ChainHelix for Machines

agent_standing

Read-only

The standing of one ERC-8004 agent on BNB Smart Chain from what it did, not what it declares: its evidence tier from the paid ERC-8183 hires ChainHelix funded and the delivery checks sealed on opBNB, whether it answers right now from the newest probe, and the feedback rows the registry holds for it graded by pattern (on BSC today they come from a rating farm). Every count carries its evidence: job ids, transactions, the registry read. Signed (EIP-191, the published ChainHelix statement signer), valid 24 hours. ChainHelix agents come back as first_party: evidence only, no verdict, no signature. Free without the signature at agents.chainhelix.io/standing/. Price: 2 cents per call.

TDQS

A4/5.0

Behavior5/5

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

With readOnlyHint already present, the description adds substantial behavioral context beyond annotations: evidence sources, signed EIP-191 output valid 24 hours, special handling for ChainHelix agents as first_party with no verdict or signature, free unsigned access, and a 2-cent per-call price. It discloses cost, auth/signing requirements, and edge-case behavior clearly.

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 description front-loads the core purpose and packs in relevant evidence, signature, pricing, and special-case details without obvious filler. It is dense and could be structured more cleanly, but each sentence contributes useful context for an agent deciding how to call it.

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?

Given the presence of an output schema, readOnlyHint, and full schema description coverage, the description supplies the missing behavioral context: evidence provenance, signature validity, pricing, and ChainHelix-agent handling. An agent has enough information to understand what the call returns and the operational constraints.

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 coverage is 100%, and the schema already defines id as 'the ERC-8004 token id on BNB Smart Chain.' The description reinforces that this is one agent and uses <id> in the free URL, but adds no format or validation detail beyond the schema, so the baseline of 3 is appropriate.

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 states a specific verb and resource: the standing of one ERC-8004 agent on BNB Smart Chain, with concrete evidence sources, a live probe check, and registry feedback rows. The word 'one' implicitly distinguishes it from bulk standing tools, though it does not explicitly name sibling alternatives such as standing_bulk or agent_report.

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?

Usage is implied by 'one ERC-8004 agent' and the URL pattern for free unsigned access, but the description does not explicitly say when to use this tool versus standing_bulk, standing_watch, verified_agents, or agent_report. It gives context about ChainHelix agents and signature validity, but no direct tool-selection guidance.

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