Stack Boundary

Know what you own before any tool acts.

Your team should be able to see who owns the accounts, where secrets live, which actions can run, which decisions need approval, what stops, and what evidence travels with the handoff.

Your team keeps
Accounts, context, decisions

Business ownership, approval authority, source accounts, data rights, and final operating decisions.

I deliver
Maps, rules, evidence

Workflow maps, action contracts, control rules, release evidence, runbooks, and handoff notes.

Vendors provide
Replaceable infrastructure

Hosted services, APIs, uptime, product limits, and platform-specific capabilities.

How the stack becomes a service

The stack should read like a handoff, not a vendor diagram.

The story stays simple for a non-technical team: map the boundary, pilot one safe workflow, then control the risky actions only when live work needs it.

01 Map
Workflow Map

Name the workflow, source accounts, decision owner, first action boundary, and evidence needed before delegation.

02 Pilot
Workflow Pilot

Turn one repeated handoff into scoped actions, durable state, receipts, and a runbook only after the safe path is clear.

03 Control
Ongoing Control

Classify live actions as auto-allowed, approval-needed, or blocked with a reason before the workflow touches risk.

Boundary canvas

A stack boundary becomes useful when it shows what must stop.

The story canvas turns vendor roles into an operating map: source data, allowed routing, assistive work, human judgment, stop conditions, and the audit trail.

Stack boundary canvas

The workflow boundary decides what tools are allowed to do.

This read-only map shows the stack promise in workflow terms: tools can route and prepare, but payout, denial, fraud, and sensitive decisions stop for named authority.

1. Map Claim intake packet before execution. Claims operations owner owns the operating path. The canvas makes the workflow, handoffs, and next decision legible before an agent or system acts. 2. Claim system triage can run when the rule is clear. Claim system triage coordinates with Coverage context summary; the map keeps AI assistance bounded to the work it can safely support. 3. Adjuster review stays with a person. Adjuster handles coverage uncertainty, fraud flags, payout, denial, and sensitive messaging. 4. No payout or denial authority is the stop condition. Stop before coverage decision, payout, denial, or fraud escalation without authority. 5. Claims queue receipt shows the receipt. Shows triage class, missing documents, adjuster state, and customer-contact trail. 6. Use the map as booking context for a workflow pilot. The map has enough owner, assistive work, system behavior, and decision context for a first run.

What your team keeps

You keep the receipts, not a mystery stack.

The technical stack can change. The durable asset is the workflow boundary: source accounts, scoped access, allowed actions, stop states, approval owners, runbooks, revocation paths, and evidence.

Map
Workflow Map

One workflow, source systems, owners, handoffs, and failure points.

Boundary
Stack boundary

What your team owns, what CREATE SOMETHING owns, and what vendors provide.

Contract
Tool/API contract

Tools, resources, auth scopes, allowed actions, and transport limits.

Control
Policy rules

Auto-allow, approval-needed, and blocked states with reasons.

Operate
Runbook

Recovery, release evidence, rollback notes, and operator handoff.

Surface
Operator brief

The visible state for Webflow, Dify, Linear, Notion, or a custom app.

Vendor roles

Vendor names are receipts, not the explanation.

Each service earns a clear job. The connected tools are replaceable infrastructure; the proof is the map that shows what connects, what runs, what waits, what stops, who decides, and what the operator receives.

Runtime
Cloudflare

Workers, D1, Durable Objects, queues, and edge routes keep the workflow deployable while account ownership, billing, and rollback evidence stay explicit.

Connectivity
Composio

OAuth, connect links, and standard app actions stay commodity when the durable value is the scoped action boundary, not the connector.

Agent surface
Dify

Visible agent surfaces, repeatable server cards, and operator-facing automation when the workflow needs packaging with approval states attached.

Workspace
Notion

PM visibility, client-readable evidence, template distribution, and human review around agent work without treating Notion as the source of truth for everything.

Reasoning
OpenAI

Reasoning and agent hosting become useful when surrounded by scoped tools, approval behavior, evals, and traceable context instead of hidden authority.

Surface
Webflow

Sites, templates, apps, forms, dashboards, and marketplace-facing operator experiences become controlled interfaces with readable handoff evidence.

Ledger
Linear

Tracked work, ownership, status, validation, release notes, and unresolved decisions become the shared evidence ledger for the next operator.

Boundary
Infisical + Clerk

Secrets and identity stay out of prompts and handoff docs, with sign-in, token issuance, entitlement checks, and revocation separated before launch.

Start with the workflow

Bring the workflow, the accounts, and the decision owner.

CREATE SOMETHING will map the stack boundary, define the first controlled path, identify what can be assigned, and show what stays visible to the operator before implementation starts.

Workflow First workflow map

Objects, source systems, owners, handoffs, and failure points.

Boundary Vendor and ownership boundary

What your team owns, what I deliver, and what vendors provide.

Control Decision states

Auto-allow, approval-needed, and blocked states with reasons.
