Agency Agents: AI Specialist Team for Claude Code

Agency Agents turns Claude Code into a full department of specialists — a frontend wizard, a security reviewer, a Reddit community manager — instead of one generalist juggling everything at once. It’s free, open source, and has quietly become one of the most-starred agent-persona projects on GitHub.

250+ personas, not one overworked generalist

Each agent is a markdown file with a real identity — workflow, success metrics, communication style, common failure modes to avoid. Not a one-line “act as a developer” prompt. Born from a Reddit thread and months of iteration, the roster now spans 16 divisions: engineering, design, marketing, sales, product, security, testing, finance, and more.

Activate one mid-session — “activate Frontend Developer mode and help me build a React component” — and Claude Code picks up that persona’s instructions for the rest of the session. Ask for a security pass instead, and you get the Security Reviewer’s checklist and tone, not a generic once-over.

Works everywhere, not just Claude Code

The same roster installs into Cursor, Codex, Gemini CLI, Windsurf, Aider, and a growing list of other AI coding tools. A native desktop app for macOS, Linux, and Windows browses the whole roster and installs with a click — no cloning, no scripts, and it auto-updates as new agents land.

That portability matters more than it sounds. Teams that mix editors don’t have to maintain a different prompt library per tool, and switching tools later doesn’t mean rebuilding your setup from scratch.

Pick a division, not the whole roster

You don’t have to install everything. Grab just engineering and security, or just marketing, or one specific agent by name. The install wizard filters by division or by individual agent, so a solo developer’s setup looks nothing like a marketing team’s — and neither is stuck carrying agents they’ll never use.

The roster’s growth reflects how much friction this removes: well over a hundred thousand stars and tens of thousands of forks in a relatively short window. Forking the repo to trim it to just the agents a team actually uses is a common pattern in the community.

Who actually needs this

Indie developers and small teams get the clearest win — the roster stands in for hires you can’t afford yet. But it holds up for larger teams too: everyone activating “Security Reviewer” gets the same checklist and tone, instead of every developer improvising their own prompt for the same task.

It’s also just a good reference even if you never install a single file — each agent doubles as a written playbook for that role, worth skimming even if you’d rather write your own prompts by hand.

Get it running

Fastest path: agencyagents.app, or on a Mac:

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

Prefer the terminal:

./scripts/install.sh --tool claude-code --division engineering,security

Full install matrix and the complete agent list live in the repo’s README.

Agency Agents is worth a look the moment Claude Code starts feeling stretched thin across unrelated tasks in one session. Star it, activate one agent, see what changes.
