play_content_save

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

No annotations are provided, so the description carries the full disclosure burden. It usefully discloses that the tool saves and then dismisses a console dialog, but it omits permissions, failure behavior, and other mutation side effects.

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 front-loaded with the core action and then provides necessary button details without excess. It is appropriately sized, though the parameter detail is slightly fragmented.

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?

With an output schema present, return values need not be explained. However, given no annotations and 0% schema description coverage, the description should cover the required package_name parameter and better situate the tool among siblings, which it does not.

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 description coverage is 0%, so the description must compensate. It does this well for the button parameter by listing exact pt-BR labels and their meanings, but it says nothing about the required package_name parameter, leaving a significant gap.

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 states a specific verb and resource: saving the open declaration and dismissing the subsequent dialog. It is clear what the tool does, though it does not explicitly distinguish itself from siblings such as play_content_answer or play_content_options.

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 usage only through 'the open declaration,' but gives no explicit when-to-use guidance or alternatives. The button options explain parameter choices within multi-step wizards, not when to select this tool over related Play Content tools.

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