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

Annotations already declare readOnlyHint=true, so the safe-read profile is covered structurally. The description adds the returned field set, which is genuine value given no output schema, but says nothing about auth requirements, rate limits, or pagination behavior despite exposing top/skip.

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?

A single lean sentence with the returned fields front-loaded and the endpoint appended. No waste, though the trailing 'Wild Apricot: GET ...' restates implementation detail an agent rarely needs.

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 read-only list tool with no output schema, the description helpfully enumerates the returned fields and notes the optional date filter. Remaining gaps (pagination semantics, auth) are minor for this tool class.

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 description coverage is 100%, so baseline is 3. The description only restates date-range filtering, adding no syntax or semantics beyond what the schema's start_date/end_date descriptions already provide.

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 (List) and resource (donations), and enumerates the returned fields — donor, amount, date, comments, donation field values. The resource is distinct enough from siblings like list_payments and list_invoices, though it never names those siblings to help route between financial list tools.

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 only usage signal is 'optionally within a date range', which is a parameter note rather than guidance. There is no statement of when to prefer this over list_payments or list_invoices, no prerequisites, and no exclusions.

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