mysql-query

mysql-query is a skill for Claude Code, Codex from AllenMuu/mysql-cli. It costs 81 tokens per session (1,431 once invoked), scanned A, original, MIT.

A skill for running SQL commands against MySQL databases through the mysql-cli command-line tool. SQL is the language used to read and change structured database data.

In plain words
What is it for?
Selecting and inspecting data, inserting, updating, or deleting rows, creating or changing database structures, and running several changes as one transaction.
Why use it?
It provides a defined process for queries, database changes, table creation or alteration, and multi-step transactions, with read-only output by default.

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

mysql-query 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 3d 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.

mysql-query Skill

CRITICAL - Before starting, you MUST Read ../mysql-shared/SKILL.md. It contains config and datasource, global flags, safety model, exit codes, error recovery, and output formats.

Convention: assume mysql-cli is on PATH.

This skill covers SQL execution: read-only queries, multi-statement transactions, and writes (DML/DDL). For schema exploration and data sampling, use the mysql-schema skill.


Trigger Conditions

Use this skill when the user asks about any of the following:

  • Database queries or running SQL (SELECT/INSERT/UPDATE/DELETE)
  • Multi-statement atomic transactions (txn)
  • DDL (CREATE/ALTER/DROP and other structural changes)

Commands

All commands share global flags (see mysql-shared): -d/--datasource, -f/--format (default json), --write, --ddl, --yes, --limit, --timeout, --config, and connection overrides.

Query

Command Description
mysql-cli query "<sql>" Run one SQL statement. Read by default; --write for DML, --write --ddl for DDL.
  • Read queries route through QueryContext and return rows.
  • DML/DDL route through a transactional write path and return rows_affected.
  • Do not send write SQL without --write; the driver rejects writes in the read path and you get exit 3.

Transaction

Command Description
mysql-cli txn "<sql1>" ["<sql2>"...] Run multiple statements in one atomic transaction.
  • Use this whenever you have more than one statement - query rejects multi-statement input (exit 7).
  • Needs --write (and --ddl/--yes as appropriate) for any write inside.

Write

Writes are gated by safety flags (see mysql-shared Security Model). Destructive ops additionally need --yes.

Human confirmation required: every write flag (--write/--ddl/--yes) triggers a Claude Code permission prompt. --yes marks the op as destructive -- it does not skip review. Add the flags the op needs; a human approves the actual execution.

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.

mysql-query is a skill published in the GitHub repository AllenMuu/mysql-cli (2 stars, last pushed 22d ago), licensed MIT. It adds 81 tokens to every session and 1,431 once invoked, about $0.0004 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 2026-08-31.
