…unners Non-ephemeral self-hosted runners retain ~/.claude state across workflow runs. On the second run, 'claude plugin marketplace add' exits 1 with "already installed" and the action fails before any plugins are installed. Capture stdout/stderr in addMarketplace (mirroring to parent process so output remains visible), and resolve instead of rejecting when the output contains "already installed". Any other non-zero exit still propagates as an error. Tests: update assertions for the new stdio tuple, add two new cases covering the idempotent skip and non-matching failure passthrough. Fixes anthropics#1057. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Fixes #1057.
Problem
Non-ephemeral self-hosted runners (e.g. GCP MIGs) retain
~/.claudestate across workflow runs. On the second run,claude plugin marketplace addexits 1 with:The action treats any non-zero exit as a hard failure and stops before installing any plugins.
Fix
addMarketplacenow captures stdout/stderr (while still mirroring it to the parent process so logs remain visible), and resolves instead of rejecting when the output contains"already installed". Any other non-zero exit still propagates as an error. Makes the marketplace install step idempotent on persistent runners.Tests
