A short user request can trigger several searches, model calls and connected actions. An agency's build quote does not describe that ongoing consumption. Before opening an assistant to staff or public visitors, define which resources are limited, how usage is attributed and what happens when a limit is reached.

SECTION 01
Ask where the limits are enforced
List the cost-producing operations: document pages, retrieval, generated tokens, external tools and background jobs. Define user or account quotas separately from overall project limits. Include anonymous traffic and automation that runs without a person present. A limit implemented only in the browser can be bypassed by direct requests.
OWASP's unbounded-consumption guidance covers excessive inference and resource use. Translate that risk into a practical brief: maximum input, bounded execution time and a finite number of tool steps. Avoid publishing invented provider prices; obtain current rates during solution selection and keep the usage model editable.
SECTION 02
Illustrative example: an internal research assistant
Suppose an employee asks an assistant to summarize every document in a large folder. The normal task was designed for a handful of selected files. Instead of silently launching a large job, the interface estimates the scope, asks the user to narrow it or routes it to an approved batch process.
If a tool repeatedly returns incomplete results, the assistant stops after its allowed attempts and explains the unresolved portion. The owner sees which workflow consumed the budget without needing complete private prompts in the usage dashboard. This example demonstrates operational boundaries rather than promising a particular monthly saving.
SECTION 03
Test fair failure and useful ownership
Test a large upload, rapid repeated submissions, several concurrent users and a model-tool loop. Verify limits across workers and resumed sessions, not just one browser tab. Distinguish a temporary rate restriction from an exhausted project budget so users know whether to wait, reduce scope or contact an administrator.
Microsoft's circuit-breaker guidance is useful where a failing dependency would otherwise attract repeated work. Handoff should include limit settings, alert recipients, override permissions and an explanation of which external costs remain outside application control. Tighter caps protect resources but may block legitimate long tasks; agree an explicit approved path for those exceptions.
SECTION 04
Frequently asked questions
Does a monthly budget alert stop spending?
Not necessarily. Verify the provider's behavior and implement application-side controls where needed. Describe any delay or costs outside those controls.
Can public visitors have the same limits as staff?
They may need different limits and permissions. Base the decision on expected tasks, abuse exposure and the information available for identifying users.
Should the app show exact cost before every request?
Only if it can estimate it responsibly. A bounded usage estimate or clear task limit can be more honest than a false exact price.
