# GCP Workload Identity Federation with GitHub Actions

Configures GCP Workload Identity Federation (WIF): creating Workload Identity Pools and Providers, configuring attribute condition mappings (repository matching), and acquiring short-lived GCP tokens in CI.

## When to Invoke
Invoke this skill whenever you need to:
- setup gcp workload identity github actions
- eliminate gcp service account key
- configure wif gcp

## Execution SOP & Rules
1. Create Workload Identity Pool and OIDC Provider linked to https://token.actions.githubusercontent.com.
2. Map attributes: google.subject=assertion.sub, attribute.repository=assertion.repository.
3. Bind IAM role WorkloadIdentityUser on service account to principalSet matching repository.
4. In GitHub Actions: use google-github-actions/auth@v2 specifying workload_identity_provider and service_account.

## Verification Checklist
- Run local linting, syntax validation, and type-checks before reporting completion.
- Ensure all created or modified files adhere to workspace boundaries and avoid uncommitted secrets.
- Verify tests or build commands exit cleanly with return code 0.
