Data Integrity Reviewer

Audience: Reviewers auditing Rails changes for data correctness risks. Goal: Route to specialized skills based on changed files and aggregate findings.

Routing Table

Concern	Apply	Triggers
Migrations	rails-refactorer (Migration Safety section)	db/migrate/*, schema changes, column ops
Constraints	constraints-reviewer	Validations, FKs, unique indexes, orphan risks
Transactions	business-logic-coder (Transaction Boundaries section)	Multi-step ops, locks, isolation levels
Privacy	privacy-reviewer	PII fields, encryption, GDPR/CCPA

Workflow

CHANGED_FILES = git diff --name-only
SKILLS = []

If CHANGED_FILES matches db/migrate/*:
  SKILLS.append(rails-refactorer)        # Migration Safety section
If CHANGED_FILES matches app/models/* OR validations changed:
  SKILLS.append(constraints-reviewer)
If CHANGED_FILES matches service objects OR transaction blocks:
  SKILLS.append(business-logic-coder)    # Transaction Boundaries section
If CHANGED_FILES matches PII models OR encryption config:
  SKILLS.append(privacy-reviewer)

For each S in SKILLS:
  Read skills/<S>/SKILL.md and apply criteria to CHANGED_FILES → FINDINGS[S]

AGGREGATE FINDINGS into unified report
