Upcoming rocket launches

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint, and openWorldHint, so the description does not need to restate safety. It adds value by specifying the response includes 'liftoff times (UTC), pads, status and a live-tracking link', which are behavioral details beyond annotations. No contradiction.

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, well-structured sentence that front-loads the essential purpose and includes key details. No extraneous words; each part adds value.

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 list tool with no output schema and rich annotations, the description adequately covers what the tool returns and the optional filtering. It is complete enough for an agent to select and invoke the tool correctly.

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 100%, so the schema already documents both parameters (limit and provider). The description mentions 'optionally filter by provider/rocket name' but does not add new semantic information beyond what the schema already provides. Baseline score of 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 it provides a 'Live schedule of upcoming orbital rocket launches' with specific detail fields (times, pads, status, link). It distinguishes itself from sibling tools like get_iss_passes (ISS passes) and get_launch_news (launch news).

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 use when a user wants upcoming launch schedules and optionally filter by provider or rocket name. It does not explicitly state when not to use or provide alternatives, but the sibling differentiation and optional filter give sufficient context.

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