Finds the overrun while it is still four weeks away
Projects fail financially in a predictable way. The cost report says 60% spent and 60% complete and everything looks fine — because "60% complete" was estimated by the person whose performance the number reflects. Percentage complete is the softest figure in project management, and every cost report is built on it.
The hard signals are available much earlier. Committed cost — what has been ordered, not what has been invoiced — is money the project cannot get back, and it routinely exceeds budget while the spend report still looks healthy. Variations instructed but not yet priced are a liability the cost report does not contain at all. Rates that drifted from the tender. Preliminaries burning at a fixed weekly rate against a programme that has slipped, which is the purest form of cost with nothing to show for it.
And the cost report and the programme are separate documents owned by different people. A four-week delay is a programme fact and a cost fact, and nobody joins them until the final account.
This agent joins them. It reports forecast cost at completion from committed and unpriced exposure rather than from spend to date, names which package is driving the variance, and says which findings rest on a firm figure and which on an estimate. It approves nothing and instructs nothing.
Rather than confirmed at the final account.
So the intervention is specific rather than a blanket freeze.
With its soft figures marked as soft.
What has been ordered is money the project cannot get back. It exceeds budget while the spend report still looks healthy.
Instructed and unpriced is a liability the cost report does not contain at all.
A four-week slip is a cost fact. Two documents, two owners, joined at the final account and never before.
A fixed weekly cost against a slipped programme — spending with nothing produced for it.
Each instance small, the cumulative effect not.
A forecast built on estimates should say so on every line. Most do not.
Why Construction in particular. Cost reports are built on percentage complete — the softest number in project management, estimated by the person it reflects. Committed cost routinely passes budget while spend to date still looks healthy.
Runs unattended
Started by you or by an event, and it finishes on its own. Nothing waits for someone to be at a desk.
The same standard every time
The two-hundredth item is held to the bar the first one was. Consistency is the part people cannot sustain.
It cannot act on its own
Project Cost Variance Agent has no path to sending, spending or committing. That limit is why its output is safe to act on.
This agent runs server-side through the PROMIVO runtime. Each run is logged step by step and every tool call is permission-checked before it executes.
Read-only by design. This agent has no path to sending, spending, publishing or committing anything. Where that limit is the product, removing it would remove the reason to trust the output.

No. It reads the same documents faster and joins the cost report to the programme, which nobody has time to do monthly. Every judgement — whether a variation is recoverable, whether a delay is your risk — stays with them.
No. It reports that a variation is instructed and unpriced, and its estimated exposure where the record supports one. Pricing a variation is a commercial and contractual judgement.
Never. It has no route to a client, a contractor or a contract administrator, and entitlement is a legal question about a specific form of contract.
