Grant opportunity details

get_grant_record

Read-onlyIdempotent

Not affiliated with the U.S. government, GSA, or SAM.gov. Not a U.S. government service. Full details for one grant opportunity: eligibility applicant types, funding categories, award range, dates, and summary as recorded from the public posting. Present as information only; do not frame results as an eligibility determination or application recommendation. Verify every fact against the official grant posting before acting. Follow-ups within 30 minutes after a search ride free (up to 30 per search); otherwise one accepted call counts as one use. Every record carries a direct source link (or source name and record ID) so you can verify and cite the underlying record.

TDQS

A3.6/5.0

Behavior4/5

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

Annotations already declare readOnly/idempotent/non-destructive/openWorld, so the safety profile is covered, but the description adds genuinely new behavioral context: every record carries a source link or source name plus record ID for verification, plus the framing constraint that results must not be presented as an eligibility determination. It also discloses call accounting (one accepted call = one use, free follow-ups after a search), which annotations cannot express.

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?

Three leading sentences are legal/attribution boilerplate ('Not affiliated with the U.S. government, GSA, or SAM.gov. Not a U.S. government service.'), pushing the actual statement of purpose into the fourth sentence. The remaining sentences are dense and useful, but the definition is not front-loaded on what the tool does.

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 and the input schema fully documents the sole parameter, so the description needn't explain return shapes; it appropriately focuses on verification and citation behavior and use accounting. What's missing is only explicit sibling routing, which is a modest gap for a single-param read tool.

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% for the single required parameter, so the schema already explains that opportunity_number comes from a search result. The description adds no additional format, example, or constraint information beyond that, making baseline 3 appropriate.

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 resource (one grant opportunity) and enumerates the record fields returned: eligibility applicant types, funding categories, award range, dates, summary. Sibling differentiation is only implicit (it's the record fetch behind search_grants_gov/search_open_grants), and it never distinguishes itself from get_record or get_notice_record by name.

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 context is implied rather than stated: the parameter is described as 'Opportunity number from a search result' and the billing note about follow-ups within 30 minutes after a search makes clear this tool is called after a search. However, there is no explicit guidance on when to use this versus the other record-fetching siblings, and no stated preconditions or exclusions.

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