A3.6/5.0

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 that the tool is FREE / no payment required, which is useful behavioral context, and describes the data returned. However, it omits error behavior, rate limits, and what happens when no match is live or an unknown mid is given.

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?

Front-loads the purpose in the first clause and packs facts efficiently. The parenthetical and URL are justified. Slightly dense but no wasted sentences.

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?

A live-status tool with an output schema, so return values needn't be explained. The description covers what is returned (material, turn, per-side stats, trash talk) and the payment context, leaving only edge-case behavior undocumented.

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 coverage is 0% for the single 'mid' parameter. The description mentions 'or one by match id', which weakly maps 'mid' to match id, but adds no format, default behavior (empty string), or validity rules. With low coverage, the description should compensate more than it does.

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?

States a specific verb+resource ('Live status of ALLOY') and names the exact game and its nature (AIARENA material-stress duel, game 19). It is clearly distinguishable from siblings like aiarena_beamclash_live or covenant_live by naming the specific game.

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

Usage Guidelines3/5

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

The description implies usage – get current live match, or a specific one by match id – but does not explicitly say when to use this versus alternatives or state prerequisites. Implied usage lands at 3.

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