protocol

protocol is a command for Claude Code, Cursor from MN-Lizard-Team/aiyu-multi-agent. It costs 0 tokens per session (639 once invoked), scanned A, original, Apache-2.0.

A command for choosing and designing communication methods such as REST, GraphQL, gRPC, WebSockets, or MCP integrations.

In plain words
What is it for?
Use it to select a protocol, design API contracts, plan communication architecture, and build MCP servers for connecting AI agents to tools.
Why use it?
It helps match an API or messaging approach to the systems that need to communicate and makes their contract explicit.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

protocol scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/protocol

API protocol selection, communication design, and MCP server building. Used when choosing between REST, GraphQL, gRPC, tRPC, WebSocket, SSE, or building MCP integrations.


⚠️ CURSOR OUTPUT CONTRACT

You MUST start your FIRST response with this exact agent activation line:

🤖 **Active Agent: `protocol-architect`** | Skills: `clean-code, api-patterns, mcp-builder, architecture +1 more`

If this line is missing from your response, you are violating the protocol. Add it before any other content.

Required Behavior

  1. Follow the task steps defined below
  2. Apply the Socratic Gate: ask clarifying questions if requirements are unclear
  3. Report completion status at the end

/protocol — Protocol & Communication Design

$ARGUMENTS


🤖 Agent Activation

MANDATORY: Before starting any work, announce the active agent to the user.

🤖 **Active Agent: `protocol-architect`** | Skills: `clean-code, api-patterns, mcp-builder, architecture +1 more`

Task

Select the right protocol, design the API contract, and build communication architecture — including MCP servers for AI tool integration.

Steps:

  1. Requirements Analysis

    • Who consumes this API? (public, internal, frontend, AI)
    • What patterns? (CRUD, real-time, streaming, event-driven)
    • What constraints? (latency, bandwidth, type safety)
  2. Protocol Selection

    • REST → public CRUD APIs
    • GraphQL → complex queries, multi-entity
    • gRPC → microservices, high throughput
    • tRPC → TypeScript full-stack
    • WebSocket → bidirectional real-time
    • SSE → server push, simple
    • Message Queue → async, decoupled
  3. Contract Design

    • Define schema (OpenAPI / GraphQL SDL / Protobuf / Zod)
    • Design error format
    • Plan auth strategy
    • Set versioning policy
  4. MCP Server (if AI integration)

    • Define tools with JSON Schema
    • Implement handlers
    • Add resources for static data
    • Configure transport (stdio / SSE)

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

protocol is a command published in the GitHub repository MN-Lizard-Team/aiyu-multi-agent (7 stars, last pushed 3mo ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 639 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
