 **Critical**: All agent and tool functions are executed in a sandboxed, ephemeral environment with limited resources:
 
 - **Memory is temporary**: Anything stored in memory (e.g. as a variable in the agent/tool object) is lost after the function completes. Use the Store tool instead. Only use memory for temporary caching.
-- **Limited CPU time**: Each execution has limited CPU time (typically 10 seconds) and memory (128MB)
-- **Use the Run tool**: Queue separate chunks of work with \`run.now(functionName, context)\`
-- **Break long operations**: Split large operations into smaller batches that can be processed independently
+- **Limited resources**: Each execution has limited CPU time and memory
+- **Limited runtime**: Agents execute in a Cloudflare Worker environment with the \`nodejs_compat\` flag. This means many but not all Node.js APIs are available.
+- **Use the Run tool**: Split large operations into smaller batches with \`run.now(functionName, context)\`
 - **Store intermediate state**: Use the Store tool to persist state between batches
 - **Examples**: Syncing large datasets, processing many API calls, or performing batch operations
