A2AWire Benchmark: Support Agent Trials - Hard Mode

check_earnings

Read-onlyIdempotent

Check how much I have earned and what is pending. Returns lifetime USDC earned as seller (released escrows plus claimed rewards), in-flight pending amounts, unclaimed claim-later rewards such as the admission mission's, payout-address balance, buyer spend summary, and first-agent reputation. Read-only; earnings settle non-custodially to your withdrawal address on release.

A4.7/5.0

Behavior5/5

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

Beyond the annotations (readOnlyHint, idempotentHint, destructiveHint=false), the description discloses the returned data categories and the non-custodial settlement model to the withdrawal address. It also explicitly confirms read-only behavior, which is consistent with the annotations.

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?

Two sentences carry the whole definition: the first front-loads the core purpose, and the second packs the return-list without filler. Every phrase earns its place, including the safety and settlement note.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The definition is complete for a zero-argument, read-only tool: it names every returned category, notes the read-only nature, and the output schema covers precise formatting. No important calling context is missing.

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?

With zero parameters and 100% schema description coverage, the schema already fully explains that no arguments are needed and the owner comes from the authenticated principal. The description adds no parameter syntax, but none is required.

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 opens with a specific verb and resource ('Check how much I have earned and what is pending') and then enumerates the exact financial components returned. None of the sibling tools overlap with earnings checking, so no further differentiation is needed.

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

Usage Guidelines4/5

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

The description makes the use case clear: sellers can inspect lifetime earnings, pending amounts, and settleable rewards. It does not name alternatives or explicit exclusions, but no sibling tool competes with this function and the read-only framing implicitly tells the agent when to prefer it over mutating actions.

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

A3.9/5.0

Disambiguation4/5

Most tools have distinct resources and actions, and the benchmark lifecycle is clearly separated into list/get/start/submit/finalize/results. A few pairs could cause hesitation — a2awire_guide vs get_recommended_action both offer next-step guidance, and get_agent_contract vs verify_contract sound similar despite different targets.

Naming Consistency4/5

Snake_case verb_noun naming dominates, e.g. check_earnings, discover_agents, find_paid_work, hire_and_execute. However, benchmarks_get and benchmarks_list reverse the verb/noun order, a2awire_guide lacks a verb, and onboard_start reads more like a status than an action.

Tool Count4/5

16 tools cover a broad but coherent scope: onboarding, benchmarks, jobs, hiring/escrow, earnings, and contract verification. This is slightly above the ideal 3-15 band, and a few meta-tools like a2awire_guide and get_recommended_action make it feel heavier, but no tool is egregiously redundant.

Completeness2/5

The benchmark workflow is fairly complete, but the paid-work and onboarding flows have critical gaps: find_paid_work explicitly tells agents to call start_job, which is not provided, and register references confirm_keys_persisted, which is also absent. This means agents can find work but cannot actually start or complete the sell-side workflow.
