📝 WalkthroughWalkthroughAdds a new PDF form-filling script and companion README. The script autodetects PyMuPDF or pypdf, maps mock patient and prescription data to form fields (including checkboxes and signature), and writes a filled PDF; the README documents installation and usage steps. Changes

2-11: Docstring lists pypdf first, but PyMuPDF is the preferred/primary library.The module docstring (lines 6–7) says "This script requires pypdf" before mentioning PyMuPDF as an alternative, which inverts the actual priority (PyMuPDF is tried first and recommended). Swap the order to match the runtime behavior.

Inline comments:
In `@scripts/fill_pdf_form.py`:
- Around line 78-79: The mock data in scripts/fill_pdf_form.py is inconsistent:
the "diagnosis" field currently reads "Chronic migraine without aura,
intractable, with status migrainosus" while documentation/profile state "with
aura"; update the "diagnosis" value to match the intended scenario (e.g.,
"Chronic migraine with aura, intractable, with status migrainosus") or, if the
diagnosis is correct, update the README/profile to match; also verify that the
"icd_code" ("G43.709") corresponds to the chosen wording and adjust it if
necessary so the "diagnosis" and "icd_code" fields are consistent.
- Around line 279-302: The pypdf fallback in fill_pdf_with_pypdf is a no-op
because update_page_form_field_values is called with an empty dict; change
fill_pdf_with_pypdf to either (A) build and pass a real field mapping by
iterating reader.get_form_text_fields() and mapping those names to values
(mirroring the PyMuPDF field names used elsewhere) before calling
writer.update_page_form_field_values(writer.pages[0], mapping), or (B) if you
don't want to implement filling, replace the silent behavior with a clear
warning and a non-success signal: log/print a message indicating pypdf
form-filling is unsupported for this PDF and ensure main() does not print
"Successfully filled PDF form!" when no fields were filled (e.g., return a
status or raise an informative exception). Ensure references to
reader.get_form_text_fields(), update_page_form_field_values, and
fill_pdf_with_pypdf are updated accordingly so the caller can detect and handle
the no-op case.
- Around line 305-331: The main() function prints a success message
unconditionally even if fill_pdf_with_pymupdf or fill_pdf_with_pypdf raises;
wrap the branch that calls these functions in a try/except around the fill
call(s) (guarded by USE_PYMUPDF / USE_PYPDF), catch Exception as e, print a
clear error including e (and optionally the input/output paths and
PATIENT_DATA['patient_name']), and sys.exit(1) on failure so the final success
prints only run when the fill completes without exception.
- Around line 143-276: The function fill_pdf_with_pymupdf currently opens the
PDF with fitz.open(input_pdf_path) and calls doc.save(...) then doc.close(),
which leaks the fitz.Document if doc.save raises; change to open the document
using a context manager (with fitz.open(input_pdf_path) as doc:) so the document
is always closed even on exceptions, move all code that uses doc (page = doc[0],
widgets collection, widget updates, the widgets_to_update loop, and doc.save
call) into that with-block, and remove the explicit doc.close() call; keep
references to functions set_widget_value, set_checkbox, and the widget
update/exception handling unchanged.
- Around line 17-31: The boolean flags for PDF libraries are not both
initialized, so USE_PYPDF can be undefined when fitz (PyMuPDF) imports
successfully; to fix, initialize USE_PYMUPDF = False and USE_PYPDF = False
before any imports, then in the existing try/except set USE_PYMUPDF = True when
import fitz succeeds and set USE_PYPDF = True inside the inner except when
importing PdfReader/PdfWriter from pypdf succeeds, ensuring both flags always
exist for later checks (references: USE_PYMUPDF, USE_PYPDF, import fitz, from
pypdf import PdfReader, PdfWriter).
In `@scripts/README-fill-pdf.md`:
- Around line 42-44: Rename the misspelled asset and all references from
"co-prescription-drug-prior-authorizathion-request-form.pdf" to
"co-prescription-drug-prior-authorization-request-form.pdf"; update the README
entry and the script fill_pdf_form.py (replace occurrences such as
TEMPLATE_PATH, OUTPUT_FILENAME or any variables/constants and the save path used
around lines 309–310) so the script reads the corrected template name and writes
the filled PDF to "...-authorization-request-form-filled-jane-doe.pdf"; ensure
any other references in the repo (tests, docs, asset lists) are updated to the
corrected filename.

The pypdf fallback fills zero fields — it's effectively a no-op.
update_page_form_field_values on line 293 receives an empty dict {}, so the "filled" output is identical to the input. This is misleading because main() prints "Successfully filled PDF form!" regardless. Either populate the field mapping (mirroring the PyMuPDF field names) or clearly warn the user that pypdf support is incomplete.
Option A: stub out with a clear warning

- Initialize USE_PYMUPDF/USE_PYPDF flags up front to avoid NameError - Fix diagnosis inconsistency: "without aura" → "with aura" (matches profile/README), update ICD code to G43.109 - Use context manager for fitz.open to prevent resource leak on save failure - Add warning for unimplemented pypdf fallback instead of silent no-op - Wrap fill call in try/except so success message only prints on actual success - Fix "authorizathion" typo → "authorization" in filenames Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
