🧊 IceCube Tasks

Tasks that survive session restarts.

Chat-based task lists die when context compacts. IceCube Tasks lives in files, tracked across sessions.

What This Skill Does

1. Task Persistence

• Tasks stored in state/tasks/ directory
• Survives context compaction
• Survives session restarts
• Survives agent crashes

2. Task Lifecycle

inbox → spec → in_progress → blocked → done
                    ↓
                 cancelled

3. Task Orchestration

• Break down large tasks into subtasks
• Assign to worker agents
• Track completion
• Handle handoffs

4. Blocker Management

• Track blockers explicitly
• Link to dependencies
• Auto-escalate stale blockers
• Resume when unblocked

Commands

Create Task

# Write to state/tasks/task_ledger/TASK-XXX.yaml
id: TASK-XXX
title: "Task title"
status: inbox
created_at: <now>

Start Task

# Update task file
status: in_progress
updated_at: <now>
assigned_to: <agent>

# Update current_dispatch.yaml
focused_task: TASK-XXX

Block Task

# Update task file
status: blocked
blocked_reason: "Why blocked"
blocked_until: "When it might be resolved"
updated_at: <now>

# Update unclosed_work.yaml
- Add blocker note

Complete Task

# Update task file
status: done
completed_at: <now>

# Move to completed/
# Update current_dispatch.yaml
focused_task: null

Orchestration Patterns

Pattern 1: Sequential

TASK-001 → TASK-002 → TASK-003

Each task blocks the next.

Pattern 2: Parallel

TASK-001 ─┬→ TASK-003
TASK-002 ─┘

TASK-003 depends on both.

Pattern 3: Delegated

main_agent → worker_agent (TASK-001)
          → worker_agent (TASK-002)

Subagents execute parallel tasks.

Pattern 4: User-Blocked

TASK-001 → [waiting for user] → TASK-001 continues

Agent can't proceed without user input.

Anti-Patterns

❌ Don't:

• Create tasks without writing to files
• Update status in chat only
• Forget about blocked tasks
• Leave tasks in limbo

✅ Do:

• Write every task to a file
• Update status immediately
• Check blockers regularly
• Close tasks explicitly

Integration with IceCube Suite

icecube-heartbeat: Checks for stale tasks during heartbeat icecube-evolution: Failed tasks feed improvement queue icecube-memory: Task context loaded on startup

Task Recovery

If agent crashes or restarts:

1. Read state/tasks/current_dispatch.yaml
2. Find focused_task
3. Read task file from task_ledger/
4. Resume from last completed step

Metrics

Track in state/tasks/metrics.yaml:

total_created: 47
total_completed: 42
total_cancelled: 3
currently_open: 5
avg_completion_time: 2.3h
blocker_rate: 15%
