I Ran 4,200 Trials Testing LLM Agent Reliability. Here’s What Broke.

We know when an AI agent gets a response from a tool, getting a response back doesn’t necessarily mean that response should be trusted.

  • I conducted 4,200 trials to test LLM agent reliability.
  • ReliAgent identified signals for cautious response treatment.
  • Distinction between model behavior and detector failure crucial.

Why your AI coding agent should never see your API keys

Your AI coding agent needs your API keys. It needs them to call services, to test integrations, to run your stack. So you give it .env files, or you export keys into the environment, or you paste them…

  • API keys must remain secure when using AI coding agents
  • Developers often expose keys via .env files or environment exports
  • AI agents can leak secrets through context, output echo, and prompt injection
