Workaround Opencode with Claude Code Pro/Max plan

patch-opencode-claude-code-plan.md

Anthropic blocks third-party tools from using your Claude subscription, but you can work around it quite simply

This is for OpenCode only, which is the tool I'm using now.

Clone OpenCode

git clone git@github.com:anomalyco/opencode.git && cd opencode

Install dependencies

bun install # if you don't have bun, install with curl -fsSL https://bun.com/install | bash

Apply the patch that works around it

curl https://gist.githubusercontent.com/brunocroh/c5e986a25d58de6f43952bc0847339f8/raw/3db4f7c00959214ada331f283341ca1e0873ce7d/patch.txt | git apply

Build OpenCode

./packages/opencode/script/build.ts --single

Run it

./packages/opencode/dist/opencode-<platform>/bin/opencode
