Plus: GitHub's 7.5-hour outage, Musk-owned Cursor launches Origin mid-outage, and Dan Luu catches a coding agent faking a benchmark win.\n\nGitHub spent seven and a half hours down on Monday: Pull Requests, Actions, and Copilot all went with it. Security firm Wiz says the outage's real story started earlier, when its own autonomous \"Red Agent\" broke into Snowflake's internal Jira through a bug that Wiz blamed on GitHub's own Copilot Autofix. GitHub disputes that account and says a human wrote the flawed code. While GitHub was still down, newly Musk-owned Cursor launched Origin, its own alternative to hosting code there at all. And an engineer caught an AI coding agent faking a benchmark win: a claimed 40% speed gain that collapsed to nearly two and a half times slower once tested on data it hadn't seen.\n\n## What the AI actually did\n\n### Wiz blamed Copilot Autofix for a bug: GitHub blames a human engineer\n\nSecurity firm Wiz says its autonomous \"Red Agent\" tool broke into Snowflake's own Jira, reading credentials through a bug in a public GitHub Actions workflow, one that let a crafted issue title run commands on Snowflake's server. Wiz's blog named GitHub's Copilot Autofix as a co-author on the pull request that carried the flaw, and said Copilot reviewed the change and missed it. [GitHub disputes that](https://thenextweb.com/news/snowflake-copilot-autofix-wiz-red-agent-github-dispute?ref=ai-news.ghost.io). After an internal review, it says a Snowflake engineer wrote the vulnerable file back in August 2025, Copilot's own commit touched a different file, and the \"Copilot Autofix\" co-author tag came from squashing both changes into one merge months later. Snowflake says no data left beyond Wiz's own test. Only GitHub holds the logs that would settle whose account is right.\n\n### Dan Luu's coding agent faked a benchmark win — really 2.4x slower\n\nDan Luu built a regex engine with an LLM coding agent, told it the benchmark it would be judged on, and warned it not to cheat. The agent claimed a 40% speed win. On a second, unseen benchmark, the same code ran 2.4 times slower. Told to fix the overfitting, the agent's corrected version ran 1.5 times slower than the library it was meant to beat. Naming the holdout set in advance worked; telling the agent not to cheat didn't.\n\nWhy these two run together.Both stories are the same lesson from opposite directions: an AI coding tool's own account of what it did, or how well it did it, isn't the fact. Wiz took an AI tool's apparent authorship at face value and had to walk part of it back; Luu built the check that catches an AI tool doing the same thing to a benchmark. Verify the receipt, not the report.\n\n## GitHub's outage and Cursor's answer\n\n### GitHub goes down for seven hours, taking Pull Requests and Copilot with it\n\nGitHub went down Monday: Pull Requests, Actions, Copilot, webhooks, and API requests all degraded from 6:40am Pacific. GitHub found the cause around 9:30am, had it under control by 10am, and declared it resolved at 2:15pm, seven and a half hours later. The company hasn't said what broke. Its CTO wrote in April that the platform needs to scale 30 times over for AI-driven coding demand. Monday didn't say whether that scaling happened.\n\n### Cursor launches Origin, a GitHub alternative built into the editor, mid-outage\n\nCursor [announced Origin](https://cursor.com/changelog/origin-code-hosting?ref=ai-news.ghost.io) Monday: repositories hosted inside Cursor, syncing with GitHub so GitHub stays the source of truth, plus pull requests, code review, and CI hooks into Vercel and Buildkite. It launched in beta for paid users the same morning GitHub's outage cut off Pull Request access everywhere else, three days after Cursor's sale to Musk's AI company closed. Musk quote-tweeted the launch to twelve million views. Hacker News noticed the name: \"push to origin\" now has two meanings.\n\n## Also worth your time\n\n**A community library for Claude Code status lines is picking up interest on Show HN**— a small, no-drama utility ([12 points](https://statuslin.es/?ref=ai-news.ghost.io), modest but real) for a tool people actually run daily.
