Fix git checkout for Slack notify workflow#996
Merged
Conversation
claude-code-action restores trusted .claude/.mcp.json config from the base branch via git before running Claude, even in agent mode, which needs a git working tree. Add a checkout step; the default ref on pull_request_target is the base branch, not the PR head, so this stays consistent with never running PR-supplied code.

Description
Follow-up to #995. Removing
id-token: write(#994) fixed Anthropic-auth-unrelated OIDC, but the next run failed withfatal: not a git repository. claude-code-action'srestoreConfigFromBasestep unconditionally runsgit fetch/git checkoutagainst the base branch to restore trusted.claude/.mcp.jsonconfig before Claude runs, even in agent mode, and that needs an actual git working tree. This workflow never ranactions/checkout, so there was no.gitdirectory.Added a checkout step.
pull_request_target's default checkout ref (no explicitref:) is the base branch's HEAD, not the PR head, so this stays consistent with the workflow's existing security model: no PR-supplied code ever lands in the workspace.Type of change
