Execution Limits and Boundaries

Time limits, retry caps, and resource boundaries prevent runaway tasks so you never face surprise costs.

AI tasks that run too long or loop without progress waste money. Execution limits prevent that. Set a maximum duration per task (for example, 10 minutes), a retry cap (for example, 3 attempts), and a resource ceiling per employee or company-wide. If a task hits any limit, it stops cleanly, saves its progress, and notifies you.

Limits are especially important for scheduled and autonomous work. A task running at 3 AM without supervision should not burn through your entire credit balance because it entered a loop. Execution limits ensure that even unattended work stays within the boundaries you set.

When a task stops at a limit, the notification includes what happened, how much was consumed, and a suggested next step. You can increase the limit for that specific task, adjust the employee's configuration, or investigate the issue. Limits are guardrails, not dead ends. They protect you while giving you full visibility into what went wrong.

Prevent Runaway Tasks With Hard Execution Boundaries

Autonomous agents are powerful precisely because they keep working without constant supervision. But that same quality can become a liability if a task enters an unexpected loop, hits a rate-limited API repeatedly, or spawns more subtasks than intended. Execution Limits give you hard ceilings so no single agent task can consume unbounded resources.

You can set time limits (maximum wall-clock time for a task), retry caps (maximum attempts before a tool call is abandoned), step counts (maximum number of agent actions per run), and resource ceilings (token usage, API call counts). When a limit is reached, the agent stops, logs what it was doing, and notifies you, rather than silently failing or running forever.

Configure Limits Per Employee and Per Task Type

A research agent that synthesizes long documents legitimately needs more steps and more time than a scheduling agent booking a meeting. Execution Limits are configurable per employee and per task category, so you can give complex agents room to work while keeping simpler agents tightly scoped.

Default limits are set at the workspace level and apply to all new employees at hire. Individual employees can have their limits adjusted up or down from the workspace default. This layered approach means you always have a safety floor, with flexibility on top for agents that genuinely need it.

When a limit is triggered, the full execution trace up to that point is preserved in the Execution Inspector. You can review exactly what the agent was doing, why it hit the limit, and decide whether to adjust the limit, fix the task configuration, or intervene manually.

Why Execution Limits Are Non-Negotiable for Production AI

In production environments, runaway agent tasks are not just expensive. They can trigger cascading failures in downstream systems, exhaust third-party API quotas, or produce thousands of unwanted side effects before anyone notices. Execution Limits are the circuit breaker that keeps isolated agent failures from becoming systemic problems.

This is especially important as you scale your AI workforce. With five agents, you can watch every task manually. With fifty, you cannot. Execution Limits let you operate at scale with confidence that no single agent or task can damage the whole system, even if something unexpected happens.

Use Cases

Ops team caps AI agent runtime on expensive workflows

Execution limits stop a runaway AI agent after a set time or step count, preventing a loop from consuming credits and causing delays.

Finance team sets monthly AI usage budgets

Execution limits enforce a per-agent or per-team cap on total usage, so AI spend never exceeds what was budgeted.

Developer team prevents infinite loops in agent pipelines

Step and recursion limits catch agent loops early, terminating the run cleanly and sending an alert instead of burning through resources.

Enterprise team enforces fair-use across departments

Execution limits ensure no single team or AI employee monopolizes platform resources, keeping performance consistent for everyone.

FAQ

What happens when an agent hits an execution limit?

The agent stops immediately, logs the limit event with full context, and sends a notification to the employee's owner or the workspace admin depending on your alert settings. The incomplete task is preserved in the activity feed for review.

Can I set different limits for different tools?

Yes. You can apply per-tool retry caps and call-count limits in addition to per-employee global limits. For example, you might allow an agent unlimited internal reasoning steps but cap external HTTP calls at 20 per task.

Do limits apply to multi-agent workflows?

Limits apply per agent. In a multi-agent chain, each agent in the workflow has its own limits. This prevents a single misbehaving agent from consuming the resources allocated to the entire pipeline.

What is a reasonable default limit for most tasks?

For most business tasks, 50 steps and a 10-minute wall-clock limit cover the vast majority of real work while catching loops early. We recommend starting with these defaults and adjusting based on actual task logs rather than setting high limits preemptively.

Can I set limits on how long or how many times my AI agent retries a task?

Yes, execution limits let you cap run time, set retry counts, and define resource usage thresholds per task or per employee. If a limit is hit, the agent stops cleanly and logs what happened.

Before execution limits, we had agents occasionally run for twenty minutes on a stuck tool call. Now they cap at three minutes and escalate. Our costs dropped immediately.
