## Summary Follow-up to #42. The `reusable-opencode.yml` note records that a SHA pin covers only the composite wrapper, because `action.yml` `curl`s the latest opencode CLI at run time regardless of the pin. That gap now has a proposed upstream fix — [anomalyco/opencode#39147](anomalyco/opencode#39147), which runs the installer bundled at the pinned ref and adds a `version` input passed through to it. This points at it and records the action to take here if it lands: bump the pinned SHA and set `version` in the reusable workflow. Would have ridden in #42, but that merged first. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-authored-by: Claude Opus 5 <noreply@anthropic.com>

Closes #39163
Type of change
What does this PR do?
Pinning the action to a commit SHA didn't pin anything that runs: the installer was fetched from opencode.ai at run time, and the CLI was always the latest release. The version resolved from the releases API only fed the cache key — it was never passed to the installer.
Two changes:
curl -fsSL https://opencode.ai/install | bash→bash "$GITHUB_ACTION_PATH/../install". The whole repo is checked out when a subdirectory action runs, so./installis already there at the pinned ref.versioninput, passed to the installer asVERSION. The installer already reads it.Two details that aren't obvious from the diff:
bash, notsh—./installis#!/usr/bin/env bashand uses[[ ]].resolved(given to the installer) separately fromversion(cache key). They differ when the API lookup fails:versionkeeps the existinglatestplaceholder, but sendingVERSION=latestto the installer would make it look for a release taggedvlatest, soresolvedis left empty and the installer picks latest itself, as before../installis sha256-identical to what opencode.ai serves today, so this changes where the script comes from, not what it does.How did you verify your code works?
Ran both paths on an
ubuntu-latestrunner against this branch.With
version: "1.18.6"(latest was 1.18.7):Without the input — same as before this PR:
I also checked
$GITHUB_ACTION_PATH/../installresolves on a runner before writing this: for a subdirectory actionaction_pathis_actions/<owner>/<repo>/<ref>/github, so../installlands on the repo-root script.To reproduce: point a workflow at this branch with and without
version, and checkopencode --version.Screenshots / recordings
n/a — not a UI change.
