TDQS

A3.8/5.0

Behavior4/5

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

Annotations already cover the safety profile (readOnly, idempotent, openWorld, non-destructive), so the bar is lower, and the description still adds genuine behavioral content: outputs are cited, notice requirements are retained, and it explicitly refuses to infer incumbent or eligibility. That last point is a real capability boundary an agent would otherwise assume. It does not mention latency or depth limits, keeping it at 4 rather than 5.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, no filler, with the positive capability statement front-loaded and the exclusion clause second. Every clause carries distinct information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so return-value explanation is unnecessary, and annotations plus full schema coverage handle safety and parameters. Combined with the description's scope and boundary statements, an agent has enough to invoke it correctly; only explicit sibling routing is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so both parameters (id and generation, including the 'retained generation UUID from search_opportunities' provenance) are fully documented in the schema. The description adds no parameter-level meaning beyond the schema, so baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description names a specific verb ('Build') and concrete artifact ('cited research brief') and enumerates its contents: retained notice requirements, exact award-number candidates, same-industry comparisons. It also bounds itself negatively ('Does not infer an incumbent or eligibility'), which helps distinguish it from inference-style siblings like explain_match, though no sibling is named directly.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage is implied rather than stated: an agent can infer this is the deep-research call to make after search_opportunities, and the negative clause warns of what it will not answer. There is no explicit 'use this instead of detail/document' routing or prerequisite statement, so selection still requires inference.

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