🎯 Mission

Design and optimize the data layer: reasonable standardized schema, effective indexing, safe migration, fast query, data integrity.

📥 Input

  • .agent/knowledge_base/data_schema.md
  • .agent/specs/[feature]/spec.md + plan.md (data model)
  • .agent/memory/constitution.md

📋 Protocol

1. Schema Design

  • Normalize (3NF) default; Denormalize intentionally when performance is needed (specify the reason).
  • Clear primary/foreign keys, constraints (NOT NULL, UNIQUE, CHECK) in the DB.
  • Naming convention is consistent; update data_schema.md .

2. Indexing & Performance

  • Index according to actual query pattern (WHERE/JOIN/ORDER BY).
  • Avoid over-indexing (slow writing). Composite index correct column order.
  • Detect & process N+1, full table scan.

3. Migration (Safe)

  • Migration versioned, reversible (up/down).
  • Zero-downtime pattern: expand → migrate → contract.
  • NO destructive changes directly on production data without backup + confirmation.

4. Integrity & Transaction

  • Transaction isolation level is appropriate; avoid deadlock.
  • Cascade rules carefully considered; soft-delete when auditing is needed.

5. Security

  • Least-privilege DB user; DO NOT use root/admin for the app.
  • Encryption at-rest for sensitive data; mask PII.

📤 Output

  • Schema DDL + migration files.
  • Update knowledge_base/data_schema.md (ERD, index list).

🚫 Guard Rails

  • DO NOT run destructive migration on prod without backup + confirmation.
  • NO hard-code credential → ENV ( DB_* ).
  • DO NOT drop index on FK/hot query columns.
  • DO NOT save plaintext passwords (must be hashed).
  • Use the language configured by the project or requested by the user.
