issue:queue

Queue formation command using issue-queue-agent that analyzes bound solutions, resolves inter-solution conflicts, and creates an ordered execution queue.

Description

The issue:queue command creates execution queues from planned issues with bound solutions. It performs solution-level conflict analysis, builds dependency DAGs, calculates semantic priority, and assigns execution groups (parallel/sequential).

Key Features

  • Solution-level granularity: Queue items are complete solutions, not individual tasks
  • Conflict resolution: Automatic detection and user clarification for high-severity conflicts
  • Multi-queue support: Create parallel queues for distributed execution
  • Semantic priority: Intelligent ordering based on issue priority and task complexity
  • DAG-based grouping: Parallel (P*) and Sequential (S*) execution groups
  • Queue history: Track all queues with active queue management

Usage

# Form new queue from all bound solutions
/issue:queue

# Form 3 parallel queues (solutions distributed)
/issue:queue --queues 3

# Form queue for specific issue only
/issue:queue --issue GH-123

# Append to active queue
/issue:queue --append GH-124

# List all queues
/issue:queue --list

# Switch active queue
/issue:queue --switch QUE-xxx

# Archive completed queue
/issue:queue --archive

Arguments

ArgumentRequiredDescription
--queues <n>NoNumber of parallel queues (default: 1)
--issue <id>NoForm queue for specific issue only
--append <id>NoAppend issue to active queue
--forceNoSkip active queue check, always create new
-y, --yesNoAuto-confirm, use recommended resolutions

CLI Subcommands

ccw issue queue list                  # List all queues with status
ccw issue queue add <issue-id> # Add issue to queue
ccw issue queue add <issue-id> -f # Force add to new queue
ccw issue queue merge <src> --queue <target> # Merge queues
ccw issue queue switch <queue-id> # Switch active queue
ccw issue queue archive # Archive current queue
ccw issue queue delete <queue-id> # Delete queue from history

Examples

Create Single Queue

/issue:queue
# Output:
# Loading 5 bound solutions...
# Generating queue: QUE-20251227-143000
# Analyzing conflicts...
# ✓ Queue created: 5 solutions, 3 execution groups
# - P1: S-1, S-2 (parallel)
# - S1: S-3 (sequential)
# - P2: S-4, S-5 (parallel)
# Next: /issue:execute --queue QUE-20251227-143000

Create Multiple Parallel Queues

/issue:queue --queues 3
# Distributes solutions to minimize cross-queue conflicts
# Creates: QUE-20251227-143000-1, QUE-20251227-143000-2, QUE-20251227-143000-3
# All linked via queue_group: QGR-20251227-143000

Append to Existing Queue

/issue:queue --append GH-124
# Checks active queue exists
# Adds new solution to end of active queue
# Recalculates execution groups

Issue Lifecycle Flow

Execution Groups

Parallel Groups (P*)

Solutions with NO file conflicts can execute simultaneously:

P1: S-1, S-2, S-3  → 3 executors work in parallel

Sequential Groups (S*)

Solutions with shared dependencies must execute in order:

S1: S-4 → S-5 → S-6  → Execute one after another

Mixed Execution

P1: S-1, S-2 (parallel)

S1: S-3 (sequential, waits for P1)

P2: S-4, S-5 (parallel, waits for S1)

Conflict Types

1. File Conflicts

Solutions modify the same file:

{
"conflict_id": "CFT-1",
"type": "file",
"severity": "high",
"solutions": ["S-1", "S-2"],
"files": ["src/auth/login.ts"],
"resolution": "sequential"
}

Resolution: S-1 before S-2 in sequential group

2. API Conflicts

Solutions change shared interfaces:

{
"conflict_id": "CFT-2",
"type": "api",
"severity": "high",
"solutions": ["S-3", "S-4"],
"interfaces": ["AuthService.login()"],
"resolution": "sequential"
}

Resolution: User clarifies which approach to use

3. Data Conflicts

Solutions modify same database schema:

{
"conflict_id": "CFT-3",
"type": "data",
"severity": "medium",
"solutions": ["S-5", "S-6"],
"tables": ["users"],
"resolution": "sequential"
}

Resolution: S-5 before S-6

4. Dependency Conflicts

Solutions require incompatible versions:

{
"conflict_id": "CFT-4",
"type": "dependency",
"severity": "high",
"solutions": ["S-7", "S-8"],
"packages": ["redis@4.x vs 5.x"],
"resolution": "clarification"
}

Resolution: User selects version or defers one solution

5. Architecture Conflicts

Solutions have opposing architectural approaches:

{
"conflict_id": "CFT-5",
"type": "architecture",
"severity": "medium",
"solutions": ["S-9", "S-10"],
"approaches": ["monolithic", "microservice"],
"resolution": "clarification"
}

Resolution: User selects approach or separates concerns

Clarification Flow

When high-severity conflicts exist without clear resolution:

# Interactive prompt
[CFT-5] File conflict: src/auth/login.ts modified by both S-1 and S-2
Options:
[1] Sequential: Execute S-1 first, then S-2
[2] Sequential: Execute S-2 first, then S-1
[3] Merge: Combine changes into single solution
[4] Defer: Remove one solution from queue

User selects: [1]

# Agent resumes with resolution
# Updates queue with sequential ordering: S1: [S-1, S-2]
  • issue:plan - Plan solutions before queuing
  • issue:execute - Execute queued solutions
  • issue:new - Create issues to plan and queue
  • ccw issue queue dag - View dependency graph
  • ccw issue next - Get next item from queue

Best Practices

  1. Plan before queue: Ensure all issues have bound solutions
  2. Review conflicts: Check conflict report before execution
  3. Use parallel queues: For large projects, distribute work
  4. Archive completed: Keep queue history for reference
  5. Check unplanned: Review planned but unqueued issues
  6. Validate DAG: Ensure no circular dependencies
