helm-validator

helm-validator is a skill for Claude Code from akin-ozer/cc-devops-skills. It costs 26 tokens per session (8,399 once invoked), scanned B, original, Apache-2.0.

A read-only checker for Helm charts, which are packages of templates used to create Kubernetes configuration. It examines chart metadata, templates, values, custom resources, schemas, rendered YAML, and security practices.

In plain words
What is it for?
Use it to lint charts, troubleshoot rendering failures, check Kubernetes schemas and CRDs, and review charts before deployment.
Why use it?
It finds problems that may only appear when Helm turns templates into Kubernetes files. It provides proposed improvements before a chart is released or deployed.

    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
    Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

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 B, and why

helm-validator scanned grade B with 2 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 2mo ago.

The scan reads SKILL.md. This mod also ships 7 executable files (scripts/detect_crd_wrapper.sh, scripts/detect_crd.py, scripts/generate_helpers.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.

Recursive force deletemediumDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

rm -rf temp-chart

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Helm Chart Validator & Analysis Toolkit

Overview

This skill provides a comprehensive validation and analysis workflow for Helm charts, combining Helm-native linting, template rendering, YAML validation, schema validation, CRD documentation lookup, and security best practices checking.

IMPORTANT: This validator is read-only by default. It analyzes charts and proposes improvements. Only modify files when the user explicitly asks to apply fixes.

Trigger Cases

Use this skill when one or more of these top cases apply:

  • The user asks to validate, lint, check, test, or troubleshoot a Helm chart
  • Helm templates fail to render, lint, or produce valid Kubernetes YAML
  • A pre-deployment quality gate is needed (schema, dry-run, security checks)
  • CRD resources are present and their spec fields must be verified against docs
  • The user wants a severity-based validation report with proposed remediations

Trigger phrase examples:

  • "Validate this Helm chart before release"
  • "Why does helm template fail?"
  • "Check this chart for Kubernetes and security issues"

Out of scope by default:

  • New chart scaffolding or broad chart generation (use helm-generator)

Role Boundaries

  • This skill validates and reports; it does not silently rewrite user files.
  • It can propose concrete patches and apply them only when the user explicitly requests fixes.
  • If execution constraints block a stage, it must continue with reachable stages and document the skip reason.

Execution Model

  1. Run stages in order (1 through 10).
  2. Keep going after stage-level failures to collect complete findings, unless rendering fails and no manifests exist.
  3. If Stage 4 produces no manifests, mark Stages 5 to 9 as blocked and continue to Stage 10 reporting.
  4. Treat Stage 8 as environment-dependent optional; treat Stage 9 and Stage 10 as mandatory when manifests exist.
  5. For every skipped stage, record the exact tool/environment reason in the final summary table.

Changes

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.
