120 free AI personas. One GitHub repo. Here's what's actually inside — and how to use it properly with Claude Code subagents. ------------ Agency Agents repo → https://github.com/msitarzewski/agenc... For business enquiries: [email protected] ------------- Agency Agents is an open-source collection of structured AI personas for engineering, marketing, design, QA, sales, spatial computing, and more. MIT licensed. Actively maintained. 29,000+ stars. Most coverage has been surface-level. In this video we go deeper: we open the actual agent files, test whether the output difference is real (same task, same model, generic prompt vs. specialized persona), and walk through the full Claude Code subagent setup — how to install agents to ~/.claude/agents/, how Claude Code auto-delegates to the right specialist, how to run parallel subagents with isolated context windows, and how to add persistent memory that builds knowledge of your codebase across sessions. We also cover how these agents work across Cursor, Aider, Windsurf, Gemini CLI, and OpenCode — and give you the honest picture on where quality varies and why customizing beats using them out of the box. --------- ⏱️ VIDEO TIMESTAMPS: 0:00 — Intro 0:25 — Agenda 0:44 — What's Agency Agents? 1:18 — What's inside .md 1:46 — Testing (70% improvement) 4:04 — Setting up Agency Agents in Claude Code 5:42 — Claude Code sub-agent setup 7:41 — Honest limitations + verdict
