  • Optimize API query parameters Use the most efficient query parameters in your API to reduce the amount of data being processed and returned. This can help improve the performance of your plugin and reduce the likelihood of reaching rate limits.
  • Test several descriptions and instructions Find the most effective way for the LLM to understand and use your plugin.
  • Maintain and iterate on your plugin Work on improving the descriptions in your OpenAPI specs. The specs will be used by ChatGPT to interact with your plugin. Monitor your plugin's performance and feedback to identify issues and areas of improvements. Keep your Open API file up-to-date so that it keeps providing your teams or your end users value.
