get_space_platforms

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

The description discloses the output fields but omits the filtering behavior of the 'force' parameter. Since the description says 'List all space platforms' while the parameter defaults to 'player', it could imply a global list when in reality it filters. With no annotations, this omission is a moderate gap.

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, direct sentence with no extraneous words. It front-loads the primary action and key output, fitting the minimalist structure expected for a simple tool.

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 only one optional parameter and no output schema, the description reasonably conveys the return shape. However, 'hub info' is somewhat vague, and the filtering aspect is missing, preventing a perfect score.

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% and the parameter description in the schema already explains 'force name' and default. The description adds no additional meaning beyond what the schema provides, meeting the baseline but not exceeding it.

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 lists all space platforms and enumerates the displayed fields (name, state, location, hub info). It is distinct from sibling tools like get_planets which lists planets, avoiding confusion.

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?

No guidance is given on when to use this tool versus alternatives like get_planets or get_surface_info. The description does not mention any prerequisites or complementary tools, leaving the agent to infer usage from context.

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