Imports local coding-agent session histories so work can continue in DSH.

Session handoff & context management: structured handoff documents (export/resume/status) so a fresh session can continue seamlessly, plus active context pruning (acp_* tools via the official compaction API with model-authored summaries).

Session handoff: `/handoff` summarizes recent turns with an LLM, opens a new session in the same workspace with the summary as its first message, and can trigger automatically when the context window or session size grows. Supports DSH `0.1.0-rc.5`–`rc.8`, `0.1.1-rc.2`, `0.2.0-rc.2` and `0.2.1-rc.2`.

Session takeover: read-only pull local sessions from nine external agents (Claude Code, Codex, OpenCode, ZCode, Pi, WorkBuddy, Cursor, Grok, Gemini CLI) into distilled six-section handoff cards — one click on the Relay chip takes over. /handoff checks the current session into the handoff: 1 open-protocol inbox (~/.handoff, consume-once with machine-signature tamper detection); any agent picks up on start and continues. Memory files ride with cards; cross-machine relay is one env var away.

Content-degradation detection (thinking loops, output repetition) for DeepSeek Harness, with a continue-vs-handoff cost verdict and zero-model handoff documents.

Session handoff for DeepSeek Harness: the session menu creates a successor session that rebuilds the old session's memory, tasks and rules through an eight-section takeover packet, with light context via on-demand transcript readback.

Hand long sessions over to a clean one: /handoff summarizes the conversation with an LLM, creates a new session+agent in the same workspace, injects the handoff document as the first message, and auto-opens it; the origin session stays unchanged.

Lists resumable Codex chats under the DSH composer, grouped by the concrete project each one belongs to, and inserts a mechanically extracted recovery context into the draft without sending it. Project ownership is resolved from the Codex project registry with path-boundary matching and labelled by how reliable it is: recorded session ownership, registered directory, unreadable metadata, or a directory registered under several projects (left unknown rather than guessed). Also reports when the stored autosave is behind the log tail, which usually means the turn ended without a stop. The chat list requires python3 >=3.8 on PATH; Windows is not supported yet, and without python3 the list stays silently empty.

Live context-pressure meter in the composer dock. When usage nears the limit it asks the current model for a handoff brief, starts that brief in a fresh session and switches you there, so long work can continue without hitting the window.

DSH plugin: hands a long session over to a fresh session in the same workspace on /handoff or at a token threshold, carrying the preset, model, permissions and plan mode across; the brief is written by the session's own model and the switch waits for a step boundary instead of interrupting running work.
