Why this exists

DeepSeek Harness ships its own web_search / web_fetch backends, which means another API key and another bill. But plenty of people already pay for a Z.AI plan — and that quota can already run web_search_prime and webReader server-side. Nobody had wired it up.

This plugin does exactly that. One email login turns your existing subscription into the harness's search and fetch capability. Installing it is enough; the tool names and arguments the model sees do not change, only the service behind them.

Features

Capability	What it does
Web search	Replaces the official `web_search` backend with `web_search_prime`
Web reader	Replaces the official `web_fetch` backend with `webReader`
Vision	Adds a `zai_vision` tool for image description, OCR and visual Q&A
Zero dependencies	No `node_modules`, no `dependencies`, no `peerDependencies`
Status line	`/dsh-glm-status` shows token age, plan expiry and remaining quota

Install

From the Plugin Manager

Open Plugins → Add plugin, type the package name, and press Install:

dsh-glm-web-search

Leave the install source on npm — or switch it to Mainland China mirror (npmmirror) if the official registry is slow; both serve the same tarball. Restart the harness afterwards: plugin code is loaded at startup, so a freshly installed plugin is not active until then.

From the command line

dsh plugin --profile desktop add dsh-glm-web-search

From this repository

For a local checkout, or to pin an exact commit:

dsh plugin --profile desktop add github:czpGhost/dsh-glm-web-search
dsh plugin --profile desktop add /absolute/path/to/dsh-glm-web-search

Nothing here runs a build script, so pnpm never asks you to allowlist one.

/dsh-glm-web-search login

Your browser opens the authorization page; the token is stored automatically on approval. From then on web_search and web_fetch resolve to Z.AI.

Usage

/dsh-glm-web-search login     # sign in (opens your browser)
/dsh-glm-web-search logout    # sign out, forget the local credential
/dsh-glm-web-search status    # token, plan and quota

/dsh-glm-login     /dsh-glm-logout     /dsh-glm-status    # equivalent aliases

Each subcommand is also a standalone command because the menu matches on a command's name: typing /dsh-glm-log is what surfaces both login and logout.

Upgrading

The Plugin Manager does not auto-update installed plugins. Remove the old version first, then add the new one:

dsh plugin --profile desktop remove dsh-glm-web-search
dsh plugin --profile desktop add dsh-glm-web-search

Then restart. Your credential lives outside the package, so it survives an upgrade.

Screenshot

/dsh-glm-status:

  ▸ token 30m · Start Plan · GLM-5.3 2.95M left · resets 2h 57m

      account  you@example.com
               token valid 30m

      plan     ZCode Start Plan [active] · ends 10-12 23:59 (3d 2h)
      quota    GLM-5.3        ██████████  98%  2.95M/3M   resets 2h 57m
      quota    GLM-5.3-Flash  ██████████ full      resets 2h 57m
      cycle    daily grant, refills at 00:00 Asia/Shanghai

The quota bar draws remaining, not used. Drawn as used, a brand-new account would render as an empty bar — which reads as "exhausted", exactly backwards.

Configuration

Field	Default	Purpose
`origin`	`https://zcode.z.ai`	Gateway origin
`model`	unset (resolved live)	Model that runs search and fetch
`appVersion`	probed	Client version advertised to the gateway
`jwtEnv`	`ZAI_JWT`	Credential reference
`tokenPath`	`$DSH_HOME/dsh-glm-web-search/token.json`	Local token file
`vision`	`true`	Register the `zai_vision` tool
`timeoutMs`	`90000`	Per-request deadline

Credential order: managed record → $ZAI_JWT → the local token file. On a headless host, set ZAI_BROWSER_OPEN=0; the URL is still printed so you can open it yourself.

Two things worth knowing

Search results are capped. Upstream returns at most 10 sources per web_search call, and the harness's dsh-tool-web then truncates sources[] to 8 (setting truncated: true). One call may carry up to 4 queries, run concurrently; the merged result still hits the 8-source cap.

It has no dependency tree at all. src/ reaches the harness only through injected services (ctx.web, ctx.tools, ctx.commands), and imports nothing outside its own tree except Node builtins — so there is no node_modules, no dependencies, and no peerDependencies. That matters beyond tidiness: declaring a @deepseek-ai/dsh-* peer makes the harness's install preflight compare your range against the runtime version and reject the whole installation when they disagree.

The subtler hazard is a second copy of a stateful harness package. Same version, byte-identical files, and it still breaks: two files mean two module instances, and a module-local Symbol() differs between them. @deepseek-ai/dsh-tools keys its internal scheduler on exactly that (const TOOL_RUNTIME_SCHEDULER = Symbol("@deepseek-ai/dsh-tools.scheduler")), so @deepseek-ai/dsh-agent-loop reaching through ctx.tools[TOOL_RUNTIME_SCHEDULER] finds undefined and the turn dies with Cannot read properties of undefined (reading 'prepare'). Symbol.for() keys live in a global registry and survive duplication — schemastery uses one, which is why it is safe to appear twice and dsh-tools is not.

Roadmap

FAQ

Do I need a paid Z.AI plan? No. A free account gets an experience plan that already covers search and fetch. Vision needs the Flash model, which the same plan includes.

Where is my credential stored? $DSH_HOME/dsh-glm-web-search/token.json — one file, no environment variables required. Delete it or run logout to revoke locally.

Why do I only get 8 results? That is the harness's own cap, not Z.AI's. Upstream returns 10; dsh-tool-web trims to searchMaxResults (default 8). Raise it in that plugin's config if you need more.

Does this work headless? Yes. Set ZAI_BROWSER_OPEN=0 and login prints the URL instead of opening a browser.

Will it break when Z.AI ships a new client? Possibly — the gateway fingerprints the client, so a new ZCode build can invalidate the identity constants. That is a one-line fix here, not a redesign.
