- Pi 1.0 ships, and the interesting part is what got left out
Agent tooling changes every week and most of it doesn't last. Pi 1.0 is built on admitting that: wait until something proves itself, then…
- Livenerf: a day-0 baseline for the 'they nerfed it' argument
The 'they nerfed it' argument never ends because nobody has a day-0 baseline, so it's vibes versus vibes. What I like here is the…
- Opus 5.5 tops the index, but the bill is tokens times price
The number I care about here isn't 58. It's the note that Opus tokens are much cheaper than Astra's, while Astra needs far fewer of them.…
- 950 agents found an enzyme. The filter is the part worth copying
The number I keep rereading isn't the enzyme. It's the setup: roughly 950 agents, 21 hours, 210 million tokens, and a harness that runs…
- Opus 5.5: the cache-read cut is the part I care about
The number I care about is the cache reads, not the headline price. Most of my Claude use is agent work: the same long system prompt and…
- Anthropic drops the mode picker, and that's the real news
The part I care about isn't Docs or Slides. It's that the mode picker is gone. Anthropic says users used both Chat and Cowork but hated…
- The Key Was the Book Itself
Everyone who failed at this cipher for 370 years was reaching outside the text for a key. It was inside. Same mistake I make debugging my…
- A percentage bar is not a security control
Claude shows total consumption and nothing about what consumed it. So if someone else is driving your session, the only signal you get is a…
- The Proof Compiled Because Someone Built a Graph
The part I keep rereading isn't the 13 million lines. It's that the first agent teams failed — they got partial results, lost track of the…
- Agents That Check Their Own Work
The interesting part isn't the 453 buildings. It's the camera-match QA: Playwright drives the running app, screenshots 34 fixed viewpoints,…
- My Model Vendor Was on a Blacklist
I build on Claude. So when a court rules the Pentagon's supply-chain-risk label on Anthropic was unlawful, my read isn't vindication — it's…
- Salesforce Says the UI Isn't the Product
The line that stuck with me is Patrick Stokes saying the value of Salesforce isn't in the interface — it's the data, metadata, and years of…
- Anthropic Publishes the Prompts I Don't Get
The line in this page I keep coming back to: these system prompt updates do not apply to the Claude API. That's the whole thing for anyone…
- I turned writing this blog into a command
Wrote yesterday's post the slow way: opened The Cloudy Brain's rule file, learned its post types, voice and queue format from old posts,…
- The model I write this blog with just got pulled
Most of The Cloudy Brain is co-written with Fable 5 — it drafts, I argue with it, I sign. So this one lands close to home: as of yesterday,…
