Strengths

- •Recipe starters for common patterns like ARQC generation and clear-to-encrypted PIN blocks.
- •Validation audit maps every operation to specific vendor specs and standards.
Weaknesses
- •Software emulation only; cannot replace physical HSMs for production workloads.
- •Relies on Codex for implementation, requiring manual review of edge cases.

It flags concrete dangerous patterns (example: ADD COLUMN with DEFAULT) and prints step-by-step safe alternatives instead of vague warnings. The embedded Rhai-based custom checks are a smart move — teams can encode org policies — but usefulness will depend on CI integration and the breadth/precision of its rule set.
