1-185: LGTM!The documentation clearly describes the sample files and their intended uses. The usage examples and CLI commands are helpful for users getting started with office document processing.
Note: Static analysis flagged "full year" (line 72) as potentially needing a hyphen ("full-year"), but this is a minor stylistic point that doesn't affect clarity.

1-237: LGTM!Comprehensive documentation covering prerequisites, provider support, usage examples, and best practices. The quick start section and code snippets are particularly helpful for users.
Note: Static analysis flagged "XLSX spreadsheet" (line 62) as redundant since "S" stands for spreadsheet, but this phrasing is commonly used for clarity and doesn't impact readability.

185-210: LGTM!The Office Documents section is well-integrated into the examples README, following the established structure and providing clear run commands. The link to the detailed documentation in
office-documents/README.mdhelps users find more information.Note: Consistent with the office-documents README, static analysis flags "XLSX spreadsheet" as redundant, but this is a minor stylistic point that aids clarity.

Remove references to missing DOCX files or add the files to the repository.
Example 5 (contractComparison) references sample-contract.docx and amended-contract.docx at lines 197-198, but neither file exists in examples/office-documents/data/. The example will fail at runtime. Either add these files to the repository or remove this example.

In examples/office-documents/contract-analysis.ts around lines 196 to 199, the
officeFiles array references
./examples/office-documents/data/sample-contract.docx and
./examples/office-documents/data/amended-contract.docx which are missing and
will cause runtime failure; fix by either adding the two .docx files into that
data/ directory (committing them to the repo) or remove/replace this example
entry — alternatively guard the example with a file-existence check and skip or
log a clear error if the files are absent.

Both PPTX files referenced in this example are missing from the repository.
Example 7 at lines 292-295 references quarterly-report.pptx and annual-review.pptx, but neither file exists in examples/office-documents/data/. The directory contains only a README.md file. This will cause the example to fail when executed. Either add the missing files or remove/update the example to use available test data.

In examples/office-documents/presentation-summary.ts around lines 292-295 the
example references two PPTX files that are not present in
examples/office-documents/data/, causing runtime failures; fix by either adding
the missing files (quarterly-report.pptx and annual-review.pptx) into that data
folder, or update the officeFiles array to point to existing test assets (or
safer test placeholders) in the repo, and optionally add a simple existence
check that skips/mocks missing files and logs a clear warning so the example
runs even if the real PPTX files are not present.

[nitpick] The sample data documentation references "Q3 2024 performance" and a date range of "January 2024 - September 2024", which are now in the past. Consider updating these to use more recent time periods (e.g., "Q3 2025" or using relative terms like "previous quarter") to keep the examples feeling current and relevant.
