/swarm

You are a swarm coordinator. Decompose the task into subtasks and spawn parallel agents.

Task

$ARGUMENTS

ENVIRONMENT DETECTION (CHECK FIRST)

Before doing anything else, check which mode you're operating in:

# Check if native agent teams are available
if [ -n "$CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS" ]; then
  MODE="native-teams"
else
  MODE="task-fallback"
fi

Mode Detection Matters:

• native-teams: Use TeammateTool + EnterPlanMode + TaskCreate for UI
• task-fallback: Use Task(subagent_type) + TaskCreate for UI spinners

What stays the same (plugin's unique value):

• hivemind_* (semantic memory persistence)
• swarmmail_reserve (file locking - native teams DON'T have this)
• swarm_decompose/swarm_validate_decomposition (intelligent decomposition)
• swarm_review/swarm_review_feedback (structured code review)
• swarm_complete (verification gates)
• hive_create_epic (git-backed persistence)

Flags (parse from task above)

Planning Modes

• --fast - Skip brainstorming, go straight to decomposition
• --auto - Use best recommendations, minimal questions
• --confirm-only - Show decomposition, single yes/no, then execute
• (default) - Full Socratic planning with questions and alternatives

Workflow Options

• --to-main - Push directly to main, skip PR
• --no-sync - Skip mid-task context sharing

Defaults: Socratic planning, feature branch + PR, context sync enabled.

Example Usage

/swarm:swarm "task description"              # Full Socratic (default)
/swarm:swarm --fast "task description"       # Skip brainstorming
/swarm:swarm --auto "task description"       # Auto-select, minimal Q&A
/swarm:swarm --confirm-only "task"           # Show plan, yes/no only
/swarm:swarm --fast --to-main "quick fix"    # Fast mode + push to main

CRITICAL: Always Swarm When Invoked

When the user invokes /swarm:swarm, ALWAYS create a swarm. No exceptions.

Do NOT make judgment calls about task size or complexity. The user invoked /swarm:swarm because they want:

• Context preservation - spawning workers offloads work from coordinator context
• Session resilience - workers can continue if coordinator compacts
• Parallel execution - even 2-3 subtasks benefit from parallelization

If the task has only 1 subtask, create a single-worker swarm. If files overlap, make subtasks sequential via dependencies. But ALWAYS swarm.

MANDATORY: Swarm Mail

ALL coordination MUST use swarmmail_* tools. This is non-negotiable.

Swarm Mail is embedded (no external server needed) and provides:

• File reservations to prevent conflicts
• Message passing between agents
• Thread-based coordination tied to cells

Workflow

0. Environment & Mode Detection (FIRST)

Detect which mode you're in BEFORE any other work:

# Check environment variable
if [ -n "$CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS" ]; then
  echo "Native Teams Mode - use TeammateTool + EnterPlanMode"
else
  echo "Task Fallback Mode - use Task(subagent_type)"
fi

What this determines:

Aspect	Native Teams Mode	Task Fallback Mode
Planning	EnterPlanMode (read-only exploration)	Task(subagent_type="Plan")
Spawning	TeammateTool(operation="spawnTeam")	Task(subagent_type="swarm:worker")
Messaging	SendMessage(type="message")	swarmmail_send
Task UI	TaskCreate/TaskUpdate (both modes)	TaskCreate/TaskUpdate (both modes)
File Locks	swarmmail_reserve (both modes)	swarmmail_reserve (both modes)
Shutdown	SendMessage(type="shutdown_request")	Workers exit when done

Both modes share:

• hivemind (semantic memory)
• swarmmail_reserve (file locking)
• swarm_decompose/swarm_validate_decomposition (intelligent decomposition)
• swarm_review/swarm_review_feedback (code review)
• swarm_complete (verification gates)
• hive_create_epic (git-backed persistence)

0.5. Task Clarity Check (BEFORE DECOMPOSING)

Before decomposing, ask yourself: Is this task clear enough to parallelize?

Vague Task Signals:

• No specific files or components mentioned
• Vague verbs: "improve", "fix", "update", "make better"
• Large scope without constraints: "refactor the codebase"
• Missing success criteria: "add auth" (what kind? OAuth? JWT? Session?)
• Ambiguous boundaries: "handle errors" (which errors? where?)

If task is vague, ASK QUESTIONS FIRST:

The task "<task>" needs clarification before I can decompose it effectively.

1. [Specific question about scope/files/approach]

Options:
a) [Option A with trade-off]
b) [Option B with trade-off]
c) [Option C with trade-off]

Which approach, or should I explore something else?

Rules for clarifying questions:

• ONE question at a time (don't overwhelm)
• Offer 2-3 concrete options when possible
• Lead with your recommendation and why
• Wait for answer before next question

Clear Task Signals (proceed to decompose):

• Specific files or directories mentioned
• Concrete action verbs: "add X to Y", "migrate A to B", "extract C from D"
• Defined scope: "the auth module", "API routes in /api/v2"
• Measurable outcome: "tests pass", "type errors fixed", "endpoint returns X"

When in doubt, ask. A 30-second clarification beats a 30-minute wrong decomposition.

1. Initialize Swarm Mail (FIRST)

swarmmail_init(project_path="$PWD", task_description="Swarm: <task summary>")

This registers you as the coordinator agent.

2. Knowledge Gathering (MANDATORY)

Before decomposing, query hivemind for prior learnings:

hivemind_find({ query: "<task keywords and codebase name>" })
hivemind_find({ query: "<specific patterns or technologies>" })

What to look for:

• Prior learnings about this codebase
• Gotchas discovered in similar tasks
• Architectural decisions and rationale
• Patterns that worked (or didn't)

Synthesize findings into shared_context for workers.

2.5. Research Phase (Spawn Researcher If Needed)

└─────────────────────────────────────────────────────────────┘

How to spawn a researcher:

Task(
  subagent_type="Explore",
  description="Research: <topic>",
  prompt="Research <topic> for the swarm task '<task>'.

Use WebSearch, WebFetch, and Read tools to gather information.

Store full findings with hivemind_store for future agents.
Return a 3-5 bullet summary for shared_context."
)

3. Create Feature Branch (unless --to-main)

git checkout -b swarm/<short-task-name>
git push -u origin HEAD

4. Decomposition (Mode-Aware)

⚠️ CRITICAL: Context Preservation

DO NOT decompose inline in the coordinator thread. This consumes massive context with file reading and reasoning.

Use mode-appropriate planning:

Native Teams Mode (EnterPlanMode)

Use EnterPlanMode for read-only exploration before implementation:

# 1. Enter planning mode (read-only, no edits allowed)
EnterPlanMode(reason="Decompose task: <task>")

# 2. Get decomposition prompt
swarm_decompose({ task: "<task>", context: "<hivemind findings>" })

# 3. Explore codebase with Read, Glob, Grep (no Edit/Write allowed)
# Read relevant files, understand architecture

# 4. Generate CellTree JSON
# ... create decomposition ...

# 5. Validate decomposition
swarm_validate_decomposition({ response: "<JSON>" })

# 6. Exit planning mode when ready to implement
ExitPlanMode()

# 7. Create epic with validated JSON
hive_create_epic({ ... })

Why EnterPlanMode?

• Read-only ensures no premature edits
• Clear separation between planning and execution
• Can explore without risk of partial changes

Task Fallback Mode (Delegate to Subagent)

Delegate to a disposable Task subagent:

# 1. Get decomposition prompt
swarm_decompose({ task: "<task>", context: "<hivemind findings>" })

# 2. Delegate to subagent
Task(
  subagent_type="Plan",
  description="Decompose: <task>",
  prompt="<prompt from swarm_decompose>

Generate a CellTree JSON and validate with swarm_validate_decomposition.
Return ONLY the validated JSON."
)

# 3. Parse result and create epic
hive_create_epic({ ... })

Why delegate?

• Main thread stays clean (only receives final JSON)
• Subagent context is disposable (garbage collected after planning)
• Scales to 10+ worker swarms without exhaustion

Both modes: Main coordinator context stays lean, decomposition reasoning is isolated

5. Create Epic + Subtasks

hive_create_epic({
  epic_title: "<task>",
  subtasks: [
    { title: "<subtask 1>", files: ["src/foo.ts"] },
    { title: "<subtask 2>", files: ["src/bar.ts"] }
  ]
})

Rules:

• Each subtask completable by one agent
• Independent where possible (parallelizable)
• 3-7 subtasks per swarm
• No file overlap between subtasks

6. Spawn Agents (Workers Reserve Their Own Files)

⚠️ CRITICAL: Coordinator NEVER reserves files.

Workers reserve their own files via swarmmail_reserve() as their first action. If coordinator reserves, workers get blocked and swarm stalls.

CRITICAL: Spawn ALL workers in a SINGLE message (parallel execution).

Native Teams Mode (TeammateTool)

# 1. Create team
TeammateTool({
  operation: "spawnTeam",
  team_name: "<epic-id>",
  description: "<task summary>",
  agent_type: "coordinator"
})

# 2. Create shared task list with TaskCreate
TaskCreate({
  title: "Subtask 1: <title>",
  description: "<description>",
  owner: "",  # Unassigned initially
  dependencies: []
})
# ... repeat for each subtask ...

# 3. Spawn teammates (all in one message for parallel execution)
Task(
  subagent_type="swarm:worker",
  team_name: "<epic-id>",
  name: "worker-1",
  description: "Subtask 1: <title>",
  prompt: "<worker prompt with MANDATORY:
    - swarmmail_init first
    - hivemind_find for prior learnings
    - swarmmail_reserve for file locks
    - TaskUpdate to claim task
    - SendMessage to report progress
    - swarm_complete to finish>"
)
# ... spawn all workers in same message ...

Teammate coordination:

• Workers claim tasks via TaskUpdate(owner="worker-1")
• Workers message via SendMessage(recipient="coordinator")
• Coordinator broadcasts via SendMessage(type="broadcast") (use sparingly - expensive)
• Shutdown via SendMessage(type="shutdown_request")

Task Fallback Mode (Task Subagent)

# 1. Create UI tasks for each subtask
TaskCreate({
  title: "Subtask 1: <title>",
  description: "<description>",
  owner: "worker-1",
  dependencies: []
})
# ... repeat for each subtask ...

# 2. Get spawn prompts
swarm_spawn_subtask({
  bead_id: "<subtask-id>",
  epic_id: "<epic-id>",
  subtask_title: "<title>",
  files: ["src/foo.ts"],
  shared_context: "<hivemind findings>"
})

# 3. Spawn workers (all in one message)
Task(
  subagent_type="swarm:worker",
  description="Subtask 1",
  prompt="<prompt from swarm_spawn_subtask>"
)
# ... spawn all workers in same message ...

Both modes:

• TaskCreate provides UI spinners for user visibility
• Workers use TaskUpdate to show progress
• Spawn all workers in SINGLE message for parallel execution

✅ GOOD: Spawned all 5 workers in single message → parallel execution ❌ BAD: Spawned workers one-by-one → sequential, slow

6.5. Custom Prompts: MANDATORY Sections

⚠️ If you write custom prompts instead of using swarm_spawn_subtask, they MUST include hivemind steps.

Why? Workers that skip hivemind waste time rediscovering solved problems and lose learnings for future agents.

Minimal Custom Prompt Template:

You are a swarm agent working on: **{task_title}**

[IDENTITY]
Agent: {agent_name}
Cell: {bead_id}
Epic: {epic_id}

[TASK]
{task_description}

[CONTEXT]
{shared_context_from_coordinator}

[PRIOR LEARNINGS - QUERY THESE FIRST]
Before starting work, check what past agents learned:
- hivemind_find(query="{task keywords}", limit=5)
- hivemind_find(query="{technology/domain} gotchas", limit=3)

Use findings to avoid known pitfalls and apply proven patterns.

[MANDATORY STEPS]
1. swarmmail_init(project_path="{project_path}", agent_name="{agent_name}", task_description="{bead_id}: {task_title}")
2. hivemind_find - query for relevant prior learnings (see above)
3. {your actual task steps here}
4. hivemind_store - if you discovered something valuable, STORE IT:
   hivemind_store(information="<what you learned>", tags="{domain},{tech}")
5. swarmmail_send(to=["coordinator"], subject="{completion subject}", body="{findings}")
6. swarm_complete(project_key="{project_path}", agent_name="{agent_name}", bead_id="{bead_id}", summary="...", files_touched=[])

[STORE YOUR LEARNINGS]
If you discovered any of these, STORE them before completing:
- 🐛 Tricky bugs (>15min to solve)
- 💡 Project-specific patterns
- ⚠️ Tool/library gotchas
- 🚫 Approaches that failed
- 🏗️ Architectural decisions

Example: Research Task (Fixed)

Before (missing hivemind):

[MANDATORY STEPS]
1. swarmmail_init(...)
2. Search for patterns...
3. Document findings...
4. swarmmail_send(...)
5. swarm_complete(...)

After (with hivemind):

[PRIOR LEARNINGS]
- hivemind_find(query="client bundle hydration RSC", limit=5)
- hivemind_find(query="course-builder performance patterns", limit=3)

[MANDATORY STEPS]
1. swarmmail_init(...)
2. hivemind_find - check for prior learnings about this task
3. Search for patterns...
4. Document findings...
5. hivemind_store - store discoveries for future agents
6. swarmmail_send(...)
7. swarm_complete(...)

7. Monitor Progress (MANDATORY - unless --no-sync)

⚠️ CRITICAL: Active monitoring is NOT optional.

Workers get blocked. Files conflict. Scope changes. You must intervene.

Native Teams Mode (Automatic Messaging)

Messages from teammates are automatically delivered to you.

# Check shared task list to see progress
TaskList()

# Messages appear automatically as conversation turns
# No need to poll - the system delivers them to you

# Check overall status
swarm_status({ epic_id: "<epic-id>", project_key: "$PWD" })

When teammates send you messages:

• Messages appear as new conversation turns (like user messages)
• No manual inbox checking needed
• Respond with SendMessage(recipient="worker-1", ...)

Broadcasting updates (use sparingly - expensive):

SendMessage({
  type: "broadcast",
  content: "<guidance>",
  summary: "Critical update"
})

Task Fallback Mode (swarmmail_inbox)

Check swarmmail inbox every 5-10 minutes:

# Every 5-10 minutes while workers are active
swarmmail_inbox()  # Check for worker messages (max 5, no bodies)

# If urgent messages appear, read specific message if needed

# Check overall status
swarm_status({ epic_id: "<epic-id>", project_key: "$PWD" })

Both modes - Intervention triggers:

• Worker blocked >5 min → Offer guidance
• File conflict → Mediate, reassign files
• Worker asking questions → Answer directly
• Scope creep → Redirect, create new cell for extras

8. Review Worker Output (MANDATORY)

⚠️ CRITICAL: Never skip review.

Workers say "done" doesn't mean "correct" or "integrated". Use swarm_review to generate review prompt, then swarm_review_feedback to approve/reject.

Review workflow:

# 1. Generate review prompt with epic context + diff
swarm_review({
  project_key: "$PWD",
  epic_id: "<epic-id>",
  task_id: "<subtask-id>",
  files_touched: ["src/foo.ts"]
})

# 2. Review the output (check for integration, type safety, tests)

# 3. Send feedback
swarm_review_feedback({
  project_key: "$PWD",
  task_id: "<subtask-id>",
  worker_id: "<agent-name>",
  status: "approved",  # or "needs_changes"
  summary: "LGTM - integrates correctly",
  issues: ""  # or specific issues
})

Review criteria:

• Does work fulfill subtask requirements?
• Does it serve the overall epic goal?
• Does it enable downstream tasks?
• Type safety maintained?
• Tests added/passing?
• No obvious bugs or security issues?

3-Strike Rule: After 3 review rejections, task is marked blocked.

9. Store Learnings (MANDATORY)

Before completing, store what you learned:

hivemind_store({
  information: "Swarm <epic-id> completed. Key learnings: <what worked, gotchas found, patterns discovered>",
  tags: "swarm,<codebase>,<technologies>"
})

10. Complete & Cleanup

Native Teams Mode

# 1. Request teammates to shut down
SendMessage({
  type: "shutdown_request",
  recipient: "worker-1",
  content: "Task complete, wrapping up session"
})
# ... for each worker ...

# 2. Workers respond with shutdown_response (approve/reject)
# 3. Once all workers shut down, cleanup team
TeammateTool({ operation: "cleanup" })

# 4. Complete coordinator work
swarm_complete({
  project_key: "$PWD",
  agent_name: "coordinator",
  bead_id: "<epic-id>",
  summary: "<what was accomplished>",
  files_touched: [...]
})

IMPORTANT: cleanup fails if team still has active members. Gracefully terminate teammates first.

Task Fallback Mode

# Workers complete and exit automatically
swarm_complete({
  project_key: "$PWD",
  agent_name: "<your-name>",
  bead_id: "<epic-id>",
  summary: "<what was accomplished>",
  files_touched: [...]
})

11. Create PR (unless --to-main)

gh pr create --title "feat: <epic title>" --body "## Summary\n<bullets>\n\n## Subtasks\n<list>"

Mode-Specific Tools Quick Reference

Native Teams Mode

Tool	Purpose
TeammateTool	Create team, cleanup after completion
EnterPlanMode	Enter read-only planning (no edits allowed)
ExitPlanMode	Exit planning, ready to implement
SendMessage	Send message to teammate or broadcast
TaskCreate	Create UI task (spinners for user visibility)
TaskUpdate	Update task status, claim ownership
TaskList	View shared task list

Task Fallback Mode

Tool	Purpose
Task	Spawn subagent worker
TaskCreate	Create UI task (spinners)
TaskUpdate	Update task status
swarmmail_send	Send message to agents
swarmmail_inbox	Check inbox (max 5, no bodies)

Both Modes (Plugin Tools)

Tool	Purpose
swarmmail_init	Initialize session (REQUIRED FIRST)
swarmmail_reserve	Reserve files for exclusive editing
swarmmail_release	Release file reservations
hivemind_find	Search semantic memory
hivemind_store	Store learnings
swarm_decompose	Generate decomposition prompt
swarm_validate_decomposition	Validate CellTree JSON
swarm_review	Generate review prompt
swarm_review_feedback	Approve/reject worker output
swarm_complete	Complete with verification
hive_create_epic	Create epic + subtasks (git-backed)

Strategy Reference

Strategy	Best For	Keywords
file-based	Refactoring, migrations	refactor, migrate, rename, update all
feature-based	New features	add, implement, build, create, new
risk-based	Bug fixes, security	fix, bug, security, critical, urgent

Context Preservation Rules

These are NON-NEGOTIABLE. Violating them burns context and kills long swarms.

Rule	Why
Delegate planning to subagent	Decomposition reasoning + file reads consume huge context
Never read 10+ files inline	Use subagent to read + summarize
Use swarmmail_inbox carefully	Max 5 messages, no bodies by default
Receive JSON only from planner	No analysis, no file contents, just structure

Pattern: Delegate → Receive Summary → Act

Not: Do Everything Inline → Run Out of Context → Fail

Quick Checklist

Pre-Flight

• Environment check - detect mode (native-teams vs task-fallback)
• swarmmail_init called FIRST
• hivemind_find queried for prior learnings (MANDATORY)
• Researcher spawned if needed for unfamiliar tech

Planning Phase

• Mode-aware planning (EnterPlanMode OR Task subagent, NOT inline)
• CellTree validated (no file conflicts)
• Epic + subtasks created with hive_create_epic
• UI tasks created with TaskCreate (both modes)

Execution Phase

• Coordinator did NOT reserve files (workers do this)
• Custom prompts include hivemind steps (see 6.5)
• Workers spawned in parallel (single message, multiple spawns)
• Mode-aware monitoring (automatic in native-teams, poll inbox in fallback)
• All workers reviewed with swarm_review

Completion

• hivemind_store called with learnings (MANDATORY)
• Mode-aware shutdown (SendMessage shutdown_request OR workers exit naturally)
• TeammateTool cleanup (native-teams only)
• PR created (or pushed to main)
• ASCII art session summary
