Cross-Layer Consistency Check

Verify that a symbol (field name, enum value, status code) exists across all layers of the monorepo.

Usage

Run the bundled script:

bash ${CLAUDE_SKILL_DIR}/scripts/cross-layer-check.sh $ARGUMENTS

Examples

# Check a field name (substring match)
bash ${CLAUDE_SKILL_DIR}/scripts/cross-layer-check.sh invoiceNumber

# Check an enum value (exact word match)
bash ${CLAUDE_SKILL_DIR}/scripts/cross-layer-check.sh PAYMENT_SENT --exact

# Check a new DTO field
bash ${CLAUDE_SKILL_DIR}/scripts/cross-layer-check.sh paymentDueDate

What It Checks

The script searches across all source directories in order, reporting hits per layer:

• Backend / API source code
• Frontend source code
• Shared packages / libraries
• Test files
• Migrations / database schemas
• Configuration and documentation

Interpreting Results

• ✅ Layer: N hits — Symbol found in this layer
• ❌ Layer: no hits — Symbol NOT found — possible gap
• ⚠️ WARNING (< 3 layers) — Likely incomplete implementation

When to Use

• After adding a new field to a DTO
• After adding a new status code or enum value
• During MR review (Review Protocol point #2: cross-layer consistency)
• When the /review command flags potential cross-layer gaps
