I Sell Memory APIs. I'm Also Building the Benchmark. Here's How I'm Trying Not to Rig It.
8+ min ago (795+ words) Hey everyone. This time I'll go through what got me started on this benchmark, and the core of how it's actually built. All numbers below are from the current build. Nothing is final yet, so some of them will have…...
I made two AIs review each other's code for 30 days. A human still caught the bug in 5 minutes.
44+ min ago (905+ words) Last month I let AI write 100% of my code for 30 days. The single loudest lesson wasn't "AI is amazing" or "AI is useless." It was one sentence: the thing that writes the code can never be the thing that reviews…...
Record why an approach was rejected—and when to revisit it
39+ min ago (564+ words) Disclosure: I maintain Selvedge, an open-source decision-history tool. This article was prepared with AI assistance from Grok and Codex. The example below is hypothetical and uses plain Markdown; it does not require a particular product. A repository can show what…...
AI Agent Memory: Sliding Windows, Summaries, and Vector Storage
1+ hour, 14+ min ago (623+ words) The agent we built in Post #4 has one big problem — the moment the script ends, it forgets everything. Next time you run it, it starts from zero. No memory of past conversations, no retained facts, nothing. For a quick experiment…...
The more aggressive matmul kernel lost to the register budget
47+ min ago (171+ words) The WebGPU matmul sweep started with a naive kernel, then added 16 by 16 workgroup tiling and a 4 by 4 output block per thread. At a 2048 cubed matrix size, the measured time moved from 47.24 ms for the naive kernel to 17.23 ms for tiling…...
Your Own Agent Roadmap — From Safety Net to Autonomous Discovery
58+ min ago (564+ words) The state where memory (Chapter 3), hook gates (Chapter 4), and the auditor (Chapter 6) are in place. The AI hasn't become more capable — what's been built is an environment where it's hard to be wrong. Graduation criteria: the recurrence rate of the…...
AI Safety and Alignment: Building Trustworthy Agents That Do Not Fail You

🐢 and 🐇 in My Claude Code Status Line: Now Watching Fable
1+ hour, 29+ min ago (491+ words) My Claude Code status line races a tortoise against a hare to show whether I'm burning quota faster than a steady pace. Last time I switched the main bar to the 7-day window. The status line wasn't wrong. It was…...

From SkillCheck to TraceMantle: Tracking Agent Skill Changes and Test Evidence
1+ hour, 55+ min ago (637+ words) I’ve renamed SkillCheck to TraceMantle and expanded its scope. The original project focused mainly on validating AI agent skill files. TraceMantle retains that functionality and adds support for tracking the files in a skill package, comparing changes, and checking whether…...
