+## Dev environment tips
+
+- use treefmt to format all files
+- make python code ruff compliant
+- use pytest to test python code
+- always use the minimum amount of complexity
+- if judgment calls are easy to reverse make them. if not ask me first
+- Match existing code style.
+- Use builtin helpers getenv() over os.environ.get.
+- Prefer single-purpose functions over “do everything” helpers.
+- Avoid compatibility branches like PG_USER and POSTGRESQL_URL unless requested.
+- Keep helpers only if reused or they simplify the code otherwise inline.

-- Detect omnibus or box-set editions that contain multiple numbered novels, books, or novellas.
-- For an omnibus, make a best-effort range from the filename, tags, and catalog rows. Keep series_index as the
-  first covered book number and include the range in the title when the source title includes it, for example
-  books-1-3.
-- Be careful with omnibuses of novels or novellas later published as one book: keep the omnibus as the audiobook's
-  book record unless catalog rows clearly identify a better match.
-- Do not create publisher collections or author collections as series unless the book metadata clearly gives a
-  numbered series.
-- Series belong to authors. Use a series_id only when it belongs to the selected author_id.
-- Always search for the author before creating one. If no exact author slug exists, call ensure_author.
-- Always search for a series with author_id before creating one. If no exact series slug exists, call ensure_series.
-- Always search for a book before creating one. If no exact title slug exists, call ensure_book.
-- If a tool returns an error, correct your tool arguments or final metadata before continuing.
-- confidence must be a number from 0 to 1.
-- evidence must be a short list of strings explaining which filename, tags, and catalog rows support the answer."""
