What is openshell-k8s-operator CLAUDE.md?

Project instructions for a Kubernetes operator that turns custom Kubernetes resources into calls to an OpenShell gateway and mirrors gateway state back into resource status. Kubernetes operators automate management of applications or services inside Kubernetes.

Use them when working on resource reconcilers, provider credentials, policies, sandboxes, workspaces, provider profiles, cleanup, and gateway synchronization.

They clarify that the operator is a thin translator rather than a replacement for the gateway, helping agents preserve the intended division of responsibility.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00828	$0.00828
Opus 5.5	$0.00331	$0.00331

Security

Grade A, and why

openshell-k8s-operator 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.

What this is

A Kubernetes operator providing declarative CRDs over an OpenShell gateway's gRPC control plane. It is a thin front-end: it translates custom resources into gateway API calls and mirrors gateway state back into .status. It does not reimplement the gateway.

Status: OpenShellSandbox (create/get/delete), Provider (static credentials from a Secret, entitlement-checked, synced with a rotation watch), Policy (a reusable policy document validated by the gateway parser and applied to a sandbox at creation via policyRef), OpenShellWorkspace (a cluster-scoped gateway tenancy boundary with declarative membership, joined by sandboxes and providers via spec.workspace), and OpenShellProviderProfile (a cluster-scoped, platform-scoped provider type definition — spine-typed with opaque arrays validated by the gateway's openshell-providers parser, imported and updated in place) reconcilers. Sandbox, Provider, Workspace, and ProviderProfile use finalizer-based cleanup; Policy owns no gateway state, so it has none. Workspace-scoped provider profiles, and Providers v2 (gateway-managed OAuth2 refresh), are deferred.

The repo is a Cargo workspace with two crates: crates/operator (the operator) and crates/issuer (a small static OIDC issuer — mint + serve subcommands — that the Helm chart bundles to mint the operator's gateway bearer). The operator authenticates to the gateway with an OIDC bearer, runs lease-based leader election, and serves /healthz + /readyz probes.

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.
