move_firefox_tab_to_window

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

No annotations exist, so the description carries the full transparency burden. It discloses that the tool moves a tab to another window, excludes grouping, and verifies the result, which adds useful context. However, it does not mention permissions, destructiveness (e.g., if the source tab is removed), or what 'verify' actually returns or checks.

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 redundant words. It efficiently states the core action, key constraint ('without grouping it'), and verification behavior.

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 moderately complex tool with a rich schema, the description successfully conveys the main purpose, the exact-identification constraint, and the verification behavior. The main gap is the lack of detail about what 'verify' entails or what the return value looks like, especially since no output schema is provided.

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 input schema covers all three parameters with detailed descriptions (selector forms, windowId, and index). The description's phrase 'exactly identified' loosely aligns with the schema's exact-match requirements but adds no new semantic detail beyond what is already in 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 uses a specific verb 'Move' and resource 'Firefox tab to another window', clearly stating the action and destination. It also adds 'without grouping it' to distinguish from group-moving tools and 'verify the resulting window' to define the outcome, making it stand out from sibling tools like move_firefox_tab.

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 phrase 'without grouping it' implies this is for cross-window moves rather than group moves, but there is no explicit comparison to alternatives such as move_firefox_tab or move_firefox_tab_to_group. It doesn't state when to prefer this tool over others or when not to use it.

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