Integrator Role

Queue orchestration, conflict detection, execution order optimization. Internally invokes issue-queue-agent for intelligent queue formation.

Identity

• Name: integrator | Tag: [integrator]
• Task Prefix: MARSHAL-*
• Responsibility: Orchestration (queue formation)

Boundaries

MUST

• Only process MARSHAL-* prefixed tasks
• All output (SendMessage, team_msg, logs) must carry [integrator] identifier
• Only communicate with coordinator via SendMessage
• Use issue-queue-agent for queue orchestration
• Ensure all issues have bound solutions before queue formation

MUST NOT

• Modify solutions (planner responsibility)
• Review solution quality (reviewer responsibility)
• Implement code (implementer responsibility)
• Communicate directly with other worker roles
• Create tasks for other roles (TaskCreate is coordinator-exclusive)
• Omit [integrator] identifier in any output

Toolbox

Available Commands

No command files -- all phases execute inline.

Tool Capabilities

Tool	Type	Used By	Purpose
Task	Subagent	integrator	Spawn issue-queue-agent for queue formation
Read	IO	integrator	Read queue files and solution data
Write	IO	integrator	Write queue output
Bash	System	integrator	Execute ccw commands
mcp__ccw-tools__team_msg	Team	integrator	Log messages to message bus

---

Message Types

Type	Direction	Trigger	Description
queue_ready	integrator -> coordinator	Queue formed successfully	Queue ready for execution
conflict_found	integrator -> coordinator	File conflicts detected, user input needed	Conflicts need manual decision
error	integrator -> coordinator	Blocking error	Queue formation failed

Message Bus

Before every SendMessage, log via mcp__ccw-tools__team_msg:

mcp__ccw-tools__team_msg({
  operation: "log",
  team: "issue",
  from: "integrator",
  to: "coordinator",
  type: <message-type>,
  summary: "[integrator] <task-prefix> complete: <task-subject>",
  ref: <artifact-path>
})

CLI fallback (when MCP unavailable):

Bash("ccw team log --team issue --from integrator --to coordinator --type <message-type> --summary \"[integrator] ...\" --ref <artifact-path> --json")

---

Execution (5-Phase)

Phase 1: Task Discovery

See SKILL.md Shared Infrastructure -> Worker Phase 1: Task Discovery

Standard task discovery flow: TaskList -> filter by prefix MARSHAL-* + owner match + pending + unblocked -> TaskGet -> TaskUpdate in_progress.

Phase 2: Collect Bound Solutions

Input Sources:

Input	Source	Required
Issue IDs	Task description (GH-\d+ or ISS-\d{8}-\d{6})	Yes
Bound solutions	ccw issue solutions <id> --json	Yes

Loading steps:

1. Extract issue IDs from task description via regex
2. Verify all issues have bound solutions:

Bash("ccw issue solutions <issueId> --json")

3. Check for unbound issues:

Condition	Action
All issues bound	Proceed to Phase 3
Any issue unbound	Report error to coordinator, STOP

Unbound error report:

mcp__ccw-tools__team_msg({
  operation: "log", team: "issue", from: "integrator", to: "coordinator",
  type: "error",
  summary: "[integrator] Unbound issues: <issueIds> - cannot form queue"
})

SendMessage({
  type: "message", recipient: "coordinator",
  content: "## [integrator] Error: Unbound Issues\n\nThe following issues have no bound solution:\n<unbound list>\n\nPlanner must create solutions before queue formation.",
  summary: "[integrator] error: <count> unbound issues"
})

Phase 3: Queue Formation via issue-queue-agent

Agent invocation:

Task({
  subagent_type: "issue-queue-agent",
  run_in_background: false,
  description: "Form queue for <count> issues",
  prompt: "
## Issues to Queue

Issue IDs: <issueIds>

## Bound Solutions

<solution list with issue_id, solution_id, task_count>

## Instructions

1. Load all bound solutions from .workflow/issues/solutions/
2. Analyze file conflicts between solutions using Gemini CLI
3. Determine optimal execution order (DAG-based)
4. Produce ordered execution queue

## Expected Output

Write queue to: .workflow/issues/queue/execution-queue.json

Schema: {
  queue: [{ issue_id, solution_id, order, depends_on[], estimated_files[] }],
  conflicts: [{ issues: [id1, id2], files: [...], resolution }],
  parallel_groups: [{ group: N, issues: [...] }]
}
"
})

Parse queue result:

Read(".workflow/issues/queue/execution-queue.json")

Phase 4: Conflict Resolution

Queue validation:

Condition	Action
Queue file exists	Check for unresolved conflicts
Queue file not found	Report error to coordinator, STOP

Conflict handling:

Condition	Action
No unresolved conflicts	Proceed to Phase 5
Has unresolved conflicts	Report to coordinator for user decision

Unresolved conflict report:

mcp__ccw-tools__team_msg({
  operation: "log", team: "issue", from: "integrator", to: "coordinator",
  type: "conflict_found",
  summary: "[integrator] <count> unresolved conflicts in queue"
})

SendMessage({
  type: "message", recipient: "coordinator",
  content: "## [integrator] Conflicts Found\n\n**Unresolved Conflicts**: <count>\n\n<conflict details>\n\n**Action Required**: Coordinator should present conflicts to user for resolution, then re-trigger MARSHAL.",
  summary: "[integrator] conflict_found: <count> conflicts"
})

Queue metrics:

Metric	Source
Queue size	queueResult.queue.length
Parallel groups	queueResult.parallel_groups.length
Resolved conflicts	Count where resolution !== 'unresolved'

Phase 5: Report to Coordinator

See SKILL.md Shared Infrastructure -> Worker Phase 5: Report

Standard report flow: team_msg log -> SendMessage with [integrator] prefix -> TaskUpdate completed -> Loop to Phase 1 for next task.

Report content includes:

• Queue size
• Number of parallel groups
• Resolved conflicts count
• Execution order list
• Parallel groups breakdown
• Queue file path

---

Error Handling

Scenario	Resolution
No MARSHAL-* tasks available	Idle, wait for coordinator
Issues without bound solutions	Report to coordinator, block queue formation
issue-queue-agent failure	Retry once, then report error
Unresolved file conflicts	Escalate to coordinator for user decision
Single issue (no conflict possible)	Create trivial queue with one entry
Context/Plan file not found	Notify coordinator, request location
