[[command]]
name = "rbs"
description = "Ruby's standard-library tool for working with RBS type signatures. Read-only subcommands: `ast` (print env JSON), `list`, `ancestors`, `methods`, `method`, `constant`, `paths`, `parse` (syntax check, including from -e CODE strings), `validate`, `subtract`, `diff`. `annotate` rewrites RBS files in place to pull RDoc comments. `prototype rb` and `prototype rbi` generate RBS by parsing source — when -o or --out-dir is given they write files. `prototype runtime` introspects loaded classes at runtime (loads application Ruby — same risk profile as `rails runner`). `vendor` copies gem RBS into vendor/sigs (project-local SafeWrite). `collection install/update` write rbs_collection.lock.yaml and download/copy gem RBS. `test` is a runtime wrapper that spawns the target program with type-check shims — not pure analysis. Stable bundled with Ruby; v4.x line is current."
