helm-chart-expert

helm-chart-expert is a skill for Claude Code from atretyak1985/swarmery. It costs 78 tokens per session (3,588 once invoked), scanned A, original, Apache-2.0.

A guide for writing and checking Helm charts, which are templates that generate Kubernetes configuration. It covers chart structure, settings files, dependencies, and validation.

In plain words
What is it for?
Use it to create or modify chart templates, organise values files, manage subcharts, render charts, run lint checks, perform dry runs, and update chart versions.
Why use it?
It helps prevent template errors, missing settings, incorrect labels, and dependency problems before charts are deployed to a cluster.

Skill for Claude Code

Written for Claude Code: shipped in a Claude Code plugin. Also seen: reads .claude/ paths.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is bash scripts/check-chart-sync.sh.

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

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

helm-chart-expert 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 7d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/validate-chart.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.

How it starts

The opening of the file, as written. The whole thing — 295 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Purpose

Author and validate Helm charts for the project's infrastructure and chart repos (project.json → repos). This skill covers chart structure, Go template patterns, values management, subchart dependencies, and validation workflows (lint, template render, dry-run). It does not cover end-to-end deploy orchestration (use deployment), Keycloak realm/client configuration (use keycloak), IaC drift detection (use infrastructure-as-code), or Docker image builds (use docker-build).

When to use this skill (triggers)

  • Creating or modifying Helm chart templates (deployment, service, ingress, networkpolicy, etc.)
  • Structuring or reviewing values.yaml / values.<env>.yaml files
  • Managing subchart dependencies in Chart.yaml and Chart.lock
  • Running chart validation: helm lint, helm template, helm upgrade --dry-run
  • Debugging template rendering errors (nil pointer, label mismatch, values not applied)
  • Bumping chart versions and synchronizing umbrella/subchart versions
  • Reviewing Helm template correctness with file:line citations

When NOT to use this skill (anti-triggers)

  • End-to-end deploy orchestration (helm upgrade to a live cluster) -- use deployment
  • Keycloak realm setup, client config, or Auth.js integration -- use keycloak
  • Terraform drift detection or post-incident IaC capture -- use infrastructure-as-code
  • Docker image builds or multi-arch buildx -- use docker-build
  • Migration safety checks or schema alignment -- use migration-check
  • GCP firewall rules or VM-level k8s debugging -- use kubernetes-deployment
  • CI/CD pipeline YAML review -- use gitlab-ci-cd

Required environment (Runtime: .claude/skills/helm-chart-expert/SKILL.md)

  • Tools/libraries: helm (v3.10+), kubectl (v1.28+), bash
  • Repos: the project's infrastructure and chart repos (project.json → repos)
  • Validation script: .claude/skills/helm-chart-expert/scripts/validate-chart.sh

Inputs

  • chart_path: string -- path to the chart directory (e.g., <infra-repo>/)
  • values_file: string (optional) -- path to the values file to validate against
  • operation: enum -- one of: author, validate, review, debug

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
