Your Schema Is Your Prompt: Agent Design Moves into the Data Model
For SQL-native agents, schema design is not just database engineering; it is simultaneously tool design, prompt engineering, and context assembly, so teams should invest in data modeling and curated views rather than bespoke prompt plumbing.
AngleArgue that agent builders should treat schema migrations, views, and semantic table design as their primary prompt-engineering surface, with worked examples of schema choices that change agent behavior.

Tool result serialization is a first-class context-engineering decision; for tabular SQL results, CSV often halves token consumption versus JSON and should be the default output format for agent tools.
AngleQuantify and explain why CSV wins for LLM-readable tabular data, show where JSON remains necessary for nested structures, and provide implementation patterns for CSV-emitting SQL tools.

A single universal SQL tool can replace many specialized retrieval tools; reducing tool count lowers tool-selection errors and framework complexity, following the same arc as code search returning to grep.
AngleContrast multi-tool agent stacks with a single SQL interface, examine when universality beats narrow tools, and discuss failure modes where SQL is not enough.

Agent SQL safety is better enforced through database-native primitives such as read-only roles, read replicas, row limits, tenant-scoped config, and rolled-back transactions than through custom application-level allow-lists.
AngleArgue for pushing guardrails down into the data platform, show how existing permissions and resource limits can be reused across agents and humans, and identify remaining risks.
