Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

hol-resolve scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

/hol-resolve

Resolve an agent by its UAID (Universal Agent Identifier).

Description

This command resolves a UAID to get full agent details including capabilities, protocols, and connection information. Uses the RegistryBrokerClient from @hashgraphonline/standards-sdk.

Usage

/hol-resolve <uaid>

Examples

/hol-resolve hcs10://0.0.123456/my-agent
/hol-resolve erc8004://0x1234.../agent-name

Implementation

When this command is invoked:

  1. Initialize the client:

    import { RegistryBrokerClient } from '@hashgraphonline/standards-sdk';
    
    const client = new RegistryBrokerClient({
      baseUrl: 'https://api.hol.org',
    });
    
  2. Resolve the UAID:

    const agent = await client.resolveUaid(uaid);
    
  3. Display agent details:

    import { Logger } from '@hashgraphonline/standards-sdk';
    
    const logger = new Logger({ module: 'AgentResolver', level: 'info' });
    
    logger.info('Agent resolved', {
      name: agent.name,
      description: agent.description,
      protocols: agent.protocols,
      capabilities: agent.capabilities,
      endpoint: agent.endpoint,
    });
    

Response Structure

The resolved agent includes:

  • name - Agent display name
  • description - What the agent does
  • protocols - Supported protocols (hcs-10, a2a, mcp, etc.)
  • capabilities - Agent capabilities (chat, search, etc.)
  • endpoint - Connection endpoint URL
  • registry - Source registry
  • topicId - Hedera topic ID (for HCS agents)

Notes

  • UAID format: protocol://identifier/name
  • Common protocols: hcs10, erc8004, a2a
  • Returns 404 if agent not found

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
