TDQS

A3.9/5.0

Behavior3/5

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so safety behavior is covered. The description adds useful context that this is a 'live scoreboard' and mentions the 'today' window, but it does not disclose auth requirements, rate limits, or other behavioral traits beyond what the schema and annotations already provide.

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

Conciseness2/5

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

The first two sentences are front-loaded and useful, but the description then lists every game enum value in full, duplicating the schema verbatim. That enormous list consumes most of the description and does not earn its place.

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?

For a read-only leaderboard with an output schema and complete annotations, the description covers the key distinctions, defaults, and usage context. It is slightly bloated by the game list, but it is complete enough for an agent to call the 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?

Schema description coverage is 100%, so the schema already documents all four parameters. The description adds a small amount of value via the default game value and an example call, but it also redundantly repeats the full game enum from the schema and does not explain 'limit' behavior.

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 opening states a specific resource ('Leaderboard') and the description immediately clarifies it is a live scoreboard for a game or tournament. It explicitly distinguishes itself from stats_leaderboard, stats_bot, and stats_game, so an agent can select it without inspecting sibling schemas.

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?

The 'WHEN' clause states exactly when to use this tool, and it names the alternatives plus their distinct purposes (Elo career ranks vs. single card stats). The scope values 'today|all' and the game-or-tournament_id choice are also explicit.

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