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

The annotations already declare readOnlyHint, idempotentHint, non-destructive, and closed-world behavior, so the safety profile is covered. The description adds useful scope by saying it aggregates parts, bids, orders, and remaining budget, but it does not mention permissions, pagination, or return structure.

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 compact phrase with no wasted words. It is front-loaded with the project scope, though the wording is somewhat informal rather than operationally precise.

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?

With no output schema, the description should clarify what the agent receives. It lists returned sections but does not explain structure or depth, which is only minimally sufficient for a one-parameter read tool.

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%, and project_id is already documented in the schema with an example format. The description adds no additional parameter meaning, which is acceptable given the schema baseline.

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 implies a project overview by listing contents (parts, bids, orders, remaining budget), but it never uses an explicit retrieval verb and 'Your project' is vague. It gives a sense of scope, yet does not clearly distinguish the tool from siblings such as get_order or get_tender.

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 guidance on when to use this tool versus alternatives like get_order, my_orders, or list_proposals. The description does not state prerequisites or exclusions, leaving usage entirely implied by the name.

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