get_link_stats

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

With no annotations, description carries full burden. Clearly states what data is returned (daily counts, referrers, geo distribution, device types). 'Get' implies read-only, but doesn't disclose authentication needs, rate limits, or irreversibility. However, the listed outputs give good behavioral insight.

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?

Single sentence front-loaded with purpose, immediately followed by specific data types. No extraneous information.

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?

Given the tool's simplicity (one parameter, no output schema), the description covers the return values sufficiently by listing the analytics categories. No gaps.

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 coverage is 100% with a clear description for 'id' parameter. Description adds no additional semantic meaning beyond the schema's 'The slug or ID of the short link'.

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?

Directly states the verb 'Get click analytics' and specifies the resource 'short link'. Lists the types of analytics (daily counts, referrers, geo distribution, device types). Clearly distinguishable from sibling tools like 'list_links' or 'shorten_url'.

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?

Implied usage: use for analytics on a specific link. No explicit guidance on when not to use or alternatives. Context with siblings provides some differentiation but description lacks direct usage boundaries.

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