Output Schema

NameRequiredDescriptionDefault
noticeNoFree-tier upgrade notice; only when results are masked/delayed.
resultsYesTool result payload (read-only evidence). Shape varies by tool; scoring weights are never exposed.
history_limitNoPresent when the license limits history depth: earliest_allowed date, history_days and how many older items were removed.
deprecated_fieldsNoPresent only while a renamed key is still returned next to its replacement: field (old key), replacement (new key, same value), removal (ISO date after which the old key is gone).

C2.4/5.0
Behavior2/5

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

Annotations declare readOnlyHint=false, openWorldHint=false, and destructiveHint=false, but the description does not explain what non-read-only behavior this tool has, nor any side effects, permissions, or rate limits. It adds domain scope but little operational transparency beyond what the annotations already provide.

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

Conciseness3/5

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

The single sentence is not bloated, but it spends space on promotional phrasing like 'Comprehensive intelligence feed' instead of front-loading actionable usage detail. It is concise but not operationally structured.

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

Completeness2/5

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

An output schema exists, so return values need not be explained, but the description is still incomplete for a three-parameter tool with low schema coverage and a non-read-only annotation. An agent lacks enough information to confidently select and invoke it correctly versus siblings.

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

Parameters2/5

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

The tool has three parameters and only 33% schema description coverage; the description does not mention any parameter. It provides no compensation for the undocumented ticker and award_id parameters or for how date, ticker, and award_id interact.

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

Purpose3/5

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

The description identifies a domain (federal and defense procurement awards mapped to parent tickers) but uses the vague framing 'comprehensive intelligence feed' rather than a clear action verb. It does not clearly distinguish this tool from siblings such as get_beneficiary_tickers, get_company_exposure, or get_ticker_intelligence.

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

Usage Guidelines2/5

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, despite many closely related sibling tools. It also omits prerequisites, expected input scenarios, and any exclusion conditions.

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