Anthropic quietly loosens limits: third-party agents and claude -p can use Claude subscription quotas
dotey · x · 2026-10-12
Key facts
- What's confirmed: logging into Claude Code with a Claude account means all usage — daily chat, claude -p scripts, Agent SDK, and third-party tools — draws from your subscription quota. Third-party agents like Amp can use your Claude login and only consume subscription limits.
- What's unclear: no official announcement from Anthropic; this looks like Amp probing unilaterally. No public stance on whether such usage risks account bans — the official docs neither threaten bans nor guarantee safety.
- Amp author Quinn Slack cited Anthropic-affiliated accounts saying "nothing was removed this time," reading the policy update as reaffirming that Agent SDK and third-party apps may use subscription limits.
Policy timeline
- February: docs updated to restrict third-party tools from subscription login
- April 4: OpenClaw and similar agent tools cut off from subscription quota, pushed to pay-per-use; affected users refunded
- June 15 (original plan): Agent SDK and claude -p to be billed separately — suspended the same day it was announced
The author notes Anthropic's rules keep shifting and its own staff likely can't keep track. On HN, a question about bans for non-Claude Code tools went unanswered officially.
