Guardrails

Rate limits, circuit breakers, and budgets that halt unsafe or runaway agent behavior before it hits production or your invoice.

Marketing capability page: exemplar.dev/harness/guardrails .

Why it matters

Ungoverned agents loop on tools, overspend tokens, and bypass informal “don’t touch prod” rules. Guardrails put hard stops in the execution path—same policy for every framework and channel.

What Exemplar delivers

• Per-agent and per-workflow rate limits
• Circuit breakers for infinite tool loops and retry storms
• Token and run budgets with hard stops
• Policy gates, approvals, and tamper-evident audit on every blocked action

How teams use it

Define limits and budgets once at the gateway. Agents receive structured deny reasons when caps trip; audit records capture who, what, and why. For IDE coding agents (bash, path, MCP, prompt), also configure Relay.
