Openclaw Agent Swarm

Agent Swarm

Run coding tasks asynchronously in isolated git worktrees with automatic status tracking, Definition of Done (DoD) validation, and PR creation.

What This Skill Does

This skill spawns coding agents (codex, claude, or gemini) in isolated git worktrees running inside tmux sessions. Each task runs independently in the background, allowing you to work on multiple features or fixes in parallel without blocking your main workflow.

Key capabilities:

• Spawn tasks in isolated worktrees (no conflicts with your main branch)
• Two modes: interactive (you can send follow-up messages) or batch (fire-and-forget)
• Automatic status tracking and change notifications
• Definition of Done validation (dod_spec: status/clean/commit/CI checks)
• Automatic git push and PR/MR creation when tasks complete
• Follow-up tasks that reuse or create new worktrees

When to Use This Skill

Use this skill when you need to:

• Run multiple coding tasks in parallel without blocking each other
• Execute long-running tasks in the background while you continue working
• Isolate experimental changes in separate worktrees
• Automatically validate task completion with CI commands
• Create PRs/MRs automatically after task completion

Don't use this for:

• Simple, quick edits in your current directory (just do them directly)
• Tasks that need immediate interactive feedback (unless using interactive mode)
• Non-git repositories (this skill requires git)

Prerequisites

Before using this skill, verify these tools are installed:

• git (required)
• tmux (required)
• At least one agent: codex, claude, or gemini (required)
• Runtime for executing swarm.ts: bun (preferred) or npx (fallback to npx -y tsx@4.20.6)
• Optional: gh (GitHub CLI) or glab (GitLab CLI) for automatic PR creation

Resolve ${RUN_X} runtime once in your shell:

if command -v bun >/dev/null 2>&1; then
  RUN_X=(bun)
elif command -v npx >/dev/null 2>&1; then
  RUN_X=(npx -y tsx@4.20.6)
else
  echo "runtime is required. Install bun or npx (for tsx fallback)." >&2
  exit 1
fi

Quick Start

# Spawn a task (returns immediately with task ID)
"${RUN_X[@]}" "$SKILL_DIR/scripts/swarm.ts" spawn \
  --repo /path/to/your/repo \
  --task "Add error handling to the login function" \
  --mode batch

See Common Workflows below for detailed usage patterns.

Core Concepts

Task Modes

Batch mode (default):

• Agent runs the prompt once and exits
• Task succeeds if exit code is 0, fails otherwise
• Best for: well-defined tasks, automated workflows, CI-like operations

Interactive mode:

• Agent stays running, you can send follow-up messages via attach
• Task stays in running or pending state until you manually stop it
• Best for: exploratory work, iterative refinement, complex debugging

Task Status Lifecycle

running ↔ pending → success/failed/stopped (terminal states)

• running: Agent is actively working
• pending: Interactive mode, agent waiting for input
• success: Batch mode completed with exit code 0
• failed: Task failed (non-zero exit code or error)
• stopped: Task was cancelled or tmux session died

Definition of Done (DoD)

DoD is evaluated automatically when task status transitions to pending or success:

Default DoD checks:

1. Current status is in dod_spec.checks.allowed_statuses (default: pending, success)
2. Worktree is clean (default enabled)
3. Optional: current branch has commits ahead of base_branch
4. All dod_spec.checks.ci_commands pass (if specified)
5. On success only: execute dod_spec.actions.push_command and dod_spec.actions.pr_command (if non-empty)

Notes:

• If you do not want auto-push, set dod_spec.actions.push_command to an empty string.
• If dod_spec.actions.push_command and/or dod_spec.actions.pr_command is empty, only remind/suggest manual publish/create-pr; do not auto-run those commands.
• For GitHub CLI, a common PR command is gh pr create --fill --base main --head "$(git rev-parse --abbrev-ref HEAD)".

DoD status:

• pass: Task completed successfully and met all criteria
• fail: Task didn't meet DoD criteria

Only tasks with dod.status=pass can be published.

Follow-up Tasks

When a task fails or needs more work, spawn a follow-up:

New session (--session-mode new):

• Reuses the same worktree but starts fresh agent session
• Use when you want a clean slate but keep the code changes

Reuse session (--session-mode reuse):

• Continues the previous agent's conversation
• Use when you want to build on the previous context
• Must use the same agent as parent task

Script Locations

Determine SKILL_DIR as the directory containing this SKILL.md file.

• Main script: $SKILL_DIR/scripts/swarm.ts
• Check wrapper: $SKILL_DIR/scripts/check-agents.sh
• DoD spec example: $SKILL_DIR/references/dod.json
• State format: $SKILL_DIR/references/state-format.md (JSON schemas)

Agent Behavior Guidelines

IMPORTANT: Fire-and-Forget Pattern

When using this skill, follow these rules:

1. Spawn and Return: After running spawn, immediately return to the user with the task info (id, status, worktree). Do NOT poll, wait, or loop to check status.

1. Never Proactively Check: The check command is designed for system cron/heartbeat jobs, not for agent-initiated polling. Do NOT call check or status after spawn unless:

• User explicitly asks about task status
• System heartbeat/cron provides check results to you

1. Trust Async Execution: Tasks run independently in background. Your job is to spawn and inform, not to monitor.

1. User-Driven Follow-up: Only query task status when the user asks. Use status --id for specific tasks or list for overview.

Example of Correct Behavior:

User: "帮我并行跑三个任务"
Agent: [spawns 3 tasks, returns immediately]
"已启动 3 个异步任务:
- task-1 (id: 20260323-xxx): Fix bug #123
- task-2 (id: 20260323-yyy): Add dark mode
- task-3 (id: 20260323-zzz): Update deps

任务正在后台运行，如需查看状态请告诉我。"

Commands Reference

Repository Path Resolution (Required)

Before running spawn, resolve --repo using this rule:

1. If user input is an existing absolute/relative directory path, use it directly.
2. If user input is a fuzzy name (for example yyy), search candidate directories by basename (for example any directory named yyy) across likely work roots first.
3. If exactly one git repo candidate is found, report the resolved full path and proceed.
4. If multiple candidates are found, list numbered options and ask the user to reply with the option number only. Do not ask them to type the full path.
5. Only run spawn after this repo path is confirmed.

Suggested search behavior:

• Prioritize current workspace and common project roots (such as ~/projects, ~/work, ~/code) before broad home-directory scans.
• For each candidate, verify it is a git repository before presenting it.

spawn - Create New Task

"${RUN_X[@]}" "$SKILL_DIR/scripts/swarm.ts" spawn \
  --repo  \
  --task "" \
  [--mode interactive|batch] \
  [--agent codex|claude|gemini] \
  [--name ] \
  [--ci-commands ""] \
  [--dod-json '{"checks":{"ci_commands":["npm test"],"require_commits_ahead_base":true}}'] \
  [--dod-json-file "$SKILL_DIR/references/dod.json"]

Parameters:

• --repo: Path to git repository (required)
• --task: Task description for the agent (required)
• --mode: batch (default) or interactive
• --agent: Which agent to use (auto-detected if not specified)
• --name: Custom task ID (auto-generated if not specified)
• --ci-commands: CI commands for DoD (comma/newline separated; repeatable)
• --dod-json: Inline DoD spec JSON object (must use checks/actions fields)
• --dod-json-file: Path to DoD spec JSON file

Output: JSON with task details including id, worktree, branch, tmux_session

Example:

"${RUN_X[@]}" "$SKILL_DIR/scripts/swarm.ts" spawn \
  --repo ~/projects/myapp \
  --task "Fix the memory leak in the cache module" \
  --mode batch \
  --ci-commands "npm run lint,npm test -- --run" \
  --dod-json-file "$SKILL_DIR/references/dod.json"

spawn-followup - Continue Failed/Stopped Task

"${RUN_X[@]}" "$SKILL_DIR/scripts/swarm.ts" spawn-followup \
  --from  \
  --task "" \
  --session-mode new|reuse \
  [--agent codex|claude|gemini] \
  [--name ] \
  [--ci-commands ""] \
  [--dod-json '{"checks":{"allowed_statuses":["pending","success"]}}'] \
  [--dod-json-file "$SKILL_DIR/references/dod.json"]

Parameters:

• --from: Parent task ID (required)
• --task: New instructions for the follow-up (required)
• --session-mode: new (fresh session) or reuse (continue conversation) (required)
• --agent: Agent to use (for new mode; reuse must match parent)
• --name: Custom task ID (auto-generated if not specified)
• --ci-commands: Extra/override CI commands merged into follow-up dod_spec

Example:

# Parent task failed, spawn follow-up with fresh session
"${RUN_X[@]}" "$SKILL_DIR/scripts/swarm.ts" spawn-followup \
  --from 20260316-143022-a1b2c3 \
  --task "The previous attempt failed because of missing imports. Fix the imports and try again." \
  --session-mode new \
  --dod-json-file "$SKILL_DIR/references/dod.json"

attach - Send Message to Interactive Task

"${RUN_X[@]}" "$SKILL_DIR/scripts/swarm.ts" attach \
  --id  \
  --message ""

Only works for interactive mode tasks that are not yet terminal.

Example:

"${RUN_X[@]}" "$SKILL_DIR/scripts/swarm.ts" attach \
  --id 20260316-143022-a1b2c3 \
  --message "Also add unit tests for the new function"

check - System Heartbeat Task (NOT for Agent Polling)

This command is designed for system cron/heartbeat jobs only. Agents should NOT call this.

# For system heartbeat/cron only:
bash "$SKILL_DIR/scripts/check-agents.sh"

Or directly:

"${RUN_X[@]}" "$SKILL_DIR/scripts/swarm.ts" check --changes-only

What it does:

• Refreshes status for non-terminal tasks when needed:
• interactive: tmux session is gone, or log has been quiet long enough
• batch: running duration reaches timeout threshold
• Returns only tasks that changed status since last check
• Updates DoD when tasks reach terminal status
• Archives old terminal tasks (default: 24 hours)
• Tracks reminder counts for long-running/pending tasks

When agents receive check results:

• System heartbeat runs check-agents.sh periodically
• If tasks changed status, heartbeat passes results to agent
• Agent can then notify user about completed/failed tasks

DO NOT call check after spawn. Let system heartbeat handle it.

status - Get Task Details

# Get specific task (always refreshes status)
"${RUN_X[@]}" "$SKILL_DIR/scripts/swarm.ts" status --id 

# Search by query (branch name, task description, etc.)
"${RUN_X[@]}" "$SKILL_DIR/scripts/swarm.ts" status --query "login"

# Get latest 10 tasks (no refresh)
"${RUN_X[@]}" "$SKILL_DIR/scripts/swarm.ts" status

Output: Task summary with next_step guidance in Chinese.

list - Show All Active Tasks

"${RUN_X[@]}" "$SKILL_DIR/scripts/swarm.ts" list

Returns all tasks in ~/.agents/agent-swarm/tasks/ (excludes archived tasks).

publish - Push Branch to Remote

"${RUN_X[@]}" "$SKILL_DIR/scripts/swarm.ts" publish \
  --id  \
  [--remote origin] \
  [--target-branch main] \
  [--auto-pr] \
  [--title "PR title"] \
  [--body "PR description"]

Requirements:

• Task must have dod.status=pass

With --auto-pr: Automatically creates PR/MR after successful push.

create-pr - Create PR/MR

"${RUN_X[@]}" "$SKILL_DIR/scripts/swarm.ts" create-pr \
  --id  \
  [--remote origin] \
  [--target-branch main] \
  [--title "PR title"] \
  [--body "PR description"]

Pushes branch first, then creates PR using gh (GitHub) or glab (GitLab) if available. Falls back to manual URL if CLI not found.

cancel - Stop Running Task

"${RUN_X[@]}" "$SKILL_DIR/scripts/swarm.ts" cancel \
  --id  \
  [--reason "why you're cancelling"]

Kills the tmux session and sets task status:

• Usually stopped
• success when task is interactive and currently pending

Common Workflows

Workflow 1: Simple Batch Task (Fire-and-Forget)

# Spawn task and return immediately
"${RUN_X[@]}" "$SKILL_DIR/scripts/swarm.ts" spawn \
  --repo ~/projects/myapp \
  --task "Add logging to the payment processor" \
  --mode batch

# Returns: {"id": "20260323-xxx", "status": "running", ...}
# Agent should inform user and STOP HERE. No polling.

Later, when user asks or heartbeat provides check results:

# User asks: "任务完成了吗？"
"${RUN_X[@]}" "$SKILL_DIR/scripts/swarm.ts" status --id 20260323-xxx

# Or heartbeat/cron runs and provides changes:
# System runs: bash "$SKILL_DIR/scripts/check-agents.sh"
# If task changed, agent receives the info and can notify user

# When task succeeded, user may want to publish:
"${RUN_X[@]}" "$SKILL_DIR/scripts/swarm.ts" publish \
  --id 20260323-xxx \
  --auto-pr

Workflow 2: Interactive Task (User-Driven)

# 1. Spawn interactive task
"${RUN_X[@]}" "$SKILL_DIR/scripts/swarm.ts" spawn \
  --repo ~/projects/myapp \
  --task "Refactor the authentication module" \
  --mode interactive
# Returns immediately with task id

Later, when user provides follow-up instructions:

# User says: "让 agent 也更新测试"
"${RUN_X[@]}" "$SKILL_DIR/scripts/swarm.ts" attach \
  --id  \
  --message "Also update the tests to match the new structure"

When user wants to finish:

# User asks: "完成了吗？帮我停止"
"${RUN_X[@]}" "$SKILL_DIR/scripts/swarm.ts" status --id 
"${RUN_X[@]}" "$SKILL_DIR/scripts/swarm.ts" cancel --id 

# If DoD passes, publish
"${RUN_X[@]}" "$SKILL_DIR/scripts/swarm.ts" publish --id  --auto-pr

Workflow 3: Parallel Tasks (Fire-and-Forget)

# Spawn multiple tasks - return immediately after all spawns
"${RUN_X[@]}" "$SKILL_DIR/scripts/swarm.ts" spawn \
  --repo ~/projects/myapp \
  --task "Fix bug #123 in checkout flow" \
  --mode batch

"${RUN_X[@]}" "$SKILL_DIR/scripts/swarm.ts" spawn \
  --repo ~/projects/myapp \
  --task "Add dark mode support to settings page" \
  --mode batch

"${RUN_X[@]}" "$SKILL_DIR/scripts/swarm.ts" spawn \
  --repo ~/projects/myapp \
  --task "Update dependencies to latest versions" \
  --mode batch

# Returns: 3 task IDs. Agent informs user and STOPS.
# DO NOT call check here. Let system heartbeat handle it.

When user asks status or heartbeat provides updates:

"${RUN_X[@]}" "$SKILL_DIR/scripts/swarm.ts" list
# Or for specific task:
"${RUN_X[@]}" "$SKILL_DIR/scripts/swarm.ts" status --id 

Workflow 4: Failed Task Recovery

# 1. Task failed, check what happened
"${RUN_X[@]}" "$SKILL_DIR/scripts/swarm.ts" status --id 

# 2. Read the log to understand the failure
cat ~/.agents/agent-swarm/logs/.log | tail -100

# 3. Spawn follow-up with fix instructions
"${RUN_X[@]}" "$SKILL_DIR/scripts/swarm.ts" spawn-followup \
  --from  \
  --task "The test failed because of missing mock data. Add the mock data and rerun tests." \
  --session-mode new \
  --dod-json-file "$SKILL_DIR/references/dod.json"

How It Works

Tasks run in isolated git worktrees inside tmux sessions. For internal architecture details (directory structure, task state JSON, DoD evaluation), see $SKILL_DIR/references/architecture.md.

Advanced Usage

For advanced patterns (custom DoD, worktree reuse, automatic reminders), see $SKILL_DIR/references/advanced.md.

Integration with Heartbeat/Cron

Add this to your HEARTBEAT.md or cron:

bash "$SKILL_DIR/scripts/check-agents.sh"

This returns JSON with changes array showing tasks that changed status.
