At a glance

A skill your agent uses when needing to visualize database schema, generate ERD diagrams from Drizzle ORM schemas, or understand table relationships

Works in 4 steps: Find schema files - Locate Drizzle table… → Parse tables - Extract table names,… → Identify relations - Find .references()… → …

SKILL.md covers When to Use, Process, Mermaid ERD Syntax and Output Template, plus 2 more sections
Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Drizzle Erd is an agent skill from hiroppy/mf-dashboard. Use when needing to visualize database schema, generate ERD diagrams from Drizzle ORM schemas, or understand table relationships

Its SKILL.md is about 630 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Databases, covering Database schema design, ORMs and data access and Diagrams. It works with Drizzle ORM and Mermaid. The repository describes itself as: マネーフォワードMeを自動化、保有資産の可視化を行います. The licence is MIT.

When your agent uses it

Needing to visualize database schema
Generate ERD diagrams from Drizzle ORM schemas
Understand table relationships

Example prompts

“/drizzle-erd”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

Find schema files - Locate Drizzle table definitions (usually schema.ts or tables.ts)
Parse tables - Extract table names, columns, types, and constraints
Identify relations - Find .references() calls and relations definitions
Generate Mermaid - Output ERD in Mermaid syntax

What it can do on your machine

Read from SKILL.md and the folder at commit 855c3e7. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are mermaid and typescript).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Drizzle Erd loads about 627 tokens when it runs. Until then it costs about 35 tokens; SKILL.md has 136 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~35
When it runs · the whole SKILL.md, loaded when a task matches: ~627

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description: Use when needing to visualize database schema, generate ERD diagrams from Drizzle ORM schemas, or understand table relationships

Drizzle ERD Generator

Generate Mermaid ERD diagrams from Drizzle ORM schema files.

When to Use

Database schema visualization needed
Understanding table relationships
Documentation for DB structure
PR review of schema changes

Process

Find schema files - Locate Drizzle table definitions (usually schema.ts or tables.ts)
Parse tables - Extract table names, columns, types, and constraints
Identify relations - Find .references() calls and relations definitions
Generate Mermaid - Output ERD in Mermaid syntax

Mermaid ERD Syntax

mermaid

erDiagram
    TABLE_NAME {
        type column_name PK "Primary Key"
        type column_name FK "Foreign Key"
        type column_name UK "Unique"
        type column_name "nullable"
    }

    TABLE_A ||--o{ TABLE_B : "has many"
    TABLE_A ||--|| TABLE_C : "has one"
    TABLE_A }o--|| TABLE_D : "belongs to"

Relationship Notation

Symbol	Meaning
`\|\|`	Exactly one
`o\|`	Zero or one
`}o`	Zero or many
`}\|`	One or many

Type Mapping

Drizzle	Mermaid
`text()`	string
`integer()`	int
`real()`	float
`blob()`	blob
`boolean` mode	boolean

Output Template

mermaid

erDiagram
    %% Master Tables

    %% Transaction Tables

    %% Snapshot Tables

    %% Relations

Example

From Drizzle:

typescript

export const users = sqliteTable("users", {
  id: integer("id").primaryKey(),
  name: text("name").notNull(),
  email: text("email").unique(),
});

export const posts = sqliteTable("posts", {
  id: integer("id").primaryKey(),
  userId: integer("user_id").references(() => users.id),
  title: text("title").notNull(),
});

To Mermaid:

mermaid

erDiagram
    users {
        int id PK
        string name
        string email UK
    }

    posts {
        int id PK
        int user_id FK
        string title
    }

    users ||--o{ posts : "has many"

Quick Reference

Column Markers

PK - primaryKey()
FK - .references()
UK - .unique()
Add "nullable" comment if no .notNull()
