ticket_link

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

With no annotations provided, the description carries the full burden. It discloses important behavior: the link redirects to the cinema's own website, and seat selection/payment are not supported. This goes beyond a generic 'create a deep link' phrasing and sets accurate expectations about what happens after invocation.

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 compact and well-structured. It opens with the core purpose, follows with a key limitation, and then lists the parameters in a scannable Args block. Every sentence adds necessary information; there is no filler or redundant repetition.

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?

The tool has a simple shape, four fully documented parameters, a clear usage rule, and an output schema to describe return values. The description covers purpose, behavior, parameters, and timing. Nothing essential is missing for an agent to invoke it correctly in context.

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 define every parameter, and it does. Each argument gets a meaningful explanation and format: 'MovieGlu numeric cinema id', 'MovieGlu numeric film id', 'Showtime date YYYY-MM-DD', and 'Showtime time HH:MM (24h) exactly as published.' This fully compensates for the empty schema descriptions.

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 ('Deep link') and resource ('the cinema's ticketing page') with explicit pre-selection of film, date, and time. This clearly distinguishes it from siblings like cinema_showtimes or movie_showtimes, which are about fetching showtimes rather than linking out to purchase tickets.

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 gives a clear usage context: 'Use after presenting a showtime to the user.' It also clarifies that seat selection and payment are not handled by MovieGlu, which prevents misuse. It does not explicitly discuss when not to use it or name alternatives, but the guidance is sufficient for choosing it at the right moment.

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