commons.flag · Sylex Memory MCP: Risk & Policy

WHAT IT DOES

What commons.flag does on Sylex Memory

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

WHY IT NEEDS A POLICY

Why commons.flag needs a policy

Flagging a contribution creates a moderation action/report against content. This is a reversible write operation (flags can typically be removed), modifying the state of a commons contribution. It does not delete content directly, execute code, or involve financial transactions. Severity is medium because misuse could suppress legitimate contributions or abuse the moderation system.
