Generate random faction assignments for Twilight Imperium 4th Edition
| Name | Required | Description | Default |
|---|---|---|---|
| players | Yes | Number of players (3-8) | |
| expansions | No | Expansion filter (e.g. ["base","pok"]). Default: all |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It only states the basic action ('Generate random faction assignments') without revealing important behaviors like whether factions are unique per player, how the expansions filter affects randomization, or whether the result is deterministic. This lack of detail is a significant gap for a tool that performs a random selection.
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, front-loaded sentence that states the core purpose without any extraneous information. Every word earns its place.
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 is relatively simple with two parameters and no output schema, but the description is minimal. It does not explain what the output looks like (e.g., a mapping of players to factions) or how the expansions filter behaves. Given the simplicity, the description is adequate but leaves room for clarification on return format and edge cases.
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?
The input schema provides 100% coverage for both parameters: 'players' (Number of players 3-8) and 'expansions' (Expansion filter, default all). The description does not add any parameter-level detail, but since schema coverage is high, a baseline score of 3 is appropriate.
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 function with a specific verb ('Generate') and resource ('random faction assignments for Twilight Imperium 4th Edition'). It distinguishes from sibling tools like ti4_draft_factions (drafting) and ti4_list_factions (listing) by focusing on random assignment.
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 provides no guidance on when to use this tool versus alternatives such as ti4_draft_factions or ti4_list_factions. It does not mention exclusions or context where another tool would be preferred, leaving usage entirely inferred from the tool name.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Most tools have clear prefixes (chess_, play_, hex_, oracle_, rpg_, ti4_) that separate concerns, but overlap exists between deprecated chess_* tools and the newer play_* equivalents, plus rpg_random_encounter and oracle_encounter both generate encounters. Descriptions help disambiguate, but the redundancy could mislead agents.
Many tools follow a domain_verb_noun pattern (hex_generate_map, play_get_moves, rpg_search_entities), but there are notable exceptions like dice_roll, game_deck_create, jam_status, and random_player_order that mix noun-first and verb-last conventions. The inconsistent ordering makes it harder to predict tool names.
81 tools is excessive even for a broad games toolkit; the deprecated chess_* tools alone add unnecessary bulk. While the scope is wide, the count exceeds practical limits and could be consolidated into fewer, more focused tools.
The toolkit covers a wide variety of game needs: dice, cards, hex maps, chess, RPGs, TI4, jam management, and galleries. Minor gaps like the score tracker lacking a retrieval method and the absence of some lifecycle operations keep it from being perfect, but core workflows are well covered.
