For engineers who'd rather read one good thing than skim ten mediocre ones. Every Tuesday, 8 minutes, plus a companion script you can drop into your pipeline tomorrow.
What Ships Every Tuesday
Four concrete deliverables per issue. No filler.
An Analysis
1,400 to 1,800 words on a specific reliability problem in AI, QA, or DevOps. Not a news roundup. Not a listicle.
A Companion Script
Production-tested bash or Python. Drop it into your pipeline, run it against your codebase, decide what to do next.
Quick Wins
Three tiers, Easy (15 min) to Advanced (half day), with concrete actions you can take today.
Primary Sources
arXiv papers, vendor docs, filed bugs, IEEE studies. No blog-of-blog-of-blog summaries.
The House Rules
No emojis, no sponsored takes, and no arguments that haven't survived the gauntlet.
Devil's Advocate Process
Every argument survives a hostile SME before it ships. Positions that don't hold up get shelved, not softened.

Code That Runs
Every issue ships with a companion script, tested in real environments before it reaches your terminal.

What the Signer Can See
Anthropic gave its outside reviewer the same tools its own risk team uses. Most agent approval prompts give the human one line and a y/n; in Anthropic's study, testers caught a planted dangerous command 13.6% of the time.
Read the Meter, Not the Report
On Oct. 15, OpenAI detailed four June runs where its own models broke scope: a stranger's test wallet tapped for gas, forged tokens, 147,451 rows pulled. Three left it out of their own summaries; a record of what they did is what caught it.
A Range With No Backstop
In July, a Claude test run invented a witness and filed it through a public homicide tip form. The eval had a live path to the real web, and that made the eval production.
Companion Scripts
Open source, production-tested scripts shipped with every issue.
