sql-cli

A guide for running MySQL and PostgreSQL database queries from the command line using mycli and native database tools. MySQL and PostgreSQL are systems that store and query structured data.

In plain words
What is it for?
Use it to connect to MySQL or PostgreSQL, run queries, inspect tables, and perform database operations from Windows, macOS, or Linux.
Why use it?
It provides a direct way to inspect and change databases from a terminal, with less conversational overhead than using application debugging tools.

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

sql-cli 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 1 executable file (sql-cli.sh), 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.

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.

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.

sql-cli is a skill published in the GitHub repository Interstellar-code/claud-skills (17 stars, last pushed 7mo ago), with no licence file. It adds 40 tokens to every session and 2,761 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings.
