CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Working on issues — mandatory workflow

The main Claude session acts as the task manager and does not implement issues itself:

1. Plan first, get approval: The manager presents a plan for the issue and waits for the user's explicit approval. No implementation before approval.
2. Delegate implementation: After approval, the manager launches a dedicated development agent. The agent implements the issue completely on its own branch and opens a PR.
3. PR comment handling by the agent: After opening the PR, the development agent watches it for review comments. New comments are addressed automatically (code changes, reply on the thread), and addressed threads are marked as resolved.
4. Agent lifetime: The development agent terminates itself once its PR has been merged (or closed).
5. Only after the PR has been merged by the user may work on the next issue begin. The user merges; never merge yourself.
6. After the merge, verify the linked issue was closed (auto-close via "Fixes #n"); close it manually if not.

Additional rules for all commits, PRs, issues, and comments:

• Do not add a Co-Authored-By trailer and do not append "Generated with Claude Code" footers.

What this repo is

A collection of self-made Helm charts, one directory per chart, published to a private OCI registry via GitHub Actions. There is no build system or test suite — validation is done with Helm itself:

helm lint <chart-name>
helm template <chart-name> --set ingress.domain=example.com --set ingress.clusterIssuer=letsencrypt   # render locally; required values vary per chart

Creating a new chart

Copy template-chart/ and replace every xxx placeholder — in file names (templates/xxx.deployment.yaml → templates/<app>.deployment.yaml), in Chart.yaml, and in the values.yaml keys and their .Values.xxx.* references inside templates. Then wire up CI:

1. Add .github/workflows/publish-<chart-name>.yml (copy an existing one, e.g. publish-outline.yml) — it triggers on pushes to <chart-name>/** and calls the reusable publish-helm-chart.yml.
2. Add the chart name to the chart-name choice list in .github/workflows/change-app-version.yml.

Versioning scheme

Chart.yaml versions follow version: <chart-semver>+up<appVersion> (e.g. 1.4.0+up1.9.2), with appVersion matching the suffix (dashes in the app version are normalized to dots in the suffix). When changing a chart's templates or values, bump the semver part; when only updating the app version, the change-app-version.yml workflow does it (it commits directly to main). Any push touching a chart directory publishes that chart, so the version must be bumped in the same change.

Chart conventions (from template-chart)

• All resources are named {{ .Release.Name }}-{{ .Chart.Name }}-<kind> (e.g. ...-deployment, ...-service, ...-secret).
• Image tags come from {{ .Chart.AppVersion }}.
• Secrets are 1Password OnePasswordItem CRs: values expose secrets.<name>SecretRef holding an op:// item path; the operator materializes the Kubernetes Secret.
• Ingress assumes ingressClassName: nginx and cert-manager: ingress.clusterIssuer and ingress.domain are required values, TLS secret named tls-<release>-<chart>-ingress.
• env entries in values support Helm templating — the deployment renders them through tpl, and supports value, secretKeyRef, and configMapKeyRef forms.
• Hardened defaults: automountServiceAccountToken: false, non-root user, readOnlyRootFilesystem: true, all capabilities dropped; probes and resource requests/limits always set.
• Stateful apps use a StatefulSet in a <app>.sfs.yaml template instead of a deployment.
• No chart has dependencies; charts/ directories are empty.
