Build a Claude Code subagent.
Keep the blank cheque.

A subagent is a focused AI helper for one job. Choose what it should do and what it may access; Sirrius Atlas creates the file and explains every choice.

  • Decide whether a subagent is actually useful
  • Start with least-privilege recipes
  • Check an existing definition for common risks

Check first. Trust second.

Before you use an Atlas resource.

What the publication covers, how it relates to Sirrius Office, and where its evidence boundaries sit.

01What is Sirrius Atlas?

Sirrius Atlas is a free collection of clear, practical guides for building with AI. It explains what tools and commands do, when to use them, what to watch out for, and where the information came from. It is published by Sirrius Office Inc.

02How is Sirrius Atlas different from Sirrius Office?

Sirrius Atlas publishes free working knowledge. Sirrius Office is the company that designs and builds apps, internal tools, and automation for clients. The guides demonstrate the research and operating standards behind that work.

03Are the Sirrius Atlas resources free?

Yes. Sirrius Atlas resources are free to browse and use. Some complete offline downloads ask for an email address and explicit permission to send resource updates; permission for Sirrius Office service emails is a separate, optional choice.

04Is Sirrius Atlas only for experienced developers?

No. Sirrius Atlas is designed for new AI builders, vibe coders, business operators, and experienced developers. Each resource keeps practical explanations, cautions, and source status beside the commands so you can understand what to use and why.

05Is Sirrius Atlas affiliated with the AI vendors it covers?

No. Sirrius Atlas is an independent publication and is not affiliated with or endorsed by the vendors covered in its field guides. Product names and marks belong to their respective owners.

06How are claims checked?

Official vendor documentation supports product facts. Public secondary web material is used to discover practical ideas, which remain labelled as patterns or watchlist notes unless they can be independently corroborated. Automated reports cannot edit or deploy the website.

The free resources show how we think.
The systems show what we can build.

Sirrius Office designs apps and automation that remove repetitive work, improve client service, and connect the tools a business already uses—with fixed pricing and no vendor lock-in.
