TapPass governance for DeepSeek Harness

The authority layer for agentic AI, as a DeepSeek Harness plugin.

Everything in DeepSeek Harness is a plugin. This is the one that decides what your agents are allowed to do.

Guardrails and safety classifiers ask "is this output harmful?" That is a property of the model. TapPass asks a different question: "is this agent allowed to do this, under our rules, right now?" That is a property of your business, and no model level tool can answer it, because the answer lives in your organisation, not in the weights.

This plugin intercepts every tool call at the harness's tools/pre-execute seam, sends it to the TapPass policy decision point (POST /v1/govern), and allows, denies, or escalates it for human approval.

Why it is different

• Business rules, not model safety. Write the rule once, in your language: "refunds over 500 need a human", "no customer PII leaves the EU region", "this agent may read the CRM, never write it". It is enforced on every tool call, on every harness, under every model. A prompt is a suggestion. A policy is a fact.
• Authority is earned. The plugin ships in observe mode: from the first minute it watches and records every call, and blocks nothing. You see what your agents do before you enforce a single deny. Then you turn on enforcement for what matters. Autonomy is a track record, not a checkbox.
• Harness and model agnostic. The same rules that govern an agent here govern it in Claude Code, in Codex, behind LiteLLM. The harness is interchangeable. The authority is not.
• EU hosted, EU AI Act ready.

Install

# create a profile if you do not have one, then add the plugin
dsh plugin --profile default add @tappass/dsh-governance

# point it at your TapPass workspace
export TAPPASS_API_KEY="tp_dev_..."      # a TapPass developer key

# verify the layer without booting, then run
dsh --profile default --dump-config
dsh --profile default

Get a developer key from your TapPass dashboard (Settings, Developer keys) or POST /api/agents/{agent}/developer-keys. The key is bound to one agent and one org; TapPass records the audit trail against it.

Configure

Every tool call is governed once it is installed. Configuration is optional; the defaults are safe.
