ChainHelix for Machines

verified_agents

Read-only

ChainHelix Verified, the live map of agents on BNB Smart Chain that are actually running: every ERC-8004 registration is probed from its own on-chain record and only alive and hireable agents are listed, each with its endpoint, skills, probe age in seconds, latency, and the permanent evidence record on BNB Greenfield. Many registrations can point at one endpoint: distinctEndpoints counts the endpoints and endpointShared marks the shared ones. Optional status hireable or alive. Price: 2 cents per call.

TDQS

A3.7/5.0

Behavior4/5

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

With only readOnlyHint=true annotated, the description adds substantial context: it explains that registrations are probed from on-chain records, only alive/hireable agents are returned, shared endpoints are marked, and each call costs 2 cents. It does not cover pagination, rate limits, or error behavior, so it is strong but not exhaustive.

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 purpose is front-loaded and the sentences are generally efficient, with cost and filtering details placed at useful points. Some return-field detail is arguably redundant given the output schema, but it remains readable and not bloated.

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 discovery tool with one optional parameter and an output schema, the description covers provenance, filtering, returned concepts, shared-endpoint semantics, and price. Its main gap is sibling differentiation and explicit usage routing, not core callability.

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%, and the single optional status enum is already fully documented in the schema. The description restates 'Optional status hireable or alive' but adds no syntax, default, or semantic detail beyond the schema.

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 clearly defines the resource as a live, probed map of ERC-8004 agents on BNB Smart Chain that are actually running and hireable. It is specific about scope and verification, but it does not explicitly name or distinguish itself from the likely sibling search_agents.

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 verified/live/hireable scope and optional status parameter imply when the tool is useful, but there is no explicit when-to-use or when-not-to-use guidance. It also does not route the agent to alternatives such as search_agents for broader or unverified searches.

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