jane_app_click

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

With no annotations, the description carries the full burden of behavioral disclosure. It says nothing about what a click does to page state, whether navigation invalidates previously observed element numbers, or how failures (stale/absent element) are surfaced.

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?

A single front-loaded sentence with no wasted wording. It is efficient but too sparse to earn a 5, since brevity here comes partly at the cost of missing guidance.

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?

This is a state-changing interaction tool with no annotations, no output schema, and a hard dependency on a prior read. The description omits both the prerequisite workflow and the post-click effect, which an agent needs to sequence calls correctly.

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?

Schema coverage is 100% and the element property already explains it is 'Element number from the last read.' The description reinforces the numbering is relative to the current page but adds no format, range, or staleness semantics beyond the schema, so the baseline 3 applies.

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 gives a specific verb+resource pair, 'Click a numbered element,' scoped to 'the current Jane App page,' which naturally separates it from jane_app_type (keyboard input) and jane_app_read (page inspection). It does not explicitly name a sibling or state exclusions, so it stops short of a 5.

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?

There is no guidance on when to click versus when to use jane_app_type or when to re-read the page first. The only sequencing hint, 'Element number from the last read,' lives in the schema property description rather than the tool description, leaving the prerequisite workflow to inference.

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