A4.1/5.0
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the burden. It discloses deprecation and removal, but does not mention any side effects or return format. For a simple getter, this is adequate but not rich.
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?
One sentence plus a clear deprecation note. Every word is useful; no fluff.
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 it's a deprecated tool, the description covers the essential alternative. It lacks parameter explanation but is otherwise reasonably complete for a simple getter.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, and the description does not explain the 'variant' parameter. The agent is left to infer what values are valid, making this a significant gap.
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 clearly states 'Get legal moves for a chess position' with a specific verb and resource. It also identifies itself as deprecated, which distinguishes it from siblings like play_get_moves.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly states 'DEPRECATED — use play_create_game + play_get_moves', giving direct alternative guidance. It also notes removal version, which helps with planning.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Disambiguation3/5
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.
Naming Consistency2/5
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.
Tool Count2/5
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.
Completeness4/5
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.
