+"""OpenFang — vendored binary sidecar for agent tool execution.
+
+OpenFang is a Rust-compiled Agent OS that provides real tool execution
+(browser automation, OSINT, forecasting, social management) in a
+WASM-sandboxed runtime.  Timmy's coordinator dispatches to it as a
+tool vendor rather than a co-orchestrator.
+
+Usage:
+    from infrastructure.openfang import openfang_client
+
+    # Check if OpenFang is available
+    if openfang_client.healthy:
+        result = await openfang_client.execute_hand("browser", params)
