Products

Two products, one way of working.

Open source · MIT

Agent Kit

A reusable Agent-Driven Development methodology: 23 process skills, templates, specs and tooling, extracted from production use and adoptable in any project by any coding agent.

Agent Kit feature pipeline: idea, ticket, specify, implement, verify, deliver, record

  • End-to-end pipeline

    Idea → ticket → specify → implement → verify → deliver → record.

  • Adversarial verification

    Claim → extract → doubt → reconcile before anything ships.

  • TDD & 5-axis review

    RED→GREEN discipline and a five-axis code review gate.

  • Any coding agent

    Claude Code, Codex, Gemini or others install it from one skill.

Services

Technology consulting & digital transformation.

We advise using the same process we use to build our own products.

  • Technology strategy & architecture

    Assess your current stack, design the right-sized architecture and avoid over-engineering.

  • Digital transformation roadmap

    Prioritised, measurable steps to digitise operations, from discovery to rollout.

  • AI-assisted engineering

    Introduce coding agents to your team with a disciplined workflow, powered by Agent Kit.

  • MVP & product engineering

    From idea to a running product on React/Next.js, Go, PostgreSQL and Redis.

  • Game & real-time systems

    Server-authoritative game backends, turn-based and idle mechanics, live-ops tooling.

  • AI agents & LLM integration

    Safe agent design with bounded capabilities, validation, fallbacks and cost budgets.

How we work

  1. 01

    Discover

    Understand goals and constraints.

  2. 02

    Specify

    Write the spec and the tests first.

  3. 03

    Build

    Agents implement, humans steer.

  4. 04

    Verify

    Adversarial checks before delivery.

About

Small team, real output.

MrDnD.dev was founded by Duong Nguyen. The team is currently 1–10 people and works agent-first: agents handle implementation, humans own direction and quality.

FAQ

Frequently asked questions

What is MrDnD.dev?

MrDnD.dev is a Vietnamese tech startup founded by Duong Nguyen with a team of 1–10 people. We work on three things: Agent Kit (an Agent-Driven Development kit), HeroGame (a turn-based idle wuxia MMORPG) and technology consulting and digital transformation services.

What is Agent Kit and how do I use it?

Agent Kit is an open-source (MIT) Agent-Driven Development methodology with 23 process skills, templates, specs and tooling. Add it to any project, then have a coding agent such as Claude Code read the agent-kit-init skill to set up the workflow from ticket to specification, implementation, verification and delivery.

What is Agent-Driven Development (ADD)?

ADD is a way of building software where AI coding agents do most of the implementation inside a disciplined process: clear specs, TDD, multi-axis review, adversarial verification and recorded decisions. Humans set direction and stay accountable.

What is HeroGame?

HeroGame is a turn-based idle wuxia MMORPG inspired by Thiên Địa Anh Hùng (Hải Thiên Anh Hùng Truyện, Seasky Netjoy). It features the Five Elements, 12 Chinese hours, seven sects and a server-authoritative backend, and is currently in development.

What consulting services does MrDnD.dev offer?

Technology strategy and architecture, digital transformation roadmaps, AI-assisted engineering, MVP and product engineering, game and real-time systems, and AI agent integration. Email hello@mrdnd.dev to discuss your needs.
