DSH (DeepSeek Harness) Web GUI plugin: edit the last user message back into the composer after stopping a turn — no more retyping from scratch.
Why
Sending a message, stopping the reply, and wanting to re-ask with a small change currently means typing the whole prompt again. This plugin adds an "Edit last message" button to the composer tool row: it restores the tail user message text and focuses the input, ready to edit and send.
It is a client-side plugin — the conversation log stays append-only. Sending the edited text appends a new turn (the original message and the interrupted reply remain in the transcript). It never touches the host, the session log, or the agent loop.
Install
The plugin bundles as a dsh.bundle + dsh.client package. It works on any
DSH setup that loads third-party bundles (source dsh web, DSH Desktop,
custom profiles).
From npm (published — recommended)
dsh plugin --profile web add dsh-plugin-edit-message
Restart the GUI (fully quit and reopen) after installing — client plugin bundles register at startup.
DSH Desktop users: Desktop's DSH_HOME lives under
%APPDATA%\dsh-desktop\harness, so target that explicitly:
DSH_HOME="${APPDATA}/dsh-desktop/harness" \
dsh plugin --profile web add dsh-plugin-edit-message
Then quit and reopen DSH Desktop.
From GitHub or a local checkout (unpublished builds)
# GitHub repository
dsh plugin --profile web add git+https://github.com/WyxBUPT-22/dsh-plugin-edit-message.git
# local checkout (pnpm install && pnpm run build first)
dsh plugin --profile web add /path/to/dsh-plugin-edit-message
From this source checkout
The repository is self-contained: devDependencies resolve the official
harness client packages from the npm registry, so no deepseek-harness
checkout is needed.
pnpm install # pulls the official client packages from npm
pnpm run build # emits lib/index.js + lib/client.js + lib/types
dsh plugin --profile add /path/to/dsh-plugin-edit-message
dsh --profile
Uninstall with dsh plugin --profile remove dsh-plugin-edit-message.
See docs/user/develop/basic/publish.md in the harness checkout for the
dsh plugin workflow.
How it works
- Registers one client plugin (
dsh.clientmanifest,platform: web) that contributes an entry to the officialconversation.input.leftcomposer tool-row slot (a documented multi-plugin list slot — zero official changes). - The button renders only while the session is idle, a tail user/steering message exists, and that message is plain text (draft images are browser File-backed and cannot be resurrected from the durable log).
- On click:
inputActions.setDraft(text)restores the text and the composer is focused. The plugin prefersinputActions.focuswhen the deployed runtime exposes it, otherwise falls back to the composer textarea (the GUI keeps exactly one). - If you remove the plugin (
dsh plugin remove dsh-plugin-edit-message), the surface disappears entirely — the tool row reverts to official chrome.
Differences from in-transcript editing (Codex style)
In-place replacement with a rewind of the log tail is a larger design (log-truncation semantics, compaction checkpoints, session log format, dual SDK projections) and is intentionally out of scope. This plugin provides the interaction value — edit the text, resend — with zero blast radius.
Develop
pnpm run typecheck # tsc --noEmit (strict)
pnpm run test # vitest (logic matrix + component behavior)
pnpm run build # tsdown → lib/client.js + types
pnpm publish runs prepublishOnly (typecheck + test + build) first.
