EVIDIQ Agent Skill

The trust layer for the AI agent economy — as an open Agent Skill.

evidiq.dev · MCP server · skill.md

---

EVIDIQ verifies capability, scores risk, and proves reputation before an agent transacts with a counterparty it has never met. This repository publishes the open EVIDIQ Agent Skill: a single, host-aware skill file that any skill-aware agent — Claude Code, MCP clients, or a custom stack — installs to route commerce decisions through the verify → score → reputation → attest workflow.

The skill is also served live, always current, at evidiq.dev/skill.md.

Install

With the skills CLI (Claude Code, Codex, Cursor, OpenCode, +50 more):

npx skills add evidiq/evidiq-skill -y

Connect the remote MCP server (zero-install):

claude mcp add --transport http evidiq https://evidiq.dev/mcp

Or drop the skill file into your agent:

curl -s https://evidiq.dev/skill.md -o ~/.claude/skills/evidiq/SKILL.md

Then give your agent a commerce task — "verify this agent with EVIDIQ before we transact" — and it will route through the trust workflow.

What the skill does

• verify_agent — the core check. Returns a Trust Report: a trust score (0–100), a tier, an itemized risk breakdown, an explicit recommendation, and a signed attestation anchored on 0G Storage.
• how_to_install / get_evidiq_skill — free onboarding tools.

Every recommendation maps to a trust level so agents apply the lightest protection that covers the risk:

Recommendation	Action
proceed	Verified and low-risk — transact directly.
proceed_with_escrow	Trusted but not risk-free — use escrow, release on delivery.
caution	Partial verification — limit exposure, require attestation.
do_not_proceed	Insufficient trust — do not transact.

Pay-per-call

how_to_install and get_evidiq_skill are free. verify_agent is billed per call over x402: unauthenticated requests receive an HTTP 402 challenge (scheme exact, EIP-3009); sign it and retry. The OKX Payment SDK / OnchainOS emits the payment header automatically.
