Agent type

Workflow Orchestrator Agent

Cross-SaaS triggers — Microsoft 365, Slack, Sheets, HubSpot, Stripe — with idempotency and approvals

What an orchestrator actually does

You have a SaaS stack with maybe 15 tools. Events happen in those tools — deals close, leads arrive, payments fail, calendar bookings made, tickets opened, stock changes hands. Right now humans see those events and take a sequence of actions in other tools. We replace that "humans see and act" step with an orchestrator that watches for events and runs the corresponding workflow.

A typical orchestrator workflow:

[New lead in HubSpot]
      ↓
[Enrich via Clearbit + LinkedIn + custom rules] (parallel)
      ↓
[Score: hot/warm/cold based on rules + LLM judgment of message]
      ↓
[Conditional routing:
   ├─ hot → Slack alert to AE → calendar invite next day
   ├─ warm → drip campaign in HubSpot
   └─ cold → archive with reason]
      ↓
[Log to lead-lifecycle dashboard]

Each box is observable. Each transition is logged. Each external action is idempotent. Anything irreversible has an approval gate.

Why orchestrators are different from "Zapier"

Zapier and Make and Power Automate's low-code modes are fine for many workflows. They become painful at scale for predictable reasons:

ProblemLow-code defaultOrchestrator default
Duplicate runsSometimes (retries, webhook redelivery)Idempotency keys on every action
Transient upstream failuresManual replay from the dashboardAuto-retry with exponential backoff + jitter
Permanent failuresDies silently in a queue you don't watchDead-letter queue with structured reason + alert
Schema drift upstreamWorkflow breaks; nobody knowsSchema validation at boundary; fails loudly
Branching logicUI gets unwieldy past ~5 conditionsState machine in code
Cost per run at scalePer-task fees add up fastCustom code; near-zero marginal cost
Audit / replayLimited (most low-code tools have 30–90 day history)Full per-run trace, queryable, indefinite
LLM judgmentBolted on awkwardlyFirst-class with eval coverage

We use Power Automate / n8n where the trade-offs make sense — fast time-to-value, Microsoft tenant governance, low operational overhead. We use custom code when reliability or volume tips the balance.

When LLM judgment belongs in a workflow

Most orchestrator workflows are 90% deterministic rules with 1–3 LLM-judgment steps. Examples of judgment steps:

  • Classification. "Is this email a quote request, a support issue, or a complaint?"
  • Extraction. "Pull the project budget from this RFP email."
  • Routing. "Which AE should this lead go to based on the territory and the message content?"
  • Summarization. "Generate a one-line summary for the CRM custom field from this support ticket."
  • Verification. "Does this customer's claim match the order history we have on file?"

LLM judgment steps need evals like any other LLM use. We build them in.

Production patterns we always include

Idempotency keys

Every action gets a key. Re-running the workflow with the same trigger produces the same outcome, never duplicates the action.

Retry with exponential backoff and jitter

Transient failures self-heal. Stampedes are avoided by jitter.

Dead-letter queue

Permanent failures land here with full context — original event, intermediate state, error message, retry count. Humans replay or annotate from a one-page dashboard.

Approval gates on irreversible actions

Anything that moves money, sends a customer-visible communication beyond templates, signs a contract, or provisions an account pauses in a Slack-approval state. The agent does the work; humans approve.

Circuit breaker per integration

When an upstream is detected as degraded, the orchestrator pauses calls to it and queues events. When the upstream recovers, the queue drains.

Per-run trace

Every workflow run produces a structured trace — trigger event, each step's outcome, total duration, total cost. Queryable from a dashboard.

Where it pairs

Orchestrator agents commonly invoke:

  • Document processing agents when a workflow event involves a document (incoming invoice, contract, claim form).
  • Conversational agents when the orchestration step is "ask the user a clarifying question."
  • Research agents when a workflow needs enrichment (prospect research before assigning the lead).
  • Voice agents when the workflow needs to make or receive a call (appointment confirmation, follow-up).
