WHAT IT DOES

What genlayer_deploy does on Genlayer Cli

AI agents invoke genlayer_deploy to trigger actions in Genlayer Cli. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why genlayer_deploy needs a policy

Deployment of smart contracts is an Execute operation because it triggers irreversible external operations (blockchain state changes, contract instantiation, fund transfers). While deployment effects depend on contract code (which could be destructive), the tool itself performs the deployment action without deletion.

From the tool's definition Tool performs 'Deploy a GenLayer Intelligent Contract' which triggers external deployment operations. Description explicitly states it 'Accepts privateKey; generates one when missing or invalid', indicating it executes blockchain/smart contract deployment…

genlayer_deploy Rate-limited

genlayer_deploy stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

What risk level is genlayer_deploy? +

genlayer_deploy is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit genlayer_deploy? +

Yes. Add a rate_limit block to the genlayer_deploy 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.
