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.

Execution Failure Containment

How unexpected autonomous errors, injection payloads, and runaway cycles are intercepted in live production.

SQL & Data Mutations

Critical

Without Exogram:

Cohere relies on natural language alignment or connection permissions. Unsanitized mutations execute against target databases.

With Exogram:

Intercepts the SQL AST in 0.07ms, enforcing strict read-only constraints and table mutation barriers.

Pre-execution SQL AST validation

Rogue API & Retry Loops

High

Without Exogram:

Agents can enter cyclical retry states upon receiving error responses, firing thousands of unauthorized tool calls.

With Exogram:

Tracks state transitions across turns, halting infinite loops and duplicate mutations on turn 2.

Cryptographic state tracking & circuit breakers

Memory Drift & Poisoning

High

Without Exogram:

Context windows accumulate hallucinations and conflicting state over long-horizon sessions.

With Exogram:

Maintains SHA-256 state hashing across all memory writes, verifying facts before persistence.

SHA-256 state hashing & dual-write sync

Latency & Compute Footprint

Deterministic CPU execution eliminates secondary LLM inference delays and API billing.

Cohere Overhead

Sub-second to multi-second

Dependent on secondary model API hops, token generation, or cloud roundtrips.

Exogram In-Memory Gate

0.07 ms

Compiled deterministic bitmask logic gates running on standard host CPU.

Exogram evaluates actions inside your application process in 0.07ms with zero network hops and zero recurring token costs.

Failure Trajectory Analysis

Un-Gated Action Execution vs. Governed Autonomy Interception

Target Actor:Autonomous Agent with Cohere Tools

Initial Trigger:Automated user prompt triggers high-privilege tool call in production

Without Exogram Protection

1.Agent loop generates tool call payload and invokes production system directly without pre-execution validation.

2.Probabilistic reasoning drifts on an ambiguous edge-case input or schema variance.

3.Un-gated mutation writes inconsistent or unauthorized state directly to production databases.

4.Cascade failures propagate downstream, creating silent data corruption and customer-facing downtime.

With Exogram Interception

1.Agent submits intended tool call and execution payload to Exogram Authority Runtime.

2.Exogram evaluates policy constraints inside the application process in 0.07ms (zero network hops, zero token cost).

3.Deterministic boundary intercepts unauthorized mutation before execution, halting the loop with code ERR_MUTATION_UNAUTHORIZED.

4.Immutable SHA-256 state hash receipt is signed and recorded to append-only ledger; production state remains pristine.

Business Impact Avoided:Prevented un-gated production state corruption and catastrophic recovery rollback.

STEP 3Deterministic boundary intercepts unauthorized mutation before execution, halting the loop with code ERR_MUTATION_UNAUTHORIZED.

RESULT: Prevented un-gated production state corruption and catastrophic recovery rollback.

The Plain English Verdict

Use Cohere for retrieval. Use Exogram to govern what agents do with what they find. Good context ≠ safe actions.

The Negative-Carry Code Crisis in AI Software

Accepting AI-generated code and un-gated tool executions into production without deterministic architectural verification creates compounding technical debt analogous to negative-carry financial assets.

What Cohere Does

•Cohere provides enterprise-grade models for search (Embed, Rerank) and generation (Command R+).
•Strong RAG capabilities with optimized retrieval pipelines.
•No execution governance — agents can act on retrieved context without validation.

What Exogram Does

Exogram governs actions that agents take based on Cohere-retrieved context.
RAG systems surface the right information. Exogram ensures agents don't misuse it.
Search accuracy doesn't prevent destructive actions — a correctly retrieved fact can still lead to a harmful tool call.

Frequently Asked Questions

Does Exogram compete with Cohere Embed or Rerank?

No. Exogram actually uses vector search (via Pinecone) internally. Cohere and Exogram operate at different layers — retrieval vs. governance.
