mysql-docs

mysql-docs is a skill for Claude Code, Codex from cookieMonsterDev/agents-skills. It costs 82 tokens per session (1,423 once invoked), scanned A, original, MIT.

A reference guide for MySQL, a relational database system that stores structured data in tables and is queried with SQL.

In plain words
What is it for?
Use it to find guidance on SQL, table design, indexes, transactions, users and permissions, backups, replication, InnoDB, connectors, configuration, performance, and troubleshooting.
Why use it?
It helps answer MySQL questions using the right official documentation and version-specific behavior instead of relying on memory or PostgreSQL assumptions.

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-docs 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 4d 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.

How it starts

The opening of the file, as written. The whole thing — 116 lines — stays where its author put it; the contents beside it link to each section on GitHub.

MySQL questions are easy to answer from stale memory, PostgreSQL assumptions, or the wrong major version. Use this skill to ground answers in the official MySQL documentation and return the closest authoritative page instead of generic relational-database advice.

When to Use

Use this skill when the request is about:

  • MySQL concepts, terminology, or product boundaries
  • SQL syntax, DDL, DML, queries, data types, functions, operators, or views
  • Indexes, full-text search, transactions, isolation levels, or locking
  • Query performance, optimizer behavior, EXPLAIN output, or statistics
  • Installation, server setup, configuration options, or runtime operation
  • Users, privileges, roles, authentication, encryption, or auditing
  • Routine maintenance, backups, restore, or binary logs
  • Replication, Group Replication, InnoDB Cluster, InnoDB ReplicaSet, or failover
  • InnoDB storage engine behavior, tablespaces, and buffer pool tuning
  • Client libraries and connectors: Connector/J, Connector/Python, Connector/NET, ODBC
  • MySQL Shell, Workbench, Router, Operator for Kubernetes, or NDB Cluster
  • MySQL HeatWave, Enterprise features, or cloud deployment guides
  • Release notes, version-specific behavior, or error codes

Do not use this skill for:

  • PostgreSQL SQL, schemas, or server behavior. Use the appropriate postgresql-*-docs skill instead.
  • MongoDB document modeling or aggregation. Use mongodb-docs instead.
  • Amazon RDS or Aurora console operations when the question is provider-specific rather than MySQL behavior.
  • MariaDB-only features unless the user explicitly asks about MySQL-compatible behavior documented by Oracle.

Workflow

1. Classify the request

Decide which bucket the question belongs to before searching:

  • Getting started and tutorials
  • SQL language and data modeling
  • Query writing and performance
  • Server administration and configuration
  • Security, users, and authentication
  • Backup, restore, and reliability
  • Replication and high availability
  • Storage engines and InnoDB internals
  • Connectors, APIs, and client tools
  • Cloud, HeatWave, or Enterprise features
  • NDB Cluster, Router, or Kubernetes operator
  • Reference, error codes, or release notes

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.
