Computer use agent consulting builds production GUI-operating agents for software that has no usable API: a perception–action loop over DOM, accessibility tree, or screenshot, running in a disposable sandbox, with confirmation gates on irreversible clicks and evals scored on task success. It is the wrong default whenever an API exists. A standard engagement is four weeks in your perimeter, and you own the loop, traces, and eval suite.
Why teams pick this engagement
AI Agent × EnterpriseAPI or MCP before pixels
Computer use is the leftover pattern. If a stable API, database, or MCP tool can do the job, we build that instead — it is faster, easier to permission, and cheaper to evaluate.
Sandbox with no production keys
The executor runs in a disposable browser or VM, domain-allowlisted, with no unconstrained network. The agent will click whatever it hallucinates; the sandbox is why that is not an incident.
Confirm on submit, pay, send, delete
Reversible navigation can auto-continue. Irreversible UI actions pause for a human or a policy check. Shadow mode then write access still applies to the UI loop.
Score task success, not pretty traces
Evals check whether the goal was met, the unsafe-action rate, and recovery from injected UI changes — not whether the trajectory looked reasonable.
Human fallback is a gate, not a hope
Loop detection, step budgets, and an escalate action are part of the schema. A stuck GUI agent does not keep clicking until something gives.
You own the loop and the traces
Perception–action traces, eval set, sandbox image, and runbooks are yours. Work stays in your perimeter. Model-agnostic. No token markup.
Key takeaways
- 01
Prefer an API, database, or MCP tool over computer use. UI agents exist for vendor portals, legacy thick clients, and internal apps that will not get APIs this year.
- 02
The executor runs in a disposable sandbox with no production credentials and no unconstrained network — the agent will click whatever it hallucinates.
- 03
Irreversible UI actions (submit, pay, send, delete) pause for a human. Reversible navigation does not need a person on every click.
- 04
Evaluate task success, unsafe-action rate, and recovery — not whether the screenshot trail “looks reasonable.”
- 05
Shadow mode then write access: the loop proposes clicks on live tasks before it is allowed to submit. You own traces, evals, and the sandbox image.
What the engagement covers
How we work
- 01
Discover
Week one: is there an API? If not, leftover surfaces, success checks, and risk.
- 02
Design
Sandbox, action schema, domain allow-list, confirmation gates, eval plan.
- 03
Build
Perception–action loop in your perimeter with weekly task demos.
- 04
Validate
Shadow mode on live tasks; submits stay off until evals hold.
- 05
Enable
Handover of loop, traces, evals, and runbooks; 30 days on-call.
