A read-only command-line tool for inspecting PostgreSQL, MySQL, and SQLite databases. It can provide schema details, sample records, query results, and checks against the actual database structure.

Use it to inspect tables and schemas, run safe read-only queries, view sample data, or check whether code matches the database.

It lets you verify database facts without changing data. This reduces guesswork when writing code or investigating how tables and fields are really organized.

Per session 158 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.

Origin unknown No closer match found in the catalogue.

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	$0.00158	$0.01563
Opus 5.5	$0.00063	$0.00625
Sonnet 5.5	$0.00032	$0.00313
Haiku 4.5	$0.00016	$0.00156

Measured 10d ago against content hash da1ba1c5d4ad, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

db-explorer 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 10d 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.

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.
