+# @uncaged/workflow-agent-hermes
+
+`AgentFn` adapter that runs the `hermes` CLI in non-interactive `chat` mode (Nerve-style flags: `-q`, `--yolo`, `--quiet`, bounded `--max-turns`).
+
+The agent composes the same thread-aware prompt as other CLI-backed agents via `buildAgentPrompt` from `@uncaged/workflow-util-agent`, then spawns `hermes` and returns stdout on success.
+
+## Install
+
+```bash
+bun add @uncaged/workflow-agent-hermes @uncaged/workflow @uncaged/workflow-util-agent
+```
+
+In this monorepo: use `workspace:*` for all three `@uncaged/*` packages.
+
+## Usage
+
+```typescript
+import { createHermesAgent } from "@uncaged/workflow-agent-hermes";
+
+const agent = createHermesAgent({
+  model: "your-model", // or null to omit --model
+  timeout: 600_000, // ms, or null for no timeout
+});
+```
+
