get_expo_quick_start

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

With no annotations, the description partially conveys the tool is a read operation ('get'), which is positive. However, it lacks details on authentication, rate limits, or whether the guide content varies by platform beyond what the parameter implies. The description is minimally transparent.

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 a single concise sentence with no wasted words. It is front-loaded with the core purpose. However, it could benefit from slight expansion to improve completeness without losing conciseness.

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?

Given the absence of an output schema and annotations, the description is too brief. It does not explain what the guide contains (e.g., steps, code snippets) or mention any platform-specific details beyond the parameter. For a content-returning tool, this is insufficiently complete.

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?

Schema description coverage is 100%, with the parameter 'platform' described as 'Target platform' and an enum. The tool description adds no additional meaning beyond the schema, so baseline score 3 is appropriate. The schema already handles parameter semantics adequately.

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 retrieves a quick start guide for Expo, which is a specific resource and verb. It distinguishes from sibling tools (search, doc content, API reference) by focusing on 'quick start' rather than detailed docs or searching. However, it could be more precise about what the guide contains.

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?

No guidance is provided on when to use this tool versus alternatives like search_expo_docs or get_expo_doc_content. The description does not mention context, prerequisites, or exclusions, leaving the agent without selection criteria.

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