Open-Source

TL;DR I run 3-5 parallel Claude Code sessions against the same homelab. One tab mid-refactor, one tab doing docs, one tab chasing a bug. They don’t know about each other, so every so often one tab “tidies up” a file another tab is actively editing — and Claude, being a dutiful little overwriter, just clobbers the work. I built a small Go binary that hooks into SessionStart / SessionEnd / PreToolUse, tracks file claims on disk, and injects a warning straight into the LLM’s context window when it’s about to step on another session’s toes. Optional Slack mirror so I can watch the timeline from my phone. MIT, single binary, no runtime deps. Repo: github.com/zolty-mat/claude-session-guard. ...

TL;DR Someone leaked the Claude Code source on GitHub. OpenClaw, the open-source AI coding agent with 346k stars, solves the same problem with a completely different architecture. I compared both codebases at the structural level. The verdict: these are independent implementations that converge on the same tool-use patterns because that is what the problem demands — not because one copied the other. Background In late March 2026, a repository appeared on GitHub containing what appears to be the full source code for Anthropic’s Claude Code — the terminal-based AI coding agent I wrote about switching to last month. The repo has two commits (“init” and “add readme”), 1,932 files, and weighs 43MB. ...
