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

The only annotation is destructiveHint=false; the description adds the action set but does not explain that star/unstar change state, retry may trigger processing, or refresh reloads data. It also omits unstar and uses 'reload' for the enum value 'refresh', leaving behavioral effects underspecified.

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 front-loaded sentence with no filler. It is appropriately terse, though the terseness contributes to the missing detail elsewhere.

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 4-parameter tool with no output schema, no parameter descriptions, and only a destructiveHint annotation, the description is too thin. It leaves parameter roles, return behavior, and selection criteria unexplained.

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 0%, so the description must carry parameter meaning. It only gestures at the action parameter (star, retry, reload) and says nothing about media, kind, or company, nor does it cover the unstar/refresh enum values.

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 specific actions (star, retry, reload) on media and scopes them to the gallery view, so the resource and operation are clear. It does not distinguish this tool from siblings such as update_media, get_media, or list_media, so it stops short of a 5.

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?

No guidance is given on when to choose this over update_media, get_media, list_media, or other media siblings. 'From the gallery view' is context, not a usage rule or exclusion.

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