Repo Prompt helps AI models understand your codebase without wasting tokens on irrelevant code. Context Builder analyzes your project and selects the files and functions needed for your task, building dense context that fits in model limits. It works with your existing AI subscriptions (Claude MAX, ChatGPT Plus, Gemini) — no extra API costs. The MCP server turns Repo Prompt into a backend for Claude Code, Cursor, and Codex, giving them context analysis and discovery they can't do on their own.

Repo Prompt is like a superskeleton for creating better prompts within specific repos or projects.
It'll help you produce refined prompts so that when you hand off to your coding agent of choice, it'll get the done more efficiently and intentionally.
Enjoy!
Repo Prompt
Repo Prompt lets you build precise context from your codebase so reasoning models actually understand what you’re working on.
I’ve been building it for over a year now. With MCP and CLI support, it fits into any agent workflow — Claude Code, Codex, Cursor, whatever you use.
The /rp-build command automates the whole loop: it researches your codebase, builds a plan, and hands off to your agent with the right context already loaded.

Repo Prompt
@curiouskitty Hey! So the big difference with plan mode in existing tools, is that Repo Prompt's context builder operates earlier in the flow. It splits up planning and research into separate tasks.
Context builder's job is to navigate your repo using an agent like claude code or codex directly (the app handles orchestration using cli headless modes), and it will then isolate the relevant files, and carve out the most relevant sections of those files. The discovery agent also writes you an optimized prompt that includes your task, and information about the codebase architecture, and class relationships.
The result is a dense context prompt that can be used for planning. If you've ever tried to use reasoning models like GPT 5.2, one of the challenges is getting them to spend as many reasoning tokens as possible on analysis, instead of navigation. This gets you the best possible way to prompt those models to really pull the frontier of intelligent architectural planning forward.
I invite you to read how some of the other commenters here actually use the app. It's highly automated and with the cli or mcp, it can fit into your existing cursor or claude code workflows, and enhance their built in planning and navigation.
The process I described above, is automated with a convenient slash command now. You can simply type /rp-build, and Repo Prompt will return with codebase analysis and the plan from that dense context prompt, for your agent to get to work with.
I rarely comment here but this one's worth it.
I usually have 5-10 RepoPrompt windows open at any given time; one per project I'm context-switching between. It's become essential to how I work with AI coding tools.
The CLI/MCP Server is the killer feature for me. I've built autonomous multi-model review loops and context export workflows on top of it. The CLI lets agents coordinate reviews without me babysitting.
If you're building AI coding workflows, these features turn RepoPrompt from a great GUI into actual infrastructure you can automate against. Congrats on the launch Eric!
I’ve been actively using Repo Prompt for almost a year now, and it’s made it much easier to give LLMs the right context from a codebase without overloading them. Being able to select only the files that matter and generate a clean prompt saves time and tokens. It fits nicely into an ai assisted coding workflow and feels practical rather than gimmicky.
One of the best additions to my dev workflow. It is a great tool to rapidly improve the precision of your development with coding agents - saving you time and money. One of the best features of this app is the rapid development lifecycle and how close Eric is to the community of users, and he's both opinionated and openminded... Join the discord, and help guide the tool's development.

I've been using Repo Prompt for over a year now, and it's become an essential part of my daily development workflow.
As a founder building multiple B2B SaaS products, the ability to quickly assemble the right context for AI assistance has been a game-changer. Whether I'm working on backend Rails projects or integrating AI features, Repo Prompt saves me countless hours every week.
Here's a kept secret: pairing Repo Prompt with GPT-5 Pro (with full context) is incredibly powerful for architectural planning. The combination of precise context selection and advanced reasoning lets you think through complex system designs before writing a single line of code.
Highly recommended for any serious developer working with AI tools. This isn't just a productivity boost—it's become foundational to how I build software.
This is my workflow
