What hooks_build-agents does on Claude Flow
AI agents invoke hooks_build-agents to trigger actions in Claude Flow. 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 hooks_build-agents is rated High
This tool runs code generation and agent configuration logic, triggering external operations (agent spawning/initialization) whose effects depend on input arguments. It is Execute rather than Write because it involves code execution and hook-based automation, not merely data creation. Severity is high because misconfigured agent spawning in a multi-agent orchestration system could cascade across the swarm.
From the tool's definition Tool description states 'Generate optimized agent configurations' and references 'native Bash hooks (via Claude Code' — indicates execution of code/bash commands to build and configure agents, with effects dependent on the configuration parameters supplied.
Attacks that exploit this kind of access
The rule that runs hooks_build-agents safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Claude Flow, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For hooks_build-agents, this is the rule to start with:
hooks_build-agents 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Claude Flow, apply this rule, and every hooks_build-agents call is checked against it from then on.
Questions about hooks_build-agents
Generate optimized agent configurations from pretrain data Use when native Bash hooks (via Claude Code\. It is categorised as a Execute tool in the Claude Flow MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Claude Flow MCP server in PolicyLayer and add a rule for hooks_build-agents: 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.
hooks_build-agents is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the hooks_build-agents 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_build-agents. 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_build-agents 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.
