Level 1: Quick Start

Overview

The legacy-bridge skill provides backward compatibility for existing @load patterns used in CLAUDE.md and the product-matrix system. This bridge enables a zero-breaking-change migration path from the legacy standards loader to the new Skills-based architecture.

Migration Timeline: 6-month transition period (deprecation warnings only, no breaking changes)

When to Use

Use this skill when:

• You have existing code using @load product:* patterns
• You need to maintain backward compatibility during migration
• You want to gradually transition to the new Skills format

Quick Reference

Legacy Pattern	New Skill Loading
@load product:api	skill-loader.py load product:api
@load CS:python	skills/coding-standards/python
@load SEC:*	skills/security/* + NIST baseline

Level 2: Implementation

Pattern Translation

The legacy-bridge automatically translates old @load patterns to new skill loads:

Product Type Patterns

# Old Pattern → New Skill Loading
@load product:api         → Load: [coding-standards, testing, security, devops]
@load product:web-service → Load: [coding-standards, testing, security, frontend, devops]
@load product:frontend-web → Load: [frontend, testing, security]

Standard Code Patterns

# Coding Standards (CS)
@load CS:python       → Load: skills/coding-standards/python
@load CS:javascript   → Load: skills/coding-standards/javascript

# Testing Standards (TS)
@load TS:pytest       → Load: skills/testing/pytest
@load TS:*            → Load: skills/testing/* (all testing skills)

# Security Standards (SEC)
@load SEC:auth        → Load: skills/security/authentication
@load SEC:*           → Load: skills/security/* + NIST-IG:base
