Pluggable role definitions for AI coding agents — one command turns Claude Code / Cursor / OpenCode / Codex into a specialized professional

AgentBrief

One command turns your AI coding agent into a domain specialist.

Website · Catalog · npm · 中文

Your Claude Code, Cursor, OpenCode, or Codex gives generic answers because it doesn't know your domain. AgentBrief fixes that — install a brief and your agent gains real expertise: security auditing, code review, product specs, growth hacking, and more.

npx agentbrief use fullstack-engineer
# Your agent now enforces strict TypeScript, follows Next.js conventions,
# builds accessible UIs, and reviews PRs like a staff engineer — 9 skills in 1 command

Before vs After

WITHOUT a brief:
  You: "Review this code for issues"
  Agent: "The code looks good overall. Consider adding error handling."

WITH security-auditor brief:
  You: "Review this code for issues"
  Agent: "CWE-89 CRITICAL at line 23: SQL injection via string concatenation.
         Attack vector: attacker injects arbitrary SQL through userId param.
         Fix: const query = 'SELECT * FROM users WHERE id = $1';
              await db.query(query, [userId]);"

Install

npm install -g agentbrief
# or
pnpm add -g agentbrief
