swiftmcp

Format and create a Stage X.Y commit for swiftmcp using the established message format (HEREDOC subject + bullet body + test-count line) and push to origin/main. Wraps git add + commit + push in one user-driven step. User-only invocation — commits land on a public GitHub repository.

Capture verbatim swiftc output for a given option set against the locally installed toolchain. Use BEFORE introducing a new tool whose parser/regex/sanity-check depends on swiftc's exact output shape — prevents format guesses that may drift from the real toolchain. Examples — probe `-warn-long-expression-type-checking` warning format, capture `-emit-sil` heading, verify `frontend -interpret` runtime behavior on host SDK.
