How Mozilla Uses Claude Mythos to find Firefox bugs before hackers do

How I AI Podcast

Custom harness using Claude Agent SDK and Anthropic Mythos with LLM-based file scoring and a verifier subagent to find and fix over 500 Firefox security bugs in April 2026.

  • LLM judge prompt evaluates each of Firefox’s C++/IPDL/WebIDL files with two numerical scores—memory-safety vulnerability likelihood and web-accessibility likelihood—to prioritize scanning across tens of thousands of files.
  • Analyzer agent via the Claude Agent SDK performs up to 14 hypothesis loops per target, generates HTML proof-of-concept test cases, and invokes a fuzzing build instrumented with AddressSanitizer and RLBox to detect use-after-free and memory-safety issues.
  • Verifier subagent inspects agent-generated crash reports for false positives (e.g., test-only preferences or self-introduced bugs), achieving near-zero false positives and producing structured JSON bug reports that mobilized ~100 engineers.

How the most AI-pilled product team builds products | Fiona Fung (Claude Code and Cowork)

Lennys Podcast

Fiona Fung explains how her Claude Code and Cowork teams at Anthropic use Claude Routines and cloud code remote sessions to automate manager tasks—summarizing feedback, generating pull requests, and verifying against in-repo specs—enabling engineers to ship eight times more code per quarter.

  • Anthropic engineers ship eight times as much code per quarter in 2026 compared to 2021–2025, according to an internal AnthropicAI X.com status update.
  • Fiona schedules a daily Claude Routine to scan all Slack feedback channels and emails, output theme summaries by morning, and auto-create PRs for bug fixes and polish.
  • The team uses AI-driven code reviews via Claude Code Reviews against checked-in spec files and AI-generated tests (TDD), automating test creation and validation before human review.

Full Tutorial: Make Professional Launch Videos for Free with Hyperframes | Bin Liu & Jake Moran

Peter Yang

Use HeyGen’s open-source HyperFrames framework with AI coding agents (e.g., Cloud Code + Fable 5) to convert any website URL (such as spotify.com) into a professional launch video by generating an HTML/CSS/JavaScript codebase and rendering it to MP4 for free.

  • A 1-minute Spotify launch video was generated end-to-end by prompting Cloud Code with Fable 5 using the “/website-to-video” HyperFrames skill on spotify.com (“make a launch video for spotify.com”).
  • HyperFrames installs via the quickstart script at hyperframes.ai.com/quickstart, as the “HyperFrames by HeyGen” plugin in the Codex Plugin Store (Creativity section), or as a connector in Claude, enabling slash-command video generation.
  • Jake Moran’s 5-step playbook—dropping a frame.md (via hyperframes.dev/design) for brand aesthetic, creating a storyboard.md, reusing animations from the launch-video repo, generating static frames for review, then building and polishing in HyperFrames Studio—allows each video to be produced within a day of launch.

clem 🤗 – Co-founder & CEO @HuggingFace argues that leading in open-source AI first—as the US did from 2016–2024—is the essential foundation for any nation or company to accelerate innovation, talent, and ecosystem growth and ultimately dominate in general AI.

Udi Menkes argues that while human experts build judgment by observing real decisions and outcomes, today’s language models merely “read” text—so in finance AI must ground its recommendations in actual entity–action–result patterns.

Garry Tan argues that as usable AGI arrives in 2026, its raw intelligence alone won’t suffice—you’ll need to build out a “personal brain” and a “company brain” loaded with your own context to truly unlock its power.
