Custom Workflows

Agent Orchestrator’s plugin architecture and event system enable powerful custom workflows beyond the default CI/PR automation.

Orchestrator Agent Workflows

The orchestrator agent is a special session that manages worker agents. It can:

Spawn multiple agents for a batch of issues
Monitor agent progress and intervene when stuck
Coordinate multi-agent workflows
Handle escalations and notifications

Starting the Orchestrator Agent

ao start my-project

This:

Generates an orchestrator prompt with project context
Launches a Claude Code session in the project directory
Provides the orchestrator with CLI access
Opens the dashboard for monitoring

Orchestrator capabilities:

# Inside orchestrator session
ao status                        # Monitor all sessions
ao batch-spawn my-app 1 2 3 4 5  # Spawn multiple agents
ao send my-app-1 "Fix the tests" # Send instructions
ao session cleanup               # Clean up completed work

Orchestrator Prompt

The orchestrator receives a comprehensive prompt (from orchestrator-prompt.ts):

# See all sessions at a glance
ao status

# Spawn sessions for issues
ao spawn my-project INT-1234
ao batch-spawn my-project INT-1 INT-2 INT-3

# Send message to a session
ao send my-app-1 "Your message here"

Custom Orchestrator Rules

Provide project-specific orchestrator instructions:

projects:
  my-app:
    orchestratorRules: |
      Prefer to batch-spawn related issues together.
      Monitor for stuck agents every 10 minutes.
      If more than 3 agents are stuck, escalate to human.
      When CI fails twice, attach to the session to investigate.
      Clean up merged sessions daily at 6pm.

These rules are injected into the orchestrator prompt and guide its behavior.

CI/CD Integration

GitHub Actions Integration

Trigger agent spawning from CI: .github/workflows/agent-spawn.yml:

name: Spawn Agent for Issue

on:
  issues:
    types: [labeled]

jobs:
  spawn-agent:
    if: github.event.label.name == 'agent-task'
    runs-on: ubuntu-latest
    
    steps:
      - name: Checkout agent-orchestrator
        uses: actions/checkout@v3
        with:
          repository: your-org/agent-orchestrator
          path: agent-orchestrator
      
      - name: Setup Node.js
        uses: actions/setup-node@v3
        with:
          node-version: '20'
      
      - name: Install dependencies
        run: |
          cd agent-orchestrator
          pnpm install
          pnpm build
      
      - name: Spawn agent
        run: |
          cd agent-orchestrator
          ao spawn my-project ${{ github.event.issue.number }}
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

Trigger: Label an issue with agent-task → agent spawns automatically.

GitLab CI Integration

.gitlab-ci.yml:

spawn-agent:
  stage: deploy
  only:
    - issues
  script:
    - ao spawn my-project $CI_ISSUE_IID
  when: manual

Trigger: Click “Run Pipeline” on an issue → spawns agent.

Webhook-Triggered Spawning

Create a webhook server that spawns agents:

// webhook-server.ts
import express from "express";
import { exec } from "child_process";
import { promisify } from "util";

const execAsync = promisify(exec);
const app = express();

app.post("/webhook/spawn", async (req, res) => {
  const { project, issue } = req.body;
  
  try {
    await execAsync(`ao spawn ${project} ${issue}`);
    res.json({ success: true, message: `Spawned agent for ${project}:${issue}` });
  } catch (err) {
    res.status(500).json({ error: err.message });
  }
});

app.listen(4000, () => console.log("Webhook server listening on :4000"));

Trigger from anywhere:

curl -X POST http://localhost:4000/webhook/spawn \
  -H "Content-Type: application/json" \
  -d '{"project": "my-app", "issue": "123"}'

Custom Notification Channels

Slack Notifications

Configure Slack webhook:

notifiers:
  slack:
    plugin: slack
    webhook: ${SLACK_WEBHOOK_URL}
    channel: "#agent-updates"

notificationRouting:
  urgent: [slack]
  action: [slack]
  warning: [slack]
  info: [slack]

Get webhook URL:

Go to https://api.slack.com/messaging/webhooks
Create incoming webhook

Copy URL and set environment variable:

export SLACK_WEBHOOK_URL="https://hooks.slack.com/services/..."

Discord Notifications

Create a custom Discord notifier:

notifiers:
  discord:
    plugin: webhook
    url: ${DISCORD_WEBHOOK_URL}
    method: POST
    headers:
      Content-Type: "application/json"

Discord webhook format:

{
  "content": "Agent fe-1 stuck on issue #123",
  "embeds": [
    {
      "title": "Session fe-1",
      "description": "Agent has been inactive for 10 minutes",
      "color": 15158332,
      "fields": [
        { "name": "Project", "value": "frontend", "inline": true },
        { "name": "Issue", "value": "#123", "inline": true },
        { "name": "Status", "value": "stuck", "inline": true }
      ]
    }
  ]
}

Email Notifications

Create a custom email notifier plugin:

// packages/plugins/notifier-email/src/index.ts
import type { Notifier, PluginModule } from "@composio/ao-core";
import nodemailer from "nodemailer";

export const manifest = {
  name: "email",
  slot: "notifier" as const,
  description: "Email notifications via SMTP",
  version: "0.1.0",
};

export function create(config: { smtp: string; from: string; to: string }): Notifier {
  const transporter = nodemailer.createTransport(config.smtp);
  
  return {
    name: "email",
    async notify(notification) {
      await transporter.sendMail({
        from: config.from,
        to: config.to,
        subject: `[Agent Orchestrator] ${notification.title}`,
        text: notification.message,
      });
    },
  };
}

export default { manifest, create } satisfies PluginModule<Notifier>;

Configure in YAML:

notifiers:
  email:
    plugin: email
    smtp: "smtp://user:[email protected]:587"
    from: "[email protected]"
    to: "[email protected]"

PagerDuty Integration

For urgent escalations:

notifiers:
  pagerduty:
    plugin: webhook
    url: https://events.pagerduty.com/v2/enqueue
    method: POST
    headers:
      Authorization: "Token token=${PAGERDUTY_TOKEN}"
      Content-Type: "application/json"

notificationRouting:
  urgent: [pagerduty]  # Only page for urgent issues
  action: [slack]
  warning: [slack]
  info: []

Advanced Use Cases

1. Coordinated Multi-Agent Workflow

Scenario: Frontend and backend changes for a feature.

# Orchestrator spawns both
ao spawn frontend FEAT-123
ao spawn backend FEAT-123

# Monitor both sessions
ao status

# Coordinate: Wait for backend PR to merge before frontend
ao send fe-123 "Wait for backend PR #456 to merge before creating your PR"

2. Scheduled Batch Processing

Scenario: Process all new issues daily. Cron job:

# crontab -e
0 9 * * * /home/user/scripts/daily-agent-spawn.sh

daily-agent-spawn.sh:

#!/bin/bash
set -e

cd ~/agent-orchestrator

# Get new issues from Linear
ISSUES=$(linear issue list --filter 'status:backlog AND label:ready' --format json | jq -r '.[].identifier')

if [ -z "$ISSUES" ]; then
  echo "No new issues"
  exit 0
fi

# Spawn agents for all issues
echo "$ISSUES" | xargs ao batch-spawn my-project

# Send Slack notification
curl -X POST $SLACK_WEBHOOK_URL \
  -H 'Content-Type: application/json' \
  -d "{\"text\": \"Spawned agents for $(echo $ISSUES | wc -w) issues\"}"

3. Auto-Retry with Escalation

Scenario: Retry failed agents with different prompts.

reactions:
  agent-stuck:
    threshold: 10m
    action: notify
    priority: urgent

Custom escalation script:

#!/bin/bash
# retry-stuck-agent.sh

SESSION=$1
RETRY_COUNT=$(cat ~/.agent-orchestrator/sessions/my-app/$SESSION/retry_count || echo 0)

if [ $RETRY_COUNT -lt 2 ]; then
  # Retry with hint
  ao send $SESSION "You seem stuck. Try breaking the task into smaller steps."
  echo $((RETRY_COUNT + 1)) > ~/.agent-orchestrator/sessions/my-app/$SESSION/retry_count
else
  # Escalate to human
  curl -X POST $SLACK_WEBHOOK_URL \
    -H 'Content-Type: application/json' \
    -d "{\"text\": \"Session $SESSION stuck after 2 retries. Manual intervention needed.\"}"
fi

4. Continuous Monitoring Dashboard

Scenario: Real-time monitoring with Grafana. Export metrics:

#!/bin/bash
# export-metrics.sh

while true; do
  ao status --json > /tmp/agent-status.json
  
  # Parse and send to Prometheus pushgateway
  ACTIVE=$(jq '[.[] | select(.activity == "active")] | length' /tmp/agent-status.json)
  STUCK=$(jq '[.[] | select(.activity == "blocked" or .status == "stuck")] | length' /tmp/agent-status.json)
  
  echo "agent_active $ACTIVE" | curl --data-binary @- http://pushgateway:9091/metrics/job/agent_orchestrator
  echo "agent_stuck $STUCK" | curl --data-binary @- http://pushgateway:9091/metrics/job/agent_orchestrator
  
  sleep 30
done

Grafana alerts:

Alert if agent_stuck > 3
Alert if agent_active == 0 during business hours

5. PR Review Automation

Scenario: Auto-approve low-risk PRs.

reactions:
  approved-and-green:
    auto: true
    action: auto-merge

Custom review script:

#!/bin/bash
# auto-review.sh

PR_NUMBER=$1
PR_DATA=$(gh pr view $PR_NUMBER --json files,additions,deletions)

ADDITIONS=$(echo $PR_DATA | jq '.additions')
DELETIONS=$(echo $PR_DATA | jq '.deletions')
FILES=$(echo $PR_DATA | jq '.files | length')

# Auto-approve if small change
if [ $ADDITIONS -lt 50 ] && [ $DELETIONS -lt 50 ] && [ $FILES -lt 3 ]; then
  gh pr review $PR_NUMBER --approve --body "Auto-approved: Low-risk change"
fi

6. Multi-Repo Coordination

Scenario: Update multiple repos for a breaking API change.

# multi-repo-config.yaml
projects:
  api:
    repo: org/api
    path: ~/api
  
  frontend:
    repo: org/frontend
    path: ~/frontend
  
  mobile:
    repo: org/mobile
    path: ~/mobile

Orchestrator workflow:

# 1. Update API
ao spawn api BREAKING-123
ao send api-1 "Implement breaking change to /auth endpoint"

# 2. Wait for API PR to merge
# (Manual or auto-merge)

# 3. Update dependents
ao spawn frontend BREAKING-123
ao spawn mobile BREAKING-123

ao send fe-1 "Update frontend to use new /auth endpoint"
ao send mob-1 "Update mobile to use new /auth endpoint"

# 4. Coordinate PRs
# Link PRs in GitHub: "Depends on #456"

Event Log Analysis

All events are logged to ~/.agent-orchestrator/events.jsonl:

{"timestamp":"2024-03-04T10:30:00Z","type":"session.spawned","sessionId":"fe-1","projectId":"frontend","issueId":"123"}
{"timestamp":"2024-03-04T10:32:00Z","type":"pr.created","sessionId":"fe-1","prNumber":42}
{"timestamp":"2024-03-04T10:35:00Z","type":"ci.failed","sessionId":"fe-1","prNumber":42}
{"timestamp":"2024-03-04T10:36:00Z","type":"reaction.triggered","reaction":"ci-failed","action":"send-to-agent"}

Query events:

# Count CI failures
jq 'select(.type == "ci.failed") | .sessionId' ~/.agent-orchestrator/events.jsonl | sort | uniq -c

# Find stuck sessions
jq 'select(.type == "session.stuck")' ~/.agent-orchestrator/events.jsonl

# PR creation rate
jq 'select(.type == "pr.created")' ~/.agent-orchestrator/events.jsonl | wc -l

Custom Plugins

Runtime Plugin (Docker Example)

Run agents in Docker containers:

// packages/plugins/runtime-docker/src/index.ts
import type { Runtime, RuntimeHandle, PluginModule } from "@composio/ao-core";
import Docker from "dockerode";

const docker = new Docker();

export const manifest = {
  name: "docker",
  slot: "runtime" as const,
  description: "Runtime plugin: Docker containers",
  version: "0.1.0",
};

export function create(): Runtime {
  return {
    name: "docker",
    
    async create(config) {
      const container = await docker.createContainer({
        Image: "agent-orchestrator:latest",
        Cmd: ["bash"],
        Tty: true,
        WorkingDir: config.workingDir,
      });
      
      await container.start();
      
      return {
        id: container.id,
        runtimeName: "docker",
        data: { containerId: container.id },
      };
    },
    
    async destroy(handle) {
      const container = docker.getContainer(handle.id);
      await container.stop();
      await container.remove();
    },
    
    async sendCommand(handle, command) {
      const container = docker.getContainer(handle.id);
      const exec = await container.exec({
        Cmd: ["bash", "-c", command],
        AttachStdout: true,
        AttachStderr: true,
      });
      await exec.start({});
    },
  };
}

export default { manifest, create } satisfies PluginModule<Runtime>;

Use in config:

defaults:
  runtime: docker

Best Practices

Start simple

Use default reactions and workflows before building custom automation.

Monitor events

Tail the event log to understand system behavior:

tail -f ~/.agent-orchestrator/events.jsonl | jq

Test reactions in isolation

Use a test project to validate custom workflows before production.

Gradual escalation

Start with notifications, add automation as confidence grows.

Preserve audit trail

Never delete event logs or session metadata (disk is cheap).
