minimize

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

With no annotations, the description does the important work of disclosing that the window is only hidden off-screen and the mode persists, implicitly reassuring that nothing is destroyed. It does not say whether the page keeps running, whether subsequent tools can still target the hidden window, or whether 'persist' survives across sessions — gaps that matter for an unannotated tool.

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, front-loaded with the action. The second sentence partly restates 'persist minimized mode' as 'only persist the mode', a mild redundancy but not enough to bloat the definition.

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 one-optional-parameter tool with no output schema and no annotations, this is roughly adequate, but it leaves open what happens to an already-hidden window, how the tab argument interacts with the window, and whether hidden windows remain interactable.

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% ('tab id, defaults to current'), so the baseline applies. The description adds nothing about the tab parameter, and notably never addresses why a window-level operation takes a tab id — a point the description could have clarified.

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 names a specific verb and resource ('Hide this native window') plus the state effect ('persist minimized mode'), which is enough to distinguish it from sibling 'maximize' and from 'close'/'close_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?

'Hidden windows stay off-screen and only persist the mode' implies the use case (reversibly getting a window out of the way without closing it), but there is no explicit when-to-use, no when-not, and no naming of 'close' or 'maximize' as the alternatives an agent should weigh.

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