Research → Design → Outreach → Evidence

A design practice with an agent behind it.

I built a tool-using Codex workflow that finds promising independent venues, researches a real website problem, creates a private visual direction and handles outreach through strict safety gates.

01 / Orchestration

One agent. Explicit handoffs. Observable decisions.

From a place to a decision.

The model handles research, judgement and visual direction. Deterministic controls decide whether a candidate can advance. The same workflow checks replies first, then works down qualified sends and design production.

01 / Discover

Find the real business.

Independent venues with current activity, strong presentation and a plausible reason to invest.

02 / Qualify

Prove the need.

Operator, public contact, mobile journey and a concrete commercial problem are checked before creative work.

03 / Design

Make it specific.

A private, source-backed responsive concept uses the venue’s own published character and content.

04 / Control

Guard the send.

Country rules, suppression, local time, caps, MIME integrity and idempotent claims gate Gmail.

05 / Respond

Keep the thread human.

Ordinary interest continues; opt-outs close; final commercial commitments go to Wade.

The important boundary
The live operation is a scheduled Codex agent with one authorized Gmail writer. This portfolio case shows a separate, credential-free replay of its deterministic controls. No public visitor can send outreach from this site.

02 / Failure-aware engineering

Inspectable by design

The happy path is the easy part.

I built an offline evaluation harness around the same inventory, send-window, suppression, reply-routing and SendJournal controls. Each fixture supplies a pre-reviewed judgement; the replay tests what the system does next. It makes failure behavior visible without contacting a real business.

04 / What this proves

A project you can inspect, and a boundary you can trust.

Built to show the work.

The live workflow has made real outreach sends and developed venue-specific private concepts. This project’s offline suite proves the guard behavior shown above; the portfolio proves complete responsive design and development. Neither a synthetic accepted outcome nor a Gmail SENT record proves inbox delivery, a buying signal or a paying client.

The next commercial milestone is an independently verified positive conversation that moves through scope, price and delivery. Until then, I describe the Agent as a working, guarded outreach and design system, not an autonomous customer-acquisition success.
