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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds genuinely useful behavioral context beyond that — result ordering ('most recent first') and a hard result cap ('capped at 50') — but is silent on pagination, auth requirements, and whether the cap can be raised.

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 front-loaded sentence with no wasted words; the parenthetical efficiently carries the two behavioral facts an agent needs. Nothing to trim and nothing buried.

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 an output schema present, return-value explanation is not required, yet the description still usefully states ordering and the 50-record cap. For a simple one-parameter read tool this is nearly sufficient; only the link_id semantics and pagination behavior remain unaddressed.

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?

The single parameter link_id has 0% schema description coverage, so the description carries the full burden. It only indirectly implies the parameter via 'for a link' and gives no type, format, or where-to-find-it guidance, which is thin for a fully undocumented required parameter.

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 states the concrete resource and its content ('Raw access logs for a link'), and the 'raw' framing implicitly distinguishes it from the sibling get_analytics_summary. It stops short of naming that sibling explicitly, so an agent must infer the contrast rather than being told it.

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?

There is no statement of when to use this tool versus get_analytics_summary or get_link. The description only characterizes the output, leaving the selection decision entirely to inference.

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