WHAT IT DOES

What hooks does on OpenClaw

AI agents use hooks to create or update resources in OpenClaw, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your OpenClaw environment.

RISK

Why hooks is rated Medium

The word 'manage' typically encompasses creating, updating, and potentially deleting hooks. Since the description is vague and doesn't specify read-only access, the most likely interpretation is that this tool can write/modify hook configurations. However, if hooks can be deleted, it could edge toward Destructive. Without more detail, Write is the best fit. Confidence is moderate due to the uninformative description.

From the tool's definition "Manage internal agent hooks" — 'manage' implies create/update/delete operations on hook configurations

RECOMMENDED RULE

The rule that runs hooks safely

PolicyLayer is an MCP gateway: it sits between your AI agents and OpenClaw, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For hooks, this is the rule to start with:

hooks Rate-limited

hooks stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

          "max": 30,

The button opens the PolicyLayer dashboard: create your workspace, connect OpenClaw, apply this rule, and every hooks call is checked against it from then on.
