Repost claims Anthropic’s Claude Opus 5 system prompt leaked in a 200,000-character dump

A repost claims Anthropic’s Claude Opus 5 system prompt has been leaked and says the prompt is about 200,000 characters long. The post argues that the new safeguards are overly paranoid and may block legitimate scientific work, while the attached image references a GitHub repository with leaked system prompts across several AI products.
Because this is a third-party claim about a leaked system prompt, the factual weight is limited here. The main value is the security and transparency angle: a purported prompt leak, criticism of the model’s safety classifiers, and renewed debate over how frontier models should balance safety with capability.
