Third-party sessions start in default mode; image reads capped at 128 MB
Claude -p and Agent SDK sessions with no permission mode now start in default mode on third-party providers with telemetry off or on a fresh install, and fork subagents are on by default across the CLI, Agent SDK, desktop app, and VS Code. The Read tool no longer loads image files of any size into memory and refuses image sources over 128 MB, and idle compaction can be toggled off from a new row in /config.
