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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, so the safety profile is covered; the description still adds ordering semantics ('most recent first'), the returned contents ('recoverable access code and intended recipients'), and an explicit non-mutation statement. It omits pagination or result-count limits, which is the main gap for an unbounded list tool.

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 scope and ordering before the filter and return details. 'Does not modify pages' is mildly redundant with the readOnlyHint annotation but is short and harmless.

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 carries the return-shape burden and does so ('each link, its recoverable access code and intended recipients'), plus ordering. For a list tool, the absence of pagination or maximum-result guidance is the remaining shortfall.

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% for the single 'project' parameter, and the description only restates it as an optional filter ('optionally filtered by project'). No additional syntax or matching semantics are added, so the schema does the heavy lifting.

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 links') plus scope ('published in the authenticated workspace') and ordering ('most recent first'). An agent can distinguish this from get_page or find_link, which fetch or search a single link rather than enumerating the workspace.

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 optional project filter implies when to use the narrow form, but there is no explicit when-not guidance and no mention of sibling alternatives such as find_link for targeted lookups. Usage must be inferred from the scope sentence.

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