Plugins can now trigger manual conversation compaction with custom instructions

What

A new compactConversation method lets a plugin ask Claude Code to compact (summarize and shrink) the current conversation, supplying its own custom instructions for how to do it. It's blocked for thin-client and remote sessions and while a turn is already in progress, and requests made this way are tagged with trigger: "plugin" for telemetry.

Why

This gives plugin authors a way to proactively manage conversation length instead of waiting for automatic compaction, while the guardrails and tagging keep it from interfering with active turns or unsupported session types.
