Plugin bundle for the DeepSeek Harness (dsh): rewind the conversation to a chosen completed-turn boundary and compact one side of that boundary into a hybrid (scaffold + LLM prose) summary. The other side survives verbatim. The pre-rewind session always remains resumable by id — the discarded side is never lost.
session.rewind.intercept grant (default deny)./rewind-compact [turn] [after|before] — fast path; no arguments points at the picker.rewind_compact(point, mode, rewind) — compaction ungated; rewind requires user approval (fails closed headless).rewind-compact — when to propose, tool rules, summary format, post-fork etiquette.dsh plugin --profile <name> add <path-to-this-repo>
(Or the equivalent pnpm route the profile uses; see dsh plugin --help.)
| Surface | Where it works |
|---|---|
| Esc-Esc rewind picker modes | TUI profile (decision-event seam tui/rewind-prompt / tui/rewind-done; needs the session.rewind.intercept grant — see TESTING.md) |
/rewind-compact command | TUI profile (harness command seam, composed into every human-command adapter) |
rewind_compact tool | every profile that loads the bundle (model-invoked) |
rewind-compact skill | every profile that loads the bundle (model-invoked) |
Headless/sdk: the tool's compact path works ungated; the rewind path fails closed (no direct human input in a goal-round turn).
applied: false with a note (the fork path still summarizes, scaffold-only).<original> (rewound) is passed as a create option; builds whose agent factory ignores it keep the default title (logged)._no-cwd session bucket instead of the source's workspace bucket (the TUI attaches the fork to the workspace in a separate step this bundle does not call yet); the child is complete and resumable, just ungrouped in the sidebar.scripts/e2e-web-test.py (see TESTING.md) — new session → two turns → /rewind-compact → answer both dialogs → completion message, with the child log checked on disk for the seeded history plus the five-field scaffold.ctx.compaction.compactRegion(start, end, agent, signal) (CompactionEngine contract, dsh-compaction-basic). Its signature takes no instructions argument, so the five-field scaffold is delivered inside the compacted range as its final message: the summarizer (summarizeWithLlm) appends its own instruction and condenses the range, preserving the scaffold's facts into the prose (hybrid summary, R5). For forks, the range compaction runs on the child session after seeding — the pre-rewind session is never appended to or truncated. Fallback: scaffold-only summary message when child-side compaction is unavailable.@deepseek-harness-tui/dsh-tui/lib/types/dsh-adapter/channel/session-rewind.js): cancel agent → wait turn/end → settleCompaction → walk back to enclosing turn/start, cut at turnStart.seq - 1 → agents.create({sessionId: SessionId(randomUUID()), seed, inheritedCount, parentSession, setup: clear inbox + compact discarded side in the child}). Never sessions.fork(); never mutate the pre-rewind session.ctx.tools.register(defineTool({name, description, parameters, output: {schema, render}, execute, presentCall})), defineTool from @deepseek-ai/dsh-tools, schemastery parameter specs, per-property parameter map (the dsh-tool-goal dialect).ctx.commands.register({name: 'rewind-compact', description, handler}); handler receives {rawInput, agent, signal, commandId} and returns {kind, text} (the dsh-command-compact shape; the adapter renders the leading slash).ctx.skills.register({name, description, invocation: {modelInvocable, userInvocable}, path}) (dsh-skill runtime seam; SKILL_NAME-valid name, non-empty description required).ctx.on: tui/rewind-prompt (answer: {modes: [{id, label, description}]} — rendered in the confirm pane's choice list) and tui/rewind-done (post-fork payload carries mode, boundarySeq, sourceSessionId, childSessionId; the bundle replays and compacts the discarded side in the child and returns the toast string).
