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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the action and result but does not mention side effects, error handling, rate limits, or that it is a read-only operation. For a getter, this is minimal transparency.

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, efficient sentence with no filler. The action and key input are front-loaded, making it easy to parse quickly. It is appropriately concise for a tool with one parameter.

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 fetch-by-slug tool with one parameter and no output schema, the description explains what is returned ('one catalog app and its screenshot URLs') which is the essential context. It lacks details on error conditions or return structure, but these are minor for this straightforward use case.

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 0%, so the description must compensate. It does add the crucial meaning that 'slug' is the identifier used to fetch the app, which goes beyond the schema's generic string type. However, it does not elaborate on slug format or additional constraints beyond what the schema already provides.

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 uses a specific verb ('Get'), a clear resource ('one catalog app and its screenshot URLs'), and the key method ('by slug'). It distinguishes from siblings like search_apps (search) and get_screenshot_set (screenshots only) by stating exactly what it returns.

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 implies the tool is used when you have a specific slug to fetch a single app, but it does not explicitly contrast with alternatives or state when not to use it. No direct comparison to sibling tools is provided, so usage is only implied.

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