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

Annotations already declare readOnlyHint, idempotentHint and openWorldHint=false, so the safety profile is covered; the description adds genuinely new behavior (newest-first, permanent-first ordering) plus an auth precondition. It still says nothing about result size limits or pagination behavior, which is a modest gap rather than a serious one.

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?

One compact sentence in two clauses: what it returns with its ordering, then the precondition. Nothing is padding and the key scoping facts are front-loaded.

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?

An output schema exists so return values need no explanation, and the ordering/precondition are stated. However, for a paginated list tool whose two paging parameters have zero schema documentation, the description leaves the practical mechanics of retrieval unexplained.

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 0% for both parameters, so limit and offset are completely undocumented in the schema, and the description does not mention paging, defaults, or the 200 cap at all. The ordering sentence does not map onto either parameter, leaving an agent to guess how to page through results.

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 gives a specific verb+resource ('List the links') scoped to the connected Put It Online account, which cleanly separates it from get_link (singular) and delete_link. It does not explicitly name any sibling, so it falls short of a 5 despite the plural framing doing useful disambiguation work.

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?

It states the precondition 'Requires a connected account' and the ordering contract, which implies when the tool is usable, but it never says when to prefer this over alternatives (e.g. get_link for a single link) or whether the list is paginated/filterable. Usage is implied rather than guided.

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