grants_get_opportunity

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

No annotations provided, so description carries burden. It lists return fields (dates, award_ceiling, etc.) but does not mention side effects, rate limits, error handling, or whether data is historical or current. Adequate but not rich.

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?

One sentence with a list of key fields. No unnecessary words, front-loaded with action and resource.

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?

No output schema, but description lists 11 return fields, covering most of what a user needs. Lacks explanation of date formats, error states, or pagination (not applicable). Mostly complete for a fetch-by-id tool.

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 coverage is 100% for the one required parameter. Description adds minimal value: 'by id' repeats schema's 'opportunity id'. No extra constraints or examples.

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 clearly states 'Fetch full detail for a single grant opportunity by id' and lists specific fields returned. It distinguishes from sibling tools like grants_search (which likely returns multiple) and sam_get_opportunity (different platform).

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 tool versus alternatives (e.g., grants_search, sam_get_opportunity). The description implies use when you have a specific opportunityId but does not explain differences or prerequisites.

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