TDQS

C2.9/5.0
Behavior2/5

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

No annotations are provided, so the description carries the full burden. It mentions making a request to an external service but doesn't disclose behavioral traits like rate limits, network dependencies, error handling, or what 'could not be determined' means. The description is minimal and lacks operational context.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is appropriately sized and front-loaded, starting with the core purpose. The Args and Returns sections are structured but could be more integrated; overall, it's efficient with minimal waste.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given no annotations, 0% schema coverage, and no output schema, the description is incomplete. It lacks details on return format, error conditions, performance, or dependencies, making it inadequate for a tool that interacts with an external service.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must compensate. It explains that 'root_domain' is the root domain of the website to check, adding basic meaning. However, it doesn't clarify format (e.g., with or without protocol) or provide examples, leaving gaps in parameter understanding.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose: 'Check the status of a website' with the specific action of making a request to isitdownrightnow.com. It distinguishes the tool by specifying the external service used, though there are no sibling tools to differentiate from.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives, prerequisites, or limitations. It simply states what the tool does without context about appropriate scenarios or constraints.

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

B3.1/5.0
Disambiguation5/5

With only one tool, there is no possibility of ambiguity or overlap between tools. The single tool 'get_website_status' has a clear, distinct purpose that cannot be confused with any other tool in this set.

Naming Consistency5/5

The naming follows a consistent verb_noun pattern ('get_website_status'), and with only one tool, there is no inconsistency to evaluate. The naming convention is clear and appropriate for the tool's function.

Tool Count2/5

A single tool is too few for most server purposes, as it limits functionality and can lead to dead ends. For a website status checking server, additional tools like checking multiple sites, monitoring history, or getting detailed status information would be expected to provide a more complete surface.

Completeness2/5

The tool set is severely incomplete for the domain of website status checking. While 'get_website_status' covers a basic check, there are significant gaps such as batch checking, historical data retrieval, or status monitoring over time, which agents might need for more complex workflows.
