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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=true, so the safety profile is covered. The description reinforces this with 'No business data is changed' and adds the useful detail that field selection matches the list tool. It stops short of covering error behavior (e.g., what happens for an unknown or malformed ID) or return shape, leaving gaps beyond what annotations provide.

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?

Three short sentences, front-loaded with the core action and scope. The final sentence about no data being changed is largely redundant with readOnlyHint but costs little; there is no filler or restated title beyond that.

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 exists, and 'same selected fields as the corresponding list tool' defers the return shape to a sibling rather than describing it, so an agent cannot know what fields come back without inspecting list_products. Error/not-found behavior and pagination are irrelevant here, but the undefined return content and unspecified ID format keep this at minimum-viable.

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?

With one parameter and 0% schema description coverage, the description carries some of the burden: it clarifies that 'id' is a Givecloud ID rather than an external or arbitrary identifier. The regex pattern constraint lives only in the schema, and the description adds no format guidance, so it only marginally compensates for the coverage gap.

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?

States a specific verb and resource ('Read one fundraising product') and scopes it to a single record by Givecloud ID, which implicitly contrasts with the list_products sibling. It doesn't explicitly name list_products as the alternative, but the singular 'one' makes the distinction clear.

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?

Usage is implied by 'Read one ... by its Givecloud ID' and the note that results match the corresponding list tool, hinting that this is the single-record counterpart to list_products. However, there is no explicit when-to-use/when-not-to-use guidance or named alternative for cases like bulk retrieval or lookup by other fields.

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