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

With no annotations, the description carries the full behavioral burden. The field list usefully previews the returned record's scope, which matters because there is no output schema, but it says nothing about read-only semantics, auth, or what happens with a missing or invalid id. A modest amount of value added, with clear gaps.

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 fragment with zero filler; every listed item is a real content dimension of the award record. It is a noun phrase rather than a sentence, so it reads slightly telegraphic, but nothing is wasted.

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 one-parameter lookup tool this is nearly adequate, and the field list substitutes for the absent output schema. However, it never states that id is the sole selector, nor that required-parameters is empty in the schema, leaving ambiguity about how the award is identified.

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?

Only one parameter and schema description coverage is 100%, so the schema already documents the id including its CONT_AWD_ example format. The description adds no further meaning about the id (e.g., whether it is required or where to obtain it). Baseline 3 applies when the schema does the work.

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 phrase "One federal award" names a specific resource and, by using the singular, implicitly distinguishes it from the sibling federal_awards list tool. The field enumeration (amounts, period, agencies, recipient and parent, competition, set-aside, subawards) makes the retrieval target concrete. It lacks an explicit verb like "retrieve", which keeps it short of a 5.

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 on when to use this versus federal_awards, company_federal_awards, federal_recipient, or federal_spending. The only implied usage cue is the schema's example id format (CONT_AWD_...), and even that is not referenced in the description. An agent must infer that this is the single-award lookup when it has an award id.

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