It performs no write, execute, destructive, or financial operations. The blast radius of misuse is minimal — an agent could retrieve unwanted legislative information but cannot modify records, execute code, or cause financial harm. From the tool's own definition: "Tool description states 'List the cosponsors' and 'mapping coalitions behind legislation' — purely informational retrieval of public legislative data with no modification, deletion, or side effects." ## Use case AI agents call congress_bill_cosponsors to retrieve information from Livedatalink without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere. ## Recommended policy (PolicyLayer) Verdict: **Allowed**.
