Regenerate and edit messages in DeepSeek Harness Desktop. Adds actions after the native branch button, uses the host's validated V4 context-replacement protocol, and hides replaced rounds in chat without deleting the event history.
Release: 0.2.0 · Verified host: DSH 0.2.0-rc.2 on Windows · Runtime: Node 24+ · License: MIT
This is an independent community plugin, not an official DeepSeek release. Native macOS/Linux UI and other Harness versions have not been verified. Exact optional DSH peers declare the tested contract without installing another copy of the host.
| Target | Regenerate | Edit |
|---|---|---|
| User message | Re-run its original text prompt | Read the original Markdown, save the changed prompt, then regenerate |
| Assistant reply | Re-run the round's original prompt | Replace only this reply in context; do not send another model request |
Wait until all tasks are idle. Open the existing Desktop app → Plugins → Add plugin, and provide the absolute path to dsh-resend-0.2.0.tgz. If your manager cannot resolve a local tarball, use the unpacked package directory or the bundled Desktop CLI below. Keep the local archive at a durable path: a profile may retain its file dependency.
From a terminal, use the Desktop installation's own dsh command, made available through the native application menu's command management:
dsh plugin --profile desktop add "<absolute-path-to-dsh-resend-0.2.0.tgz>"
Do not substitute an unrelated npm-installed dsh command: the desktop profile is owned by Electron and the generic CLI can reject desktop management. A successful supported install adds both the dependency and the bundle entry; merely copying files or adding a bundle name is insufficient. Verify that the plugin is enabled and that both message action rows appear.
No build or installation scripts are needed when installing the archive. Do not start a Web/Vite server to make it work. If activation requires restarting the application, do that only after tasks have finished; refreshing a running renderer can interrupt them.
Do not install a second copy beside an existing dsh-resend row. Save a backup of the plugin and profile, remove the old package through the plugin manager at an idle point, then install this archive. Early development copies leaked their HTTP route on unload. If you see a duplicate-route error, fully exit the app at an agreed idle point and start it normally; this public package deliberately does not seize another registered route or perform an automatic restart.
Use Desktop's plugin manager or the bundled command:
dsh plugin --profile desktop remove dsh-resend
This removes the plugin, not the conversation history. Already-saved context edits remain in session history; uninstalling does not undo them. The unmodified original transcript may become visible again when the display layer is removed.
The endpoint prefix is /api/plugins/resend; normal operations are POST-only. status loads the real host's validators and reports protocol version 2, session format 4, and validation status. inspect returns canonical text without mutation. marks returns exact provenance for presentation. An unknown inspect endpoint means an old host half is still loaded; the client refuses to mutate through it.
Diagnostic output is best-effort and never written to the immutable installed package. The default is $DSH_HOME/logs/dsh-resend/breadcrumbs.jsonl; without DSH_HOME it uses $DSH_PROFILE_DIR/logs/dsh-resend/ when available, otherwise ~/.dsh/logs/dsh-resend/. DSH_RESEND_BREADCRUMB can select a complete file path; an explicitly empty value disables logging. The file is bounded to 256 KiB (old diagnostics may be discarded), and oversize payloads are truncated. Treat diagnostic exports as potentially sensitive; inspect them before sharing. No diagnostic logs, profile snapshots, personal paths, session fixtures, or repair scripts are shipped in the archive.
If the Trajectory tab is missing, first check Settings → General → Show code work views (ui-settings.config.enabled in the verified build). This plugin does not change that preference, restore other plugins, or require dsh-desktop-context.
The archive contains ready-to-run host JavaScript and the classic-script client; no compiler is needed. Full tests are in the source release, not the runtime archive.
pnpm install --ignore-scripts
pnpm check
pnpm test
pnpm test:client
$env:DSH_TEST_RUNTIME_ROOT = '<verified-readable-DSH-runtime-directory>'
pnpm test:runtime
pnpm test:all
pnpm pack --pack-destination ../../dist
The runtime path must point at a readable DSH root containing its node_modules, not an ASAR virtual directory. If using an extracted mirror, compare relevant files with the current archive first. Runtime tests use detached sessions and isolated diagnostics; they never search or rewrite your real session store.
The public release removes development-only route takeover and on-disk session-repair utilities. It keeps explicit ctx.effect route ownership, exact surface-span validation, runtime fail-closed checks, concurrency protection, and bounded waits. See design notes for the safety boundaries.
