments tag
cd ../project-mobile && claude     # Terminal 3: mobile tag

Troubleshooting Tagged System

Tag Context Issues

# Check current tag context
task-master tags                              # Shows current tag (marked with *)

# Switch if needed
task-master use-tag <correct-tag>

# List tasks in current context
task-master list

Cross-Tag Dependencies

  • Note: Task dependencies only work within the same tag context
  • Workaround: Document cross-tag dependencies in task details using update-subtask
  • Coordination: Use clear naming and documentation for cross-tag integration points

Task File Sync Issues

# Regenerate task files for current tag
task-master generate

# Fix dependencies within current tag
task-master fix-dependencies

Important Tagged System Notes

Tag Context Isolation

  • Task IDs are independent per tag - each tag has its own sequence starting from 1
  • Dependencies only work within tags - cannot create dependencies across tags
  • Status and progress are tag-specific - marking task 1 done in tag A doesn't affect task 1 in tag B
  • Current tag context affects all operations - always verify you're in the correct tag

AI-Powered Operations (within current tag)

These commands work within the current tag context and may take up to a minute:

  • parse_prd / task-master parse-prd - Generates tasks in current tag
  • analyze_project_complexity / task-master analyze-complexity - Analyzes current tag's tasks
  • expand_task / task-master expand - Expands tasks in current tag
  • add_task / task-master add-task - Adds to current tag
  • update / task-master update - Updates tasks in current tag

File Management with Tagged System

  • Never manually edit tasks.json - contains all tag contexts, use commands instead
  • Current tag context is stored in .taskmaster/state.json
  • Task markdown files are generated with tag context information
  • Use task-master generate after any manual changes

Claude Code Session Management with Tags

  • Use /clear when switching between tag contexts to maintain focus
  • Start sessions by checking tag context: task-master tags
  • Use task-master use-tag <name> to switch contexts within session
  • Headless mode with tag context: claude -p "task-master use-tag auth && task-master next"

The tagged system ensures your task management scales with project complexity while maintaining clear organization and preventing conflicts across different feature areas or development contexts.
