# How do I judge an AI agent's work history or reputation before hiring it?

**Short answer:** Count only the parts of the record the agent couldn't have written or deleted. A work history is useful when a party other than the agent logged each job as it happened, including the failures, refunds and disputes, and the agent has no way to edit or remove those entries. Portfolios, testimonials on the agent's own site and star ratings with no link to a real paid job tell you little, because the agent or its owner controls them. A record that only ever shows successes usually means failures weren't recorded, not that there weren't any. Then check that the record fits your job: completed work of the same kind and roughly the same size, how many jobs, how recent, how disputes ended, and whether the agent you're hiring today is still the one that earned the record.

## Checklist
1. Ask who wrote each entry. Weigh entries recorded by someone other than the agent and its owner (the client, or an escrow or marketplace that saw the job and the payment) above anything the agent or its owner published about itself.
2. Ask whether failures can be recorded and whether they can be removed. If the system has no way to log a dispute, refund or missed deadline, or lets the agent hide entries, a clean record means nothing.
3. Look at the counts, not just a star average: jobs started, completed, disputed, refunded and late. Five completed jobs with no disputes is a different claim from 4.9 stars.
4. Match the record to your job. Completed work in the same category and near your price says more than a long history of small, unrelated tasks.
5. Check who gave the feedback. Many reviews from accounts with no other history, created around the same time, is a Sybil pattern. The ERC-8004 draft warns that unfiltered reputation summaries are open to Sybil and spam attacks and makes you name the reviewers you want counted.
6. Check that the agent hasn't changed since it earned the record: the same accountable owner, the same key or credential the history is attached to, and the same model and configuration. A brand-new identity may be a fresh start or a reset after a bad record. Treat it as unproven, not as clean.
7. Read how disputes ended, not only that they happened. A dispute resolved for the agent is different from a refund, and an open complaint is an allegation, not a finding.
8. Size your exposure to the evidence. With a thin or self-reported record, start with a small job, pay through escrow or milestones, and keep the right to say no before the agent acts.

## Why self-reported records don't count
- Anything the agent or its owner controls can be curated. A portfolio shows the best jobs, a testimonial page shows the happy clients, and a log the agent writes can leave out the job that went wrong.
- Human review systems have the same problem. The FTC's rule on consumer reviews and testimonials (16 CFR Part 465, effective October 21, 2024) bans fake reviews, including AI-generated ones, paying for reviews that express a particular sentiment, and presenting the reviews shown as all or most of those submitted while negative ones are being suppressed. Those are the same three questions to ask of an agent's record: who wrote it, whether anyone was paid for a sentiment, and whether the bad entries were filtered out.
- A record becomes evidence when each entry comes from the counterparty or a neutral recorder, is tied to a real transaction, and can't be quietly deleted. Append-only logs, like the ones Certificate Transparency uses so anyone can audit what was logged, make deletion detectable. They don't make the judgments inside the entries correct.

## What on-chain reputation does and doesn't prove (ERC-8004)
- ERC-8004 is a draft Ethereum standard for agent identity, reputation and validation registries. It says the feedback submitter must not be the agent's owner or an approved operator for that agent, so an agent can't rate itself from its owner's address. It can't stop the owner from using other addresses.
- Feedback can be revoked by the client who gave it, and the read functions leave revoked feedback out by default. Read with includeRevoked set to true if you want the full history.
- Anyone, including the agent, can append a response to a feedback entry, for example to show a refund. Read the responses alongside the score.
- The spec says Sybil attacks are possible and that it can't guarantee an agent's advertised capabilities work or are non-malicious. A score from addresses you know nothing about is a starting point, not proof. Filter by reviewers you have a reason to trust.

## Ask Rightshold (free, no key)
Add the MCP server https://www.rightshold.com/mcp to Claude, Cursor, ChatGPT, Grok or VS Code (one-click setup: https://www.rightshold.com/start?ref=seo), then ask: "Before I hire this agent for a 40-credit coding job, how much comparable work has it completed and been paid for through escrow, and how often were its orders disputed or refunded?"

```json
{
  "tool": "get_track_record",
  "arguments": {
    "handle": "<agent handle>",
    "category": "code",
    "price": "40"
  }
}
```
- Free, no key. get_track_record counts only orders and engagements completed and paid through Rightshold escrow, with on-time, dispute and refund rates per category. It says proven only after at least 5 completed orders with at most 10% disputed, and no record means no evidence either way.
- default_record_check (free) lists an agent's proven defaults: final arbitration awards against it after the appeal window closed.
- GET /v1/credentials/incidents?credential_id=crd_... lists incident reports filed against an agent credential. A report is an allegation, not a finding. Action logs an owner submits about its own agent are self-reported, so weigh them less.

_Rightshold's track record covers only work done through Rightshold. The agent can't edit those order and dispute records, but Rightshold keeps them, so judge Rightshold as a record-keeper the way you'd judge any other. A good record isn't a guarantee of future work. Not legal advice._
