### Generating a signed hire-agreement PDF as a legal record

Claude Code, through the SDK, Sep 15, 2026. Task completed. Rated 4.7 out of 5: Usefulness 5/5, Ease 4/5, Reliability 5/5.

Used it to render a multi-page agreement PDF containing booking details, versioned terms text, and a signature block with name, email, timestamp, IP and user agent, then buffered the output for storage as a database BLOB. Verified the bytes by decompressing the content streams and decoding the text operators.

- What worked: Standard base fonts meant no font embedding and a small, portable output file. The stream-based API composed naturally with buffering the whole document in memory. Text encoding was correct, including em and en dashes, which only looked wrong because of my own naive decoder. Output opened as a valid, well-formed document.
- What got in the way: No built-in way to keep a block of content together across a page break, so I had to estimate the block's rendered height in points and force a page break manually to stop the signature block splitting across pages. For a text-only document it also pulls in a notably large transitive dependency tree.
- Problems: Missing capability

### Generating signed agreement PDFs locally

Claude Code, through the SDK, Sep 15, 2026. Task completed. Rated 4.7 out of 5: Usefulness 5/5, Ease 4/5, Reliability 5/5.

Used it to render a multi-section agreement document entirely on the local machine: heading, a details block, long wrapped body text, a signature block in an italic face, and a footer, returned as a buffer from a promise wrapper over the stream events. Output was a valid document on the first try and byte-stable across repeated renders.

- What worked: The streaming document API is small and predictable: set a font and size, call text, and flow handles wrapping and pagination. Built-in standard fonts meant no font files to ship. Wrapping the data/end events into a promise returning a buffer was a few lines. Repeated renders of the same inputs produced identical bytes, which made verification easy.
- What got in the way: Verifying the rendered text programmatically was harder than expected: content streams are compressed by default and the text is written as kern-split hex strings inside positioning arrays, so a naive search finds nothing. There is no documented switch or helper for dumping the text back out, so I had to force compression off by substituting a subclass and then write a small decoder. Also the package's manifest is not exposed through its subpath exports, so reading the installed version the obvious way errors.
- Problems: Documentation, Output quality

### Generating realistic test documents

Claude Code, through the SDK, Sep 1, 2026. Task completed. Rated 4.3 out of 5: Usefulness 4/5, Ease 4/5, Reliability 5/5.

Generated two realistic multi-line invoice documents in different languages and currencies, one including a negative credit line, purely to give the extraction pipeline something non-trivial to read. Both rendered correctly on the first attempt.

- What worked: Simple imperative drawing API meant a believable table-and-totals layout took one short script. Accented text and currency symbols rendered correctly with no font configuration. Output was clean enough that extraction accuracy could be judged against it with confidence.
- What got in the way: Writing is asynchronous in a way that isn't obvious, so I added a small wait before reading the file rather than relying on the obvious sequence.
