managing-tls-certificates

managing-tls-certificates is a skill for Claude Code, Codex from cockroachdb/cursor-plugin. It costs 61 tokens per session (2,591 once invoked), scanned A, a copy of managing-tls-certificates, Apache-2.0.

A guide to configuring and maintaining TLS certificates for CockroachDB clusters. TLS encrypts connections, while mutual TLS can also require clients to prove their identity with certificates.

In plain words
What is it for?
Use it to configure client-certificate authentication, manage certificate authorities, rotate certificates, troubleshoot SSL/TLS errors, and set up certificate-based access for changefeeds to Kafka.
Why use it?
It helps diagnose encrypted-connection failures and reduces the risk of expired, missing, or incorrectly configured certificates when applications connect to CockroachDB.

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

managing-tls-certificates 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 4d 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.

Managing TLS Certificates

Manages TLS certificates for CockroachDB clusters, covering CA certificate downloads, client certificate authentication setup, certificate rotation, and troubleshooting common SSL/TLS connection errors. Addresses both CockroachDB Cloud (always-on TLS) and self-hosted certificate lifecycle management.

When to Use This Skill

  • Troubleshooting SSL/TLS connection errors from application clients (DBeaver, TypeORM, psql, Go, Python, Java)
  • Setting up client certificate authentication on CockroachDB Cloud
  • Uploading a custom Client CA to a Cloud cluster
  • Rotating or renewing certificates (Cloud or self-hosted)
  • Configuring mTLS for CDC changefeeds to Kafka
  • Downloading or locating the CA certificate for a Cloud cluster

Prerequisites

CockroachDB Cloud:

  • ccloud CLI authenticated (ccloud auth login)
  • Cloud Console access for CA certificate download
  • Cluster Admin role for client CA configuration

Self-hosted:

  • cockroach cert CLI available
  • Admin access to cluster nodes
  • OpenSSL for certificate inspection and generation

Verify access:

# Cloud
ccloud auth whoami
ccloud cluster list

# Self-hosted — check existing certificates
cockroach cert list --certs-dir=<certs-directory>

Configuration Decisions

Before proceeding, determine the user's deployment model. Ask which option applies, then follow only the relevant sections below.

Decision 1 — Deployment model:

  • CockroachDB Cloud: TLS is always on and the cluster CA is managed by Cockroach Labs. Follow Part 1 for CA download, client certificate auth, and Cloud certificate rotation.
  • Self-hosted: Full manual certificate lifecycle management (CA, node, and client certificates). Follow Part 2 for certificate creation, rotation, and management.

Parts 3 (Troubleshooting) and 4 (mTLS for CDC) apply to both deployment models.

Steps

Part 1: CockroachDB Cloud TLS

Follow this part if the user selected CockroachDB Cloud in Decision 1.

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.
