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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only mentions the output content ('install command and a usage snippet') but does not disclose whether the operation is read-only, any side effects, permissions, rate limits, or output format. This leaves agents without important behavioral context.

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 sentence, front-loaded with the action ('Get'), and contains no redundant information. It is concise and well-structured, earning top marks for efficiency.

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 tool with one parameter and no output schema, the description provides a minimal but functional overview. However, it lacks information about the output structure, potential errors, or prerequisites for the id, leaving gaps that could cause misuse. It is adequate but not fully comprehensive.

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 schema defines a single required string 'id' with no description (0% coverage). The description's 'for an agent' implies that 'id' refers to an agent identifier, adding some meaning. However, it does not specify how to obtain the id, any format constraints, or examples, so the description only partially compensates for the schema's lack of context.

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 'Get the exact install command and a usage snippet for an agent' clearly states a specific verb (Get) and resource (install command and usage snippet) with a clear scope (for an agent). This distinguishes it from sibling tools like get_agent, list_agents, and search_agents, making its purpose unambiguous.

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 should be used when needing an install command for a particular agent, but it does not explicitly state when to use it versus alternatives like get_agent or search_agents, nor does it provide exclusions or contextual guidance. Usage guidance is present only by implication.

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