browser_group_end

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

With no annotations provided, the description carries the full behavioral burden. It usefully discloses that tabs stay open by default and only close when closeTabs=true, but it omits whether the group is deleted, whether groupId is required, and what happens if the group does not exist.

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?

Two short sentences with no wasted language. The action is front-loaded and the important default behavior about tabs is stated directly afterward.

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?

For a simple two-parameter tool with no annotations or output schema, the description covers the core purpose and the most important default. It is still incomplete because groupId semantics and the group's lifecycle after ending are not explained.

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%, so the description must compensate. It explains closeTabs clearly, but groupId is only indirectly referenced as 'its group' and is not described as optional or defaulting to the active group, leaving half the parameters under-specified.

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 states a specific action and scope: finishing the current task and stopping targeting its group. The sibling browser_group_begin makes the begin/end pairing inferable, but the description does not explicitly name or differentiate against that sibling.

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?

It gives implied usage with 'Finish the current task', which tells the agent when this tool is appropriate. However, it does not state when not to use it, what happens if no group is active, or explicitly route to browser_group_begin for the opposite action.

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