Reset a WASM agent — clears messages and turn count so it can be reused across tasks. Use when native Task is wrong because the agent lives in a sandboxed WASM runtime that must be explicitly reset rather than simply re-spawned.
AI agents call wasm_agent_reset to permanently remove resources in Claude Flow — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool irreversibly clears the agent's message history and turn count. While it doesn't delete persistent external data, the in-flight conversation state and task context are permanently destroyed and cannot be recovered. This is a destructive operation on the agent's runtime state.
From the tool's definition 'Reset a WASM agent — clears messages and turn count' — explicitly clears/destroys existing state (messages, turn count) irreversibly
Attacks that exploit this kind of access
Reset a WASM agent — clears messages and turn count so it can be reused across tasks. Use when native Task is wrong because the agent lives in a sandboxed WASM runtime that must be explicitly reset rather than simply re-spawned. It is categorised as a Destructive tool in the Claude Flow MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Claude Flow MCP server in PolicyLayer and add a rule for wasm_agent_reset: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Claude Flow. Nothing to install.
wasm_agent_reset is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the wasm_agent_reset 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.
Set action: deny in the PolicyLayer policy for wasm_agent_reset. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
wasm_agent_reset is provided by the Claude Flow MCP server (claude-flow). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
