What it does

Helm Chart Builder is an agent skill from borghei/Claude-Skills. This skill should be used when the user asks to "analyze Helm charts", "validate Helm values", "review chart structure", "check Kubernetes Helm templates", or "audit chart dependencies and configuration".

Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files, including scripts and reference files (for example `examples/Chart.yaml`, `examples/values.yaml` and `references/helm-best-practices.md`).

It sits in DevOps & Cloud, covering Container orchestration. It works with Helm and Kubernetes. The repository describes itself as: 385 AI skills, 77 expert agents, and 900 stdlib Python tools for every team: engineering, PM, marketing, C-level, compliance, business ops, research, and a LinkedIn toolkit… The licence is MIT.

When your agent uses it

Asks to analyze Helm charts
Validate Helm values
Review chart structure
Check Kubernetes Helm templates

Example prompts

“analyze Helm charts”
“validate Helm values”
“review chart structure”
“/helm-chart-builder”

Requirements

Python 3

Workflow steps

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

Analyze structure - Run chart_analyzer.py to check chart organization
Validate defaults - Run values_validator.py against default values.yaml
Check environments - Validate each environment's values file
Review findings - Address critical issues first, then warnings
Re-check - Confirm fixes pass validation

What it can do on your machine

Read from SKILL.md and the folder at commit c9a1487. 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
Ships 2 files in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
- python
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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

Helm Chart Builder loads about 1.4k tokens when it runs, and up to ~2.1k if it reads all its reference files. Until then it costs about 56 tokens; SKILL.md has 456 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~56
When it runs · the whole SKILL.md, loaded when a task matches: ~1.4k
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~2.1k

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

Auto-check passed

The automated check found no risky patterns in SKILL.md.

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); the scripts in this folder are not scanned.

Helm Chart Builder

Category: Engineering Domain: Kubernetes & Helm

Overview

The Helm Chart Builder skill provides automated analysis of Helm charts including structure validation, values checking, template inspection, and dependency review. It helps teams maintain high-quality charts with correct configurations, proper security contexts, and complete documentation.

Clarify First

Before analyzing the chart, confirm these inputs. If any is unknown or vague, ASK — do not assume:

Chart path — which chart directory to analyze (sets --path/--chart)
Values files — which environment values files to validate (sets --values and what gets checked against best practices)
Strictness — strict/lint mode and JSON for CI (sets --strict --format json and whether findings gate the pipeline)

Stop rule: ask only the 2-3 that most change the output. If the user says "just draft it," proceed and list your assumptions at the top of the artifact.

Quick Start

bash

# Analyze chart structure and quality
python scripts/chart_analyzer.py --path ./charts/my-app

# Validate values.yaml against chart requirements
python scripts/values_validator.py --chart ./charts/my-app --values values-prod.yaml

# JSON output for CI
python scripts/chart_analyzer.py --path ./charts/my-app --format json

# Validate multiple values files
python scripts/values_validator.py --chart ./charts/my-app --values values-dev.yaml values-prod.yaml

Tools Overview

chart_analyzer.py

Analyzes Helm chart structure, metadata, templates, and dependencies.

Feature	Description
Structure validation	Checks required files exist (Chart.yaml, values.yaml, templates/)
Metadata check	Validates Chart.yaml fields, version format, appVersion
Template review	Inspects templates for common patterns and issues
Dependency analysis	Reviews subchart dependencies and version constraints
Documentation check	Verifies NOTES.txt and README presence

values_validator.py

Validates values files against chart expectations and Kubernetes best practices.

Feature	Description
Resource limits	Checks for CPU/memory requests and limits
Security context	Validates runAsNonRoot, readOnlyRootFilesystem
Replica count	Checks for production-appropriate replica counts
Image tags	Flags use of latest or missing image tags
Ingress config	Validates ingress annotations and TLS settings

Workflows

Chart Review Workflow

Analyze structure - Run chart_analyzer.py to check chart organization
Validate defaults - Run values_validator.py against default values.yaml
Check environments - Validate each environment's values file
Review findings - Address critical issues first, then warnings
Re-check - Confirm fixes pass validation

Show full SKILL.md (169 more words)Show less

Pre-Release Workflow

Bump version - Update Chart.yaml version and appVersion
Lint chart - Run chart_analyzer.py in strict mode
Validate all values - Check every environment's values file
Check dependencies - Ensure subchart versions are pinned
Package - Chart is ready for helm package

CI Integration

bash

# Structure check
python scripts/chart_analyzer.py --path ./charts/my-app --format json --strict

# Values validation for all environments
for env in dev staging production; do
  python scripts/values_validator.py \
    --chart ./charts/my-app \
    --values "values-${env}.yaml"
done

With the skills CLI, run `npx skills add borghei/Claude-Skills --skill helm-chart-builder -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/helm-chart-builder, .gemini/skills/helm-chart-builder, .github/skills/helm-chart-builder and .opencode/skills/helm-chart-builder in your project.

What does Helm Chart Builder need to run?

Going by SKILL.md and its folder, Helm Chart Builder needs Python for the scripts in its folder and the command-line tools its instructions call (python). Our summary lists: Python 3.

Does Helm Chart Builder access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Helm Chart Builder safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.

What licence does Helm Chart Builder use?

Helm Chart Builder is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Helm Chart Builder use?

About 1.4k tokens (SKILL.md is roughly 5.7k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 694 tokens, read only when the agent opens those files.
