# Cloud SQL Basics

Cloud SQL is a fully managed relational database service for MySQL, PostgreSQL,
and SQL Server. It automates time-consuming tasks like patches, updates,
backups, and replicas, while providing high performance and availability for
your applications.

## Prerequisites

Ensure you have the necessary IAM permissions to create and manage Cloud SQL
instances. The **Cloud SQL Admin** (`roles/cloudsql.admin`) role provides full
access to Cloud SQL resources.

## Quick Start (PostgreSQL)

1.  **Enable the API:**
    ```bash
    gcloud services enable sqladmin.googleapis.com --quiet
    ```

2.  **Create an Instance:**
    ```bash
    gcloud sql instances create INSTANCE_NAME \
      --database-version=POSTGRES_18 \
      --cpu=2 \
      --memory=7680MiB \
      --region=REGION \
      --quiet
    ```

3.  **Set a password for the default user:**

    Because this is a Cloud SQL for PostgreSQL instance, the default admin user
    is `postgres`:
    ```bash
    gcloud sql users set-password postgres \
      --instance=INSTANCE_NAME --password=PASSWORD \
      --quiet
    ```

4.  **Create a database:**
    ```bash
    gcloud sql databases create DATABASE_NAME \
      --instance=INSTANCE_NAME \
      --quiet
    ```

5.  **Get the instance connection name:**

    You need the instance connection name (which is formatted as
    `PROJECT_ID:REGION:INSTANCE_NAME`) to connect using the Cloud SQL Auth
    Proxy. Retrieve it with the following command:
    ```bash
    gcloud sql instances describe INSTANCE_NAME \
      --format="value(connectionName)" \
      --quiet
    ```

6.  **Connect to the instance:**

    The Cloud SQL Auth Proxy must be running to be able to connect to the
    instance. In a separate terminal, start the proxy using the connection name:
    ```bash
    ./cloud-sql-proxy INSTANCE_CONNECTION_NAME
    ```

    With the proxy running, connect using `psql` in another terminal:
    ```bash
    psql "host=127.0.0.1 port=5432 user=postgres dbname=DATABASE_NAME password=PASSWORD sslmode=disable"
    ```

cupynumeric-migration-readiness

Included

Pre-migration readiness assessor for porting NumPy to cuPyNumeric. Use BEFORE substantial porting work begins when the user asks whether code will scale on GPU, whether they should migrate to cuPyNumeric, which NumPy patterns transfer cleanly, what must be refactored before porting, or mentions pre-port assessment, scaling analysis, or refactor planning. Inspect the user's source code, look up NumPy usage, cross-reference the cuPyNumeric API support manifest, and distinguish distributed-scaling-friendly patterns from blockers such as unsupported APIs, scalar synchronization, host round-trips, Python/object-heavy control flow, shape/data-dependent branching, and in-place mutation hazards. Produce a verdict of READY, LIGHT REFACTOR, SIGNIFICANT REFACTOR, or NOT RECOMMENDED, with concrete refactor pointers.

alibabacloud-data-agent-skill

Included

Invoke Alibaba Cloud Apsara Data Agent for Analytics via CLI to perform natural language-driven data analysis on enterprise databases. Data Agent for Analytics is an intelligent data analysis agent developed by Alibaba Cloud Database team for enterprise users. It automatically completes requirement analysis, data understanding, analysis insights, and report generation based on natural language descriptions. This tool supports: discovering data resources (instances/databases/tables) managed in DMS, initiating query or deep analysis sessions, real-time progress tracking, and retrieving analysis conclusions and generated reports. Use this Skill when users need to query databases, analyze data trends, generate data reports, ask questions in natural language, or mention "Data Agent", "data analysis", "database query", "SQL analysis", "data insights".

token-optimizer

Included

Reduce OpenClaw token usage and API costs through smart model routing, heartbeat optimization, budget tracking, and native 2026.2.15 features (session pruning, bootstrap size limits, cache TTL alignment). Use when token costs are high, API rate limits are being hit, or hosting multiple agents at scale. The 4 executable scripts (context_optimizer, model_router, heartbeat_optimizer, token_tracker) are local-only — no network requests, no subprocess calls, no system modifications. Reference files (PROVIDERS.md, config-patches.json) document optional multi-provider strategies that require external API keys and network access if you choose to use them. See SECURITY.md for full breakdown.
