A toolkit for the work in front of you

• Start with your task. The questions and checks are already written into each method, ready to reuse across conversations.
• Find a useful angle. Draw on methods for comparing options, evaluating evidence, exploring assumptions and planning ahead.
• Make it your own. Read every procedure, study its examples and adapt the open-source material to your work.

See it in a task

Try a request like this after setup:

We were about to buy a hosted tool, but now the workflow has to run offline. Should we buy, build our own, or handle it manually for now?

For a decision like this, trade-off analysis provides a reusable sequence: identify the requirements, compare viable options, separate known facts from assumptions, and explain what would change the recommendation. The method supplies that structure alongside your everyday request.

Claude Code — Apple-silicon Mac

You need Node.js 20+, the Claude CLI and a signed-in Claude account. This works with terminal Claude Code and local Code in Claude Desktop. Run in Terminal:

npx --yes opensocrates@1.5.3 install --host claude
npx --yes opensocrates@1.5.3 diagnose --host claude

Confirm enabled: true, integrity: verified and registration: confirmed. Review any project trust prompt, then start a fresh local session. Visual setup guide

Codex — Apple-silicon Mac or Windows x64

You need Node.js 20+ and Codex. The native runtime comes with the package. Run in Terminal on Mac or PowerShell on Windows:

npx --yes opensocrates@1.5.3 install --host codex
npx --yes opensocrates@1.5.3 status --host codex

Open interactive Codex and enter /hooks in its input field. Review and approve the seven OpenSocrates hook definitions you trust, then start a fresh conversation. Visual setup guide

To update an existing Codex installation:

npx --yes opensocrates@1.5.3 update --host codex

Antigravity — Apple-silicon Mac or Windows x64

You need Node.js 20+. Choose a workspace and replace the example with the full path of a folder that already exists. Run in Terminal on Mac or PowerShell on Windows:

npx --yes opensocrates@1.5.3 install --host antigravity --workspace "/absolute/path/to/workspace"

On Windows, use a quoted local-drive path such as "C:\Work\Reading Workshop". For a global setup, omit --workspace. Pick global or workspace installation for a given project, then start a fresh conversation. Confirm the skill and rule

Setting up with an agent? Use the setup request or the current installation guide. Select each app with its named --host option; the default and --host all select Codex.
