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

With no annotations provided, the description carries the full burden and does well: 'Retrieve' clearly indicates a read-only operation, and the 'Returns' section discloses the output type (ability names and effect text). However, it does not mention potential errors, edge cases, or behavior for invalid inputs, which would make it more transparent.

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 succinct and well-structured: an opening summary sentence, followed by labeled Args and Returns sections. Every sentence carries necessary information with no fluff or redundancy.

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 tool with one parameter and an output schema, the description is nearly complete. It defines the input and the type of output. It does not elaborate on output structure, but that is covered by the output schema, and it does not mention limitations or related alternatives, which would improve completeness.

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?

Although schema coverage is 0%, the description fully compensates for the single parameter by stating 'name_or_dex: Pokemon name or national dex number.' This adds meaning beyond the schema, which only indicates type string. It is clear and practical, though it does not specify formatting for dex numbers (e.g., leading zeros).

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 with a specific verb and resource: 'Retrieve ability details for a Pokemon.' It distinguishes itself from sibling tools like get_pokemon and get_moves by focusing specifically on abilities.

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 by saying 'for a Pokemon,' but does not explicitly state when to use this tool over alternatives. It lacks exclusions or comparisons to sibling tools like get_pokemon or get_moves, leaving the agent to infer from the name and purpose.

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