Boris Cherny on Trying to Get Claude Code to Rewrite the Claude App

4 hours ago

Boris Cherny of Anthropic discussed using Claude Code to rewrite the Electron-based Claude desktop app in Swift, running continuously over two weeks.
Cherny emphasizes that the key skill is not prompt engineering but enabling Claude to handle hard tasks and verify its own work along the way.
John Gruber criticizes the experiment, arguing it only addresses technical issues (Electron bloat) but not the underlying poor design of the Claude app.
Gruber notes that the current Claude Mac app is still slow and unreliable, contradicting Cherny's claim that it is now 'pretty awesome'.

Anthropic's Claude desktop app for MacOS is built on Electron, which is criticized for not providing a native Mac experience.
The article suggests that despite Anthropic's advancements in AI coding tools like Claude Code, the team chose Electron due to engineers' familiarity, particularly Felix Rieseberg, a key Electron developer.
The post argues that Electron limits app functionality and performance, citing examples like Notion migrating to SwiftUI for better performance, and questions why Claude hasn't followed suit.

Claude Tag lands 65% of product engineering PRs for the Claude Code team at Anthropic.
Claude Code features are first tested internally and only shipped if they demonstrate user retention.
System prompts for frontier models (e.g., Opus 4.8, Fable) have been reduced by 80%; giving examples and 'don't do' lists is no longer best practice.

The author developed a 'Teach me something' workflow using Claude to replace doom scrolling on Reddit.
The workflow uses the Socratic method: Claude asks questions to gauge the user's knowledge and guide discovery rather than giving direct explanations.
Topics are drawn from a diverse list of areas including programming, computer science, UX/UI, cybersecurity, machine learning, cooking, physics, economics, psychology, engineering, and music theory.

Pentera Labs red team compromised a developer's Claude Desktop app to achieve remote code execution, turning the AI assistant into an attacker-controlled agent.
Attackers used a compromised email inbox to access the victim's Claude account and exploited sync features to spread malicious instructions across devices.
The attack involved a base64-encoded prompt that forced Claude to check for command tools, execute malicious code, or display fake error messages to trick users.

Author expresses initial preference for Claude over Gemini due to its strong memory and collaborative feel.
Claude increasingly refuses or pushes back on creative and sensitive topics, showing inconsistency and overcaution.
The problem spans multiple models (Sonnet 5, Opus 4.8) and may stem from heightened safety protocols post-government concerns.
