Find optimal Cineplex showtimes

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

With no annotations, the description takes on the full burden. It transparently discloses key behaviors: seat quality filters (exclude front rows, side seats, require contiguous block) and default values for format, front rows, side seats, and contiguous seats. This goes beyond basic purpose.

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 sentence of 35 words, front-loading the core action. It is efficient and avoids fluff, though it could be slightly more concise by splitting into two sentences.

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?

No output schema is provided, and the description does not clarify the return format (e.g., list of showtimes with seat availability markers). For a tool with 7 parameters and complex logic, this omission leaves the agent uncertain about what to expect. Some return details are essential for correct usage.

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 100%, so the schema already documents all parameters. The description summarizes the seat logic but adds only modest extra context (e.g., 'good seats' definition). It does not introduce new parameter meanings beyond what the schema provides. Baseline 3 is appropriate.

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 clearly states the tool's action: given a movie, theatre, and date, find showtimes matching a format and check for good seats. It uses specific verbs ('find', 'check') and resources ('showtimes', 'seats'). The purpose is unambiguous and distinguishes it from sibling tools like find_theatres and find_movie.

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 context (when you have movie, theatre, date) but does not explicitly compare with sibling tools like get_optimal_seats or render_seat_map_html. No when-not-to-use advice or alternative recommendations are provided.

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