dsh-ops: lower-token file and shell tools for DSH

What does dsh-ops do?

dsh-ops is a low-level tool plugin for DeepSeek Harness whose stated goal is token efficiency. It adds a family of ops tools for file, document and shell work, and hides part of the official tool set so the model uses the leaner versions.

The footprint is kept small: the component bundle inserts a single dsh-ops row into a profile, and that row's configuration decides which tools are always present, which are loaded dynamically, and whether Bash, file tools or the host PowerShell are replaced.

Core features

• Native mode tools: File tools return compact output with line numbers and clearer error feedback, intended to stop the model from looping on the same error.
• PTC mode tools: Tools return structured JSON so the model writes less TypeScript in PTC mode. The PTC SDK directory lists 18 APIs: 15 file and document tools plus batching, result references and a loader.
• Dynamic tool loading: The plugin turns on DSH's reserved tools_addition mechanism and discloses tools progressively. Features such as PDF and Word reading or bulk edits across many files are loaded when needed.
• ops-ptc mode: An extra mode that inherits the PTC tool surface and can add batching hints as context, without blocking or rewriting the program the model wrote.
• Shell handling: Bash and host shell hiding are configured separately. On Windows, ops_bash can replace pwsh, or you can keep the official shell.
• OPS sidebar: With dsh-TUI, an optional read-only sidebar shows ops information without taking focus or making extra tool calls.

How to use dsh-ops

1. Initialise the target DSH app first, and check that the host is DSH 0.2.2-rc.1 or later.
2. Install from the app's plugin marketplace by entering the npm package name dsh-ops, then enable it. Unless you know the official npm registry is reachable, the README suggests choosing a custom address and entering the Huawei Cloud mirror.
3. Alternatively, run the npx installer. A profile must be named explicitly:

npx --yes dsh-ops@latest install --profile desktop
npx --yes dsh-ops@latest install --profile web
npx --yes dsh-ops@latest install --profile tui

The desktop profile has to go through the CLI bundled with the desktop app. Adding --dry-run prints the plan without changing the profile.

4. Reload when the app prompts you, and restart it if already loaded code was replaced.
5. Check the result, or remove the plugin later:

npx --yes dsh-ops@latest status --profile desktop
npx --yes dsh-ops@latest uninstall --profile desktop

6. To get the sidebar, enable the dsh-ops/tui row in dsh-TUI and restart.
