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

With no annotations provided, the description carries the full burden of behavioral disclosure but fails completely. It doesn't indicate whether this is a read-only operation, what kind of output to expect, whether it makes network requests, what permissions might be needed, or any rate limits. The description provides zero behavioral context beyond the vague 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 technically concise with just two words, this represents under-specification rather than effective conciseness. The description doesn't front-load essential information or structure any meaningful content. Every word should earn its place, but here the words don't provide sufficient value to justify even their minimal presence.

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?

For a tool with no annotations, no output schema, and operating in a domain with many similar sibling tools, the description is completely inadequate. It doesn't explain what the tool returns, how it differs from other web analysis tools, what kind of redirect information it provides, or any behavioral characteristics. The description fails to provide the minimal context needed for effective tool selection and use.

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 input schema has 100% description coverage with a clear parameter 'url' documented as 'Example value: example.com'. The description adds no additional parameter information beyond what's already in the schema. With high schema coverage, the baseline score of 3 is appropriate since the schema does the heavy lifting for parameter documentation.

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 'Redirect Checker' is essentially a tautology that restates the tool name without providing any meaningful elaboration. It doesn't specify what the tool actually does (e.g., checks HTTP redirect chains, identifies redirect loops, analyzes redirect status codes) or what resource it operates on. While the name suggests it checks redirects, the description adds no value beyond the name itself.

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 provides absolutely no guidance about when to use this tool versus alternatives. Given the many sibling tools related to web analysis (like broken_links_finder, get_http_headers, dns_records_checker), there's no indication of what specific redirect-related problem this tool addresses or when it should be preferred over other tools that might also reveal redirect information.

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