Behavior3/5

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

Absence of annotations means description carries full burden. 'Get' implies read-only, but no explicit statement of safety, side effects, or return behavior. Minimal but not misleading.

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

Conciseness3/5

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

Single sentence is concise but under-specifies for a tool with 25 parameters. Not verbose, but lacks structure.

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?

No output schema, no explanation of failure modes or output format despite the 'format' parameter. Incomplete for a complex tool with many optional parameters.

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?

With 96% schema coverage, the description adds no parameter meaning beyond the schema. Baseline 3 is appropriate as parameters are well-documented in the schema.

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 'Get element text or attributes' clearly states the action (get) and resource (element text/attributes), but it does not differentiate from sibling tools like 'snapshot' or 'find' which also retrieve element data.

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?

No guidance on when to use this tool versus alternatives. Siblings like 'find' or 'snapshot' exist but no context about selection criteria.

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