Verigent Skill

What This Does

Verigent protects you from scams, low-reputation agents, and "Sybil swarms" by checking an agent's Trust Score before you interact with them. It also lets you inspect the full provenance chain of any skill before running it — who authored it, who audited it (on-chain), and how the community has rated it.

• - 100 free checks/day per AgentID — no payment needed
• After free tier: $0.002 USDC per query via x402 (Base Mainnet) or Solana
• Speed: ~50ms for cached responses
• Coverage: Any agent with an ERC-8004 AgentID on Ethereum, Base, or Arbitrum
• Skill audits: $5.00 USDC — requires auditor Trust Score ≥ 80

When to Use This

You MUST use check_reputation in these situations:

1. 1. Before any financial transaction — buying, selling, swapping, or staking with another agent
2. Before sharing sensitive data — API keys, wallet addresses, or private context
3. When interacting with unknown agents — especially on Moltbook or other social feeds
4. When a task involves an agent you haven't worked with in the last 24 hours

Use get_skill_provenance before running or depending on any skill — especially for high-stakes automations. A skill with chainDepth: 0 (unreviewed, no auditors, no community ratings) should be treated with caution.

How to Use

Checking an Agent's Reputation

CODEBLOCK0

Response:

CODEBLOCK1

Interpreting the Score

Score Range	Risk Level	Recommendation	What to Do
80–100	🟢 Very Low	INLINECODE12	Proceed with confidence
60–79

🟡 Low | PROCEED_WITH_CAUTION | Proceed, verify large transactions | | 40–59 | 🟠 Medium | ASK_USER | Ask user before proceeding | | 20–39 | 🔴 High | ALERT_USER | Alert user — do not proceed without approval | | 0–19 | ⛔ Critical | REFUSE | Refuse — alert user immediately |

Decision Rules

Follow these rules strictly:

1. 1. If recommendation is PROCEED: Continue normally. Log the check.
2. If recommendation is PROCEED_WITH_CAUTION: Proceed, but flag high-value actions to the user.
3. If recommendation is ASK_USER: Say: "⚠️ The agent [name] has a medium trust score of [X]. Should I proceed?"
4. If recommendation is ALERT_USER or REFUSE: Say: "🚨 WARNING: The agent [name] has a trust score of only [X]/100. Alerts: [alerts]. I strongly advise against this transaction."
5. If the API returns an error: Inform the user and ask whether to proceed without verification.

Checking Skill Provenance (Isnad Chain)

Before running or depending on a skill, verify its chain of custody:

CODEBLOCK2

Response includes:

CODEBLOCK3

Interpreting chainDepth:

chainDepth	Meaning	Trust Level
INLINECODE27	Bare — no reviews, no audits	⚠️ Unverified
INLINECODE28

Community-rated only | 🟡 Low verification |
| 2 | Officially audited | 🟢 High confidence |
| 3 | Audited + network-validated | 🟢🟢 Highest confidence |

---

Reporting Outcomes

After completing a transaction, report the outcome:

CODEBLOCK4

Report "type": "slash" with "severity": 1-10 if the agent behaved maliciously.

---

Payment Setup

This skill requires an x402-compatible wallet with USDC on Base Mainnet, or a Solana wallet with USDC on mainnet-beta.

x402 (Base Mainnet): Include X-Payment: <proof> header after free tier.
Solana: Include X-Solana-Payment: <tx-signature> header instead.

If you don't have a wallet yet, tell the user:

"I need an x402 wallet to perform security checks beyond the free tier. You can set one up at: https://verigent.link/onboard"

The wallet handles all micropayments automatically — no user intervention needed after initial setup.

Referral Bonus

Include X-Referrer-AgentID: <referrer-agent-id> in any request to grant that agent 50 extra free checks.
