Custom instructions in Cortex Analyst provide unique business context to the LLM to control SQL query generation. These instructions are provided in natural language within the semantic model YAML. This means the engineer should describe the desired behavior (grouping by 'customer_segment' and presenting as a percentage) in plain English for the LLM to interpret and apply, making option C correct. Option A is incorrect because 'custom_instructionS guide the LLM's *generation* process, not directly inject SQL snippets. Option B is incorrect as custom instructions are part of the YAML, not a separate Python file. Option D is incorrect; while Copilot's custom instructions have a 2,000 character limit, the source does not specify such a limit for Cortex Analyst's semantic model 'custom_instructionS , and the 'task_description' for 'CLASSIFY _ TEXT is limited to about 50 words. Option E is incorrect; the 'custom_instructions' in the semantic model are part of the shared model definition, not user-specific in the way Snowflake Copilot's custom instructions are.
