Swarm Skill

Spawn isolated agents to execute tasks in parallel. Fresh context per agent (Ralph Wiggum pattern).

Execution Modes:

Local (default) - Runtime-native spawning (Codex sub-agents when available, otherwise Claude teams/task agents)
Distributed (
```
--mode=distributed
```
) - tmux sessions + Agent Mail for robust coordination

Integration modes:

Direct - Create TaskList tasks, invoke
```
/swarm
```
Via Crank -
```
/crank
```
creates tasks from beads, invokes
```
/swarm
```
for each wave

Architecture (Mayor-First)

Mayor (this session)
    |
    +-> Plan: TaskCreate with dependencies
    |
    +-> Identify wave: tasks with no blockers
    |
    +-> Select spawn backend (Codex sub-agents | Claude teams | fallback tasks)
    |
    +-> Assign: TaskUpdate(taskId, owner="worker-<id>", status="in_progress")
    |
    +-> Spawn workers via selected backend
    |       Workers receive pre-assigned task, execute atomically
    |
    +-> Wait for completion (wait() | SendMessage | TaskOutput)
    |
    +-> Validate: Review changes when complete
    |
    +-> Cleanup backend resources (close_agent | TeamDelete | none)
    |
    +-> Repeat: New team + new plan if more work needed

Execution

Given

/swarm

Step 0: Select Local Spawn Backend (MANDATORY)

Use runtime capability detection, not hardcoded assumptions:

If
```
spawn_agent
```
is available, use Codex experimental sub-agents
Else if
```
TeamCreate
```
is available, use Claude native teams
Else use background task fallback (
```
Task(run_in_background=true)
```
)

See

skills/shared/SKILL.md

("Runtime-Native Spawn Backend Selection") for the shared contract used by all orchestration skills.

Step 1: Ensure Tasks Exist

Use TaskList to see current tasks. If none, create them:

TaskCreate(subject="Implement feature X", description="Full details...")
TaskUpdate(taskId="2", addBlockedBy=["1"])  # Add dependencies after creation

Step 2: Identify Wave

Find tasks that are:

Status:
```
pending
```
No blockedBy (or all blockers completed)

These can run in parallel.

Steps 3-6: Spawn Workers, Validate, Finalize

For detailed local mode execution (team creation, worker spawning, race condition prevention, git commit policy, validation contract, cleanup, and repeat logic), read
skills/swarm/references/local-mode.md
.

Example Flow

Mayor: "Let's build a user auth system"

1. /plan -> Creates tasks:
   #1 [pending] Create User model
   #2 [pending] Add password hashing (blockedBy: #1)
   #3 [pending] Create login endpoint (blockedBy: #1)
   #4 [pending] Add JWT tokens (blockedBy: #3)
   #5 [pending] Write tests (blockedBy: #2, #3, #4)

2. /swarm -> Spawns agent for #1 (only unblocked task)

3. Agent #1 completes -> #1 now completed
   -> #2 and #3 become unblocked

4. /swarm -> Spawns agents for #2 and #3 in parallel

5. Continue until #5 completes

6. /vibe -> Validate everything

Key Points

Runtime-native local mode - Auto-selects Codex sub-agents or Claude teams
Universal orchestration contract - Same swarm behavior across Claude and Codex sessions
Pre-assigned tasks - Mayor assigns tasks before spawning; workers never race-claim
Fresh worker contexts - New sub-agents/teammates per wave preserve Ralph isolation
Wave execution - Only unblocked tasks spawn
Mayor orchestrates - You control the flow, workers report via backend channel
Retry via message/input - Use
```
send_input
```
(Codex) or
```
SendMessage
```
(Claude)
Atomic execution - Each worker works until task done
Graceful fallback - If richer APIs unavailable, fall back to
```
Task(run_in_background=true)
```

Integration with AgentOps

This ties into the full workflow:

/research -> Understand the problem
/plan -> Decompose into beads issues
/crank -> Autonomous epic loop
    +-- /swarm -> Execute each wave in parallel
/vibe -> Validate results
/post-mortem -> Extract learnings

Direct use (no beads):

TaskCreate -> Define tasks
/swarm -> Execute in parallel

The knowledge flywheel captures learnings from each agent.

Task Management Commands

# List all tasks
TaskList()

# Mark task complete after notification
TaskUpdate(taskId="1", status="completed")

# Add dependency between tasks
TaskUpdate(taskId="2", addBlockedBy=["1"])

Parameters

Parameter	Description	Default
`--mode=local\|distributed`	Execution mode	`local`
`--max-workers=N`	Max concurrent workers	5
`--from-wave <json-file>`	Load wave from OL hero hunt output (see OL Wave Integration)	-
`--bead-ids`	Specific beads to work (comma-separated, distributed mode)	Auto from `bd ready`
`--wait`	Wait for all workers to complete (distributed mode)	false
`--timeout`	Max time to wait if `--wait` (distributed mode)	30m

When to Use Swarm

Scenario	Use
Multiple independent tasks	`/swarm` (parallel)
Sequential dependencies	`/swarm` with blockedBy
Mix of both	`/swarm` spawns waves, each wave parallel

Why This Works: Ralph Wiggum Pattern

Follows the Ralph Wiggum Pattern: fresh context per execution unit.

Wave-scoped worker set = spawn workers -> execute -> cleanup -> repeat (fresh context each wave)
Mayor IS the loop - Orchestration layer, manages state across waves
Workers are atomic - One task, one spawn, one result
TaskList as memory - State persists in task status, not agent context
Filesystem for artifacts - Files written by workers, committed by team lead
Backend messaging for coordination - Workers report to team lead, never to each other

Integration with Crank

When

/crank

invokes

/swarm

: Crank bridges beads to TaskList, swarm executes with fresh-context agents, crank syncs results back.

You Want	Use	Why
Fresh-context parallel execution	`/swarm`	Each spawned agent is a clean slate
Autonomous epic loop	`/crank`	Loops waves via swarm until epic closes
Just swarm, no beads	`/swarm` directly	TaskList only, skip beads
RPI progress gates	`/ratchet`	Tracks progress; does not execute work

Distributed Mode

For the full distributed mode specification (tmux + Agent Mail, experimental), read
skills/swarm/references/distributed-mode.md
.

OL Wave Integration

When

/swarm --from-wave <json-file>

is invoked, the swarm reads wave data from an OL hero hunt output file and executes it with completion backflow to OL.

Pre-flight

bash

# --from-wave requires ol CLI on PATH
which ol >/dev/null 2>&1 || {
    echo "Error: ol CLI required for --from-wave. Install ol or use swarm without wave integration."
    exit 1
}

ol

is not on PATH, exit immediately with the error above. Do not fall back to normal swarm mode.

Input Format

The

--from-wave

JSON file contains

ol hero hunt

output:

json

{
  "wave": [
    {"id": "ol-527.1", "title": "Add auth middleware", "spec_path": "quests/ol-527/specs/ol-527.1.md", "priority": 1},
    {"id": "ol-527.2", "title": "Fix rate limiting", "spec_path": "quests/ol-527/specs/ol-527.2.md", "priority": 2}
  ],
  "blocked": [
    {"id": "ol-527.3", "title": "Integration tests", "blocked_by": ["ol-527.1", "ol-527.2"]}
  ],
  "completed": [
    {"id": "ol-527.0", "title": "Project setup"}
  ]
}

Execution

Parse the JSON file and extract the
```
wave
```
array.
Create TaskList tasks from wave entries (one
```
TaskCreate
```
per entry):

for each entry in wave:
    TaskCreate(
        subject="[{entry.id}] {entry.title}",
        description="OL bead {entry.id}\nSpec: {entry.spec_path}\nPriority: {entry.priority}\n\nRead the spec file at {entry.spec_path} for full requirements.",
        metadata={
            "ol_bead_id": entry.id,
            "ol_spec_path": entry.spec_path,
            "ol_priority": entry.priority
        }
    )

Execute swarm normally on those tasks (Step 2 onward from main execution flow). Tasks are ordered by priority (lower number = higher priority).
Completion backflow: After each worker completes a bead task AND passes validation, the team lead runs the OL ratchet command to report completion back to OL:

bash

# Extract quest ID from bead ID (e.g., ol-527.1 -> ol-527)
QUEST_ID=$(echo "$BEAD_ID" | sed 's/\.[^.]*$//')

ol hero ratchet "$BEAD_ID" --quest "$QUEST_ID"

Ratchet result handling:

Exit Code	Meaning	Action
0	Bead complete in OL	Mark task completed, log success
1	Ratchet validation failed	Mark task as failed, log the validation error from stderr

After all wave tasks complete, report a summary that includes both swarm results and OL ratchet status for each bead.

Example

/swarm --from-wave /tmp/wave-ol-527.json

# Reads wave JSON -> creates 2 tasks from wave entries
# Spawns workers for ol-527.1 and ol-527.2
# On completion of ol-527.1:
#   ol hero ratchet ol-527.1 --quest ol-527 -> exit 0 -> bead complete
# On completion of ol-527.2:
#   ol hero ratchet ol-527.2 --quest ol-527 -> exit 0 -> bead complete
# Wave done: 2/2 beads ratcheted in OL
