What is it?

The Agency is a library of AI agent definitions, each written as a specialist persona with a defined identity, working processes, deliverables and success metrics. The roster is grouped into divisions such as Engineering, Design, Marketing, Sales, Product, Testing, Security, Support and Spatial Computing, with entries covering roles like frontend developer, backend architect, code reviewer, SRE and penetration tester.

The repository includes shell scripts that convert these agent files into formats used by many AI coding and assistant tools, including Claude Code, Cursor, Aider, Windsurf, Codex and Gemini CLI. The installer can target a specific tool and filter by division, individual agent, or a predefined team, and supports a dry-run mode. A separate desktop app is also available for browsing and installing the roster.

Each agent file can be used directly as an installed assistant persona or simply read and adapted as a reference prompt for building your own agents.

Key features

  • 01Covers over a dozen divisions, from engineering and design to marketing, sales and security.
  • 02Installer script targets specific AI tools such as Claude Code, Cursor and Gemini CLI.
  • 03Filter installs by division, individual agent or predefined team.
  • 04Dry-run mode previews what an install will do before writing files.
  • 05Each agent file defines identity, workflows, deliverables and success metrics.

Use cases

  • Adding a set of specialist personas to Claude Code or Cursor for a software project.
  • Borrowing prompt structure and workflow ideas to write your own agent definitions.
  • Assembling a small team of agents for a startup MVP using a predefined runbook roster.

Quick start

  1. 1

    Install the desktop app on macOS via Homebrew

    brew install --cask msitarzewski/agency-agents/agency-agents
  2. 2

    Or install all agents into Claude Code with the script

    ./scripts/install.sh --tool claude-code

Things to know

  • The one-line Homebrew install is for macOS only; other platforms need the release download or the scripts.
  • The agents are prompt files rather than standalone software, so their value depends on the AI tool you use.
