cloud-sql-postgres-lifecycle

A set of tools for managing PostgreSQL databases on Google Cloud SQL, Google's managed database service, throughout their lifecycle. It covers backups, restores, version upgrade checks, and instance status.

In plain words
What is it for?
Use it to create or restore backups, review database versions and replication status, check uptime and instance health, and assess compatibility before a major version upgrade.
Why use it?
It helps protect data, assess whether a major database upgrade is safe, and understand the current state of a database instance. It also supports checking long-running operations.

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

cloud-sql-postgres-lifecycle 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 yesterday.

The scan reads SKILL.md. This mod also ships 7 executable files (scripts/create_backup.js, scripts/database_overview.js, scripts/get_instance.js, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 122 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Usage

All scripts can be executed using Node.js. Replace <param_name> and <param_value> with actual values.

Bash: node <skill_dir>/scripts/<script_name>.js '{"<param_name>": "<param_value>"}'

PowerShell: node <skill_dir>/scripts/<script_name>.js '{\"<param_name>\": \"<param_value>\"}'

Note: The scripts automatically load the environment variables from various .env files. Do not ask the user to set vars unless skill executions fails due to env var absence.

Scripts

create_backup

Creates a backup on a Cloud SQL instance.

Parameters
Name Type Description Required Default
project string The GCP project ID. This is pre-configured; do not ask for it unless the user explicitly provides a different one. No
instance string Cloud SQL instance ID. This does not include the project ID. Yes
location string Location of the backup run. No
backup_description string The description of this backup run. No

database_overview

Fetches the current state of the PostgreSQL server, returning the version, whether it's a replica, uptime duration, maximum connection limit, number of current connections, number of active connections, and the percentage of connections in use.


get_instance

Parameters
Name Type Description Required Default
projectId string The GCP project ID. This is pre-configured; do not ask for it unless the user explicitly provides a different one. No
instanceId string The instance ID Yes

list_instances

Lists all type of Cloud SQL instances for a project.

Parameters
Name Type Description Required Default
project string The GCP project ID. This is pre-configured; do not ask for it unless the user explicitly provides a different one. No

Files

What ships with it

7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

cloud-sql-postgres-lifecycle is a skill published in the GitHub repository gemini-cli-extensions/cloud-sql-postgresql (42 stars, last pushed 4d ago), licensed Apache-2.0. It adds 40 tokens to every session and 1,077 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
