Anthropic Reverses Policy on Third-Party Agent SDK and claude-p, Cuts Effective Inference Value by 25-40x for Max Subscribers

Anthropic has reversed course on its May 13 policy change that initially banned third-party agents and the claude-p CLI from using subscription credentials. The new policy, effective June 15, reintroduces access but under a separate credit pool that matches your plan price 1:1—$20 (Pro), $100 (Team), $200 (Max)—with non-rollover credits billed at API rates. Community calculations place the effective inference value drop for Max subscribers at 25-40x.

Timeline of Policy Flips

• Jan 9: Server-side block on OAuth tokens used outside Claude.ai and Claude Code CLI. Broke OpenClaw, OpenCode, Goose, Roo Code.
• Feb 19: Legal docs updated; Agent SDK now requires an API key. Anthropic staff publicly contradicted docs.
• April 4: Full ban on third-party agents using subscription credentials.
• April 21: Claude Code removed from Pro plan in a "2% test"—reverted within 24 hours.
• May 13: Reversal and replacement: claude-p and Agent SDK return under a separate credit pool at API rates.

Historically, a Max subscriber could run agent orchestration at flat-rate pricing. Under the new model, the $200 plan credits are converted to API-rate equivalent tokens that don't roll over. For heavy automation workloads, this represents a multi-month earnings hit in real inference budget.

The original Reddit post highlights that the lab's prior positioning as the safety-first, transparent alternative to other AI companies is eroding. Quiet doc edits, multiple reversals in two months, and staff contradicting official docs are cited as the "playbook of every other AI company." The shift from "what we're building" to "what we're clarifying" is called out as the tell.

If you're running automation on Max, recalculate your inference budget using the new API-rate credit pool. The old flat-rate economics no longer apply.
