switch_to_parent_frame

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

With no annotations, the description discloses the key behavioral trait: it is only supported in IE context and behaves like switch_to_default_content. This provides useful context beyond the bare action, though it doesn't mention error cases or effects in non-IE contexts.

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 two concise sentences, front-loaded with the primary purpose and followed by the key limitation. Every word adds value with no redundancy.

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 zero-parameter tool with no output schema, the description sufficiently covers what the tool does and its limitation. It is complete for its simplicity, making the tool's behavior clear to an agent.

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 tool has zero parameters, and the input schema is empty. The description adds no parameter information, but none is needed. Baseline 4 is appropriate given the description is not required to explain parameters that don't exist.

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 ('Switch context to the parent frame') and specifies the target (current frame's parent). It distinguishes itself from sibling tools like switch_to_frame and switch_to_default_content by noting the IE-only behavior and equivalence to switch_to_default_content.

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 explicitly states the only supported context ('Only supported in IE context') and mentions behavioral equivalence to switch_to_default_content there, giving a clear constraint and a reference alternative. It does not explicitly say when not to use it, but the IE limitation implies it.

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