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

Annotations already disclose readOnlyHint, idempotentHint and destructiveHint=false, so safety is covered. The description adds domain meaning (a drop = one email template sent from the member's Gmail with per-person tracked links) but says nothing about the paged people listing behavior implied by page/limit, or what 'the same answers' actually contain. With annotations carrying the safety profile, a 3 fits.

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 sentences, front-loaded with the alias relationship the agent most needs. The second sentence is longer than strictly necessary for selecting the tool, but it earns its place by defining the returned entity.

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 getter with 4 optional, fully described params and no output schema, the description covers the entity conceptually but never indicates what the response shape is (drop metadata plus a page of people, presumably) or how name/campaignId resolve conflicts. Adequate but with a visible gap around return expectations.

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 name, campaignId, page and limit are fully documented at the schema level; baseline 3 applies. The description adds no parameter-specific guidance (e.g. name vs campaignId selection, pagination semantics), merely asserting argument parity with lnkdrp_get_drop.

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 identifies this as the older name of lnkdrp_get_drop with identical arguments and answers, which pins down both the verb (get/retrieve) and the resource without needing the schema. It then defines what a drop is entity-wise. It loses a point only because the action verb itself is inherited by reference to a sibling rather than stated directly.

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?

Explicitly tells the agent this tool is interchangeable with lnkdrp_get_drop ('the same arguments and the same answers'), which effectively resolves the alias/duplicate ambiguity among the ~120 sibling tools. It does not state when to prefer one name over the other, but for a pure alias those exclusions are moot.

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