dsh-codex-select
Codex-style code selection for the DeepSeek Harness Web GUI.
Select code in a workspace file viewer — it is automatically added to the
message as a reference chip (no button, no code dumped into the draft text),
and at send time the selection is serialized into the prompt as context,
exactly like Codex.
Features
- 文件 / Files conversation view tab: lazy workspace file tree (skips
node_modules / .git by default, toggles included) + read-only file
viewer (UTF-8 text only, ≤ 1 MiB, binary rejected).
- Codex-style selection: select code inside the viewer — a chip appears
above the composer:
已选中 N 行 · <file>, and a matching reference
chip is inserted into the composer automatically.
- No button, no draft pollution: the code never lands in the visible draft
text; the input machine serializes the chip through the plugin codec into a
fenced code block with a file-path comment when you send.
- × clears the chip; selecting different code replaces the previous chip;
collapsing the selection keeps the chip (Codex behaviour).
Install
dsh plugin --profile web add dsh-codex-select
dsh web
Restart dsh web after install, then open a session and click the
文件 / Files tab.
Usage
- Click the 文件 / Files tab next to the conversation tabs.
- Expand the workspace file tree (left) and click a file to view it (right).
- Select code in the viewer — a chip
已选中 N 行 · 文件名 appears above
the composer, and the selection is attached to the message automatically.
- Type your prompt and send — the selected code rides the message as context.
- × on the chip removes the selection.
How it works
cordis.patch.yml — bundle patch inserting the codex-select host row.lib/index.js — host half: GET /dsh-codex-select/list|read (same-origin
routes, same trust model as the core directory picker).lib/client.js — browser half:
- a
conversation.view entry (the Files tab),
- a
conversation.input.dock entry (the chip bar above the composer),
- an input-trigger source named
codex-select whose codec serializes
the reference chip at submit time (async fetch-by-path fallback so chips
survive reloads).
Security
The host routes share the harness web server's trust model: anyone who can
reach the harness can list/read absolute paths on the host account — the same
capability the core directory picker already exposes. The viewer is
read-only; this plugin never writes or executes files.
