To document undocumented legacy code, you can reverse-engineer formal technical specifications from observed runtime behavior. This process analyzes specific code clusters to generate spec deltas and inline annotations, mapping legacy systems to architectural requirements.

Reverse-engineering a specification from existing code involves drafting formal requirements based on actual code execution rather than aspirational design. It operates on code clusters identified in coverage reports to produce structured spec deltas and task lists.

You create reviewable PRs for retroactive code documentation by generating ghost change management artifacts that include spec deltas, task lists, and inline code annotations. This structured workflow ensures legacy system updates align with organizational standards.

Yes, you can generate spec deltas from a coverage report for a legacy service by running reverse-spec analysis on specific code clusters. The process produces formal requirements and code annotations that satisfy architectural compliance and testability standards.

Reverse-spec analysis requires a cluster name provided in your coverage report to target the undocumented codebase. You run the process for the specified application using that cluster identifier to map observed behavior to formal requirements.

You should use reverse engineering for technical specifications when a legacy service lacks documentation and technical debt needs reduction. It maps actual observed code behavior to architectural requirements, ensuring undocumented system functionality is properly specified for compliance.
