The architecture is already in your code

A useful map should help you find the implementation, not become another document you have to keep in sync.

Panolayer architecture view of a connected codebase

Start with the source

An architecture diagram is useful when it reflects how the application is actually structured. Panolayer derives its view from source so you can explore system areas, follow relationships, and reach individual functions and symbols.

Change the level of detail

High-level views help you plan and direct agent work. A source-level view helps you inspect an assumption, a rule, or a precise correction. Engineers need both perspectives, and a clear path between them.

Move between the map and the code

The overview is only useful if it leads somewhere. From a system area, follow relationships down to the function you want to change — then back up to see what else the decision touches.

  • Explore system areas before assigning work to an agent.
  • Follow callers to understand the blast radius of a change.
  • Reach exact functions and symbols without leaving the view.

Attach findings to the place they matter

A list of warnings is only a starting point. When a finding is connected to its source and the relevant callers, it becomes easier to understand why it matters and what should happen next. Coverage still depends on the language, framework, and available context.
