set_active_take

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

Annotations already declare idempotentHint=true and destructiveHint=false, so the safety profile is covered. The description adds minimal behavioral context by clarifying that the active take is 'which take plays,' but it discloses no additional side effects or playback implications beyond what annotations provide.

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 main sentence is concise, but the dangling 'Args:' heading adds clutter without delivering any content. The structure is incomplete rather than economically minimal.

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 tool with three required parameters, no output schema, and no parameter descriptions, this definition is incomplete. An agent cannot tell whether indices are zero-based, what each index refers to, or what the tool returns after setting the active take.

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%, and the description adds no parameter meaning. The trailing 'Args:' is empty, leaving track_index, item_index, and take_index completely unexplained. The parameter names are somewhat self-evident, but the description itself provides no value beyond 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 states a specific verb and resource: 'Set the active take of a media item (which take plays).' This clearly conveys the operation and its purpose. It does not explicitly distinguish itself from sibling getters like get_active_take or get_takes, so it misses the top score.

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?

There is no guidance on when to use this tool versus alternatives such as get_active_take, get_takes, delete_take, or crop_to_active_take. The operation is implied by the name and one-line description, but no context or exclusion is provided.

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