TDQS

A4.4/5.0
Behavior3/5

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. It states the tool's purpose and deprecation status but lacks details about what 'full DOM' includes (e.g., structure, limitations), performance implications, or error handling. The description adds some context (deprecation) but doesn't fully compensate for the missing annotation coverage.

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

Conciseness5/5

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

The description is extremely concise with just two sentences that each serve a distinct purpose: the first states the tool's function, and the second provides critical usage guidance. There is zero wasted text, and the information is front-loaded with the core purpose immediately clear.

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

Completeness4/5

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

Given the tool has 0 parameters, no annotations, and no output schema, the description provides adequate context for a simple, deprecated tool. It clearly explains what the tool does and why it shouldn't be used, which is sufficient for its complexity level. However, it could be more complete by explaining what 'full DOM' entails or linking to documentation for the replacement tool.

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

Parameters4/5

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

The input schema has 0 parameters with 100% coverage, so no parameter documentation is needed. The description appropriately doesn't discuss parameters, focusing instead on the tool's purpose and usage guidance. This meets the baseline expectation for tools without parameters.

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

Purpose5/5

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

The description clearly states the specific action ('Get the full DOM') and the target resource ('of the current page'), providing a complete verb+resource combination. It also explicitly distinguishes from its sibling 'get-context' by marking itself as deprecated and recommending the alternative, which enhances clarity about its role relative to other tools.

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

Usage Guidelines5/5

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

The description provides explicit guidance on when not to use this tool ('Deprecated, use get-context instead'), directly naming the alternative sibling tool. This gives clear, actionable advice for tool selection, helping the agent avoid deprecated functionality in favor of the recommended option.

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