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

No annotations are provided, so the description carries the burden of explaining behavior. It clearly communicates that this is a read operation returning full project details, and specifically calls out video content description. It doesn't disclose error conditions or auth requirements, but for a simple get-by-ID tool the behavioral surface is adequately disclosed.

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 one short sentence that states the action, the resource, and a notable content detail. There is no redundancy or filler, and the key information is front-loaded.

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 single-parameter get operation with no output schema, the description gives enough context for an agent to select and invoke the tool: it will return full project details and includes video content description. It could be more explicit about the return shape, but 'full details' reasonably covers what an agent needs to know.

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%, and the single parameter 'id' is documented as 'Project ID; get valid IDs from list_projects'. The tool description itself adds no parameter-level meaning, but the schema already provides the necessary semantics, so the baseline score of 3 applies.

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') with a specific resource ('full details for a single project'), and adds a distinctive detail ('including video content description') that separates it from list_projects and other siblings. The intent is 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 this tool is for retrieving one project's full details, as opposed to list_projects for listing projects. The parameter schema even points users to list_projects for valid IDs, but there is no explicit statement about when to use this tool over alternatives or when not to use it.

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