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

Annotations already declare readOnlyHint=true, destructiveHint=false, and idempotentHint=false, so the trailing 'Read-only.' sentence is largely redundant. The description does add useful context by stating the default status scope and the shape of returned fields, but says nothing about pagination behavior despite the cursor parameter.

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?

Two tight sentences with the resource scope front-loaded, then the default behavior. The closing 'Read-only.' is the one low-value fragment since annotations already assert it.

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?

With no output schema, the description helpfully names the fields returned (goal, amount funded, amount remaining, status), and the default-scope statement covers the main ambiguity. Pagination behavior and the meaning of each status enum value remain unstated, which is a minor gap for a 4-parameter list 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 description coverage is 75%, so the schema already documents q, cursor, and status. The description only restates the status default and lists result fields rather than adding syntax, matching, or format detail beyond the schema, so the baseline of 3 applies.

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 ('List products the public can fund toward laboratory testing') and enumerates the returned fields, so an agent knows it retrieves a collection with funding progress. It is implicitly distinct from checkout-creation and single-status siblings, but does not name them explicitly, so it falls short of full sibling differentiation.

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?

Gives one behavioral default ('Defaults to products currently accepting contributions') which helps an agent pick the right filter, but offers no explicit when-to-use/when-not guidance and does not mention the sibling tools that handle funding or status lookup. Usage is implied rather than stated.

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