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

Annotations already declare the operation as read-only, idempotent, closed-world, and non-destructive. The description adds useful value by enumerating what is returned: status, title, caption, settings, and scene progress, which helps the agent understand the response despite no output schema.

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 a single front-loaded sentence with no wasted text. The parenthetical list of returned fields is compact and informative.

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 simple read tool with annotations covering safety and no output schema, the description is mostly sufficient. The key gap is identifier behavior: both parameters are optional in the schema, but the description does not state that at least one is required or how to choose between ID and UUID.

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 carries the burden of explaining the two identifier parameters. It only says retrieval is by agent_office_film_id or agent_office_film_uuid, without clarifying format, optionality, precedence if both are supplied, or what happens if neither is provided.

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 uses a specific verb/resource pair ('One AI Office short film') and clearly scopes retrieval to a single film by ID or UUID. It is readily distinguishable from the sibling list_agent_office_films and from get_agent_office_plan.

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?

It indicates that the film can be retrieved by either agent_office_film_id or agent_office_film_uuid, which implies usage context. However, it does not state when to use this tool versus list_agent_office_films, nor does it explain how to obtain the identifiers.

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