Builtin Plugins

AgentGuard includes built-in plugins for common runtime protection needs. This page groups the built-in plugins currently documented in this manual by where they run.

Built-in Client Plugins

• jailbreak_check: an llm_before prompt-injection detector that can run locally inside the agent process and block suspicious prompts before they reach the model.

Built-in Server Plugins

• rule_based_plugin: a server-only rule engine for tool-call access control and policy evaluation that can either return fixed ALLOW / DENY decisions or escalate matched cases to HUMAN_CHECK / LLM_CHECK.
• jailbreak_check: the same LLM-input detector can also run on the AgentGuard server when you want centralized governance and auditing.
• Thought-Aligner: an opt-in llm_after intervention that rewrites exposed reasoning on the server and makes a compatible Python client regenerate its action before execution.

Other utility plugins also exist in the codebase, but this page focuses on the built-in plugins that are documented for direct use in the public docs.
