Pokemon deep-dive

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

With no annotations, the description carries the burden of behavioral disclosure. It usefully lists the data categories returned, which helps set expectations, but it does not mention data source, return format, error handling, or limitations for uncommon Pokemon or formats.

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, compact sentence that front-loads all key data categories. Every phrase contributes meaning and there is no redundancy or filler.

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 tool has no output schema, so the description should explain what the return contains; it does list the main categories. However, it omits important context like how the data is sourced, what happens for missing data, and how the default format is determined, leaving some ambiguity for a 'deep-dive' tool.

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 only 50%: the required 'pokemon' parameter has no schema description, and the description only says 'for one Pokemon,' offering minimal help. The 'format' parameter's semantics are fully covered by the schema, but the description adds no value for it, leaving the pokemon parameter weakly explained.

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 enumerates what the tool returns: common items, abilities, moves, spreads/natures, Tera types, and teammates for a single Pokemon in a VGC format. This is specific about the resource and scope, though it lacks an explicit verb like 'retrieves' and does not reference sibling tools.

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 provided about when to use this tool versus alternatives such as meta_snapshot, analyze_team, or calc_damage. The phrase 'for one Pokemon' implies a single-Pokemon analysis use case, but there are no explicit exclusions or references to sibling tools.

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