What happened
According to multiple user claims, Anthropic's Claude Code and/or Opus 5.5 model are blocking attempts at innocuous reverse-engineering, including but not limited to those using the popular Reverse Engineer Anything REA tool. This issue may be linked to a new rule that instructs the model to avoid recreating a specific existing game. The updated rule appears to be a move to limit a flood of AI-cracked and cloned titles, with some game devs even recently being hit by extortion scams that threaten to clone their game demos into complete games before they have a chance to finish and release the original.
The issue was first reported by multiple users on GitHub, where Claude Code's issues are seeing an influx of complaints about refusals to do standard game work halfway through development, when replicating a game mechanic, and patching a tabletop-like game.
At least one of the reports is from a bona fide developer with a real track record, suggesting that the issue is not limited to malicious users.

The rule text, which is allegedly instructing the model to avoid recreating a specific existing game, is not officially confirmed, but it's plausible enough given the very clear refusals that devs have been encountering over the past week.

Why it matters
This development highlights the challenges of balancing and accessibility. While the new rule may help prevent malicious activities, it also affects legitimate developers who rely on AI tools for their work. The situation is further complicated by the varying types of reports and the lack of official confirmation regarding the rule text.
