gke-workload-identity SKILL.md skillB
gke-workload-identity from gke-labs/kube-agents is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add gke-labs/kube-agents/gke-workload-identity@v1.0.1Pins v1.0.1 in mdr.lock. Pin the fingerprint instead.

Configures and diagnoses Workload Identity Federation for GKE authentication failures for Pods (403 "iam.serviceAccounts.getAccessToken" / permission denied, "could not find default credentials", or GKE metadata server unreachable) by verifying cluster and node-pool Workload Identity configuration, the Kubernetes ServiceAccount (KSA) to IAM binding (direct principal binding and legacy Google ServiceAccount impersonation), target-resource IAM roles, and gke-metadata-server health.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# GKE Workload Identity Federation Troubleshooting Skill
Use this skill to systematically diagnose why a Pod using **Workload Identity
Federation for GKE** cannot authenticate to Google Cloud APIs. Typical symptoms:
- `HTTP/403 ... Permission 'iam.serviceAccounts.getAccessToken' denied on
resource`
- `google.auth.exceptions ... could not find default credentials` /
`ComputeEngineCredentials cannot find the metadata server`
- API calls that unexpectedly use the node's default Compute Engine service
account instead of the workload's identity.
## Read-only boundary
This skill is **diagnostic and non-interactive**. It only **reads** cluster,
IAM, and logging state and **proposes** fixes as commands or GitOps manifest
changes for a human to apply. It must **never** create or modify IAM bindings,
KSA annotations, node pools, or clusters automatically. When evidence is missing
or the fix requires a privileged change, summarize findings and hand off to a
human (see Step 7).
## Output discipline (apply to every conclusion)
When you report a diagnosis, always:
1. **Name the single most-likely root cause** (not an open-ended list of
possibilities).

How to install
mdr add gke-labs/kube-agents/gke-workload-identity@sha256:c7d8545b63b6823aThe line at the top of this page pins the label v1.0.1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
