RISK

Why prepare_tron_claim_rewards is rated Critical

This tool builds and prepares a financial transaction on the TRON blockchain that claims accumulated staking/voting rewards. While it only builds an unsigned transaction (the actual signing and broadcast happen via `send_transaction`), it directly initiates a financial operation involving crypto asset movement.

From the tool's definition 'claims accumulated voting rewards to the owner's balance' and 'forward via `send_transaction` for USB-HID signing' — initiates a TRON blockchain transaction that moves crypto assets (rewards) into an account
