What is scylladb-cloud-setup?

A step-by-step guide for connecting an application to a ScyllaDB Cloud database cluster, including choosing a CQL driver and setting up login details.

Connecting applications to ScyllaDB Cloud, configuring authentication, selecting drivers, and troubleshooting connection problems.

It helps avoid connection errors caused by the wrong driver, version, credentials, or cluster settings.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add scylladb/agent-skills --skill scylladb-cloud-setup

Clone the repo

git clone --depth 1 https://github.com/scylladb/agent-skills

Made for: Claude Code.

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	$0.00182	$0.02514
Opus 5.5	$0.00073	$0.01006
Sonnet 5.5	$0.00036	$0.00503
Haiku 4.5	$0.00018	$0.00251

Security

Grade A, and why

scylladb-cloud-setup 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 20d 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.

ScyllaDB Cloud Connection Setup

If the task goes beyond this skill, use the parent scylladb skill for a ScyllaDB overview and the list of other ScyllaDB skills. If it is not installed, fetch it from https://raw.githubusercontent.com/scylladb/agent-skills/main/skills/scylladb/SKILL.md.

This skill guides users through connecting their application to a ScyllaDB Cloud cluster using the appropriate CQL driver.

When to Use This Skill

The user needs to connect an application to a ScyllaDB Cloud cluster for the first time
The user asks which CQL driver to use for their language, or which driver version
The user is configuring credentials, contact points, DC-aware load balancing, or the default consistency level
The user asks why the driver opens so many connections, or wants to change the pool size
A connection to ScyllaDB Cloud fails or times out
The user is setting up IP allowlisting or VPC peering

For adjacent topics, use the sibling skill instead:

Schema and table design after the connection works: scylladb-data-modeling
Vector columns, vector indexes, and driver versions with vector type support: scylladb-vector-search
Managing ScyllaDB Cloud clusters from an AI agent: scylladb-cloud-mcp
Self-managed clusters on Kubernetes: scylladb-kubernetes
DynamoDB SDK clients instead of CQL drivers: scylladb-alternator

Overview

Connecting to ScyllaDB Cloud requires:

Cluster credentials — username, password, and node addresses from the ScyllaDB Cloud Console
A ScyllaDB CQL driver — installed for the user's programming language

This is an interactive step-by-step guide. The agent detects the user's environment and provides tailored instructions.

Step 1: Verify the Cluster is Running

Ask the user to confirm they have a ScyllaDB Cloud cluster. If not, direct them to:

Go to cloud.scylladb.com and log in (or sign up)
Click New Cluster or Free Trial
Choose AWS or GCP, configure region, instance type, and cluster name
Whitelist their IP address
(Recommended) Enable VPC Peering during cluster creation — it cannot be enabled later
Click Launch Cluster and wait for provisioning

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.
