imposter-game-mcp

generate_game_words

Generate a secret word pair and assign roles for your Imposter Game session using a category and player count.

Instructions

Generate a set of words for an Imposter Game session. Given a category and player count, this returns a secret word pair (one for civilians, one for the imposter) and assigns the roles to a list of players.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

A4/5.0

Behavior3/5

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

No annotations are provided, so the description must fully disclose behavior. It does describe the core output behavior (returns word pair, assigns roles) but does not mention side effects, persistence, or failure modes. It also doesn't clarify whether 'assigns the roles' means persistent state or just part of the return value. This is a partial disclosure.

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

Conciseness5/5

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

The description is two sentences: the first states the general purpose, the second details the output. Both are essential and concise, with no filler or repetitive content. It is well-structured and front-loaded.

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

Completeness4/5

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

Given there is no output schema, the description explains the return value sufficiently at a high level (word pair, role assignment). However, it lacks details about the exact return structure (e.g., JSON format, how players are listed) and does not mention the need to call get_categories first (though the schema does). This is slightly incomplete but acceptable for a simple tool.

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 schema already provides 100% parameter coverage with descriptions for category and playerCount, including an example category ID and a minimum for playerCount. The tool description only restates the parameter names without adding additional meaning, syntax, or format details, so it does not exceed the schema's baseline.

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 uses a specific verb ('Generate') and resource ('words for an Imposter Game session'), and clearly states the return value: a secret word pair and role assignments. This distinguishes it from the sibling tool get_categories, which is about fetching categories.

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 provides clear context: it is used when you have a category and player count for an Imposter Game session. It implies the prerequisite of knowing a category, but it does not explicitly mention alternatives or when-not-to-use conditions. The sibling get_categories is present but not referenced in the description.

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