Microsoft-Decision-1 (Azure AI Foundry System One) decision provider for bounded agent decisions. Registers typed-decision tools (decision_noul, decision_choice, decision_score, decide) that preserve full probability distributions, plus an opt-in pre_tool_call hook that requests human approval for known-risk calls without sending their arguments to Azure. Reference implementation of the typed decision-provider runtime in #113008.

## Good to know before installing

The four decision tools send the caller-supplied state/questions text to the Azure Foundry endpoint you set in AZURE_FOUNDRY_BASE_URL (nothing is sent while it is unset); with MS_DECISION_GATE=1 the pre_tool_call gate sends only a coarse operation label for known-risk tool calls to that endpoint and routes them to Hermes's human approval prompt (MS_DECISION_GATE_MODE=block hard-denies instead); the labelled eval corpus under tests/ contains literal destructive commands as should-refuse examples.

From the plugin's catalog listing.

## How to install

1. Install it. Hermes asks for any API keys it needs (this one needs `AZURE_FOUNDRY_API_KEY`, `AZURE_FOUNDRY_BASE_URL`), then asks whether to turn it on.

```bash
hermes plugins install ms-decision-provider
```

2. Said no? Turn it on later:

```bash
hermes plugins enable ms-decision-provider
```

3. Restart Hermes so it loads the plugin.

Some plugins also need a sign-in or settings: see the official page. Memory plugins ask whether to become your memory provider instead. Steps follow the official plugins guide: https://hermes-agent.nousresearch.com/docs/user-guide/features/plugins
