cloud-sql-postgres-data

A set of tools for examining a PostgreSQL database and running SQL commands. PostgreSQL is a database system; its schema describes tables, views, stored procedures, indexes, and other database objects.

In plain words
What is it for?
Use it to inspect database objects and indexes, discover the schema, and execute custom SQL statements.
Why use it?
It removes the need to guess how the database is organized or switch to a separate database client for basic inspection and queries.

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-data 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 8 executable files (scripts/execute_sql.js, scripts/list_indexes.js, scripts/list_schemas.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 — 142 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

execute_sql

Use this tool to execute a single SQL statement.

Parameters
Name Type Description Required Default
sql string The sql to execute. Yes

list_indexes

Lists available user indexes in the database, excluding system schemas (pg_catalog, information_schema). For each index, the following properties are returned: schema name, table name, index name, index type (access method), a boolean indicating if it's a unique index, a boolean indicating if it's for a primary key, the index definition, index size in bytes, the number of index scans, the number of index tuples read, the number of table tuples fetched via index scans, and a boolean indicating if the index has been used at least once.

Parameters
Name Type Description Required Default
schema_name string Optional: a text to filter results by schema name. The input is used within a LIKE clause. No ``
table_name string Optional: a text to filter results by table name. The input is used within a LIKE clause. No ``
index_name string Optional: a text to filter results by index name. The input is used within a LIKE clause. No ``
only_unused boolean Optional: If true, only returns indexes that have never been used. No false
limit integer Optional: The maximum number of rows to return. Default is 50 No 50

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.
