dsh-input-enhancer

中文 | English

A DeepSeek Harness Web plugin that makes the chat composer better suited to long-form editing.

Features

• Lock button: registered in the official conversation.input.right slot, near the send button; a prominent red fill when locked, with a state tooltip on hover. It can also be toggled with Ctrl/Cmd+Alt+L (only while the composer is focused).
• Lock ⇔ enlarge coupling: locking enters "long-form editing mode"; unlocking restores the default size.
• Character count is independent: it shows whenever the composer is non-empty, locked or not.
• Long-text warning: once the draft reaches the threshold (800 chars by default), the count badge turns amber with a "long text" hover hint.
• Per-session state: each conversation keeps its own lock flag.

Lock state & composer

Tooltip:

• Unlocked: Unlocked: composer is normal size, Enter sends normally
• Locked: Locked and enlarged: Enter will not send. Press Enter 3 times to unlock and send

Triple-Enter (locked-state escape hatch)

While locked, to send without first unlocking: press Enter 3 times to unlock and send immediately.

• The first two Enters have no side effect (no send, no newline); they only count. The lock icon turns into the current count (1st shows "1", 2nd shows "2") with a growing pulse.
• The 3rd Enter plays a firework burst (colored particles flying out from the lock button for ~1 second), then unlocks and sends the current content.
• Timeout, any other key, or a session switch resets the count.

> Triple-tap applies only while locked; an empty composer will not send.

Draft swap (park a half-finished draft)

While the agent is still thinking or executing, you'll often want to type the next message in advance. But sometimes you realize mid-draft that this text should wait a few turns. Park it with a direction-agnostic swap button (⇄), keep writing and sending other things, and swap it back in the right turn.

• Swap button: registered in the conversation.input.right slot, just left of the lock button; the icon is ⇄ (opposing arrows, no direction bias). Clicking it swaps content between the composer and the staging slot.
• Atomic swap semantics:

- Slot empty → the composer's text moves into the slot, and the composer empties; - Slot full → the two swap: the staged draft returns to the composer, and the composer's current text moves into the slot (neither side is lost); - When the slot is full the button is highlighted, so you can tell at a glance that a draft is parked.

• Shortcut Cmd+Opt+K (macOS) / Ctrl+Alt+K (Windows/Linux) is equivalent to clicking the swap button; it only acts while the composer is focused.
• Per-session, in-memory only: each conversation has its own single slot; it is cleared on refresh or restart — it only serves the temporary "park for a few turns" case, never crossing sessions or touching disk.

> When both the composer and the slot hold text, clicking swap will exchange them; use accordingly.

Guarantees

• No composer replacement: intercepts only the keyboard submit path and overlays enlargement styles, keeping the official input state machine, command menu, queue, and attachments.
• IME-friendly: Enter during composition is never intercepted.
• Blocked while locked: plain Enter, Ctrl+Enter / Cmd+Enter, other Enter combos that reach the official submit path.
• Preserved: Shift+Enter newline, IME candidate confirmation, edit/copy/paste/attachments, and mouse-click send (the lock only guards the keyboard).

Keyboard shortcut

Ctrl+Alt+L (Windows/Linux) or Cmd+Alt+L (macOS) toggles the current composer's lock without reaching for the lock button. It only acts while the composer is focused.

> Why not Ctrl/Cmd+L: Chrome / Edge reserve Ctrl+L and macOS reserves Cmd+L for the address bar, which intercepts them first; hence Ctrl/Cmd+Alt+L.

Ctrl+Alt+K (Windows/Linux) or Cmd+Opt+K (macOS) triggers the draft swap. It only acts while the composer is focused.

> Adjacent-shortcut note: Cmd/Ctrl+Opt/Alt+K (draft swap) and Cmd/Ctrl+Opt/Alt+L (lock) are adjacent, and Opt is Alt, so mis-presses are possible — if you hit the wrong one often, prefer the corresponding icon button.

Requirements

• DeepSeek Harness 0.1.0-rc.6 or newer;
• the web profile;
• a modern Chromium-based browser (Chrome or Edge).

Installation

Install from this GitHub repository

dsh plugin --profile web add github:qiqiangvae/dsh-input-enhancer

Or use the explicit Git URL:

dsh plugin --profile web add https://github.com/qiqiangvae/dsh-input-enhancer.git

For reproducible installs, pin a commit:

dsh plugin --profile web add 'github:qiqiangvae/dsh-input-enhancer#<commit-sha>'

Install from a local directory

git clone https://github.com/qiqiangvae/dsh-input-enhancer.git
dsh plugin --profile web add ./dsh-input-enhancer

Verify

dsh --profile web --dump-config | grep dsh-input-enhancer

Then restart dsh web and refresh the page.

Usage

1. Start DeepSeek Harness Web:

``sh dsh web ``

2. Find the lock button in the composer tool row, near the model selector and the send button.

3. Toggle the lock:

- Click the lock button in the composer tool row; - or press Ctrl+Alt+L (Windows/Linux) / Cmd+Alt+L (macOS), which only acts while the composer is focused.

4. While locked:

- The composer enlarges for long-form editing. - Plain Enter does not send. - Ctrl+Enter / Cmd+Enter does not send. - Shift+Enter still inserts a newline. - IME composition Enter still confirms the candidate. - Clicking the official send button still sends; the lock only guards keyboard input. - Press Enter 3 times (within 800ms each) to unlock and send immediately (the lock icon shows "1"/"2" on the first two taps, then plays an unlock burst on the third).

5. Lock state is per session and is kept in memory only. It is cleared on refresh or restart.

6. The character count is independent of the lock: whenever the composer is non-empty (locked or not), a character-count badge appears right after the lock button.

7. Park a half-finished draft:

- Click the swap button (⇄) left of the lock button, or press Cmd+Opt+K (macOS) / Ctrl+Alt+K (Windows/Linux); - When the slot is empty, the composer's draft moves into the slot and the composer empties; - When the slot is full, the two swap (the staged draft returns to the composer, the current input moves into the slot); - The slot is in-memory only and is cleared on refresh.

Configuration

The plugin is zero-configuration. It requires no API key, no settings fields, and no settings.yaml entry. Lock state and the staging slot live in browser memory only.

Limitations

• Lock state is browser-memory only; it does not write settings.yaml and makes no network requests.
• The staging slot is likewise browser-memory only (one slot per conversation); it is cleared on refresh/restart, never crosses sessions, and is never written to disk or sent over the network.
• The plugin uses the official conversation.input.right slot and does not replace the composer.
• Enlargement is implemented via CSS variables (min-height and --dsh-composer-text-max-height); the official bottom anchor --dsh-composer-height re-syncs automatically as the height changes.

Troubleshooting

The lock button is not visible

1. Verify that the plugin is mounted:

```sh

dsh --profile web --dump-config | grep dsh-input-enhancer

```

2. Restart dsh web and force-refresh the page (Ctrl+F5). 3. Make sure you are using the web profile.

The shortcut is unavailable

1. Make sure the composer is focused (the shortcut only acts while it is). 2. Use Ctrl+Alt+L (Windows/Linux) or Cmd+Alt+L (macOS), not Ctrl/Cmd+L (reserved for the address bar). 3. Some Linux desktop environments bind Ctrl+Alt+L to a system action (lock screen / layout switch), which will intercept it; use the lock button instead.

A message was sent while locked

• Shift+Enter inserts a newline; it is not a send.
• Clicking the official send button is a deliberate mouse action and is not blocked.
• Check that the lock button shows the red filled locked state and review which Enter combination was pressed.

The composer did not enlarge while locked

• Make sure the lock button shows the red filled locked state.
• If another plugin or theme overrides --dsh-composer-text-max-height or [data-composer-card] min-height, this plugin's enlargement may be overridden; check for style conflicts.

Uninstall

dsh plugin --profile web remove dsh-input-enhancer

Migration from dsh-enter-lock

This plugin was renamed and enhanced from dsh-enter-lock. If you previously installed the old name, uninstall it first, then install this plugin:

dsh plugin --profile web remove dsh-enter-lock
dsh plugin --profile web add github:qiqiangvae/dsh-input-enhancer

Compared with dsh-enter-lock, this plugin adds:

• Enlarge composer: locking grows the composer for long-form editing;
• Triple-Enter send: press Enter 3 times to unlock and send immediately (with count flashes and an unlock-burst animation);
• Character count: a live character count, independent of the lock;
• Long-text warning: past 800 characters the badge turns amber;
• Draft swap: a ⇄ swap button + Cmd/Ctrl+Opt/Alt+K to exchange half-finished drafts between the composer and a staging slot (one slot per conversation, in-memory).
