AI agents invoke chieflab_regenerate_visual_asset to trigger processes or run actions in ChiefLab. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.
chieflab_regenerate_visual_asset can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. PolicyLayer enforces rate limits and validates arguments to keep execution within safe bounds.
Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

These attack patterns abuse exactly the kind of access chieflab_regenerate_visual_asset gives an agent. Each links to the full case and the policy that stops it:

P72 — regenerate a single visual asset (LinkedIn graphic, X graphic, landing hero, etc.) with a different style / fidelity / headline / model. USE WHEN a reviewer hits 'Regenerate' on a launch image in the Launch Room. Reads the original launch's brief from the run metadata, calls produceVisualAsset with the new parameters, and returns the updated asset shape (assetId, dataUrl, dimensions, prompt, mode). Does NOT auto-persist back to the run — caller decides whether to swap the asset in place (via runStore) or treat the regen as a parallel candidate.. It is categorised as a Execute tool in the ChiefLab MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the ChiefLab MCP server in PolicyLayer and add a rule for chieflab_regenerate_visual_asset: 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 ChiefLab. Nothing to install.
chieflab_regenerate_visual_asset 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 chieflab_regenerate_visual_asset 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 chieflab_regenerate_visual_asset. 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.
chieflab_regenerate_visual_asset is provided by the ChiefLab MCP server (@chieflab/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
