rc-minitest-openapi turns Rails minitest integration tests into the source of truth for an OpenAPI 3.0 document. Tests declare each operation and its response schema, the live response is validated against that schema as the suite runs, and the openapi:generate rake task writes the document. An rswag-style block DSL and plain helper methods are both supported.

An unofficial community extension for RubyLLM. It adds policy-bound, read-only browser Inspect and Extract tools with an offline FakeBackend. The Stagehand Ruby SDK adapter is present but unsupported for live operations until provider egress and cleanup are qualified.

The full live Act protocol is deferred to a later version. The Gem core works in plain Ruby without Rails.
