ArchAstro Workflow Builder

Create, edit, and deploy workflows — multi-step processes that agents execute via routines.

This skill assumes the ArchAgent CLI is already installed and authenticated. Install or upgrade archagent if missing, and run archagent auth login <email> if not authenticated.

What is a Workflow?

A workflow is a directed graph of nodes that defines a multi-step process. Use the dedicated top-level workflow resource for authoring: archagent list workflows, describe workflow, create workflow, update workflow, validate workflow, and describe workflowdocs. Workflows are then attached to agent routines for execution.

Always Start with State

Every invocation must begin by understanding the current context:

archagent auth status
archagent list agents

Determine:

• Which agent will run this workflow?
• Is this a new workflow or an update to an existing one?
• What trigger should start it? (schedule, webhook, manual, message event)

Routing

Workflow commands not exposed in the current archagent build

The source tree has dedicated top-level workflow commands, but some archagent builds may not expose them yet. Verify first:

archagent list workflows
archagent describe workflowdocs

If those commands are unavailable, do not keep insisting on them. Fall back to the config-managed workflow path and explain that the dedicated workflow resource exists in source but is not wired into the current binary.

User wants to create a new workflow

Phase 1: Gather requirements

Understand the workflow before writing any config:

• What triggers it? (cron schedule, webhook, message, manual)
• What are the steps? (in plain language)
• Are there branches or conditions?
• Does it need to call external APIs?
• Does it need to send emails, Slack messages, or other notifications?
• Does it loop over a collection?

Discover available events to understand what can trigger the workflow and what data the trigger provides:

archagent list events

Once the user picks an event type, show them the payload schema so they know what $ contains in downstream scripts:

archagent describe event <event-name>

This returns the JSON schema and a sample payload. The payload fields are accessible via $ in scripts (e.g., $.thread_id, $.message.content).

Phase 2: Scaffold the workflow

Use the top-level workflow commands, not describe configsample/validate config, for the normal authoring loop when the current archagent build exposes them.

Create a workflow from a local JSON file:

archagent create workflow --id my-workflow --file ./workflows/my-workflow.json

Or let the CLI start from its built-in sample if you do not pass --graph or --file:

archagent create workflow --id my-workflow

Phase 3: Author the workflow

A workflow is a WorkflowGraph JSON config under the hood, but the user-facing authoring path should go through the top-level workflow commands.

A minimal workflow graph looks more like:

{
  "kind": "WorkflowGraph",
  "version": 1,
  "name": "My Workflow",
  "start_node": "trigger_1",
  "nodes": [
    {
      "kind": "WorkflowTrigger",
      "id": "trigger_1",
      "trigger": "workflow.scheduled",
      "on_success": "script_1"
    },
    {
      "kind": "WorkflowScript",
      "id": "script_1",
      "script": "default-script"
    }
  ],
  "data": [
    {
      "kind": "Script",
      "id": "default-script",
      "script": "true"
    }
  ]
}

Use the live workflow docs when the graph shape is unclear:

archagent describe workflowdocs

If workflowdocs is not available in the current binary, say so explicitly and fall back to the config-managed path instead of pretending the command exists.

Available node types

Do not hard-code a node taxonomy in this skill. The supported graph/node model is owned by the workflow implementation and archagent describe workflowdocs.

Phase 4: Write supporting scripts

If the workflow needs script logic, author and validate that script first. Route to the build-script skill for detailed script authoring guidance, or get the reference directly:

archagent describe scriptdocs
archagent describe configsample Script

Phase 5: Validate

Validate the workflow graph through the dedicated workflow command:

archagent validate workflow --file ./workflows/my-workflow.json

Validate any referenced scripts:

archagent validate script --file ./scripts/my-script.agentscript

Fix any validation errors before deploying.

Phase 6: Deploy

Creating or updating the workflow through the top-level workflow commands persists it directly:

archagent create workflow --id my-workflow --file ./workflows/my-workflow.json
archagent update workflow my-workflow --file ./workflows/my-workflow.json

If the top-level workflow commands are unavailable in the current binary, or if the user is working inside a broader config-managed repo and explicitly wants that flow, route to manage-configs instead. Do not claim the dedicated workflow commands are available unless you verified them in the running CLI.

Phase 7: Attach to a routine

Workflows run via agent routines. Create or update a routine to use the workflow:

For a scheduled routine (cron):

archagent create agentroutine --agent <agent-id> \
  --name "Daily report" \
  --event-type schedule.cron \
  --schedule "0 9 * * 1-5" \
  --handler-type workflow_graph \
  --config-id <workflow-config-id>

For a webhook-triggered routine:

archagent create agentroutine --agent <agent-id> \
  --name "Inbound webhook handler" \
  --event-type webhook.inbound \
  --handler-type workflow_graph \
  --config-id <workflow-config-id>

To update an existing routine to use a workflow:

archagent update agentroutine <routine-id> \
  --handler-type workflow_graph \
  --config-id <workflow-config-id>

Phase 8: Test and monitor

Check routine runs:

archagent list agentroutineruns --routine <routine-id>

Use println() in scripts for debugging output.

User wants to edit an existing workflow

1. Inspect the current workflow:

   archagent list workflows
   archagent describe workflow <id>
   

2. Edit locally, then validate and update:

   archagent validate workflow --file ./workflows/my-workflow.json
   archagent update workflow <id> --file ./workflows/my-workflow.json
   

   The workflow resource versions on update; the agent picks up the linked workflow config on the next run.

User wants to set up a simple scheduled routine (no workflow)

Not everything needs a full workflow graph. For simple scheduled tasks, a routine can use a script directly.

Reference a script resource (preferred for production):

archagent create script --id daily-check --file ./scripts/daily-check.agentscript
archagent create agentroutine --agent <agent-id> \
  --name "Daily check" \
  --event-type schedule.cron \
  --schedule "0 9 * * 1-5" \
  --handler-type script \
  --config-id <script-config-id>

Get the config ID from archagent describe script daily-check --output json (the configId field).

Or inline for quick prototyping:

archagent create agentroutine --agent <agent-id> \
  --name "Daily check" \
  --event-type schedule.cron \
  --schedule "0 9 * * 1-5" \
  --handler-type script \
  --script 'println("hello")'

Or include the routine in the AgentTemplate:

routines:
  - name: daily-check
    event_type: schedule.cron
    schedule: "0 9 * * 1-5"
    handler_type: script
    config_ref: daily-check-script

Important: Scheduled routines need both schedule and event_type: schedule.cron. Do not put schedules under nested event_config.schedule.

Workflow Design Best Practices

• Start simple: Begin with a linear flow, add branching only when needed.
• Name nodes clearly: Use descriptive IDs (fetch_orders, check_status) not generic ones (step1, step2).
• Handle errors: Follow the real graph schema from workflowdocs and the sample config. Don't assume every HTTP call succeeds.
• Use scripts for logic: Keep business logic in Script resources or embedded workflow script data instead of improvising unsupported fields.
• Test scripts independently: Use archagent run script --file <path> to test scripts before wiring them into a workflow.
• Cron syntax: Standard 5-field cron. Use https://crontab.guru for help.

Recovery Rules

• If workflow validation fails, show the exact error — it usually points to a specific node or field.
• If a routine run fails, check archagent list agentroutineruns for the error details.
• If a workflow depends on script logic that does not exist yet, create and validate that script first.
• If the user is unsure about workflow vs. simple routine, ask how many steps the process has. One step = simple routine. Multiple steps with branching = workflow.

Response Rules

• Do not inspect or edit credential files directly — use the CLI only.
• Do not ask the user to pick raw subcommands when intent is clear.
• Keep responses concise and operational.
• When authoring workflows, show the user a concrete JSON graph draft they can review.
• Prefer showing the full workflow structure over explaining node types abstractly.
