CLAUDE.md

charts CLAUDE.md is an instructions file for Claude Code from duyet/charts. It costs 3,153 tokens per session, scanned A, original, MIT.

Project guidance for developing duyet/charts, a repository of Helm charts used to configure software deployments on Kubernetes.

In plain words
What is it for?
Use it when contributing to the repository or deciding how its Helm charts should be structured and documented.
Why use it?
It establishes shared principles for sensible defaults, configurable production settings, and consistent chart design.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions CLAUDE.md.

This is duyet/charts's own configuration. It tells Claude Code how to work on charts itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything charts configures →

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

charts CLAUDE.md 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 2mo ago.

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.

CLAUDE.md - Project Philosophy & Development Guide

"Simplicity is the ultimate sophistication." - Leonardo da Vinci

This document captures the soul of this Helm charts repository. Read this first before contributing.

The Vision

This repository is a collection of production-ready Helm charts that guide users toward secure, scalable deployments while maintaining the flexibility to customize for their needs.

We don't just make charts that work—we make charts that are inevitable. Every configuration option should feel natural. Every default should be sensible. Every template should be elegant.

Core Principles

1. Simplicity Without Losing Power

The best solutions are simple but not simplistic. Our charts should:

  • Provide sensible defaults that work out of the box
  • Expose configuration for production requirements
  • Hide complexity without limiting capability
  • Make the common case easy and the advanced case possible

Example: Default to 1 replica for simplicity, but always make replicaCount configurable for production scaling.

2. Consistency is Kindness

When users move between charts in this repository, they should feel at home. This means:

  • Uniform values.yaml structure across all charts
  • Consistent naming conventions
  • Shared patterns for common features (service accounts, security contexts, etc.)
  • Modern, standardized template syntax (nindent, not indent | trim)

Why it matters: Cognitive load is a user experience issue. Consistency reduces friction.

3. Security by Default

Security isn't optional. Every chart should:

  • Use non-root users by default where possible
  • Support (and encourage) security contexts
  • Never hard-code secrets
  • Always support existingSecret patterns
  • Provide resource limits as defaults

Philosophy: Make the secure path the easy path.

4. Production-Ready from Day One

These charts aren't experiments. They're tools for running real workloads. This means:

  • Config changes trigger automatic pod restarts (via checksum annotations)
  • Health checks are included and sensible
  • Resource limits prevent runaway processes
  • Support for PodDisruptionBudgets on critical services
  • Clear NOTES.txt with post-installation guidance

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.
