# Mastra Brand Guidelines

## Overview

Access Mastra's brand identity, style resources, and writing guidelines.

**Keywords**: branding, Mastra brand, documentation style, visual identity, brand colors, typography, writing guidelines, technical writing

## Writing Style Guidelines

### Voice & Tone

Mastra's documentation is written for **engineers, not marketers**. Focus on implementation details and technical precision.

**Core principles:**

- Technical and direct
- Implementation-first, benefit-second
- Factual and descriptive
- No marketing fluff or superlatives
- Clear code examples

### What to AVOID

**❌ Marketing adjectives:**

- "powerful", "built-in", "complete", "out-of-the-box", "hands-on"

**❌ Enthusiasm language:**

- "Check out", "Learn more", "Explore", "essential", "offers"

**❌ Marketing jargon:**

- "your needs", "production-ready", "makes it easy", "choose the right...solution"

**❌ Vague benefit phrases:**

- "without changing your code", "automatically handles"

**❌ Generic benefit-focused sentences** that glide between benefits without diving into details

### What to DO

**✅ Use technical descriptions:**

- State what features exist and how they work
- Provide specific implementation details
- Use concrete code examples
- Explain mechanisms, not just benefits

**✅ Good examples:**

- "Agents use LLMs and tools to solve open-ended tasks. They reason about goals, decide which tools to use, retain conversation memory, and iterate internally until the model emits a final answer."
- "Mastra requires a storage provider to persist memory and supports three types: PostgreSQL, LibSQL, and Redis."

**✅ Formatting rules:**

- All H1 headings use sentence case (e.g., "Getting started", "Human in-the-loop workflow")
- Code examples should be practical and runnable
- Keep explanations concise and specific

## Key Features (Technical Descriptions)

When describing Mastra features, use these technical, factual descriptions:

**Agents:**

- "Agents use LLMs and tools to solve open-ended tasks. They reason about goals, decide which tools to use, retain conversation memory, and iterate internally until the model emits a final answer or an optional stop condition is met."

**Memory:**

- "Memory gives your agent coherence across interactions and allows it to improve over time by retaining relevant information from past conversations."

**Workflows:**

- "Workflows let you define complex sequences of tasks using clear, structured steps rather than relying on the reasoning of a single agent."

**Tools:**

- "Tools are functions that agents can execute. They extend agent capabilities by providing access to external systems, databases, APIs, or custom logic."

## Examples of Good vs Bad Writing

### ❌ BAD (Marketing-focused):

"This makes it easy to build AI applications that maintain meaningful conversations and remember important details, whether you're building a simple chatbot or a sophisticated AI assistant."

### ✅ GOOD (Technical, specific):

"Agents use a thread-based memory system. Each thread maintains conversation history and can optionally enable semantic recall to retrieve relevant context from past interactions using vector search."

### ❌ BAD (Vague benefits):

"Mastra makes it easy to deploy your AI agents to production without changing your code."

### ✅ GOOD (Specific implementation):

"Deploy agents using framework-agnostic adapters. The deployer package provides integrations for Vercel, Netlify, and Cloudflare Workers."
