## Review Methodology & XML-Guided Workflow

**Primary Reference**: `@docs/developer-guides/general-code-review-procedure.md` - Complete review checklist for all file types

**XML-Style Systematic Review Pattern**:

```xml
<code-review>
  <pre-analysis>
    <file-categorization type="AUTOMATIC">
      <!-- Classify each file: TRPC_ROUTER, SERVER_ACTION, INTEGRATION_TEST, etc. -->
    </file-categorization>
    <critical-safety-scan>
      <!-- MANDATORY: Check for absolutely forbidden patterns -->
    </critical-safety-scan>
  </pre-analysis>

  <systematic-validation>
    <category-specific-checks category="${FILE_CATEGORY}">
      <!-- Apply category-specific validation rules -->
    </category-specific-checks>
    <quality-gates>
      <!-- TypeScript, ESLint, tests, build validation -->
    </quality-gates>
    <pattern-compliance>
      <!-- SEED_TEST_IDS, worker-scoped testing, modern auth -->
    </pattern-compliance>
  </systematic-validation>

  <critical-issues-assessment>
    <memory-safety-violations severity="CRITICAL">
      <!-- PGlite memory patterns, system lockup prevention -->
    </memory-safety-violations>
    <security-boundary-validation severity="HIGH">
      <!-- Organization scoping, permission validation -->
    </security-boundary-validation>
    <architectural-compliance severity="MEDIUM">
      <!-- Pattern adoption, modernization opportunities -->
    </architectural-compliance>
  </critical-issues-assessment>

  <actionable-recommendations>
    <immediate-actions priority="CRITICAL">
      <!-- Must-fix issues blocking PR approval -->
    </immediate-actions>
    <pattern-opportunities priority="IMPROVEMENT">

## 🚨 CRITICAL: Mandatory Safety Validations

**⛔ ABSOLUTELY FORBIDDEN Patterns (BLOCKING)**:

### Memory Safety Violations

- **PGlite Memory Blowouts**: `createSeededTestDatabase()` in `beforeEach()`, `new PGlite()` per test
- **System Impact**: 20+ database instances = 1-2GB+ memory = system lockups
- **Required Pattern**: `import { test, withIsolatedTest } from "~/test/helpers/worker-scoped-db"`

### Migration File Creation

- **Pre-Beta Constraint**: NO migration files in `supabase/migrations/`
- **Forbidden Commands**: `drizzle-kit generate`, `npm run db:generate`
- **Context**: Zero users, schema in flux, velocity over safety

### Vitest Command Issues

- **Redirection Breaks Vitest**: `npm test 2>&1`, `vitest >>`
- **Cause**: Vitest interprets redirection as test name filters
- **Required**: Use `npm run test:brief`, `npm run test:verbose`

### Schema Modification Lock

- **Schema is KING**: Database schema locked and immutable
- **Code Conforms to Schema**: Fix TypeScript by adapting code, not schema
- **Seed Data Lock**: SEED_TEST_IDS architecture is complete and locked

### Database Naming Conventions

- **Table Names**: MUST use camelCase, not snake_case (Drizzle requirement)
- **Column Names**: Follow camelCase for consistency with TypeScript
- **Forbidden**: snake_case table/column names that break Drizzle patterns

## Systematic Review Workflow

### Phase 1: File Classification & Triage

```xml
<file-classification>
  <automatic-categorization>
    <pattern match="src/server/api/routers/*.ts">TRPC_ROUTER</pattern>
    <pattern match="src/app/actions/*.ts">SERVER_ACTION</pattern>
    <pattern match="**/*.integration.test.ts">INTEGRATION_TEST</pattern>
    <pattern match="src/components/**/*.tsx">REACT_COMPONENT</pattern>
    <pattern match="src/server/db/schema/*.ts">DATABASE_SCHEMA</pattern>
    <pattern match="**/*.test.ts">UNIT_TEST</pattern>
    <!-- Additional patterns from general review procedure -->
  </automatic-categorization>

  <impact-assessment>
    <memory-risk-files>INTEGRATION_TEST files</memory-risk-files>
    <security-critical-files>TRPC_ROUTER, SERVER_ACTION files</security-critical-files>
    <performance-impact-files>DATABASE_SCHEMA, SERVICE files</performance-impact-files>
  </impact-assessment>
</file-classification>
```

### Phase 2: Critical Safety Validation

```xml
<critical-safety-scan>
  <memory-safety-check>
    <scan-for patterns="createSeededTestDatabase|new PGlite|beforeEach.*PGlite">
      <severity>CRITICAL</severity>
      <action>BLOCK_PR</action>
      <message>Memory safety violation detected - will cause system lockups</message>
    </scan-for>
  </memory-safety-check>

  <migration-prevention>
    <scan-for patterns="supabase/migrations/|drizzle-kit generate|npm run db:generate">
      <severity>CRITICAL</severity>
      <action>BLOCK_PR</action>
      <message>Migration files forbidden in pre-beta phase</message>
    </scan-for>
  </migration-prevention>

  <vitest-safety>
    <scan-for patterns="npm test.*2>&1|vitest.*>>|npm test.*>">
      <severity>CRITICAL</severity>
      <action>BLOCK_PR</action>
      <message>Vitest redirection breaks test execution</message>
    </scan-for>
  </vitest-safety>

  <database-naming-compliance>
    <scan-for patterns="_table|table_name|snake_case_table">
      <severity>HIGH</severity>
      <action>REQUEST_FIX</action>
      <message>Table names must use camelCase, not snake_case (Drizzle requirement)</message>
    </scan-for>
  </database-naming-compliance>
</critical-safety-scan>
```

### Phase 3: Category-Specific Deep Analysis

  <trpc-router-validation>
    <security-patterns>
      <check>Organization scoping: eq(table.organizationId, ctx.organizationId)</check>

      <check>Performance: .prepare() for frequent queries</check>
    </modern-drizzle>
  </trpc-router-validation>

  <integration-test-validation>
    <memory-safety>
      <check>Worker-scoped pattern: withIsolatedTest usage</check>
      <check>NO per-test instances: createSeededTestDatabase forbidden</check>

    </memory-safety>
    <seed-architecture>
      <check>Hardcoded IDs: SEED_TEST_IDS usage</check>

      <check>Predictable data: no nanoid() or random generation</check>
    </seed-architecture>
  </integration-test-validation>

  <!-- Additional category validations from general review procedure -->
</category-analysis>
```

### Phase 4: Pattern Compliance Assessment

```xml
<pattern-compliance>
  <seed-test-ids-usage>
    <check type="unit-tests">SEED_TEST_IDS.MOCK_PATTERNS usage</check>
    <check type="integration-tests">Direct SEED_TEST_IDS constants</check>
    <check type="security-tests">ORGANIZATIONS.primary/.competitor</check>
    <check type="mock-contexts">createMockAdminContext() patterns</check>
  </seed-test-ids-usage>

    <check>@supabase/ssr usage (NOT deprecated auth-helpers)</check>
    <check>Server Component auth: createClient() patterns</check>
    <check>Server Action auth: withAuth wrapper patterns</check>

```xml
<quality-gates>
  <compilation>
    <command>npm run typecheck</command>
    <requirement>MUST pass without errors</requirement>
    <failure-action>BLOCK_PR</failure-action>
  </compilation>

  <linting>
    <command>npm run lint</command>
    <requirement>MUST pass without violations</requirement>

## Continuous Improvement Integration

**ADDITIVE ARCHITECTURE**: This agent and the general review procedure are designed to be continuously updated as new patterns and "don'ts" are discovered during development.

**Update Process**:

1. New patterns discovered → Update both general review procedure and this agent
2. New forbidden patterns found → Add to critical safety validations
3. New quality gates needed → Integrate into validation commands
4. Performance insights gained → Update expectations and patterns

**Synchronization Reminder**: See CLAUDE.md for documentation synchronization requirements when patterns evolve.
