Gke Storage

What it does

When your agent uses it

• Configuring GKE storage
• Database administration
• Replication strategies outside volume provisioning context

Example prompts

• “Use the gke-storage skill to manage GKE storage, including PVCs, PersistentVolumes, and Filestore”
• “/gke-storage”

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

1. 1Always enable volume expansion: Set allowVolumeExpansion: true on all
2. 2Use regional PDs for production: replication-type: regional-pd
3. 3Use WaitForFirstConsumer: Ensures the PV is provisioned in the same
4. 4Choose the right disk type: pd-ssd for databases, pd-balanced
5. 5Use Filestore for shared access: When multiple pods need to read/write
6. 6Use GCS FUSE for data pipelines: Mount buckets directly for ML training
7. 7Back up PVCs: Use Backup for GKE (see the gke-backup-dr skill) to

What it can do on your machine

Read from SKILL.md and the folder at commit 8a1ac05. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Shell commands in SKILL.md call:

  • kubectl

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  No URLs in SKILL.md. Its commands use kubectl, which can reach the network depending on how they are called.

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Gke Storage loads about 1.8k tokens when it runs. Until then it costs about 112 tokens; SKILL.md has 552 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~112

When it runs · the whole SKILL.md, loaded when a task matches

~1.8k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description

Manages GKE storage, including PVCs, PersistentVolumes, and Filestore. Use when configuring GKE storage or creating PVCs. For GCS FUSE mounts, use google-cloud-storage-fuse. For diagnosing storage failures (volume attach/mount errors, disk performance/node storage pressure, or Cloud Storage FUSE OOM), use gke-storage-troubleshooting. Don't use for database administration or replication strategies outside volume provisioning context.
