What problem does it solve? Reimplementing a software system from specification documents is error-prone and token-expensive when done ad hoc. This Skill turns the specification artifacts produced by the Reversa framework into an executable, resumable reconstruction plan and implements each task on demand, reading only the files each task needs. ## Core Features & Use Cases - Plan Generation: Reads a minimal set of spec files (architecture, dependencies, gaps, confidence report) and produces _reversa_sdd/reconstruction-plan.md with tasks ordered bottom-up: database schema, domain entities, state machines, leaf units, API layer, and user flows. - Migration-Aware Reconstruction: Detects completed migrations via _reversa_sdd/migration/handoff.md and lets the user choose between rebuilding from original specs or from target-stack migration specs, including cutover and parity-validation tasks. - Token-Preserving Execution: Executes one task at a time, reading only the files listed in each task's Lê: field, marking status in the plan, and pausing for user decisions on spec gaps. - Use Case: After running Reversa on a legacy codebase, copy _reversa_sdd/ into a fresh directory and invoke the Skill to reimplement the system task by task, pausing and resuming at any point. ## Quick Start Ask the agent to run /reversa-reconstructor in a directory containing the _reversa_sdd folder to generate the reconstruction plan and start executing tasks.
