Task Management

Task Management Skill

> Purpose: Track, manage, and validate feature implementations with atomic task breakdowns, dependency resolution, and progress monitoring.

---

What I Do

I provide a command-line interface for managing task breakdowns created by the TaskManager subagent. I help you:

• Track progress - See status of all features and their subtasks
• Find next tasks - Show eligible tasks (dependencies satisfied)
• Identify blocked tasks - See what's blocked and why
• Manage completion - Mark subtasks as complete with summaries
• Validate integrity - Check JSON files and dependency trees

---

How to Use Me

Quick Start

# Show all task statuses
bash .opencode/skills/task-management/router.sh status

# Show next eligible tasks
bash .opencode/skills/task-management/router.sh next

# Show blocked tasks
bash .opencode/skills/task-management/router.sh blocked

# Mark a task complete
bash .opencode/skills/task-management/router.sh complete   "summary"

# Validate all tasks
bash .opencode/skills/task-management/router.sh validate

Command Reference

| Command | Description | |---------|-------------| | status [feature] | Show task status summary for all features or specific one | | next [feature] | Show next eligible tasks (dependencies satisfied) | | parallel [feature] | Show parallelizable tasks ready to run | | deps | Show dependency tree for a specific subtask | | blocked [feature] | Show blocked tasks and why | | complete "summary" | Mark subtask complete with summary | | validate [feature] | Validate JSON files and dependencies | | help | Show help message |

Examples

Check Overall Progress

$ bash .opencode/skills/task-management/router.sh status

[my-feature] My Feature Implementation
  Status: active | Progress: 45% (5/11)
  Pending: 3 | In Progress: 2 | Completed: 5 | Blocked: 1

Find What's Next

$ bash .opencode/skills/task-management/router.sh next

=== Ready Tasks (deps satisfied) ===

[my-feature]
  06 - Implement API endpoint [sequential]
  08 - Write unit tests [parallel]

Mark Complete

$ bash .opencode/skills/task-management/router.sh complete my-feature 05 "Implemented authentication module"

✓ Marked my-feature/05 as completed
  Summary: Implemented authentication module
  Progress: 6/11

Check Dependencies

$ bash .opencode/skills/task-management/router.sh deps my-feature 07

=== Dependency Tree: my-feature/07 ===

07 - Write integration tests [pending]
  ├── ✓ 05 - Implement authentication module [completed]
  └── ○ 06 - Implement API endpoint [in_progress]

Validate Everything

$ bash .opencode/skills/task-management/router.sh validate

=== Validation Results ===

[my-feature]
  ✓ All checks passed

Task File Structure

Tasks are stored in .tmp/tasks/ at the project root:

.tmp/tasks/
├── {feature-slug}/
│   ├── task.json                     # Feature-level metadata
│   ├── subtask_01.json               # Subtask definitions
│   ├── subtask_02.json
│   └── ...
└── completed/
    └── {feature-slug}/               # Completed tasks

  "id": "my-feature",
  "name": "My Feature",
  "status": "active",
  "objective": "Implement X",

Integration with TaskManager

The TaskManager subagent creates task files using this format. When you delegate to TaskManager:

task(
  subagent_type="TaskManager",
  description="Implement feature X",
  prompt="Break down this feature into atomic subtasks..."
)

TaskManager creates:

1. .tmp/tasks/{feature}/task.json - Feature metadata
2. .tmp/tasks/{feature}/subtask_XX.json - Individual subtasks

You can then use this skill to track and manage progress.

Key Concepts

1. Dependency Resolution

Subtasks can depend on other subtasks. A task is "ready" only when all its dependencies are complete.

2. Parallel Execution

Set parallel: true to indicate a subtask can run alongside other parallel tasks with satisfied dependencies.

3. Status Tracking

• pending - Not started, waiting for dependencies
• in_progress - Currently being worked on
• completed - Finished with summary
• blocked - Explicitly blocked (not waiting for deps)

4. Exit Criteria

Each feature has exit_criteria that must be met before marking the feature complete.

5. Validation Rules

The validate command performs comprehensive checks on task files:

Task-Level Validation:

• ✅ task.json file exists for the feature
• ✅ Task ID matches feature slug
• ✅ Subtask count in task.json matches actual subtask files
• ✅ All required fields are present

Subtask-Level Validation:

• ✅ All subtask IDs start with feature name (e.g., "my-feature-01")
• ✅ Sequence numbers are unique and properly formatted (01, 02, etc.)
• ✅ All dependencies reference existing subtasks
• ✅ No circular dependencies exist
• ✅ Each subtask has acceptance criteria defined
• ✅ Each subtask has deliverables specified
• ✅ Status values are valid (pending, in_progress, completed, blocked)

Dependency Validation:

• ✅ All depends_on references point to existing subtasks
• ✅ No task depends on itself
• ✅ No circular dependency chains
• ✅ Dependency graph is acyclic

Run validate regularly to catch issues early:

bash .opencode/skills/task-management/router.sh validate my-feature

6. Context and Reference Files

• context_files - Standards, conventions, and guidelines to follow
• reference_files - Existing project files to look at or build upon

Workflow Integration

With TaskManager Subagent

1. TaskManager creates tasks → Generates .tmp/tasks/{feature}/ structure
2. You use this skill to track → Monitor progress with status, next, blocked
3. You mark tasks complete → Use complete command with summaries
4. Skill validates integrity → Use validate to check consistency

With Other Subagents

Working agents (CoderAgent, TestEngineer, etc.) execute subtasks and report completion. Use this skill to:

• Find next available tasks with next
• Check what's blocking progress with blocked
• Validate task definitions with validate

---

Common Workflows

Starting a New Feature

# 1. TaskManager creates the task structure
task(subagent_type="TaskManager", description="Implement feature X", ...)

# 2. Check what's ready
bash .opencode/skills/task-management/router.sh next

# 3. Delegate first task to working agent
task(subagent_type="CoderAgent", description="Implement subtask 01", ...)

Tracking Progress

# Check overall status
bash .opencode/skills/task-management/router.sh status my-feature

# See what's next
bash .opencode/skills/task-management/router.sh next my-feature

# Check what's blocked
bash .opencode/skills/task-management/router.sh blocked my-feature

Completing Tasks

# After working agent finishes
bash .opencode/skills/task-management/router.sh complete my-feature 05 "Implemented auth module with JWT support"

# Check progress
bash .opencode/skills/task-management/router.sh status my-feature

# Find next task
bash .opencode/skills/task-management/router.sh next my-feature

Validating Everything

# Validate all tasks
bash .opencode/skills/task-management/router.sh validate

# Validate specific feature
bash .opencode/skills/task-management/router.sh validate my-feature

---

Tips & Best Practices

1. Use Meaningful Summaries

When marking tasks complete, provide clear summaries:

# Good
complete my-feature 05 "Implemented JWT authentication with refresh tokens and error handling"

# Avoid
complete my-feature 05 "Done"

2. Check Dependencies Before Starting

# See what a task depends on
bash .opencode/skills/task-management/router.sh deps my-feature 07

3. Identify Parallelizable Work

# Find tasks that can run in parallel
bash .opencode/skills/task-management/router.sh parallel my-feature

4. Regular Validation

# Validate regularly to catch issues early
bash .opencode/skills/task-management/router.sh validate

Troubleshooting

"task-cli.ts not found"

Make sure you're running from the project root or the router.sh can find it.

"No tasks found"

Run status to see if any tasks have been created yet. Use TaskManager to create tasks first.

"Dependency not satisfied"

Check the dependency tree with deps to see what's blocking the task.

"Validation failed"

Run validate to see specific issues, then check the JSON files in .tmp/tasks/.
