Lilith self-improvement (Version 7+)

Lilith can extend herself only by creating tools in three categories:

| Category | Location | Examples | |----------|----------|----------| | Core | Agent-Core | Memory, time (rare; system-level) | | Addon | Agent-Addons | Weather, C# projects, apps | | Self | Lilith | Workspace files, self-improvement |

Layout

  • ShippedSource/ — copy of src/Version7 next to the built app (MSBuild CopyShippedSource)
  • {workspace}/output/self-improvement/live — current editable source
  • {workspace}/output/self-improvement/sandbox — clone for edits and builds
  • {workspace}/output/self-improvement/backups/{timestamp} — backups before promote

Tools

1. self_improve_get_source_layout 2. self_improve_generate_tool 3. self_improve_backup_live 4. self_improve_create_sandbox 5. self_improve_build_sandbox 6. self_improve_verify_sandbox_tool 7. self_improve_promote_sandbox — copies sandbox → live, builds, restarts

Set GENESIS_REPO_ROOT to the repo root when developing from source instead of ShippedSource.
