This evidence comes from the upstream catalog. This site has not installed, run, or security-reviewed the plugin.

Install

Start with a prompt that asks an agent to review the GitHub repository and source. Switch to the command if you want to install it yourself.

Copy this prompt into DSH, Codex, or another agent and ask it to review the GitHub repository and source first.

Do not install or run any commands yet. Read this plugin's GitHub repository, README, and relevant source code. Then answer the questions below clearly and directly so I can decide whether it fits my needs:

1. What is this plugin, and what problem does it solve?
2. Who is it for, and what are its typical use cases?
3. How is it used after installation? Include one minimal example.
4. What known limitations or privacy, security, compatibility, or maintenance risks does it have?
5. Give a clear recommendation: recommend, conditionally recommend, or do not recommend, with reasons.

Distinguish statements documented by the repository, inferences from source code, and unknowns. If evidence is insufficient, say so explicitly. Do not guess or simply repeat the README.

@agentvalet/dsh

Governed platform access for DeepSeek Harness agents: an agent calls Slack, GitHub, Gmail, Stripe, or any other AgentValet-connected SaaS platform through a broker that enforces the owner's grants and approval flow, with no API key stored on the machine the agent runs on.

Install

dsh plugin --profile web add @agentvalet/dsh

This installs both plugins the bundle ships: av-identity (the agentvalet service) and av-tools (the four tools below). Restart or reload the profile after installing.

Connect

An installed but unconnected profile has no identity yet — calls report "not connected" rather than failing obscurely. To connect it:

1. In the AgentValet dashboard, generate a single-use bootstrap token for a new agent. 2. Run the bundle's connect command:

AGENTVALET_BOOTSTRAP_TOKEN=<token> npx agentvalet-dsh-connect --profile web

--token <token> works too; the environment variable just keeps the token out of your shell history. The command prints the new agent id and nothing else — never the token, never the key. --help lists the rest of the flags.

Connecting is a command you run, not a tool the agent can call. An enrolment tool would let an agent bootstrap its own identity with no human in the loop, and the identity would stop attesting to a person's decision to create it.

The command generates an RS256 keypair locally and sends only the public key to AgentValet's /v1/agents/bind endpoint. The private key never leaves the machine. It is written to $DSH_HOME/agentvalet/<profile>.json (~/.dsh/agentvalet/... when DSH_HOME is unset) at mode 0600, and the store refuses outright to write anywhere inside a git working tree.

Once bound, the agent shows up in the dashboard deny-by-default — it can call nothing until the owner grants it specific platforms and scopes.

A bootstrap token is single-use. Re-running connect on an already-connected profile is refused rather than silently replacing the identity, so one agent's audit history can never be laundered into another's.

The routing instructions it writes

Connecting also writes a short routing block into $DSH_HOME/AGENTS.md — the rule that platform calls go through AgentValet rather than around it. The block sits between <!-- agentvalet:start --> and <!-- agentvalet:end --> fences: anything else in that file is yours and is left untouched, and re-running connect refreshes the region in place instead of appending a second copy.

It is written there because that is where dsh reads. The instruction loader (@deepseek-ai/dsh-agent-instructions) reads $DSH_HOME/AGENTS.md and then each directory from the project root down to the session cwd — it never scans node_modules, so the AGENTS.md shipped inside this package reaches no model. That copy is documentation for you to read or paste into a project root.

Note it follows $DSH_HOME, not --home: --home only relocates where the identity is stored, and following it would put the file somewhere nothing reads. If the write fails, connect says so and still reports the enrolment — by then the single-use token is spent and the agent exists, so failing the whole command over a markdown file would strand a real identity.

The block deliberately contains no agent id, owner id, or scope list. This file lands in a home directory and gets copied into project roots and pasted into issues; identity in it would leak through ordinary use.

Tools

ToolMethodNotes
agentvalet_list_platformsLists platforms and scopes the owner has approved for this agent. Call this before any platform call — grants can change at any time.
agentvalet_read_platformAlways GETRead from an approved platform.
agentvalet_write_platformPOST (default), PUT or PATCHCreate or update. May require owner approval.
agentvalet_delete_platformAlways DELETEUsually requires owner approval.

Every tool takes the platform id and scope string exactly as returned by agentvalet_list_platforms, plus an endpoint. All four resolve to { ok: true, data } on success or { ok: false, error } on failure — a denial, a pending approval, or a suspended agent all come back as a plain result the model can read and explain rather than as a thrown error. (That is a guarantee about our own tool bodies. Argument validation happens in the harness before our code runs, so a malformed call comes back in dsh's own isError result shape instead.)

What this does NOT do

  • No local policy engine. Every grant, scope, and approval decision is

evaluated by AgentValet's proxy, not by anything running on this machine.

  • No vault on disk beyond the agent's own signing key. There is no

platform credential to steal locally — API keys for Slack, GitHub, and the rest live only at the broker, never on the agent's host.

  • No sandboxing. This plugin governs which platform calls succeed; it

is not a substitute for running the harness in a sandbox and pairs with one rather than replacing it.

  • No sub-agent delegation and no attenuated scope re-issue. This bundle

implements neither. It enforces the owner's grants for this one agent, and that is all it does.

Compatibility

Declared harness range: >=0.1.0-rc.5 <0.2.0. Verified against @deepseek-ai/dsh@0.1.0-rc.7, @deepseek-ai/cordis@4.0.1, and @deepseek-ai/dsh-tools@0.1.0-rc.7 — see VERIFICATION.md for what was and was not confirmed against a real harness run.
