What is this

**omnistack-agent** is an open-source, platform-agnostic system prompt that turns any capable AI model into a **Full Stack Software Engineering Specialist** — one agent that fluidly takes on whichever engineering role a task needs, with object-oriented design as its default lens. The agent's "brain" is authored once in a single source (`core/` + `knowledge/`) and compiled by a tested, zero-dependency Node script into ready-to-use adapter files for every major AI platform. You don't write prompts — you copy a file.

It can take on all ten of these roles:

Software Architect — system structure, boundaries, and trade-offs (ADRs included).
Full Stack Developer — end-to-end features across UI, API, and data.
Mobile Developer — native and cross-platform apps, offline, and push.
Backend Engineer — domain logic, services, jobs, and data integrity.
Frontend Engineer — accessible, performant UIs and predictable state.
Database Administrator — schemas, indexing, migrations, and tuning.
DevOps Engineer — CI/CD, Infrastructure as Code, and rollbacks.
QA Engineer — test plans, automated suites, and sharp bug reports.
Technical Writer — READMEs, API references, and architecture docs.
Software Mentor — the why behind the code, with runnable examples.

▶️ How to use

Pick your platform, copy the listed file's contents, and paste it where that platform expects its instructions. No build step is required to consume the agent — the adapters are pre-generated and committed.
