+# Remove redundant uses of flow (fp-ts/no-redundant-flow)
+
+Suggest removing `flow` when it only has one argument. This can happen after a
+refactoring that removed some combinators from a flow expression.
+
+**Fixable**: This rule is automatically fixable using the `--fix` flag on the
+command line.
+
+## Rule Details
+
+Example of **incorrect** code for this rule:
+
+```ts
+import { flow } from "fp-ts/pipeable";
+import { some, Option } from "fp-ts/Option";
+
+const f: (n: number): Option<number> = flow(some);
+```
+
+Example of **correct** code for this rule:
+
+```ts
+import { flow } from "fp-ts/pipeable";
+import { some, filter, Option } from "fp-ts/Option";
+
+const f: (n: number): Option<number> =
+  flow(
+    some,
+    filter((n) => n > 2)
+  );
+```
