Install

Skills CLI

npx skills add meirm/reverse-engineering-skill

Asks which skills and agents to install. Just one: npx skills add meirm/reverse-engineering-skill --skill analyze-business-logic-gaps — add -g for every project.

Claude Code

git clone https://github.com/meirm/reverse-engineering-skillcp -r "reverse-engineering-skill/skills/analyze-business-logic-gaps" ~/.claude/skills/

Copies the analyze-business-logic-gaps skill into ~/.claude/skills/ for every project (use .claude/skills/ for one project). Repeat for the other skills listed below.

Plugin

/plugin marketplace add meirm/reverse-engineering-skill

Run inside Claude Code if the repository ships a plugin marketplace, then pick plugins from /plugin.

Skills can run code on your machine — read the SKILL.md first.

What it does

In the author's own words, from each skill's SKILL.md.

  • analyze-business-logic-gaps

    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.

    skills/analyze-business-logic-gaps/SKILL.md on GitHub (opens in a new tab)
  • bdd-orchestrator

    Orchestrates the full BDD workflow from code to trustworthy business logic — extraction, validation, gap analysis, refinement, acceptance criteria, and test generation. Use when the user requests comprehensive analysis like "understand [feature] from code", "analyze [domain] end-to-end", or "prepare [feature] for implementation or sprint planning", coordinating the other BDD skills step by step.

    skills/bdd-orchestrator/SKILL.md on GitHub (opens in a new tab)
  • derive-acceptance-criteria-from-business-logic

    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.

    skills/derive-acceptance-criteria-from-business-logic/SKILL.md on GitHub (opens in a new tab)
  • generate-tests-from-business-logic

    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.

    skills/generate-tests-from-business-logic/SKILL.md on GitHub (opens in a new tab)
  • refine-business-logic-for-implementation

    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.

    skills/refine-business-logic-for-implementation/SKILL.md on GitHub (opens in a new tab)
  • reverse-engineering-business-logic

    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.

    skills/reverse-engineering-business-logic/SKILL.md on GitHub (opens in a new tab)
  • tailor-bdd-skills-for-project

    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.

    skills/tailor-bdd-skills-for-project/SKILL.md on GitHub (opens in a new tab)
  • validate-business-logic-against-code

    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.

    skills/validate-business-logic-against-code/SKILL.md on GitHub (opens in a new tab)

Review before you install

A skill is a set of instructions and scripts your agent will follow, and it can run code on your machine. Read the SKILL.md and any scripts first — this listing is not a security review.
