Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

Leverage Claude Opus 4.5's extended thinking capabilities for deep reasoning, complex analysis, and multi-step synthesis. Use when problems require thorough deliberation before response.

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'opus-extended-thinking' ] || [ -L ~/.agents/skills/'opus-extended-thinking' ]; then echo 'A skill folder named opus-extended-thinking already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/frankxai/agentic-creator-os' "$d" && git -C "$d" checkout --quiet '9dc9c9592ba6be55de0662b6c0b65ec01b08c775' -- '.claude/skills/opus-extended-thinking' && mkdir -p ~/.agents/skills && cp -R "$d"/'.claude/skills/opus-extended-thinking' ~/.agents/skills/'opus-extended-thinking' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'opus-extended-thinking' ~/.claude/skills/'opus-extended-thinking' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
