getProject

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

With no annotations, the description carries the full burden. It correctly states it retrieves details, implying a read-only operation, but does not disclose any additional behavioral traits (e.g., authentication, rate limits, or that it returns the entire project object). It is adequate but not informative beyond the obvious.

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 extremely concise with two bilingual sentences, no fluff, and front-loads the essential purpose. Every word adds value.

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 simplicity of a get-by-ID tool with one required parameter and no output schema, the description is fairly complete. It could mention the return format or typical fields, but the word 'details' plus the schema makes it understandable. The large sibling set does not require more detail for this straightforward operation.

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 coverage is 100% with a clear description for projectId. The description adds 'details' which implies the output contains all project fields, but this is a slight addition. According to calibration, baseline is 3 for high schema coverage, and the description provides marginal extra meaning.

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 verb 'Retrieves' and the resource 'details of a specific TestRail project by ID'. It distinguishes itself from sibling tools like getProjects (plural, returns list) and other get* methods by specifying a single project retrieval by ID.

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 vs. alternatives like getProjects or getCase. The agent is not informed about context such as needing the project ID or that this returns full details, but there is no explicit comparison or when-not-to-use advice.

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