Automated summary

Scaffolds a new Helm chart with standard templates and project conventions under deploy/charts/.

Strengths

  • Follows project conventions via .claude/rules/helm-charts.md
  • Generates all essential templates (deployment, service, configmap, ingress, HPA)
  • Includes sensible defaults for resources and health checks
  • Validates the chart with helm lint and template commands

Limitations

  • Assumes a specific directory structure (deploy/charts/) and namespace (signalbeam)
  • Does not handle advanced Helm features like subcharts or dependencies
  • Uses static templates that may need customization for non-standard services
When to use it

Use when adding a new microservice to the Signalbeam platform and you need a standardized Kubernetes chart.

When not to use it

Do not use when creating a chart for a service outside the Signalbeam ecosystem or when you need a highly customized chart structure.

Security analysis

Safe
Quality score88/100

The skill only uses safe commands (helm lint, helm template) and writes to a designated directory. No risky operations, no execution of arbitrary code, no exfiltration.

No concerns found

Add Helm Chart

Scaffold a new Helm chart following project conventions.

Arguments

  • {chart-name} — Name of the chart (required, e.g., signalbeam-platform, device-manager)

Process

  1. Create the chart directory structure under deploy/charts/{chart-name}/:
deploy/charts/{chart-name}/
├── Chart.yaml
├── values.yaml
├── templates/
│   ├── _helpers.tpl
│   ├── deployment.yaml
│   ├── service.yaml
│   ├── configmap.yaml
│   ├── ingress.yaml
│   └── hpa.yaml

  1. Read .claude/rules/helm-charts.md for project conventions.

  2. Generate files following these conventions:

    • Namespace: signalbeam
    • Standard Kubernetes labels: app.kubernetes.io/name, app.kubernetes.io/instance, app.kubernetes.io/version
    • Health check paths: /health/live (liveness), /health/ready (readiness)
    • Resource limits and requests with sensible defaults
    • HPA with min 1, max 3 replicas

  3. Chart.yaml template:

apiVersion: v2
name: {chart-name}
description: {description}
type: application
version: 0.1.0
appVersion: "0.1.0"

  1. values.yaml — Include configurable values for:

    • image.repository, image.tag, image.pullPolicy
    • replicaCount
    • resources.requests and resources.limits
    • service.type, service.port
    • ingress.enabled, ingress.hosts
    • env (environment variables as key-value map)

  2. Validate the chart:

helm lint deploy/charts/{chart-name}
helm template test deploy/charts/{chart-name} > /dev/null

After Scaffolding

Report what was created and remind to:

  • Customize values.yaml for the specific service
  • Add environment-specific value overrides if needed
  • Update any umbrella chart dependencies if applicable

From the file to a first result

The download contains exactly the content displayed on this page. This copy may differ from the latest version in the source repository.

View the source and supporting files

This download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.

1. Download the file

Download SKILL.md

From the root of a test project, save the file as .skill-downloads/add-helm-chart-mm8o522b/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.

Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.

mkdir -p '.skill-downloads/add-helm-chart-mm8o522b' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/add-helm-chart-mm8o522b/download' --output '.skill-downloads/add-helm-chart-mm8o522b/SKILL.md.part' && mv '.skill-downloads/add-helm-chart-mm8o522b/SKILL.md.part' '.skill-downloads/add-helm-chart-mm8o522b/SKILL.md'

2. Check prerequisites

Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.

Tools declared by the author (check availability in your agent): Bash, Write, Read, Glob

No recognized prerequisites section in this file. This does not mean it is self-contained: libraries, tools and access requirements may be mentioned elsewhere in the content or source repository.

The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.

3. Load the skill

After inspection, copy the complete folder into your project using one of the commands below, then open a new tool session. The command stops if a folder with the same name already exists: compare the files before replacing it.

Claude Code
test -f '.skill-downloads/add-helm-chart-mm8o522b/SKILL.md' && test -s '.skill-downloads/add-helm-chart-mm8o522b/SKILL.md' && mkdir -p '.claude/skills' && test ! -e '.claude/skills/add-helm-chart' && cp -R '.skill-downloads/add-helm-chart-mm8o522b' '.claude/skills/add-helm-chart'

OpenSkills

OpenSkills must already be installed. The local install/read procedure is checked with OpenSkills 1.5.0, which requires Node.js ≥ 20.6.0. Catalog slugs are not resolved automatically.

Official OpenSkills installation
openskills install './.skill-downloads/add-helm-chart-mm8o522b'

openskills read 'add-helm-chart-mm8o522b'

Reading should display the installed file content and its base directory. It does not run the skill or install its dependencies.

For an agent that reads AGENTS.md, then sync the index. This command changes AGENTS.md: review the diff before using it.

openskills sync

Manual method or another tool: attach SKILL.md to a conversation, or open it in an agent that can read files. Include any required supporting resources. No universal folder is recognized by every tool.

4. Try a first task

Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:

Read .skill-downloads/add-helm-chart-mm8o522b/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.

Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.
