mysql

mysql is a skill for Claude Code, Codex from ashish7802/awesome-api-skills. It costs 0 tokens per session (663 once invoked), scanned A, original, MIT.

A guide to MySQL, an open-source database used to store and retrieve application data. It covers setup, related tools, and production practices such as indexes and transactions.

In plain words
What is it for?
Starting a MySQL database, running it with Docker, improving read-heavy applications, and connecting it with tools such as Prisma or Drizzle.
Why use it?
It helps developers choose sensible database structures and avoid common performance and reliability problems when using MySQL.

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 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 9d 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.

Quick Start

MySQL is highly optimized for read-heavy web workloads. The InnoDB storage engine provides robust ACID compliance.

docker run -d -p 3306:3306 -e MYSQL_ROOT_PASSWORD=secret mysql:8

Production Patterns

Index Optimizations

MySQL heavily relies on clustered indexes (the Primary Key). Always define an auto-incrementing integer or sequential UUID (UUID v7) as your primary key to prevent massive index fragmentation and page splits during high-volume inserts.

Architecture & Scaling

Replication

MySQL's asynchronous replication is the standard for scaling read traffic. Write to the Primary node, and read from Read Replicas, but ensure your application can handle the replication lag (milliseconds).

Error Recovery

Use EXPLAIN to diagnose slow queries. If MySQL is performing a 'filesort' or full table scan, you are missing a critical composite index.

Security Notes

Disable local_infile to prevent arbitrary file reading vulnerabilities. Ensure sql_mode includes STRICT_ALL_TABLES to prevent MySQL from silently truncating strings that exceed column lengths.

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.
