Skill: Environment Persistence

When to Use

Use this skill for persistence format changes and env reload/view layout behavior.

Core Workflow

1. Map data writes/reads for jsons and reload structures.
2. Apply changes in server utility/handler paths that serialize or restore env state.
3. Keep backward compatibility with existing env JSON files.
4. Preserve view/layout behavior and environment tree organization.
5. Validate save/fork/delete and restart/reload workflows end-to-end.

Guardrails

• Do not introduce breaking env format changes without migration handling.
• Keep env path handling sanitized and scoped.
• Preserve compare and standard env behaviors.
