The Cross-App Workflow Cost $5.44. Here's How We Got It to $0.17.
A hybrid agent running browser research + desktop spreadsheet creation cost $5.44 baseline. Optimizing each leg independently — Playwright for the browser, CLI-first prompt for the computer use desktop leg — brought it to $0.17. The browser leg did most of the damage.

The Test Isn't Whether the Agent Picks the Right Tool. It's What Happens When the Tool Fails.
I built a hybrid agent expecting the routing to be the demo. The actual demo turned out to be what happened when a tool call failed and the outer model retried with a different approach — twice in two runs.

I Had a Working Agent at $3.41 a Run. Here's Where the Money Was Actually Going.
Same task, different harness configurations. Caching the inner loop saved 29%. Convergence rules saved 54%. Eliminating the LLM from the browser loop entirely dropped cost from $3.41 to $0.03. The harness is where the margin lives — and the harness goes all the way down.

API → Connector → Browser → Computer Use → Human: A Cost-Justified Hierarchy for Agent Tooling
Computer use is 45× more expensive than a structured API for the same task. Eight harness configurations across browser, desktop, and hybrid showed costs from $0.03 to $5.44 on the same task — the hierarchy, the numbers, and why implementation beats model choice.

Composer 2.5 Earned a Daily-Driver Slot — After Two Days of Real Wiring Work
First impressions of Cursor Composer 2.5 in the agents UI: integration work across repos, 328 requests and ~202M tokens on the included pool, 95%+ cache hits — not a review, a usage report.

When the Tool Doesn't Know About the Vault
op run wraps any process and resolves vault references as normal env vars — so the tool reads credentials without knowing 1Password exists.

The Same Pattern, From Solo Builder to Enterprise Scale
The credential pattern in this series works for one person today. It also works for a team of ten, or a company of ten thousand. The vault-and-IdP architecture doesn't change when you add users. That's the point.

1Password as the Trust Anchor for an Agent Auth Chain
The previous posts covered what 1Password stores. This one is about what it does — as the live trust anchor when an agent acquires tokens, enrolls MFA, and calls protected APIs without a human passing credentials by hand.
