Anyone tried Thoughtworks' new AI/works legacy modernization platform

Thoughtworks recently launched a new agentic development platform called AI/works™. The marketing claims are quite bold, specifically targeting the "legacy modernization" problem space (which we all know is usually a nightmare).

According to the announcement and their technical guide, the workflow is:

Ingestion: "Blackbox" reverse-engineering of legacy binaries/code (even without full source access in some cases).

Specification: It generates a "SuperSpec" — a machine-readable functional specification enriched with regulatory/security context.

Forward Engineering: Agents use the Spec to generate new code, tests, and pipelines.

Lifecycle: It claims to support a "3-3-3 delivery model" (Idea to Production in 90 days) and includes self-healing/regenerative capabilities for maintenance.

This sounds like the "Holy Grail" of software engineering, but I am skeptical about how well this works on actual enterprise spaghetti code versus carefully curated demos. "Reverse engineering into a perfect spec" is historically where these tools fail.

I’m looking for insights from anyone who has piloted this or works at TW:

How does the "Code-to-Spec" reverse engineering actually handle heavy technical debt or undocumented business logic?

Is the "SuperSpec" truly editable/maintainable by humans, or does it become a new black box?

How much "human in the loop" is actually required for the 3-3-3 model?

Is this built on public LLMs (Claude/GPT-4) or proprietary models trained on legacy patterns (like COBOL/Mainframe data via their Mechanical Orchard partnership)?

Any details on the reality behind the marketing would be appreciated.
