OpenCode GitHub Actions

A GitHub Action for OpenCode with pinned actions/cache and OpenCode versions.

This action is a fork of the official action. It updates actions/cache, improves the OpenCode installation logic, pins the OpenCode version, and verifies the SHA256 checksum on every run, whether the cache is hit or missed.

Important

This action uses ${{ github.token }} in the Resolve opencode release metadata step only so gh can fetch OpenCode release metadata. By default, the token is not exposed to OpenCode itself. If you want OpenCode to access the token, for example to create issues, pass it through the step environment as GH_TOKEN: ${{ github.token }}.

Both actions/cache and OpenCode are updated automatically by Renovate with minimumReleaseAge set to 1. Use this action with a pinned Git SHA, and make sure you have a dependency management tool like Renovate or Dependabot enabled so you do not miss updates.

How to use

Use it the same way as the official action.

First, get the latest Git SHA for this repo:

curl -fsSL "https://api.github.com/repos/xlionjuan/opencode-github-actions/branches/main" | jq -r '.commit.sha'

Then replace anomalyco/opencode/github@latest with xlionjuan/opencode-github-actions@{GIT SHA}, using the value from the previous step:

Warning

You should NEVER use latest ! Check Upgrade best practices.

The # main is necessary to let managers knows which branch it should tracking.

- name: Run opencode
  uses: xlionjuan/opencode-github-actions@{GIT SHA} # main
