Open an editorial page link

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

Annotations already declare readOnlyHint=true and openWorldHint=true, covering the safety profile. The description adds no behavioral details beyond that, such as side effects, external-opening behavior, auth needs, or rate limits, and instead restates the purpose.

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?

The description is a single front-loaded sentence with no filler, so it is concise and well structured. Its brevity comes at the cost of completeness, but that is addressed in other dimensions.

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?

Although an output schema exists and return values need not be explained, the input schema has three required parameters with 0% description coverage, and the description gives the agent almost no help in understanding page, category_index, and link_index. For a tool with indexed inputs, this leaves a significant usage gap.

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 description coverage is 0%, and the description does not explain the page enum values or what category_index and link_index mean. The phrase 'one link' loosely hints at link_index, but category_index and page remain opaque, so the description fails to compensate for the schema gap.

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?

States a specific verb ('Open') and resource ('the page behind one link of an editorial page's link list'), so the agent knows it is a navigation action rather than a list or search. It does not explicitly name sibling tools like tidal_list_page_links, but the link-following purpose is distinguishable.

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 use this tool versus tidal_list_page_links, tidal_list_page_category_items, or the browse_* tools, and no prerequisites or exclusions are stated. Usage is only implied by 'one link of an editorial page's link list'.

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