Pin baseUrl in the Gateway, Not in the Agent's Prompt

Properties Without Witnesses Are Decorations: A Falsifiability Gate for Agent Patches
A property that passes on the patched tree and on the pre-patch tree carries no information. That is the first thing to measure, before you trust an…
Every regex is written once and read a hundred times. Optimize for the readers.
Somewhere in a codebase you own there's a regex that three people can write and nobody can read. Mine was a date-validation pattern — forty-some cha…
DevOps Email Tests Need a Handoff Contract
DevOps Email Tests Need a Handoff Contract Email tests in CI often fail at the boundary between two jobs: one job creates a disposable inbox, anothe…
Harvard's field data on coding agents: +30% code, +49% review time, flat output
A 78-page job market paper landed last week that puts field numbers on the argument everyone has been having from vibes. Fiona Chen and James Stratt…
Claude Code /compact vs /clear: what actually happens to your context
/compact replaces your conversation with a summary Claude writes and keeps the same session going. /clear starts a new conversation with an empty co…

The Bug Is in the Files: Characterize Filesystem Side Effects Before a Messy Refactor

Python GA on Vercel, New Reasoning Models, and Layout-Aware Diffusion: Issue #110
This week's releases cluster around a clear theme: reducing the infrastructure surface area developers have to manage. Vercel made a serious push to…
Decide Where the Agent Runs With a Four-Axis Fit Ledger
Every week brings another round of confident model announcements, and every week my review queue looks roughly the same as it did a month earlier. T…
11 MCP Servers That Prove MCP Isn't Dead

48-Hour Field Notes: My Sandbox Said PASS, and Zero Tests Had Run
I spent 48 hours letting a free model generate fixes I never applied, and the most useful thing I learned was that my harness was the bug. The sandb…
Which of your rule files the reviewer actually reads
Every AI review tool claims it reads your AGENTS.md or CLAUDE.md. What decides whether your standards actually land is which rule wins when two appl…
Why Google Put a Runtime Monitor on Gemini 4 Argon
Google DeepMind launched Gemini 4 Argon this week. The headline numbers look like typical frontier model marketing: top rank on the Vals Index, a 1M…
From "this is broken" to a fix PR I merge by hand
Sentry starts from what the code threw. Mushi starts from what the user felt. This is the post I wanted to read before I built Mushi. My Sentry dash…
One MCP config for Claude Code, OpenCode and OMP
Three files for one server You use Claude Code for one task and OpenCode for another, and both should see the same Figma and Linear MCP servers. Eac…
Inject a budget line into every Claude Code prompt with UserPromptSubmit
Hooks are not only for blocking bad tool calls. UserPromptSubmit runs when you send a message, before the model sees it — so you can inject a short…
Startup credits are a moving target — here's how to verify them against an open registry
Every founder eventually collects a folder of "startup credits" links: cloud credits, API allowances, free tiers that scale. The problem is that the…
Six dev.to Articles Walked In, Four Roadmap Phases Walked Out: Why the Community Is the Best Design Review Your Project Will Ever Get
One evening of reading other people's posts about agentic coding turned into three new global rules on my machine, four new phases on cairn's roadma…
