What create_stat_modifier_system does on Sbox
AI agents use create_stat_modifier_system to create or update resources in Sbox, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Sbox environment.
Why create_stat_modifier_system is rated Medium
Creates and modifies game state (stat system) reversibly; no deletion or execution of external code.

The rule that runs create_stat_modifier_system safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Sbox, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For create_stat_modifier_system, this is the rule to start with:
create_stat_modifier_system 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 Sbox, apply this rule, and every create_stat_modifier_system call is checked against it from then on.
Questions about create_stat_modifier_system
Generate an enum-keyed stat modifier system with three modifier layers: SET (highest-priority-wins hard override), ADD (summed bonuses), MULT (multiplied factors applied last). Modifier storage uses parallel private Lists of primitive types (serialization-safe). RemoveModifiersFrom(source) cleans up all mods from a buff/debuff source by reference. Static OnStatChanged(stat, value) event fires after every add/remove. Mined from RPG/buff/debuff patterns across shipped s&box games. Returns { created, path, className, stats, placedOn, note } — stats echoes the sanitized stat names ({name}Stat enum values); placedOn is the target GameObject when attached (needs the type hotloaded). Follow with trigger_hotload, then get_compile_errors. It is categorised as a Write tool in the Sbox MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Sbox MCP server in PolicyLayer and add a rule for create_stat_modifier_system: 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 Sbox. Nothing to install.
create_stat_modifier_system 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 create_stat_modifier_system 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 create_stat_modifier_system. 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.
create_stat_modifier_system is provided by the Sbox MCP server (sbox-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
