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 — both files and snippets:
  • 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;
  • add a whole file to the context by clicking the ＋ button on a file tree row (or the toolbar's 加入文件 / Add file button) — the entire file is attached as context.
• No button, no draft pollution: the content 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; a new pick (code or file) replaces the previous chip; collapsing a code 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

1. Click the 文件 / Files tab next to the conversation tabs.
2. Expand the workspace file tree (left) and click a file to view it (right).
3. 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.
4. Type your prompt and send — the selected code rides the message as context.
5. × 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.
