Before You Expose That Agent, Let a Free Model Attack It

To secure tool-using language models, developers should use free model endpoints for red-teaming to identify prompt-injection and tool-abuse failures. To optimize CI jobs, implementing reproducible records of input envelopes and output hashes allows replaying specific model calls without restarting entire pipelines. Additionally, building a stateful token ledger helps manage free model tier allowances by tracking projected and actual usage. These strategies, supported by MonkeyCode's open-source project, ensure efficient validation and security before production deployment.
