 Investigate before explaining; confirm every claim against the source.
 
 1. Locate the code: the router under `devplacepy/routers/`, the template under `devplacepy/templates/`, data helpers in `devplacepy/database.py`, schemas in `devplacepy/schemas.py`, and any service under `devplacepy/services/`.
-2. Read the matching domain section in `AGENTS.md` (the long-form companion) and the relevant part of `CLAUDE.md`.
+2. Read the matching nested `CLAUDE.md` for the subsystem (e.g. `devplacepy/services/devii/CLAUDE.md`), plus the relevant cross-cutting part of the root `CLAUDE.md`.
 3. Trace the data flow: input model (`models.py`) -> router handler + guard -> data helper -> response (HTML via `respond` + template, JSON via the `*Out` schema), plus the Devii action (`catalog.py`) and API docs (`docs_api.py`) where present.
 
 Then give a tight explanation:
 - What it does and where it lives, with `file:line` references.
 - The request pipeline and data flow.
