Claude Octopus Setup Guide: Make AI Models Challenge Your Code
Install Claude Octopus, run a focused council, and use practical prompts for building, code review and security checks.
Claude Octopus brings additional model perspectives into a Claude Code workflow. This guide walks you through installing it, checking which providers are available, and giving the council a concrete decision to challenge. Then you can use focused prompts for a build, a code review and a security pass.
The useful part of AI disagreement is the evidence it produces: a missed requirement, a failing test or a design tradeoff you can act on. More opinions alone do not establish a tenfold improvement. Judge the result against the same acceptance criteria you would use for any other implementation.
Install and check the setup
Start with a working Claude Code installation. Octopus is an independent MIT licensed project. The plugin can start with Claude alone; an independent provider must be configured before you can expect a cross-provider comparison. API usage or subscription limits still apply.
Run these two commands in your terminal, outside an active Claude Code session:
claude plugin marketplace add https://github.com/nyldn/plugins.git claude plugin install octo@nyldn-plugins
Open Claude Code in a small project you know well. Run the setup command inside that session and follow its provider configuration steps:
/octo:setup
Octopus stays dormant until you invoke an /octo:* command. If you only ask an ordinary Claude question after installation, that does not demonstrate that multiple providers contributed. Confirm the available providers before your first council run.
