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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=true, so the safety profile is covered. The description adds only "[scope: read]", which merely restates the readOnlyHint, and it says nothing about what a project record contains, what happens when the id is missing, or how remote or live the data is despite openWorldHint=true.

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 text is short and front-loaded, but the second fragment, "[scope: read]", is redundant with the annotations and earns no place. The remaining sentence is so terse that its brevity reflects under-specification rather than efficient economy.

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?

There is no output schema, so the description must explain what a returned project looks like, and it does not. For a lookup tool with open-world data access, an agent gets no sense of the response shape, failure modes, or how this differs from get_project_status.

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?

There is a single required parameter, and the schema description coverage is 100%, with the schema explaining where project_id comes from. The description contributes no additional meaning about the parameter, which is the expected baseline when the schema fully documents it.

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?

"Get one project" names a specific verb and resource, so the basic operation is clear. However, it does nothing to distinguish this from close siblings such as cloudhosting_get_project_status or cloudhosting_list_projects, so the agent must infer the boundary itself.

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?

There is no when-to-use guidance, no mention of prerequisites, and no pointer to alternatives. The only hint is inside the schema, which says project_id comes from cloudhosting_list_projects, and that is a parameter note rather than usage guidance for the tool.

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