keyvault-csi-driver

keyvault-csi-driver is a skill for Claude Code, Codex from julianobarbosa/claude-code-skills. It costs 53 tokens per session (2,392 once invoked), scanned A, original, MIT.

A guide for connecting Azure Key Vault, Microsoft's service for storing secrets, to Kubernetes through the Secrets Store CSI Driver. The connection lets applications use secrets held in Key Vault.

In plain words
What is it for?
Use it to create SecretProviderClass resources, mount Key Vault secrets in pods, copy them into Kubernetes Secrets, and investigate permission errors.
Why use it?
It avoids placing sensitive values directly in application configuration and helps troubleshoot access and secret-sync problems.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is ./scripts/grant-keyvault-permissions.sh.

Good fit Use it to create SecretProviderClass resources, mount Key Vault secrets in pods, copy them into Kubernetes Secrets, and investigate permission errors.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Code enumerates, copies, or searches environment variables for secrets. Bulk environment access can collect credentials unrelated to the skill's stated purpose.
    Fix: Read only explicitly required environment variables by name. Avoid enumerating or copying the full environment, and never log or transmit credentials to untrusted destinations.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

keyvault-csi-driver scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/create-keyvault-secret.sh, scripts/diagnose-csi.sh, scripts/grant-keyvault-access.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Azure Key Vault CSI Driver Skill

Overview

This skill provides guidance for integrating Azure Key Vault with Kubernetes using the Secrets Store CSI Driver. All sensitive data in the your organization clusters is stored in Azure Key Vault and accessed via the CSI driver.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
