How to use Archcore.

A short interactive walkthrough with five branches you can pick from the entry screen. Each branch is 3-5 steps with copy-pasteable commands, expected output, and a one-line note on what just happened. Branches that have both a plugin and a CLI flavor carry a Plugin / CLI toggle you can flip on every step.

Same product, two entry points. The Plugin is the recommended runtime for Claude Code, Cursor, and Codex CLI — seven /archcore slash commands with automatic context injection. The CLI is the core context layer for any MCP-aware agent — finer control, scriptable in CI, the way to integrate with Copilot, Gemini CLI, OpenCode, Cline, and the rest.

What the five branches deliver. How to install Archcore — pick Plugin or CLI, walk through install and verification. Quick start in your project — your first useful command after install on a fresh repo. I have an idea, no context yet — turn a plain-English idea into PRD → spec → plan. Document existing code — capture what already lives in code as decisions, rules, plans, and guides. Solve tasks with existing context — load the right docs before editing, audit drift after.
