Claude Code HERMES.md billing flaw (2026)

Main article: Anthropic Claude Code HERMES.md billing flaw

In April 2026, a technical flaw in Claude Code triggered by the string "HERMES.md" in git commit messages bypassed subscription plans, routing users to pay-as-you-go API rates and charging one account over $200. Anthropic refused to issue a refund, categorizing the overcharge as an un-refundable technical error.

Price crackdown against third-party tool usage (2026)

During April 3rd, 2026, Boris Cherny, head of Claude Code, posted on Twitter (now X) announcing Claude subscriptions will "no longer support third-party tools", such as OpenClaw because it puts an "outsized strain" on Anthropic's systems. The changes took effect on April 4th, and now to use third-party tools the user must pay a separate fee from subscription or use a separate Claude API key through Anthropic's developer platform. It is rumored this action was done to prevent Claude users from using tools from competitors, as OpenClaw is supported by OpenAI.
