WHAT IT DOES

What store_conversation_checkpoint does on Session Buddy

AI agents use store_conversation_checkpoint to create or update resources in Session Buddy — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Session Buddy environment.

WHY IT NEEDS A POLICY

Why store_conversation_checkpoint needs a policy

This tool writes/creates a checkpoint record of conversation state. It is a reversible write operation (storing data), not destructive, not executing code, and not financial. Severity is medium because an AI agent could misuse it to store false or misleading session data, potentially corrupting session history or memory used in semantic search across coding sessions.

From the tool's definition 'Store a conversation checkpoint from current session context' — stores/creates data (checkpoint) associated with the current session

Verdict

store_conversation_checkpoint Rate-limited

store_conversation_checkpoint stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
