AI agents use quote-a-tweet to create or update resources in X — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your X environment.
Quoting a tweet is a reversible write operation that publishes new content on Twitter/X. It creates a new post referencing the original tweet. It could be misused to amplify content at scale, but it is not irreversible (tweets can be deleted), not financial, and not arbitrary code execution. Severity is medium due to potential for reputational harm or spam if misused by an AI agent.
From the tool's definition "Quote a specific tweet" — creates a new tweet that quotes an existing one

quote-a-tweet is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the quote-a-tweet rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for quote-a-tweet. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
