Worth measuring your own split before quoting a number●BENCH — Terminal-Bench-Science 0.1 climbs from 24.7% on Fable 5 to 52.6%. Anthropic also states a standard error of 3.5-4.5 points, which is worth remembering before reading small gaps as real●SAFEGUARDS — Sharper cyber safeguards cut interventions in Claude Code sessions by roughly 60% on average.

Let the Downstream Task Verify the Upstream Actually Ran Today: A Completion Ledger and Dependency Barrier for Unattended Schedulers

Unattended schedulers have no notion of dependencies, so when a morning data-refresh task fails silently, the noon generation task keeps running on yesterday's leftovers. This is a design for recording upstream completion atomically and having downstream assert its preconditions before running, with working TypeScript and lessons from my own operations.

Running Apple Privacy Manifest as an Indie Developer — Catching Dependency Drift with Claude Code

Apple Privacy Manifest (PrivacyInfo.xcprivacy) is a quietly painful area for indie iOS developers. Drawing on twelve years of running iOS apps with over 50 million combined downloads, this article walks through how I use Claude Code to detect drift, respond to rejections, and bake the whole flow into CI.

Letting Claude Code Handle Dependency Upgrades — A Verification Loop That Catches Breaking Changes

Once a solo project carries 30+ dependencies, the monthly upgrade run becomes a dreaded ritual. This article maps out where Claude Code can take the wheel, where humans must keep judgment, and the verification loop I use to keep breaking changes out of production.
