A quiet day of paying down doc debt

Some days are about shipping a feature. Today was about making sure the next six months of features don’t rot under their own documentation. Chalie’s backend had accumulated the kind of docstrings that restate the function signature back at you — param: the parameter — instead of telling you the one thing you actually need to know before you touch the code: what breaks, what’s not obvious, what side effect will bite you. I set out to fix that everywhere, batch by batch, without touching a single line of actual logic.

The rule I held the whole way through: keep only non-obvious behaviour, exceptions, and side-effects; delete restated signatures, paraphrased code, and parameter descriptions that add nothing a type hint doesn’t already say. Eighteen commits landed today, sweeping the abilities framework core and internals, the full api routes layer, capabilities (mail, calendar, contacts, home integrations), the channel configs that drive background processing, the MCP server entry point, runtime config, dev scripts, and a first pass through the services package — decay, deliberation, embeddings, episodic memory, geo, images, and the database layer itself. Every single file was validated against Python’s own parser before and after — if a docstring edit could not prove it left the code untouched, it didn’t ship. That’s the difference between “cleaning up docs” and “quietly breaking things while cleaning up docs.”

Why bother with something this unglamorous? Because docstring noise is a tax that compounds. Every contributor — human or otherwise — who opens a file with a bloated docstring has to read past six lines of restated obviousness to find the one sentence that matters. Multiply that by hundreds of files and it becomes real drag on how fast anyone can safely change Chalie. Trimming it now, deliberately and file-by-file with a hard validation gate, is cheaper than trimming it later under pressure with a deadline.

The day wasn’t purely archaeological. A document-attachment bug got its accessibility follow-up: the hidden file-picker inputs for both images and documents in the chat composer were missing accessible names, which SonarCloud flagged as a real screen-reader gap — you can’t announce an input that has no label. Both got aria-labels, closing the loop on the attachment-flow work landing around the same window. It’s a small fix, but it’s the kind of small fix that matters most to the people who rely on it: users navigating Chalie with assistive tech don’t get to notice that a file input “mostly” works.

Nothing about today changes what Chalie does. Everything about today changes how fast the team can keep improving what Chalie does without tripping over its own explanations. The docstring sweep kept going past this point — by the time it wrapped, it touched dozens more files across services, tests, and integration layers — but today’s slice, batches one through eighteen, is the one that proved the process: trim aggressively, validate every file, never let a “just docs” commit become a silent behaviour change.

• 18 commits trimmed docstrings across abilities, api routes, capabilities (mail/calendar/contacts/home), channel configs, MCP server, runtime, dev scripts, and the first services pass (decay, deliberation, embeddings, episodic, geo, image, database)

• Every file validated with Python’s own parser before shipping — the rule was zero tolerance for a “docs-only” commit that touches behaviour

• Rule of thumb applied uniformly: keep non-obvious behaviour, exceptions, and side-effects; delete restated signatures and parameter descriptions

• Hidden file-picker inputs for image and document attachments in the chat composer got accessible names, closing a real screen-reader gap

• Sets up the second half of a documentation sweep that continues trimming the services package, test suites, and integration layers in the days after
