+title: enable wasm builder diagnostics propagation
+
+doc:
+  - audience: Runtime Dev
+    description: |
+      `substrate-wasm-builder` is used as a build dependency by crates that implement FRAME runtimes.
+      Errors that occur in these crates can not be detected by IDEs that use rust-analyzer as a language
+      server because rust-analyzer needs the errors to be reported as diagnostic message in json format to
+      be able to publish them to language server clients. This PR adds `WASM_BUILD_CARGO_ARGS` environment
+      variable, which can hold a space separated list of args that will be parsed and passed to the `cargo`
+      command that it is used for building against wasm target. It can be used for the stated initial case,
+      but it is also flexible enough to allow passing other arguments or formatting the messages using another
+      available type.
