B3.2/5.0
Behavior2/5

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

With no annotations supplied, the description carries the full disclosure burden, and it says nothing about consequences: whether a click navigates, submits, or mutates state, whether it is reversible, whether it waits for page load, or what happens on an invalid element number. Only the bare mechanic is conveyed.

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?

One sentence, front-loaded with the action, with zero filler or redundant restatement of the name. Nothing could be removed without losing information.

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?

There is no output schema, so the description is the only place to explain what a click returns or what state the page is left in, and it omits that entirely. For an interaction tool with zero annotation coverage, the definition is thinner than an agent needs to call it confidently.

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 coverage is 100% and the single parameter's description ('Element number from the last read') already explains the value's origin and meaning. The phrase 'numbered element' in the description reinforces this but adds no new semantics such as index lifetime or staleness rules.

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 names a specific verb (click) and a specific resource (a numbered element on the current CrewNest page), so the action is unambiguous. It stops short of distinguishing itself from siblings such as crewnest_type, which likely acts on the same numbered elements, leaving the agent to infer the boundary.

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

Usage Guidelines3/5

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

Usage is only implied: 'numbered element' plus the schema's 'Element number from the last read' hints that a read must precede a click, but the description never states that prerequisite or when to prefer click over type/open. No exclusions or alternatives are given.

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