SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

The full Reversa forward pipeline costs seven to nine agent invocations and twelve artifacts, which is heavier than a small change itself. This Skill closes that gap by running a short interview, writing a thin spec, executing the code, and leaving impact traces in one uninterrupted pass.

Core Features & Use Cases

  • Single-pass forward cycle: One interview round, a thin requirements/roadmap/actions spec, code execution, and derived impact traces without intermediate handoffs.
  • Scope gate: Refuses deltas touching more than three modules, data migrations, existing public contracts, auth/payment paths, or more than twelve atomic actions, redirecting them to the full pipeline.
  • Traceability artifacts: Generates legacy-impact.md and regression-watch.md from the real diff, plus append-only progress.jsonl, so partial executions can be resumed by /reversa-coding.
  • Use Case: You need to add a new endpoint to a legacy system already extracted by Reversa. Instead of the full pipeline, run the express pass to spec, implement, and trace the change in one step.

Quick Start

Ask the agent to run the reversa-code-express skill to implement a small feature on the already-extracted legacy base, describing what it delivers and where it touches the code.

FAQPage Schema
How do I implement a small feature without running the full spec pipeline?

Use the express pass: it runs one interview round, writes a thin requirements/roadmap/actions spec, executes the code, and generates impact traces in a single uninterrupted step. It requires an existing context anchor in _reversa_sdd/.

When should I use the express pass instead of the full forward pipeline?

Use it for small deltas on an already-known base: new endpoints, commands, screens, or files touching at most three modules and twelve atomic actions. Anything larger, such as data migrations or changes to existing public contracts, is refused and redirected to the full pipeline.

What happens if the express pass scope check rejects my feature?

The skill explains which scope rule failed and instructs you to run /reversa-requirements to open the full pipeline. It writes nothing to disk after refusing and does not offer to do only the small part.

Does the express pass work without a prior legacy extraction?

No. It requires a context anchor: either architecture.md plus domain.md from a legacy extraction, or prd.md plus SDD specs for greenfield projects. Without either, it aborts without writing anything.

What happens if the express execution stops halfway?

Completed actions are marked in actions.md and logged in progress.jsonl, while pending actions stay open. The /reversa-coding skill can resume the remaining actions directly, since the express pass uses canonical phase names and action formats.
