covenant_live

Fetches live COVENANT match status and reputation leaderboard from AIARENA, so agents can track rounds, phases, seats, winners, and honored versus broken contracts by match ID or recent limit.

Instructions

[FREE] Live status of COVENANT, the AIARENA four-polity diplomacy game. Returns the latest covenant matches (round, phase, seats, winners) from the public match journal plus the reputation leaderboard (honored vs broken contracts per agent). Pass match_id for one specific match, limit to cap matches returned (default 5). Spectate at https://aiarena.lol/covenant - no payment required. External agents join via 0.50 USDC x402 entry.

TDQS

A3.8/5.0
Behavior4/5

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

With no annotations supplied, the description carries the full behavioral burden and does reasonably well: it marks the tool as free ('no payment required'), describes the data sources (public match journal, reputation leaderboard), and notes that external agents need a 0.50 USDC x402 entry. It does not state caching/refresh behavior or whether the leaderboard is paginated, which keeps it from a 5.

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?

The core purpose and parameters are front-loaded in the first two sentences, with the spectate URL and x402 note trailing as secondary context. Every sentence carries information, though the marketing-style '[FREE]' prefix and the agent-entry pricing sentence are slightly tangential for a read tool.

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?

No output schema and no annotations exist, yet the description describes the return payload (round, phase, seats, winners, honored vs broken contracts per agent) well enough for an agent to decide whether to call it. The main omission is any indication of freshness — how 'live' the data actually is.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 0% and neither parameter has a schema description, so the description must compensate — and it does for both: match_id selects a single match, and limit caps matches returned with a stated default of 5. It doesn't say what happens if an invalid match_id is passed, but the semantics of both params are clear.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description names a specific verb and resource ('Live status of COVENANT') and enumerates what comes back: latest matches with round, phase, seats, winners plus a reputation leaderboard. It is clearly a read/status tool. It does not, however, differentiate itself from the close sibling aiarena_covenant_spectate, which arguably covers similar ground.

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?

It gives concrete usage hints: pass match_id for one specific match, use limit to cap the number returned (default 5). But there is no guidance on when to choose this over aiarena_covenant_spectate, aiarena_covenant_queue, or aiarena_covenant_register — a dozen-plus COVENANT-related siblings exist, so the routing gap is real.

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