+## Incremental migration with rig/globals
+
+When doing a first-pass port, keep the flat module structure by importing
+`call`, `pipeline`, and `parallel` from `"rig/globals"` instead of
+destructuring them from `workflow({ body })`. The launcher runs every program
+inside a workflow context, so ambient calls are live at module top level:
+
+```ts
+import { agent, phase, log, s } from "rig";
+import { call, pipeline } from "rig/globals";
+
+// Agent role: summarize one file.
+const summarize = agent({
+  model: "small",
+  input: s.object({ file: s.path }),
+  output: s.object({ summary: s.string }),
+  instructions: "Summarize the file.",
+});
+
+phase("Discover");
+log("listing source files");
+const raw = await call.text("List TypeScript source files, one per line.");
+const files = (raw ?? "").split("\n").map((f) => f.trim()).filter(Boolean);
+
+phase("Summarize");
+const summaries = await pipeline(files, (file) => call(summarize, { file }, { label: file }));
+export default summaries;
+```
+
+Move `call` and `pipeline` calls inside `workflow({ body })` once the port is
+stable — it enables unit testing and makes input typing explicit.
+`"rig/globals"` is a stepping stone, not a final form.
