Marketplace code-consistency-validator

Validates type consistency across Rust, TypeScript, PostgreSQL boundaries. Use when reviewing code, debugging type mismatches, or validating API contracts. Triggers on: check consistency, validate types, find mismatches, cross-language.

Code Consistency Validator

Validates type consistency across Rust, TypeScript, and PostgreSQL boundaries.

When to Use

Reviewing code for type mismatches
Debugging precision loss issues
Validating API contracts between languages
Checking BigInt/Number conversions
Auditing cross-language data flow

Workflow

Step 1: Run Quick Grep

Use provided grep commands to find potential issues.

Step 2: Check Critical Patterns

Look for Number() on wei/balance, parseInt without radix.

Step 3: Generate Report

Report findings using severity levels (CRITICAL/WARNING/INFO).

Critical Type Mappings

Rust	TypeScript	PostgreSQL
i64/u64	bigint (not number!)	BIGINT
U256	string	DECIMAL(36,18)
f64	number	DOUBLE PRECISION

🔴 CRITICAL Patterns

Number(response.profit_wei)  // ❌ Precision loss!
parseInt(hexBalance)         // ❌ Missing radix!
JSON.stringify({ amount: BigInt(x) })  // ❌ Fails!

Quick Grep

grep -rn "Number(" --include="*.ts" | grep -E "(wei|balance|amount)"
grep -rn "parseInt(" --include="*.ts" | grep -v ", 10)" | grep -v ", 16)"

Report Format

🔴 CRITICAL (funds at risk) 🟠 WARNING (potential bugs) 🟡 INFO (style) ✅ VALIDATED
