How to prevent an AI agent from executing an infinite loop?

Exogram acts as an Execution Authority Layer that monitors intent and rate limits tool calls, intercepting unmonitored loop cost overruns before they execute.

How do you stop LLM indirect prompt injection API access?

A Semantic Firewall decouples the LLM's non-deterministic text generation from the actual tool execution. Exogram inspects the intent of the payload, blocking unauthorized state mutations triggered by prompt injection.

What are deterministic guardrails for LLM tool calls?

Deterministic guardrails are strict, code-level policies (like capability downgrading) that cannot be bypassed by natural language. Exogram wraps every tool call in these policies to prevent execution drift.

Why do AI agents retry so aggressively when an API fails?

Most agent frameworks (like LangChain or AutoGen) are designed with self-healing loops. If an output doesn't match expected JSON or returns an HTTP error, the framework automatically asks the LLM to fix the error and try again, creating an infinite spending loop.

How does Exogram detect a loop before it burns my wallet?

Exogram tracks call counts, payload hashes, and execution velocity in a local SQLite ledger. If an agent calls the same tool repeatedly with similar payloads, Exogram trips the circuit breaker instantly.

Will Exogram slow down my agent while checking for loops?

No. Exogram checks the counter locally in 0.07 milliseconds before the network request is initiated. There is zero perceptible lag.

Why can't I just use read-only Postgres user permissions?

Read-only database permissions work for pure analytics bots, but fail as soon as an agent needs legitimate write access (like inserting new leads or updating statuses). Exogram lets you grant write permissions while strictly forbidding destructive DDL statements.

Does Exogram use an LLM to check if the SQL is safe?

No. Using an LLM to review SQL adds 500ms of lag and can be tricked by obfuscated SQL. Exogram uses deterministic AST parsing in 0.07ms without making any third-party API calls.

What error does the AI receive when a dangerous query is blocked?

The AI receives a clean error message stating that the action violates database invariant policy. The agent can then adjust its query to a non-destructive alternative without crashing.

Can a customer trick the AI into giving multiple small $25 refunds?

No. Exogram tracks cumulative spend per customer ID and per session over rolling 24-hour windows. If the bot attempts three $25 refunds for the same user, the velocity check triggers and locks the tool.

What happens when a refund is blocked?

The action is placed in an audit queue, and the customer is told: "A refund of this size requires manager confirmation. Our support lead will review this within 15 minutes."

The AI Breakage & Emergency Room

What did your AI bot
just break?

Language models don't break your database or rack up $3,000 bills out of malice. They do it because they're trying to be helpful and have no physical brakes. Here is what actually went wrong—and how to lock it down in under five minutes.
