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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds meaningful context by specifying that an API key is required, limiting results to the caller's organization, and listing the exact output fields, which is helpful given there is no output schema.

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?

The description is a single sentence that front-loads the action and then packs scope, output fields, and authentication into a compact, readable form. There is no filler or redundant information.

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 zero-parameter, read-only list tool, this description is fully sufficient: it states what is listed, whose data is returned, the return fields, and the auth requirement. Sibling routing would be a nice enhancement but is not necessary for correct invocation.

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?

The tool has zero parameters, so the baseline is 4. There are no parameter semantics to explain, and the description instead clarifies the return payload, which is appropriate for this tool.

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 states a specific verb ('List'), a specific resource ('your organization's grant applications'), and enumerates the returned fields (id, grant title, status, document type, last updated). The emphasis on 'YOUR organization's' and the plural scope clearly distinguishes it from siblings like get_my_application and search_grants.

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?

The description implies when to use the tool through the scope 'YOUR organization's grant applications', but it does not explicitly mention alternatives or state when not to use it. The API key requirement is a useful precondition, but no guidance is given about choosing this over list_my_matches or search_grants.

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