PokéAPI — Pokemon Details

pokeapi.pokemon.detail

Read-onlyIdempotent

Retrieve detailed Pokémon data by name or Pokédex ID to get types, base stats, abilities, moves, height, weight, base experience, and sprite URLs.

Instructions

Get detailed data for any of 1025+ Pokemon by name or Pokedex ID. Returns: types (e.g. fire/flying), base stats (HP, Attack, Defense, Sp.Atk, Sp.Def, Speed), abilities (including hidden ability), first 20 moves, height (dm), weight (hg), base experience, and sprite image URLs. Examples: "pikachu" (id 25), "charizard" (id 6), "mewtwo" (id 150), "eevee" (id 133). Hyphenated names accepted: "mr-mime", "tapu-koko", "jangmo-o". No auth required; fair-use free API. Source: PokéAPI (pokeapi.co).

Input Schema

Name	Required	Description	Default
`name_or_id`	Yes	Pokemon name (e.g. "pikachu", "charizard") or numeric Pokedex ID (e.g. 25, 6). Names are case-insensitive. Hyphenated forms accepted (e.g. "mr-mime", "tapu-koko").

Output Schema

Name	Required	Description	Default
`error`	No	Present only when the call failed. Includes error code, message, request_id, and any provider-specific extras.
`result`	No	Tool response payload. Shape varies per tool — consult the tool description and inputSchema. May be an object, array, string, or number depending on the upstream provider response.

A4.4/5.0

Behavior5/5

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

The description goes well beyond the annotations by adding practical behavioral details: no auth required, fair-use API, 1025+ Pokemon covered, first 20 moves only, height/weight units, and accepted hyphenated name formats. This gives the agent useful operational context that annotations do not provide.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is front-loaded with the core purpose and return summary, followed by useful examples and constraints. It is a bit long but each section contributes meaningful information: return fields, accepted inputs, examples, auth status, and source.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple single-parameter read-only lookup, the description is complete: it covers input format, return contents, examples, auth, and usage constraints. The output schema and annotations cover the remaining structured details, so nothing essential is missing for an agent to call this tool correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema already describes name_or_id thoroughly, including case-insensitivity and hyphenated forms, so the schema carries the parameter-documentation burden. The description adds a few concrete examples (pikachu, charizard, mewtwo) but does not materially expand on the schema's parameter semantics.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description names a clear verb and resource: 'Get detailed data for any of 1025+ Pokemon by name or Pokedex ID.' It lists the specific data returned (types, stats, abilities, moves, height, weight, etc.), making it easy to distinguish from sibling tools like pokeapi.move.detail or pokeapi.pokemon.species.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description clearly states when to use the tool: whenever you need detailed Pokemon data by name or Pokedex ID. It does not explicitly name sibling alternatives or exclusion criteria, but the detailed return list makes the use case obvious enough.

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