[](https://jxnl.co/writing/2025/08/27/facets-context-engineering/#__codelineno-3-15)    Key insight: Multiple chunks from same source = use load_pages() instead of fragments.

[](https://jxnl.co/writing/2025/08/27/facets-context-engineering/#__codelineno-3-18)    Tool usage guidance: When writing tool descriptions, think like you're training a new team member. Make implicit knowledge explicit—specialized query formats, terminology definitions, and relationships between resources. Ambiguous parameter names like "user" should become "user_id" for clarity.

[](https://jxnl.co/writing/2025/08/27/facets-context-engineering/#__codelineno-3-20)    Error handling strategy: If tool calls fail validation, return actionable error messages that guide agents toward correct usage rather than cryptic error codes. For example: "Date filter requires YYYY-MM-DD format, received '2024/03/15'" instead of "ValueError: invalid date format".
