Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already include readOnlyHint=true, so the read-only behavior is disclosed. The description adds context about the content brevity ('condensed 2-minute guide') and scope (minimal examples, core syntax), which helps set expectations about the return value. No contradiction with annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two sentences: the first states the primary function and content, the second provides usage context. It is front-loaded with the main verb and contains no unnecessary filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple, zero-parameter read-only tool, the description adequately covers both the return content and the intended use case. However, it does not explicitly mention how this relates to other guides (e.g., get_comprehensive_example), which could provide more complete orientation for an agent.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool has zero parameters, and the schema is empty. With no parameters to document, the description is not required to explain them. The baseline score of 4 applies, and the description's mention of content type is sufficient.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool returns a 'condensed 2-minute quick-start guide' with specific content components (minimal working examples, core syntax, key concepts). The verb 'Returns' specifies the action, and the term 'condensed' distinguishes it from more comprehensive sibling tools like get_comprehensive_example.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides explicit usage guidance: 'Use this for rapid learning when you need to generate simple diagrams quickly.' This implies a context of quick, simple tasks, but does not explicitly name alternative tools like get_comprehensive_example or get_generator_guide, so it lacks a direct exclusion statement.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
