Claude Opus and Codex introduce dynamic workflows for verifiable tasks
Surveyor extracts a behavioural specification from your undocumented legacy code. Assay runs that same specification against both the legacy system and its rewrite — so nothing breaks in translation.
Scans a legacy codebase, drives an LLM through architectural discovery, and emits a behavioural specification, schemas, and binding skeletons. Read-only on the source. Every artefact ships as a draft for human review before it becomes canonical.
Runs the behavioural specification against any target. Same scenarios, two systems, two passing test runs. Specs are the contract; only the binding changes between the legacy and the rewrite.
Undocumented, untested, years old.
An architectural model, tech-choice MADRs, and behavioural scenarios.
A runnable behavioural contract you can review, edit, and version.
Same specs, two systems — both green.
Stop guessing what your legacy system actually does. Get Surveyor and Assay before public release — we onboard you on your first legacy system and learn from your feedback.
Want to talk first? Book a 30-minute call with our engineering team. We'll look at your system together and tell you honestly what we'd do — Surveyor or no Surveyor.
