AI agents call hooks_worker-detect to retrieve information from Ruflo without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool analyzes or queries user prompts to identify worker triggers—a read-only operation that retrieves or classifies information without modifying state, executing code, or causing side effects. The incomplete description ('Use when native Bash hooks (via Claude Code\') is cut off but provides no evidence of write, execute, or destructive capability.
From the tool's definition Tool name 'hooks_worker-detect' and description indicate detection/analysis of worker triggers from user prompts. The phrase 'Detect worker triggers' suggests passive analysis with no data modification or external execution.

Register the Ruflo MCP server in PolicyLayer and add a rule for hooks_worker-detect: 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 Ruflo. Nothing to install.
hooks_worker-detect is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the hooks_worker-detect 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 hooks_worker-detect. 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.
hooks_worker-detect is provided by the Ruflo MCP server (ruvnet/ruflo). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
hooks_worker-detect is one line of Ruflo's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
