Inherit Legacy Style

Prevents AI code style drift in legacy projects by scanning the codebase for implicit conventions across 4 meta-architecture dimensions, resolving conflicts with the user one at a time, and crystallizing the consensus into an enforceable .ai-style-rules.md. Fully language- and framework-agnostic.

When to Activate

• User types /inherit-legacy-style
• User mentions onboarding AI onto a hand-written legacy project
• User is worried about AI-generated code "drifting" from existing project conventions
• User wants to extract and codify their project's implicit coding rules

When to Use

Use this skill when you need to preserve legacy project style and prevent AI-generated style drift. See When to Activate above for trigger conditions.

Prerequisites

• Git (recommended; non-Git projects fall back to file timestamps for incremental mode)
• Read/Write access to the project root (generates .ai-style-rules.md and optionally CLAUDE.md)
