Workflows

Workflows let you chain agents, tools, and control logic into repeatable automations. They come in two flavours: background (autonomous, trigger-driven) and chat (interactive, human-in-the-loop).

Creating Your First Workflow

1. Click the ⚙ gear icon next to Workflows in the sidebar, then click New Workflow.
2. Give it a name (e.g. user/daily-digest) and pick a mode — Background or Chat.
3. Add a trigger — what kicks the workflow off (schedule, event, or manual).
4. Add steps — the work the workflow actually does.
5. Save and launch it. Background workflows are launched from the definitions view (click the Launch button). Chat workflows are launched from the Chat view using the workflow button in the composer toolbar.

Visual Designer vs YAML Editor

HiveMind OS gives you three ways to build workflows:

• Visual designer — drag-and-drop step nodes onto a canvas and connect them. Great for exploring what's possible.
• YAML editor — write the workflow definition directly. Faster for power users and easy to version-control.
• AI generation — describe what you want in natural language and let HiveMind OS generate the YAML for you.

TIP

Start in the visual designer to learn the step types, then switch to YAML once you're comfortable — the two stay in sync automatically.

Background Workflows

Background workflows run autonomously without user interaction. They're ideal for automations that should just happen.

Triggers

Trigger	Description
manual	Triggered manually by a user (optionally with an input schema)
schedule	Cron expression (e.g. "0 9 * * 1-5" for weekdays at 9 AM)
event_pattern	Fires on internal event bus topics
incoming_message	Fires on messages from a connector (email, Slack, Discord, etc.)

Monitoring

Every run creates an instance visible on the Workflows page. From there you can inspect status, step-by-step logs, and output values in real time.

Example: Daily Standup Summary

name: user/daily-standup
mode: background
steps:
  - id: trigger
    type: trigger
    trigger:
      type: schedule
      cron: "0 9 * * 1-5"
  - id: gather
    type: task
    task:
      kind: invoke_agent
      persona_id: user/project-manager
      task: "Summarize yesterday's git commits and open PRs for the team"
    outputs:
      summary: "{{result}}"
  - id: notify
    type: task
    task:
      kind: call_tool
      tool_id: comm.send_external_message
      arguments:
        channel: "#standup"
        body: "{{steps.gather.outputs.summary}}"

More ideas: automated code scanning, nightly report generation, data pipeline orchestration.

Chat Workflows

Chat workflows run inside a conversation. They can pause to ask questions, present choices, and wait for approval before continuing.

Key Capabilities

• Feedback gates — pause execution and ask the user to confirm or choose.
• Interactive data gathering — collect inputs step-by-step through the chat.
• Result messages — display a formatted summary when the workflow completes.

Example: Guided Project Setup

name: user/project-setup
mode: chat
steps:
  - id: trigger
    type: trigger
    trigger:
      type: manual
      input_schema:
        type: object
        properties:
          projectName:
            type: string
  - id: ask_stack
    type: task
    task:
      kind: invoke_agent
      persona_id: user/developer
      task: "What tech stack should we use for {{trigger.input.projectName}}?"
  - id: confirm
    type: task
    task:
      kind: feedback_gate
      prompt: "Here's my recommendation. Shall I proceed?"
  - id: setup
    type: task
    task:
      kind: invoke_agent
      persona_id: user/developer
      task: "Set up project {{trigger.input.projectName}} with the agreed stack"
    outputs:
      result: "{{result}}"
result_message: "{{steps.setup.outputs.result}}"

Step Types Reference

Every step has a type (trigger, task, or control_flow) and a kind that determines what it does.

Task Kinds

Kind	What it does
call_tool	Invoke any MCP tool by tool_id with arguments
invoke_agent	Spawn an agent with a persona and a task prompt
invoke_prompt	Resolve a persona's prompt template with parameters
feedback_gate	Pause and ask the user for confirmation or input (chat mode)
event_gate	Pause until a specific event arrives on a topic
launch_workflow	Start another workflow, optionally passing inputs
schedule_task	Register a cron-scheduled action
delay	Wait for duration_secs before continuing
set_variable	Assign, append, or merge values into workflow variables
signal_agent	Send a message to a running agent or session

Control Flow

Use type: control_flow steps to add branching and iteration.

Branch

- id: check_size
  type: control_flow
  control:
    kind: branch
    condition: "{{steps.analyze.outputs.lines}} > 500"
    then: [deep_review]
    else: [quick_review]

For Each

- id: process_files
  type: control_flow
  control:
    kind: for_each
    collection: "{{steps.list.outputs.files}}"
    item_var: current_file
    body: [lint_file]

While

- id: poll
  type: control_flow
  control:
    kind: while
    condition: "{{variables.status}} != 'ready'"
    max_iterations: 10
    body: [check_status, wait]

Error Handling

Attach an on_error strategy to any step:

Strategy	Behaviour
retry	Retry up to max_retries times with delay_secs between attempts
skip	Skip the step and optionally provide a default_output
goto	Jump to a specific step_id
fail_workflow	Abort the workflow with an optional message

- id: flaky_api
  type: task
  task:
    kind: call_tool
    tool_id: fetch_data
    arguments:
      url: "https://api.example.com/data"
  on_error:
    strategy: retry
    max_retries: 3
    delay_secs: 10

Variables and Data Flow

Workflows pass data between steps using template expressions.

• {{steps.<id>.outputs.<field>}} — a named output from a completed step.
• {{trigger.input.<field>}} — an input value from the trigger (manual triggers).
• {{trigger.<field>}} — trigger data (e.g., {{trigger.from}}, {{trigger.body}} for incoming messages).
• {{variables.<name>}} — a workflow-scoped variable set by set_variable steps.

Use a set_variable step to accumulate or transform data mid-workflow:

- id: save_result
  type: task
  task:
    kind: set_variable
    assignments:
      - variable: summary
        value: "{{steps.gather.outputs.summary}}"
        operation: set

The operation field supports set (overwrite), append_list (add to an array), and merge_map (shallow-merge into an object).

TIP

Keep workflows focused on orchestration. Put complex logic inside agent prompts or dedicated tools — workflows are the glue that connects them.

Launching Workflows

Background and chat workflows are launched from different places in the UI.

Launching Background Workflows

Background workflows are launched from the workflow definitions view (⚙ gear icon next to Workflows in the sidebar):

1. Open the definitions view and find your workflow
2. Click the Launch button on the workflow definition
3. If the workflow has multiple manual triggers, pick which one to use
4. Fill in any required inputs (shown as a form generated from the input_schema, or as a JSON editor for complex inputs)
5. Review and click Launch — the workflow starts immediately

The running instance appears on the Workflows page (click Workflows in the sidebar) where you can track its progress in real time.

Launching Chat Workflows

Chat workflows are launched from the Chat view using the workflow button in the message composer:

1. Open the Chat view and start or select a conversation
2. Click the Launch a chat workflow button in the composer toolbar
3. A dialog opens with a searchable list of available chat workflows — pick the one you want
4. If the workflow has multiple manual triggers, choose which one to use
5. Fill in any required inputs and click Launch
6. The workflow attaches to your conversation — agent steps produce messages in the thread, and feedback_gate steps pause to present you with choices or a text input
7. Your responses feed back into the workflow, and execution continues

This makes chat workflows ideal for guided processes — onboarding, approval flows, interactive research — where you need to participate at key moments.

Automatic Triggers

Workflows with non-manual triggers activate automatically once saved:

Trigger	When it fires
schedule	At the next matching cron time (e.g., "0 9 * * 1-5" fires weekdays at 9 AM)
event_pattern	When a matching event is published on the internal event bus
incoming_message	When a message arrives on the specified connector channel

You can pause triggers on any workflow without deleting it — the workflow stays saved but won't fire until you resume triggers. Toggle this from the workflow's detail panel.

Launching from Within a Workflow

Use the launch_workflow step kind to start one workflow from another:

- id: run_subreport
  type: task
  task:
    kind: launch_workflow
    workflow_name: user/generate-report
    inputs:
      date_range: "{{variables.date_range}}"

This is how you compose small, focused workflows into larger automations — each workflow handles one concern.

Managing Running Workflows

Every workflow launch creates an instance — a running copy of the workflow definition with its own state, variables, and progress.

Monitoring

Open the Workflows page to see all active and completed instances:

• Status — Running, Paused, Waiting (at a gate), Completed, or Failed
• Step progress — see which step is currently executing and review outputs from completed steps
• Live updates — the page updates in real time as steps complete

Flight Deck

For a global view of all running workflows and agents in one place, open the Flight Deck — click the 🚀 rocket button in the top-right corner. See the No-Code Guide for details.

Responding to Gates

When a running workflow reaches a feedback_gate, it pauses and waits for your input. In chat workflows, the gate appears as a message in your conversation. For background workflows, the gate surfaces on the Workflows page as a pending action.

When a workflow hits an event_gate, it waits for the specified event. If you configured a timeout and it expires, the step completes with a timeout payload (error: "event_gate_timeout") — you can branch on this in a subsequent step to handle the timeout gracefully.

Pause, Resume, and Kill

From the workflow instance detail panel:

• Pause — temporarily suspend execution. The workflow keeps its state and can be resumed later.
• Resume — continue a paused workflow from where it left off.
• Kill — immediately terminate the workflow. This cannot be undone.

Archiving

Completed or failed instances can be archived to keep your Workflows page clean. Archived instances are hidden from the default view but can still be reviewed.

Bundled Workflows

HiveMind OS ships with several ready-to-use workflows. You can launch them directly, or copy and customize them to fit your needs.

Browsing Bundled Workflows

Click the ⚙ gear icon next to Workflows in the sidebar to open the definitions view — bundled workflows appear alongside your custom workflows with a system/ prefix. Click any workflow to view its definition, then:

• Launch — run it immediately with the default or your own inputs
• Copy — create a new workflow using New Workflow → Copy from existing to get an editable copy under your user/ namespace

Available Bundled Workflows

Workflow	ID	Mode	What it does
Approval Workflow	system/approval-workflow	Chat	Submit a request with a title, description, and urgency. An AI agent analyzes it, then a feedback gate lets you approve, request changes, or reject. Demonstrates branching based on user decisions.
Email Responder	system/email-responder	Background	Auto-replies to incoming customer emails using a support agent persona with access to uploaded product documentation.
Email Triage	system/email-triage	Background	Classifies and routes incoming emails by intent — product questions, bug reports, billing issues — and takes appropriate action for each category.
Plan and Implement	system/software/plan-and-implement	Chat	A two-phase workflow: first an AI agent creates a plan, then (after your approval via a feedback gate) another agent implements it. Includes a review loop.
Software Feature	system/software/major-feature	Chat	Full software development lifecycle — optional spec writing, technical research/POC, planning, implementation, and documentation. Each phase has a feedback gate for human review, with while loops that let you request revisions.
3D Print Design	system/3d-print/design	Chat	Guides a 3D print CAD design workflow using specialized personas for modeling and analysis.

Start with Approval Workflow

The Approval Workflow is the simplest bundled workflow and a great way to see feedback gates, branching, and variables in action. Launch it from the definitions view to try it out.

Creating a Custom Workflow from Scratch

This walkthrough takes you from an idea to a running workflow. We'll build a support ticket triage workflow that classifies incoming messages and routes them to the right team.

Step 1: Define Your Use Case

Before opening the editor, decide:

• What triggers the workflow? → An incoming message on the support channel
• What should happen? → Classify the message, then route it
• Does a human need to be involved? → Not for classification, but yes for edge cases
• Background or chat? → Background — this should run automatically

Step 2: Create the Workflow

1. Open the workflow definitions view (⚙ gear icon next to Workflows in the sidebar) and click New Workflow
2. Name it user/support-triage
3. Set mode to Background

Step 3: Add the Trigger

Start with the incoming message trigger:

name: user/support-triage
mode: background

steps:
  - id: trigger
    type: trigger
    trigger:
      type: incoming_message
      channel_id: support-inbox
      ignore_replies: true
    next: [classify]

Step 4: Add Classification

Use an invoke_agent step to classify the message. Note how trigger data for incoming messages is accessed directly as {{trigger.from}}, {{trigger.subject}}, {{trigger.body}}, etc.

  - id: classify
    type: task
    task:
      kind: invoke_agent
      persona_id: user/support-classifier
      task: |
        Classify this support message into one category:
        - bug_report
        - feature_request
        - billing
        - general_question

        From: {{trigger.from}}
        Subject: {{trigger.subject}}
        Body: {{trigger.body}}

        Return a JSON object with:
        - "category": one of the above categories
      timeout_secs: 60
    outputs:
      category: "{{result.category}}"
    on_error:
      strategy: skip
      default_output:
        category: "general_question"
    next: [route]

Step 5: Add Routing with Branches

Use a branch step to handle each category differently:

  - id: route
    type: control_flow
    control:
      kind: branch
      condition: "{{steps.classify.outputs.category}} == billing"
      then: [forward_to_billing]
      else: [auto_respond]

Step 6: Add the Action Steps

  - id: forward_to_billing
    type: task
    task:
      kind: call_tool
      tool_id: connector.send_message
      arguments:
        channel_id: billing-team
        to: "{{trigger.from}}"
        subject: "Billing inquiry: {{trigger.subject}}"
        body: "Forwarded billing inquiry from {{trigger.from}}:\n\n{{trigger.body}}"
    next: [end]

  - id: auto_respond
    type: task
    task:
      kind: invoke_agent
      persona_id: user/support-agent
      task: |
        Reply to this {{steps.classify.outputs.category}} message:
        From: {{trigger.from}}
        Subject: {{trigger.subject}}
        Body: {{trigger.body}}

        Write a helpful response. Return ONLY the reply text.
      timeout_secs: 120
    outputs:
      reply: "{{result}}"
    next: [send_reply]

  - id: send_reply
    type: task
    task:
      kind: call_tool
      tool_id: connector.send_message
      arguments:
        channel_id: support-inbox
        to: "{{trigger.from}}"
        subject: "Re: {{trigger.subject}}"
        body: "{{steps.auto_respond.outputs.reply}}"
    on_error:
      strategy: retry
      max_retries: 3
      delay_secs: 5
    next: [end]

  - id: end
    type: control_flow
    control:
      kind: end_workflow

Step 7: Test It

1. Save the workflow
2. To test before real messages arrive, click Launch from the definitions view (⚙ gear icon) — you'll be prompted to provide test input as JSON (e.g., {"from": "test@example.com", "subject": "Billing help", "body": "I need an invoice"})
3. Watch the instance execute on the Workflows page (click Workflows in the sidebar) — click into it to see step-by-step progress
4. Check that the classification is correct and the response makes sense

Step 8: Activate

Once you're happy with the results, the workflow will automatically fire on new incoming messages on the support-inbox channel. You can pause triggers at any time without deleting the workflow.
