Bynn Agent Skills

Official Agent Skills for Bynn, ZOREAL, Agemin, and Detector24. They teach any coding agent how to integrate document fraud detection for manipulated, fake and AI-generated PDF and image documents, plus identity verification, proof-of-human sign-in and meetings, age verification, and content detection, including the parts that are easy to get subtly and dangerously wrong. The onboarding below also installs the DecisionNode skill from its own repository, decision-node-skills.

Works with Claude Code, Cursor, Codex, Copilot, Gemini CLI, OpenCode, Windsurf, Zed, and every other agent the skills CLI supports.

Onboard an agent in one shot

Paste this line into any coding agent and it installs the Bynn, ZOREAL, DecisionNode, Agemin and Detector24 skills plus the MCP servers itself, following agent-setup.md:

Set up Bynn, ZOREAL, DecisionNode, Agemin and Detector24 for me: fetch https://bynn.com/agent-setup.md and follow it.

It covers Claude Code, Cursor, VS Code, Windsurf, Zed, Claude Desktop, ChatGPT, and headless or CI setups, and tells the agent what to verify before it reports success.

https://bynn.com/agent-setup.md serves this repository's agent-setup.md as it is; its source is https://github.com/Bynn-Intelligence/skills/blob/main/agent-setup.md.

Install

Any agent:

npx skills add Bynn-Intelligence/skills

The installer shows a picker grouped by product (Bynn, ZOREAL, Agemin, Detector24), so you can toggle a whole product with one keypress on its group header. Press a to select everything. Nothing is pre-selected, which is the CLI's behaviour and not configurable per repository.

To skip the picker entirely:

# every skill, every detected agent, no promptsnpx skills add Bynn-Intelligence/skills --all
# every skill, but choose the agents yourselfnpx skills add Bynn-Intelligence/skills --skill '*'
# just one product's skillsnpx skills add Bynn-Intelligence/skills --skill bynn --skill bynn-mcp --skill bynn-kyc-sessions

Running inside a coding agent skips the picker on its own and installs everything.

Claude Code, with the bundled MCP server:

/plugin marketplace add Bynn-Intelligence/skills/plugin install bynn@bynn/plugin install zoreal@bynn

DecisionNode is installed from its own marketplace:

/plugin marketplace add Bynn-Intelligence/decision-node-skills/plugin install decisionnode@decisionnode

What is in here

bynn

The identity platform. Start with the bynn skill: it routes to the rest.

zoreal

ZOREAL, the trust layer that proves a real human is present behind a digital interaction.

ZOREAL Verify, which includes PDFChecker, runs its checks through the Bynn API today, so its integration lives in bynn-document-fraud and bynn-kyc-sessions.

agemin

Biometric age verification for websites and apps.

detector24

Detection models for image, video, audio, and text.

Credentials

Nothing here ships a credential. Each skill says which key it needs and where to get it.

Connect the MCP server

Installing skills does not connect the Bynn MCP server: npx skills add copies skill files only. Connect it separately to get the Bynn tools.

claude mcp add --transport http bynn https://mcp.bynn.com

Then run /mcp and sign in. The Claude Code plugin registers this URL for you, but it stays inert until that sign-in completes. For headless use, pass a token instead:

claude mcp add --transport http bynn https://mcp.bynn.com \  --header "Authorization: Bearer $BYNN_API_TOKEN"

The endpoint is the root path. Appending /mcp returns a 404.

The DecisionNode docs server needs no key or sign-in, and the decisionnode plugin registers it for you:

claude mcp add --transport http decisionnode-docs https://decisionnode.com/mcp``` Other clients, includingClaude Desktop, ChatGPT, Cursor, VS Code, Windsurf, and Zed, are covered in the`bynn-mcp` skill.
## Two rules worth reading before you build
**Never preprocess media.** Do not resize, crop, re-encode, or strip metadata beforesubmitting an image, video, or document for fraud, tampering, or AI-generation analysis.Those detectors read artifacts that live in the exact bytes of the original file, andprocessing destroys them silently. The result comes back looking clean.
**The browser is never the verdict.** SDK callbacks run on the visitor's own machine.Confirm every result server side before unlocking anything.
