What problem does it solve?

This Skill helps you recover when Refactoring Safety Net (RSN) checks fail after you change code inside a vuln-code-snippet block, preventing snippet and “Fix It” variations from drifting out of sync.

Core Features & Use Cases

• Detect RSN breaks with a single check: Run the project RSN validator to identify exactly which challenge codefix files no longer match the locked snippet state.
• Map source snippets to codefix outputs: Determine the affected challengeName snippets by finding the corresponding vuln-code-snippet blocks and the matching codefix files.
• Apply consistent, intent-preserving repairs: Update all related codefix files so non-vulnerable lines stay identical while corrected vulnerable lines reflect the intended fix in the _correct variant.

Quick Start

Run the RSN check with npm run rsn, then update the listed data/static/codefixes challengeName_*.ts files to match the modified snippet block and re-run npm run rsn to confirm it passes.
