 "title": "Let coding agents edit SQL without leaving stale types",
 "page_title": "How to let coding agents edit SQL without leaving stale types with Reylo",
 "summary": "Keep each query in one .sql file so an agent cannot leave an old type behind, and let tsc find every caller.",
 "who": "A developer whose agent changes a query but forgets to update the matching TypeScript type.",
 "problem": "When types live apart from queries, agents fix one and leave the other stale.",
 "outcome": "Agent edits that are checked end to end: change the SQL, and the type check flags every caller it missed.",
 "steps": [
  "Set up Reylo as in its README so queries live in .sql files and types come from the SQL itself",
  "Point your agent at the docs as Markdown at Reylo.dev/llms.txt",
  "Ask the agent to change a query and then run the typecheck script",
  "Have it fix every caller the type check reports before it calls the task done"
 ],
 "agent_prompt": "Read reylo.dev/llms.txt, then in <project> change <query>.sql to <change>. Run the typecheck with --runExternalCode and fix every caller it reports. Do not hand-write any row types.",
 "agents": [
  "claude-code",
  "codex",
  "cursor"
 ],
 "difficulty": "Intermediate",
 "time": "20 minutes",
 "basis": "readme",
 "caveat": "The agent still needs access to the dev database for the type check to mean anything.",
 "category": "Software and DevOps",
 "tags": [
  "Software and DevOps"
 ],
 "lang": "rust",
 "requirements": [
  "TypeScript 7.1 (currently in beta), the first release with content mappers",
  "Node 24 or later",
  "A running dev database: Postgres, MySQL 8.0.22 or later, or a SQLite file",
  "A supported driver such as pg, postgres.js, mysql2, better-sqlite3, Bun.sql or Cloudflare D1"
