Introduction
dsh-at-file
Workspace path references for the DeepSeek Harness web interface. Type @ in the composer to search the current workspace and insert a file or directory path.

Usage
Choose a result from the @ menu. The selected path remains visible in the draft and can be opened or removed from the reference bar.
Review @docs/spec.pdf
Before the agent starts a step, the plugin confirms that the path exists inside the active workspace. It then adds a short reference message:
<workspace-reference path="docs/spec.pdf" kind="file" />
The reference contains the workspace-relative path and its kind. The plugin does not open the referenced file or list the contents of a referenced directory. The agent can inspect the path with the tools available in the current session when the task requires it.
File format and file size do not change this behavior. A PDF follows the same path-reference flow as any other workspace file.
This mechanism applies to version 0.3.0 and later. Earlier releases read file content during submission and enforced file-size limits.
Path Picker
Plain queries match filenames. Exact names, prefixes, and compact matches rank ahead of looser results, without matching letters scattered across a long directory path.
A query containing / matches path segments in order. For example, src/view can find src/client/view.ts. A trailing slash such as src/ searches within that path.
When a directory is highlighted, press ArrowRight to enter it. The draft advances to @path/ without a trailing space, and the candidate menu stays open for the next selection. Enter and pointer selection keep the existing behavior and finish the directory reference.
Each result shows the filename first and its parent directory underneath. Duplicate filenames include the parent directory in the main label. Built-in SVG icons distinguish folders, source files, text, PDFs, images, data and configuration files, archives, and other files.
The default index skips common version-control directories, IDE metadata, dependency trees, caches, and build output. The list covers VS Code, Visual Studio, JetBrains IDEs, Fleet, Eclipse, Android and Gradle, Xcode, CMake, Flutter, .NET, Unity, Unreal, and common JavaScript and Python output directories.
Install or Update
dsh plugin --profile web add https://github.com/omdsh-dev/dsh-at-file/archive/refs/tags/v0.4.0.tar.gz
Use the same command to update an existing installation. Restart dsh web after installation so the Host and browser client load version 0.4.0.
The plugin can be enabled or disabled under Settings -> File mentions.
Configuration
The available options apply to the path picker index:
maxIndexedFilessets the maximum number of indexed workspace entries.ignoreDirsreplaces the built-in list of directory names excluded from the picker. Set it to[]to index every directory.
Add the complete configuration to the selected profile's cordis.patch.yml. The usual path is ~/.dsh/profiles/web/cordis.patch.yml.
- id: dsh-at-file
config:
maxIndexedFiles: 10000
Omitting ignoreDirs keeps the built-in list. When you provide it, include every directory name you want excluded.
Path Handling
- The picker indexes regular files and directories in the active workspace. Configured directory names and symbolic links are skipped.
- The Host accepts workspace-relative paths. Absolute paths and paths that escape the workspace are ignored.
- Reference markers are created only from user-authored text.
- Clicking a referenced path uses the Harness
host.openPathendpoint. - The picker index is cached per session for 30 seconds.
- An
@pathtoken cannot contain whitespace or another@character. maxIndexedFileslimits picker results. A manually entered path can still be referenced when it exists inside the workspace.
The active agent may lack a tool for a particular file format. DSH provides read for UTF-8 text and read_image for supported images. PDF support depends on the tools available in the session.
Development
pnpm install
pnpm run check
pnpm run test
pnpm run build
The development setup expects the Harness checkout at ../dsh. Built files under lib/ are committed so profile installation does not require package build scripts.
