How to stop Linux threads cleanly
Stopping a Linux thread is a surprisingly annoying affair. In this post I present common pitfalls and some solutions -- although no truly satisfactory method exists.

Show HN: Playwright Skill for Claude Code – Less context than playwright-MCP (Score: 151+ in 19 hours)

Link: https://readhacker.news/s/6DUvZ
Comments: https://readhacker.news/c/6DUvZ

I got tired of playwright-mcp eating through Claude's 200K token limit, so I built this using the new Claude Skills system. Built it with Claude Code itself.
Instead of sending accessibility tree snapshots on every action, Claude just writes Playwright code and runs it. You get back screenshots and console output. That's it.
314 lines of instructions vs a persistent MCP server. Full API docs only load if Claude needs them.
Same browser automation, way less overhead. Works as a Claude Code plugin or manual install.
Token limit issue: https://github.com/microsoft/playwright-mcp/issues/889
Claude Skills docs: https://docs.claude.com/en/docs/claude-code/skills
