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

No annotations are provided, so the description carries the full burden of behavioral disclosure. 'Link Analyzer' reveals nothing about the tool's behavior—whether it's read-only or mutative, what permissions are needed, what it returns, or any side effects like rate limits. This leaves the agent with no understanding of how the tool operates beyond its name.

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?

While concise with just two words, this is under-specification rather than effective brevity. The description fails to convey essential information, making it inefficient for the agent's understanding. Every sentence should earn its place, but here the minimal content doesn't serve its purpose.

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 complexity implied by the tool's name among many web analysis siblings, no annotations, and no output schema, the description is completely inadequate. It provides no context on what the tool does, how it behaves, or what it returns, leaving the agent unable to use it effectively without guessing.

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 parameter 'url', with an example provided. The description adds no additional meaning beyond what the schema already documents (e.g., it doesn't clarify URL formats, constraints, or analysis scope). Since the schema fully covers the parameter, a baseline score of 3 is appropriate, as the description doesn't compensate but also doesn't detract.

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 'Link Analyzer' is a tautology that merely restates the tool name without specifying what action it performs or what resource it analyzes. It provides no verb or clear purpose, failing to distinguish this tool from its many siblings that also analyze various web properties (e.g., broken_links_finder, meta_tags_analyzer, redirect_checker).

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 description offers no guidance on when to use this tool versus alternatives. With 30+ sibling tools focused on web analysis (like broken_links_finder, meta_tags_analyzer, redirect_checker), there is no indication of what specific aspect of links this tool analyzes or when it should be preferred over other tools in the server.

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