+### `retry_condition`
+
+Use any valid expression to decide the continuation of retries. If expression resolves to `false`, then the action interrupts retries. Default value is `true`.
+```yaml
+- uses: Wandalen/wretry.action@master
+  with:
+    action: owner/action-repo@version

+**Attention**. The expression can be wrapped by expression tokens `${{ <expr> }}`. Github workflow runner resolves expressions wrapped in the tokens to a specific value and replaces action input. The expression without tokens will be resolved by the action for each retry. If you don't need recalculations put the expression in the expression tokens.
