No genuine security threat — blog post on using Claude Code for a game-dev demo
First seen Aug 6, 2026 · Updated Aug 6, 2026
This is a personal blog post by Simon Willison describing a fun experiment where he used Claude ('Fable 5', via Claude Code for web) to autonomously build a browser game called 'Raccoon Heist' from an old GPT-3/DALL-E tweet, and documenting his workflow for previewing work-in-progress using GitHub Pages. There is no security vulnerability, attack, or malicious agent behavior described in this content.
Technical Analysis
The article walks through a benign coding workflow: giving an AI coding agent a creative prompt, having it commit code to a GitHub branch, and using GitHub Pages to preview the deployed static site. No prompt injection, tool poisoning, credential exposure, unsafe automation, or cross-agent trust boundary issue is present in the described process. The only 'agent' behavior discussed is a single coding assistant building a game as instructed by its human operator, with no adversarial input or untrusted data source involved.
