SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill validates L88_IMPLEMENTATION_PAYLOAD contracts and ensures reliable handoff from B4 (producer) to B4C (consumer), enabling deterministic preload workflows.

Core Features & Use Cases

  • Payload validation for B4 → B4C handoffs.
  • End-to-end verification of producer/consumer preload pipelines.
  • Clear acceptance criteria mapping to L88_ENGINEERING and test result reporting.

Quick Start

Use this skill to validate L88_IMPLEMENTATION_PAYLOAD by preparing a minimal contract payload and triggering the preload workflow between B4 and B4C to confirm proper handoff.

FAQPage Schema
How do I validate a payload contract for producer and consumer handoffs?

Payload contract validation for producer and consumer handoffs is performed by checking file presence, mapping acceptance criteria from engineering specs, and verifying test results. This ensures a deterministic preload workflow between modular components.

What is an L88 implementation payload and when do I need to validate it?

An L88 implementation payload is a contract structure used for engineering handoffs from producer to consumer. You need to validate it when coordinating preload workflows across modular components to ensure correct file presence and test coverage.

How do I handle blocked files during a B4 to B4C contract handoff?

Blocked files during a B4 to B4C contract handoff require explicit handling to maintain workflow integrity. The validation process enforces checks that identify blocked files and reports them alongside test results before the handoff completes.

Does contract validation work with BDD acceptance criteria from engineering specs?

Contract validation works with BDD acceptance criteria by mapping coverage directly from L88 engineering specifications. It verifies that payload handoffs meet these criteria through enforced test result reporting and file presence checks.

What is the best way to verify producer and consumer preload pipelines end to end?

The best way to verify producer and consumer preload pipelines is by validating the implementation payload contract, which enforces file presence checks, acceptance criteria coverage, and explicit handling of blocked files across modular components.

Why does my B4 to B4C payload handoff fail validation?

B4 to B4C payload handoff validation fails when required files are missing, acceptance criteria from L88 engineering are not covered, or blocked files are not explicitly handled. The validation enforces strict file presence checks and test result reporting.
