What agenticow_promote does on Claude Flow
AI agents use agenticow_promote 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.
Why agenticow_promote is rated Medium
Branch merging is a Write operation: it creates or modifies data (code history, branch state) reversibly. While merges can theoretically be undone via revert, they are not inherently destructive like deletions. The operation's scope (affecting one or more files/commits) and the potential for merge conflicts or unintended side effects in a development workflow justify medium severity rather than low.
From the tool's definition Tool name 'agenticow_promote' with description 'merge a branch' indicates a version control operation that modifies code repositories by integrating branch changes into a target branch.
Attacks that exploit this kind of access
The rule that runs agenticow_promote 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 agenticow_promote, this is the rule to start with:
agenticow_promote 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 agenticow_promote call is checked against it from then on.

agenticow_promote is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the agenticow_promote 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.
