About this app

Agent Smith – Unified Guidance for Your AI Coding Assistants Agent Smith keeps your AI coding assistants on the same page. Craft one single master brief, enrich it with platform‑specific notes, then instantly export your AGENTS.md, CLAUDE.md, and GEMINI.md files to the project root where your AI Agents expects them to be. Agent Smith comes complete with automatic syncing whenever the blueprint evolves. Whether you collaborate with Claude, Codex/OpenAI, Gemini, or all of the above, Agent Smith makes sure all AI agents receive the context they needs to ship quality code. ***Why Developers Love Agent Smith*** - Single Source of Truth: Write your project overview, architecture details, coding standards, and style rules once. Agent Smith mirrors them across your AGENTS.md, CLAUDE.md, and GEMINI.md files. - Per-Agent Customization: Add tailored instructions for Anthropic's Claude, OpenAI's Codex, and Google's Gemini in dedicated side panels. Those extra instructions are appended only to the corresponding agent's .md target. - One-Click Export: Choose your project root and generate the full configuration set with a single press. Export history is tracked so you always know where the latest files live. - Live Auto-Sync: Leave the app running while you edit the master file in your editor. Agent Smith watches for changes and refreshes every derived file automatically. - Thoughtful Defaults: Built-in templates prompt you to capture the frameworks, databases, build tools, testing philosophy, and deployment quirks your AI teammates need to know. - macOS Native Comfort: Enjoy a clean SwiftUI interface with adjustable panels and keyboard shortcuts (⌘⌥S toggles the sidebar) - Built for Multiple Projects: Reuse Agent Smith across repos and teams; the master instruction file lives right beside your code, ready for version control. Perfect for: - Teams adopting AI pair-programming agents and needing consistent guidance. - Solo developers juggling multiple assistants or switching between different AI providers. - Engineering leaders documenting architecture decisions, tooling expectations, and coding standards for AI collaborators. With Agent Smith as your source of truth for AI instructions, each export keeps Claude, Codex/OpenAI, and Gemini aligned so you spend less time repeating instructions and more time shipping great software!

Baseline captured. Growth appears after the crawler observes a changed rating count.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
