WHAT IT DOES

What task_assign does on Claude Flow

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

RISK

Why task_assign is rated Medium

The tool creates and persists task records in a database (.swarm/memory.db) with associated metadata (assignment, dependencies, analytics). This is a reversible data modification operation—tasks can be updated or removed—making it Write rather than Destructive.

From the tool's definition Assign a task to one or more agents; creates or modifies data in .swarm/memory.db (task assignment, dependency tracking, completion analytics); persistent state changes across sessions.

RECOMMENDED RULE

The rule that runs task_assign 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 task_assign, this is the rule to start with:

task_assign Rate-limited

task_assign 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.

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

FAQ

Questions about task_assign

What does the task_assign tool do? +

Assign a task to one or more agents Use when native TodoWrite is wrong because you need cross-session task persistence, agent assignment, dependency tracking, or completion analytics in the .swarm/memory.db. For in-session checklists native TodoWrite is simpler and faster. It is categorised as a Write tool in the Claude Flow MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on task_assign? +

Register the Claude Flow MCP server in PolicyLayer and add a rule for task_assign: 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.

What risk level is task_assign? +

task_assign is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit task_assign? +

Yes. Add a rate_limit block to the task_assign 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.

How do I block task_assign completely? +

Set action: deny in the PolicyLayer policy for task_assign. 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.

What MCP server provides task_assign? +

task_assign 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.
