Busywork, gone.
Pipelines that run themselves.

Deterministic workflows that fire on a trigger, branch on real conditions, retry on failure, and pause for a human only when it matters — with Claude wired in for the fuzzy steps. Built idempotent, monitored, and shipped to production, not a fragile no-code toy.

02 — Outcomes

Work that did itself.

A ledger of named workflows where the line that moved was a process that stopped needing a person — hours reclaimed, errors removed, handoffs that no longer drop. 6 of 28 shown · ledger updates as pipelines scale.

Northwind Finance
Invoice processing · AP automation
Inbound invoices parsed, matched to POs, and posted to the ledger — Claude reads the unstructured ones, the workflow handles the rest with idempotent retries
−31h/wkManual entry
Cobalt Sales
Lead routing · CRM orchestration
Every inbound lead scored, enriched, and routed to the right rep in seconds, with a Slack ping and a fallback queue when no owner matches
−94%Routing delay
Vera Health
Report generation · Scheduled
Nightly compliance reports assembled from four systems, drafted by Claude, and held at a human approval gate before they ever leave the building
−27h/wkReport prep
Lumen Ops
Onboarding · Provisioning
New-hire onboarding fans out across accounts, devices, and access groups from one trigger — each step idempotent, the whole run replayable on failure
3.4×Faster setup

Ticket triage · Intake automation
Inbound tickets classified, tagged, and routed with a cheap Claude Haiku step, escalating the genuinely ambiguous ones to a person instead of guessing

03 — The workflow, live

A process is a graph,
not a person.

Watch an event flow through the pipeline: a trigger fires, steps run in order, a branch evaluates a real condition, an action commits. Push the volume up, toggle a step off, or inject a failure and watch the retry fall through to a fallback — exactly how a deterministic workflow earns its uptime.

Throughput
Deterministic orchestration handles the predictable path — validate, branch, commit, retry. The one fuzzy step (read a messy invoice) is the only place an LLM belongs. That's the line between a workflow and an agent.
04 — The workflow inventory

Every pipeline,
named and watched.

Automation isn't one magic flow — it's a fleet of small, observable workflows, each with a trigger, a chain of steps, the tools it touches, and a status you can actually see. This is the console we run them from.

05 — Ship to production

Map the process.

Before a single node is wired, we sit with the people doing the work and trace the real path — every step, every exception, every "well, usually." Then we mark what's deterministic and what's genuinely fuzzy. The map is the spec.

/ Week 00 · Map & scope
TriggerWhat kicks it off — a webhook, a schedule, a row change, an email landing
StepsThe happy path, written down — each step with one clear job and one output
ExceptionsThe "what if" branches that quietly eat hours — mapped, not ignored
FuzzyThe one or two steps that need judgement — flagged for an LLM, nothing more

Wire the graph.

Build the workflow as a graph of typed steps — trigger, transforms, branches, actions. Each node does one thing, takes structured input, returns structured output. No 400-line script; a pipeline you can read at a glance and change without fear.

/ Week 01 · Build
TriggerWebhook · cron · queue · file-watch · email
StepsTyped nodes · one job each · structured I/O
BranchConditionals on real data · true / false paths
LLM stepClaude Haiku for the fuzzy parse — and only there
ActionCommit to the system of record · emit events

Make it idempotent.

The difference between a demo and production is what happens on the second run. Every step gets an idempotency key, retries are safe to repeat, and a re-fired webhook never double-posts. Run it twice, run it ten times — the result is the same.

/ Week 02 · Harden
Idempotency keys on every side-effecting step
Exponential-backoff retries with a cap
Dead-letter queue for the ones that still fail
Exactly-once posting to the system of record
Replay a failed run from any step, safely

Gate the irreversible.

Most steps should just run. A few — paying money, emailing customers, deleting records — pause for a human. We put approval gates exactly where the cost of being wrong is high, and nowhere else, so the workflow stays fast where it can be.

/ Week 03 · Approvals

Watch everything.

Every run is logged, traced, and counted. We watch success rate, retry rate, and latency per step, and we alert before a queue backs up — not after a customer notices. A workflow you can't see is a workflow you can't trust.

/ Week 04 · Observe
Success rate99.7% — runs that completed without intervention
Retry rate1.4% — recovered on backoff, never lost
p95 latency0.4s — per step, trigger to commit
Cost / run$0.004 — Haiku on the one fuzzy step

Ship & tend.

Live with versioned workflows, safe rollbacks, and a changelog on every node. As the business shifts, the graph shifts with it — new branches, new tools, new triggers — without a rewrite. Automation that ages well, not a flow that rots.

06 — Why it compounds

A tended pipeline keeps paying.

Each workflow you ship frees the hours to ship the next. Reliability compounds too — every fixed edge case, every tuned retry makes the whole fleet steadier. Bolt-on no-code zaps drift the moment an API changes; a versioned, monitored system holds and grows.
