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

With no annotations, the description carries the burden, and it does disclose the content returned (options, users with roles, task summary), which implies a read operation. However, it says nothing about permissions/account scoping requirements, side effects or absence thereof, or response shape beyond the field list.

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?

One compact sentence with the lookup key and returned content front-loaded; nothing is wasted. The noun-phrase opening ('Extended project information') lacks an explicit verb, a minor clarity cost.

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 two-parameter read tool with no output schema and no annotations, the description should at least carry the return-value and safety burden. It lists returned fields, which helps, but omits permission/account context and any routing guidance to alternatives.

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%, so both account_code and project_relative_id are already documented in the schema. The description only reinforces 'by relative ID'; it adds no format or constraint detail beyond the structured fields, so the baseline 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 identifies the resource (a project), the lookup key (relative ID), and the payload (options, users with roles, task summary), so an agent knows this returns an extended detail view. It does not explicitly distinguish itself from near-siblings like GetProjectTreeTool or ListProjectsTool, which weakens it slightly.

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 statement of when to use this tool versus ListProjectsTool/GetProjectTreeTool, nor prerequisites such as needing a project relative ID already obtained elsewhere. Usage is only implied by the 'by relative ID' phrasing.

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