Is the Octopus Architecture skill free?

Yes. The skill itself is free from nyldn/claude-octopus. SkillProof publishes the install command and an independent test verdict at no cost.

How do I install Octopus Architecture?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Octopus Architecture with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Test report

Verdict: Tested · Didn't pass
Tested: Jul 13, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · 5a435db

The card's install runs clean but the skill is completely non-operational: ~/.claude-octopus/plugin (the scripts SKILL.md depends on) is never provisioned by the verbatim install, and even against a fully-installed upstream repo the mandatory 'spawn backend-architect' command is invalid CLI syntax (a persona name where an agent-type is required), erroring exit 1 with zero output regardless of Codex/Gemini availability — directly contradicting the README's 'zero providers needed' claim. Confirms a prior SkillProof finding on this skill.
