# RStack SDLC

> A framework-independent, governed AI software-delivery harness for coding agents.

## What is RStack?

**RStack SDLC** is a portable AI-SDLC framework developed by Richardson Gunde. It gives AI coding agents a repeatable, governed software delivery lifecycle instead of ad-hoc prompting.

## The RStack lifecycle

```
clarify → plan → spec → approve → build → validate → release-readiness → learn
```

RStack enforces this lifecycle so AI agents behave like a productive software team — not a single chatbot.

| `.rstack/runs/`       | Generated run state — specs, approvals, traceability, evidence, metrics |

## Why RStack?

One-shot coding agents often fail because they skip process. They code before requirements are clear, over-edit unrelated files, pass work without testing, or forget previous mistakes.

RStack fixes this by making the agent follow an explicit lifecycle with contracts and validation at every stage.

<Note>
  RStack ships with a native **Pi adapter** today, but the framework is portable. The core assets are Markdown/JSON-compatible and can be used from Claude Code, Codex CLI, Gemini CLI, or any agent harness.
