 # /deep-project, a Claude Code plugin      > **Blog posts:** > - [The Deep Trilogy](https://pierce-lamb.medium.com/the-deep-trilogy-claude-code-plugins-for-writing-good-software-fast-33b76f2a022d) - How the three plugins work together > - [What I Learned](https://pierce-lamb.medium.com/what-i-learned-while-building-a-trilogy-of-claude-code-plugins-72121823172b) - Technical lessons from plugin development `/deep-project` transforms vague, high-level project requirements into well-scoped planning units through AI-assisted interview and decomposition. It ensures you've thought through every major component of the software you want to build and properly scoped them for thorough planning through [`/deep-plan`](https://github.com/piercelamb/deep-plan). This plugin is the first step in the deep planning pipeline. After decomposition, each unit can be fed to [`/deep-plan`](https://github.com/piercelamb/deep-plan) for comprehensive planning with research, external LLM review, and a TDD approach. I built this after the first time I wanted to put a vague, broadly scoped software project through `/deep-plan`. I realized that at a certain level of broadness, for e.g., "Build me an app that does x y and z", that the optimal use of `/deep-plan` would be to split that vague idea into its distinct, major components and `/deep-plan` each of them. `/deep-project` is the plugin that allows you to give it very broad, vague ideas and have it tease out context and form the components that should each be `/deep-plan`ned.
