Why Claude skills creators switch to AgentVerif

You spent hours building a skill that clients actually pay for. Then someone copies it, tweaks it, or shares it for free — and your income disappears.

Buyers keep asking: “Is this skill safe and original?”
One verification badge ends the questions and builds instant trust.
The moment you deliver the skill, you lose control
Tamper detection + MCP auto-verify blocks modified versions before they run.
Copies kill your recurring revenue
Verified skills convert better, reduce refunds, and protect the income you already earn.

Your agent is one button away from being stolen.

Buyers resell. You don’t see a cent.

An unprotected agent ZIP can be forwarded, resold, or uploaded anywhere. Single-use licenses make your work non-transferable — cryptographically.

Unlimited copies from one purchase.

Without activation limits, one buyer becomes a thousand. Pro licenses let you set exactly how many times your agent can be activated.

No proof. No recourse.

If your agent gets stolen and redistributed, you have nothing. A revocable agentverif license gives you proof of issue, proof of abuse, and the ability to kill the license instantly.

It takes 30 seconds

One command. A license ID. Verification everywhere buyers run your skill.

Run one command to sign your skill

CLI or GitHub Action. Your ZIP is scanned against the OWASP LLM Top 10, then signed in seconds.

agentverif-sign sign

Get a clean badge + License ID

A unique License ID is generated, a cryptographic hash registered, and SIGNATURE.json injected into your ZIP.

Buyers see VERIFIED ✓ Safe to run inside Claude

Buyers verify via CLI, MCP, or directly inside Claude. If your skill leaks, revoke in one command — it stops everywhere instantly.

CLI quickstart

As a seller

agentverif-sign sign ./agent.zip # Signed successfully # License: AC-84F2-91AB # Tier: indie

As a buyer

agentverif-sign verify ./agent.zip # VERIFIED # License: AC-84F2-91AB # Verify: verify.agentverif.com/…

Output is JSON-compatible for CI/CD pipelines, LLM tool calls, and MCP integrations (agentverif-sign verify --json).

The window to set the standard is open. Not for long.

The AI agent marketplace is forming now. Certified agents will win by default.

Your competitor is already protecting their skills.

Verified skills convert better and command higher prices. First-mover advantage in trust is real.

One copied skill kills recurring revenue.

A single redistribution wipes out months of income. Tamper detection proves you shipped the original.

Enterprise teams need proof before deploying.

Compliance teams require audit trails. If you can’t prove your skill is authentic and unmodified, you don’t get deployed.
