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

Annotations already declare this a safe, idempotent, closed-world read, so the safety profile is covered. The description adds that the payload includes parts, bids, orders, and budget remaining, which is useful since there is no output schema, but it says nothing about access restrictions or errors.

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?

A single front-loaded sentence with no padding. Slightly vague framing ('every part') costs it the top mark, but it is efficiently sized for the information conveyed.

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 annotations covering the safety profile and no output schema to explain returns, the description does sketch the returned content. However, for a tool with a required, undocumented identifier it leaves the agent without enough to call it confidently.

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 0% and project_id is undocumented in the schema. The phrase 'Your project' weakly implies the id must belong to the caller, but no format, source, or lookup guidance is provided, so the description does not compensate for the coverage gap.

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 names a specific resource (a project) and enumerates its contents: parts, bids, orders, and remaining budget. That is enough to separate it from siblings like get_order, get_tender, or list_proposals, though the verb itself is implied rather than stated.

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 about when to call this versus alternatives such as list_proposals, my_tenders, or get_tender, nor any prerequisite or context statement. The agent must infer usage entirely from the name and the sibling list.

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