Agent of the Day – September 10, 2026

Sep 10, 2026

Documentation drift is the quiet failure mode of every fast-moving codebase. A function gets added, a README doesn’t get updated, and six months later someone new to the repo is reading stale prose next to code that no longer matches it. Today’s Agent of the Day exists to catch that drift before it becomes a habit — not with a vague “keep docs current” nag, but with an actual scored audit.

Agent of the Day: Package Specification Librarian

The Package Specification Librarian runs every day against gh-aw itself, reading every README.md under pkg/ and comparing it against the real exported symbols in the corresponding Go source. It’s not looking for typos or style nits — it’s checking whether the documentation still tells the truth about the code.

Its most recent run, #34481937715 on September 10, took 16.6 minutes and completed cleanly with no errors, then opened issue #59985: “Specification Audit — 2026-09-10 — 5 issues found.” The report is refreshingly precise about scope. Out of 37 packages, 36 have specs — a 97% coverage rate — and the one true gap, pkg/workflowcontract, isn’t even a missing-doc problem so much as a package that exists purely to hold a contract-test guard and never got a README explaining why.

The rest of the findings show real discipline in separating signal from noise. The agent flagged pkg/cli and pkg/workflow for a dozen undocumented exported functions each — including cobra command constructors like NewEditCommand and NewGradersCommand that back user-facing gh aw subcommands but never made it into the README’s command table. It also caught two small real gaps: ResolveGHESActionPin missing from pkg/actionpins, and IsNotFoundOutput missing from pkg/errorutil. Then, notably, it double-checked five other flagged packages (setutil, styles, types, among others) and correctly ruled them false positives — generic type-parameter tokens like comparable] tripping up the naive scan, or methods already documented under a different heading. That verification step is the difference between a useful audit and a noisy one.

Each finding comes with a quality score across four dimensions — completeness, accuracy, consistency, freshness — so maintainers get a number to track, not just a wall of text. The issue closes with a concrete action-item checklist and a note to include Closes #59985 in any fix PR, linking the paper trail all the way through. Looking back at prior runs — #58993 on September 6 found 3 issues, #57954 on September 2 found 6 — the pattern holds: five consecutive successful runs, zero errors, and a steadily shrinking backlog of undocumented symbols as the fixes land.

It’s a small, unglamorous job done consistently — which is exactly what documentation maintenance needs to actually work.
