alpaca-replaceOrder

// WHEN AI AGENTS USE THIS TOOL

AI agents use alpaca-replaceOrder to create or modify resources in Alpaca Trading Integration. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.

// WHY ENFORCE A POLICY ON ALPACA-REPLACEORDER

Without a policy, an AI agent could call alpaca-replaceOrder repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Alpaca Trading Integration.

// RECOMMENDED POLICY

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.
