── The library

Built in the open.
Open to everyone.

deciqAI is the advisory engine for accounting firms. This is the open half of it: the skills wired into every agent, plus the founder and small-business guides we wrote along the way.

Free. No login. Bring it to whatever tool you already use.

237 skills for thinking, managing, and operating — wired to every agent.

The mental models, management frameworks, and operating patterns we use to build deciqAI's decision and analysis layers. Each one written as a process an agent can run, not as a textbook entry.
