A developer leaked Anthropic’s real .claude folder containing 33 skills, a verifier subagent, and a seven-file harness. After integrating it locally, Claude stopped generating pointless tests and redundant confirmation prompts. The entire setup is now on GitHub with a one-line install script.

A new free Claude skill called Ponytail just reached 58,000 GitHub stars and 2,900 forks in one week. It reportedly cuts generated code by 54%, lowers cost by 20%, and boosts speed by 27% when integrated into Claude Code.

A new free Claude skill on GitHub hit 58,000 stars and 2.9k forks in a week by optimizing Claude Code to use 90% fewer tokens. It produces 54% less code, runs 27% faster, and costs 20% less, letting you swap it into your Claude workflow immediately.

Starting June 18, 2026, actions/checkout v7 will refuse to fetch code from forked pull requests in pull_request_target and workflow_run events by default, blocking common pwn request attack patterns. This update prevents untrusted fork code from running with full workflow privileges, and applies to all maintained versions by July 16, 2026, unless the “allow-unsafe-pr-checkout” flag is set.

Google has made its internal code review guides public on GitHub. One guide covers reviewers, another covers authors and defines terms like LGTM and CL. The repository shows how Google standardizes its code review process.

This article explains how Andrej Karpathy’s simple CLAUDE.md file—just four rules for AI coding agents—sparked a huge surge on GitHub by curbing overconfident, over-engineered AI edits. It shows that the real bottleneck in AI-assisted development isn’t code generation but discipline and predictable behavior.

This tweet notes that while CLAUDE.md solves the instruction-handling side, you still need to track your model’s context budget. It links to Headroom, a simple one-line-install status bar that shows your current context usage percentage in your editor’s status line.
