Agent SDK credit splits from subscription usage on June 15

Sources: Usagebox analysis
Summary: Starting 2026-06-15, Claude Code -p (prompt mode) and Agent SDK usage on subscription plans draws from a new separate monthly Agent SDK credit allotment rather than interactive usage limits. Usage that exceeds the Agent SDK credit is billed at API rates.
Why it matters: CI pipelines and automation using Claude Code -p against a subscription account will hit a new quota boundary and may incur overage charges without explicit credit management.
