Returns regime, fear/greed, risk score, BTC price, and TVL from that date.' indicate pure data retrieval with no side effects." ## Use case AI agents call get_historical_context to retrieve information from Fathom Fyi 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**.
