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

With no annotations, the description carries the full burden. It discloses the extraction behavior and whitespace cleanup, which is useful, but omits what happens when no page is open, failure/error behavior, and any permission considerations. Adequate but incomplete for a zero-annotation tool.

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 stating the action, with no wasted preamble. The trailing clause about returning content 'to the LLM to provide an answer' is mildly redundant but not harmful.

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?

An output schema exists, so return values need not be described, and there are no parameters to document. The main remaining gap is state-dependence (what it requires the browser to already be showing), which is only implied rather than guaranteed.

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?

The schema has zero parameters, so the baseline of 4 applies. Nothing about parameters needs explaining and the description does not confuse the matter.

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 and resource: it extracts the visible text from the current forecast page open in the browser and returns a cleaned version. That is clear and distinguishable from open/enter/select siblings in the pipeline, though it never explicitly names how it differs from them.

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?

Usage is implied rather than stated: it works on the page 'opened in the browser', so the agent can infer it must run after opening and selecting a city. There is no explicit statement of prerequisites, exclusions, or what to do instead if the page is not ready.

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