wavexis_close_tab

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

Annotations already declare destructiveHint=true and idempotentHint=true. The description adds no extra behavioral context beyond stating the action. It does not disclose failure modes, permission requirements, or side effects.

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 short and front-loaded with the purpose, but it sacrifices completeness for brevity. The Args line is redundant with the schema, and the Returns line is minimal. Valuable space is wasted on the redundant Args line while critical parameter info is missing.

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?

Despite a simple tool and available output schema (returning JSON status), the description fails to mention the required session_id parameter, omits error handling, and provides no context about tab existence prerequisites. This leaves the agent underinformed.

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 description mentions tab_id but omits the required session_id parameter. With 0% schema description coverage, the description should compensate but instead provides incomplete and slightly misleading parameter information.

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 clearly states the action (close) and resource (tab) with the method (by ID). It distinguishes from sibling tools like wavexis_activate_tab and wavexis_new_tab. However, it omits the required session_id, which could cause confusion about the scope of the operation.

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?

No guidance is provided on when to use this tool versus alternatives (e.g., wavexis_new_tab to create, wavexis_activate_tab to switch). There is no mention of prerequisites or conditions for closing a tab.

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