close_firefox_tab_group

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

With no annotations, the description carries the safety disclosure burden. It discloses two key side effects: every tab in the group is closed and the empty group is removed. It does not spell out reversibility or failure behavior, but the schema's confirmClose parameter already establishes that closing a group is irreversible.

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?

One sentence contains the key details: scope, exact-match requirement, verification, and the side effect of removing the empty group. There is no filler or redundant restatement of the tool name.

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?

The description plus high-coverage schema sufficiently describes the tool's behavior for a destructive group-close operation. It lacks explicit return-value or error semantics, but there is no output schema and the main usage edge cases, such as ambiguous titles, are covered in the schema.

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 schema already documents groupTitle matching, confirmClose irreversibility, and optional windowId with a condition. The description adds only the context of "exactly named" and "after verification", which is useful but not essential because the schema already provides the parameter meanings.

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?

Clearly identifies a specific destructive action: "Close every tab in one exactly named Firefox group (and remove the now-empty group)". This distinguishes it from sibling tools like close_firefox_tabs, rename_firefox_tab_group, and merge_firefox_tab_groups.

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?

The description implies the intended use: close an entire group by exact title rather than closing tabs individually. It does not explicitly state when to use this tool instead of close_firefox_tabs or other alternatives, nor does it warn against using it when only some tabs should be closed.

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