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

No annotations are provided, so the description carries the behavioral burden. It discloses the output shape (a 2D grid grouped by stability categories) and the filtering dimensions, but it does not explain edge cases, return format details, or what happens when no filters are provided.

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, information-dense sentence. It front-loads the core purpose and packs the filter dimensions and output grouping into one clean statement with no wasted words.

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 description is adequate for a tool with three optional filters and no output schema, but it leaves gaps: the response format is not described, and there is no mention of defaults or constraints. For a medium-complexity tool with no annotations, a bit more context would be expected.

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?

All three parameters already have clear descriptions in the input schema, so schema coverage is 100%. The description essentially restates the same filter concepts without adding new parameter-level meaning, which meets the baseline but adds little beyond the schema.

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 ('Generate') and names the exact resource ('2D Speed vs Stability Flight Grid'), including the stability groupings. This clearly distinguishes it from sibling tools that look up individual discs, compare discs, or provide rankings.

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 gives clear context on when to use the tool: for any brand, category, or specific speed rating. It does not explicitly mention alternatives or when-not-to-use scenarios, so it falls just short of full guidance.

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