The Two-Corrections Rule: When to Stop Fixing Your Agent and Fix the System

Most developers overcorrect their AI agent in-session when it keeps making the same mistake. The two-corrections rule is a decision boundary: if you've corrected Claude Code twice on the same issue and it persists, stop correcting the session. The problem is upstream, in CLAUDE.md, the spec, or the codebase itself. Fix it there, start fresh, and the mistake never comes back.

Sandcastle: Running Claude Code Agents in Isolated Sandboxes

Matt Pocock just shipped Sandcastle, a TypeScript library that runs AI coding agents inside isolated Docker, Podman, or Vercel sandboxes and merges their commits back through git worktrees. It removes the biggest blocker to unattended agentic workflows: letting Claude Code touch your repo without supervising every change.

React Native BLE in Production: What Nobody Tells You

After a year with react-native-ble-manager on a production app, here's what the library documentation doesn't cover: the Android 12 permission split, the reconnection myth, the behavioral differences between iOS and Android, and the architecture that keeps it all manageable.

Skills vs MCPs: Stop Burning Your Context Window

Most Claude Code users install MCPs for everything without realizing each server front-loads thousands of tokens before the session begins. Skills (plain Markdown files in .claude/skills/) load on demand and cost nothing until called. Understanding the skills vs MCP trade-off is one of the highest-leverage optimizations in an agentic coding setup.

Claude Code's 1M Context Window Is Live. Here's What Actually Changed.

Anthropic made the 1 million token context window available to all Claude Code users on March 13, at no extra charge. Three weeks in: compaction friction is down, the pricing model beats OpenAI's at scale, but context rot is real and the fundamentals of session design haven't changed. The 1M window is headroom, not a replacement for structured context.
