reverse-engineering-skill

Identifies missing, vague, underspecified, or contradictory business logic within BL documents. Finds incomplete edge cases, missing state transitions, ambiguous terminology, and weak billing rules. Use when reviewing business logic quality, hardening requirements, or preparing BL for implementation.

Converts trusted business logic into product-owner-grade acceptance criteria and developer-ready tasks using Given/When/Then scenarios. Use when creating user stories, preparing for sprints, or turning BL into executable requirements.

Generates scenario tests, rule tests, edge case tests, state transition tests, and billing tests from trusted business logic. Use when creating test suites from BL, ensuring BL coverage, or turning requirements into verifiable tests.

Rewrites vague business logic into deterministic, testable rules by separating policy from mechanism, normalizing terminology, and defining explicit state machines. Use when preparing BL for code implementation, making BL executable, or normalizing ambiguous requirements.

Reverse engineers business logic from source code by extracting operational business truth. Use when user asks to understand what the system actually does, analyze business rules, extract domain logic, infer workflows from code, explain state transitions, or identify decision logic. Works with API views (Django, FastAPI, etc.), domain models, background tasks, and multi-step workflows.

Tailors the universal BDD skills in this directory to a specific project. Use when adopting BDD skills in a new repo, defining where BL docs live, which terminology to use, and how to find entry points (views, models, tasks). Creates or updates project BDD config so other skills (reverse-engineering, validate, derive-acceptance-criteria, etc.) work correctly.

Verifies whether documented business logic is actually implemented by mapping BL rules to code evidence. Flags rules as implemented, partially implemented, contradicted, or not found. Use when validating business logic documents, checking code coverage against requirements, or verifying BL-to-code alignment.
