ungroup_firefox_tab

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

No annotations are provided, so the description carries the full burden. It states 'Remove' and 'verify the result', which indicates a post-check, but it does not disclose whether the tab remains open, error behavior, or reversibility. This is partial transparency.

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 sentence with a clear verb and scope, no filler. It front-loads the action and result, making it easy to parse.

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 tool is simple with one well-documented parameter, but no output schema or annotations. The description mentions verification but lacks edge-case behavior (e.g., what if the tab is not in a group, or the selector matches multiple tabs). It is minimally adequate.

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% with detailed descriptions for the selector forms. The description adds the phrase 'exactly identified' which reinforces the uniqueness requirement, but does not add new parameter-level semantics beyond the schema.

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 ('Remove'), the resource ('Firefox tab'), and the scope ('from its current group'), plus verification. It distinguishes from sibling tools like move_firefox_tab_to_group, which implies moving rather than removing.

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 context is implied: use when you need to remove a tab from a group. The phrase 'exactly identified' hints at the need for a precise selector, but there is no explicit guidance on when not to use it, such as when the tab isn't in a group, or comparison with alternatives.

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