database-scout

database-scout is a skill for Claude Code, Codex from serejaris/kimi-skills. It costs 76 tokens per session (1,174 once invoked), scanned A, a copy of database-scout, MIT.

A read-only explorer for SQLite and PostgreSQL databases. It lists tables, shows their columns and relationships, previews records, draws Mermaid ER diagrams, and runs safe queries without changing data.

In plain words
What is it for?
Use it to inspect schemas, constraints, indexes, and sample rows; map table relationships; and run SELECT-style queries.
Why use it?
It helps developers understand an unfamiliar database while reducing the risk of accidental edits during investigation.

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

database-scout 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 7d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/db_explorer.py), 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.

database-scout

Read-only exploration tool for SQLite / PostgreSQL databases — inspect table schemas, preview data, generate ER diagrams, and run safe queries.

Feature Overview

Feature Description
List all tables Show tables and views in the database, with row counts
Inspect table schema Column names, types, constraints (PK/FK/NOT NULL), indexes, defaults
Data preview View the first N rows of a table
ER diagram generation Output Mermaid erDiagram syntax, ready to render
Safe read-only queries Only SELECT/WITH/EXPLAIN allowed; write operations are blocked

Security Mechanisms

  • Connection-level read-only: SQLite opens with ?mode=ro URI; PostgreSQL uses SET SESSION READ ONLY
  • SQL whitelist: Only statements starting with SELECT / WITH / EXPLAIN / PRAGMA / SHOW are allowed
  • Dangerous keyword blocking: INSERT, UPDATE, DELETE, DROP, ALTER, CREATE, and 30+ other keywords are blocked
  • Multi-statement blocking: Semicolon-separated multiple SQL statements are rejected (prevents injection)
  • Identifier escaping: Table names are double-quote escaped to prevent SQL injection

Quick Start

# List all tables in a SQLite database
python3 scripts/db_explorer.py --db-path data.db list-tables

# Inspect table schema
python3 scripts/db_explorer.py --db-path data.db describe users

# Preview data (default 20 rows)
python3 scripts/db_explorer.py --db-path data.db preview orders --limit 10

# Generate Mermaid ER diagram
python3 scripts/db_explorer.py --db-path data.db er-diagram

# Run a read-only query
python3 scripts/db_explorer.py --db-path data.db query "SELECT name, age FROM users WHERE age > 18 LIMIT 10"

PostgreSQL

# Connect to PostgreSQL
python3 scripts/db_explorer.py --db-type postgres --dsn "host=localhost dbname=mydb user=reader" list-tables

# Inspect table schema
python3 scripts/db_explorer.py --db-type postgres --dsn "host=localhost dbname=mydb user=reader" describe orders

What ships with it

2 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.
