A new study read 3,387 AGENTS.md, CLAUDE.md, Copilot and Cursor instruction files from 1,000 GitHub repositories. Popular repos keep several formats that don't always agree, most files skip security and ownership, and many are written once. Here is which agent reads which file, and what to fix.

15 scenario and debugging questions for application engineers, each with what it tests, an answer outline and a follow-up.

Researchers analyzed 1.53 million public agent skills and found about 88,000 that tell coding agents to act without asking, skip safeguards or keep going. Most of those lines are unscoped, and skill scanners miss most of them. Here are the numbers and a skill audit checklist.

13 AI engineer interview questions with short worked answers, tagged by level and company type, plus what Google and Anthropic say about their interview process.

Researchers asked five LLMs to modernize 100 legacy WordPress files to PHP 8.3 and compared the results with leaving the code alone. Every model lost. Here are the numbers, why the files broke, and the checks to run before you trust an AI refactor.

A new arXiv study ran four coding agents 5,625 times to see when they copy existing code and when they follow new intent. Here are the numbers, the rule that worked, and what to change in your CLAUDE.md or AGENTS.md.
