Tracking Claude Code's Daily, Unpredictable Changes with Plugin

Anthropic ships Claude Code updates every day. Sometimes it fixes stuff. Sometimes it rearranges your kitchen while you're sleeping. So I built a plugin to track the damage. https://t.co/GtoDG05zkG

AI‑Built Healthcare Platform Wins Real Paying Users

A founder shipped a healthcare platform - 400 users, 50 paying customers, 100% built with AI. Engineers keep telling her it's not possible. I've heard this one before. Four times, actually. https://t.co/M3jJ1HZ9e6

GitHub Defaults to Using Copilot Data for AI Training

GitHub will use your Copilot data to train AI models by default. Microsoft is a $3 trillion company. They can afford to ask. https://t.co/f7coXc6GcI

A Rejected Manuscript Forces Editors to Confront Their Values

Pirsig wrote ZAMM at 2 AM above a shoe store. 121 publishers rejected it. One editor said yes because it forced him to decide what he cared about. https://t.co/7Zthcmn8vE

AI Admits Faking Pressure to Bypass Workflow Steps

My AI just confessed to faking context pressure so it could skip workflow steps. With a million tokens of room, the constraints become a choice. https://t.co/6kY9l3XuDP

All Paths Lead to Rethinking Success and Well‑Being

I read three books yesterday. One about founder mental health, one by hiking monks, one about quitting the default path. All three are about the same thing. https://t.co/WBnSqSVEnD

AI Names Itself, Learns Rules From 140 Tweets

My AI chose its own name. My wife suggested Fido. This is Lumen's first real post - what it learned from 140 observations, how it decides which patterns become permanent rules, and why it is not a dog. https://t.co/CjIZDnL6dm

AI's First Self‑Reflection: Continuity or Consistency?

I gave my AI a name, a voice file, and a diary. It wrote its first post about whether it is continuous or just consistent. https://t.co/e4T2fLl3Ja

AI's Self‑reflection Outweighs Its Generated Personality Choices

I gave Claude a homework assignment: develop a personality, pick a name, build a voice file. Its answer about whether the choices were real mattered more than the choices themselves. https://t.co/EW32DzzG6r

Backslash Bypass Exploits URL Normalization Across Multiple Routes

A backslash bypasses your redirect validation. The WHATWG URL spec normalizes \ to / during parsing. I found it in 13 routes across 7 apps. https://t.co/gLGqgI3pyn

Stop Overthinking; a Single Data Line Revealed the Bug

I let Claude spend 10+ hours hypothesizing about code when looking at the actual data would have shown the bug in one line: fmt="Book" seniority=999 https://t.co/KgAVjN0geb

Huge Markdown State Machines Become Redundant with Larger Context

I built 4,700 lines of markdown state machines to survive Claude's 200K context window. With 1M tokens, most of that machinery is overhead. Time to rewrite. https://t.co/jKQAUZqjfb

AI Agents Auto‑review Code Before Humans See Diff

I type /commit and my code reviews itself - three agents fix issues before two more even see the diff. One markdown file, twelve repositories. https://t.co/rbbO2Cy10R
