protocol-orchestrator

protocol-orchestrator is a cursor rule for Cursor from MN-Lizard-Team/aiyu-multi-agent. It costs 85 tokens per session (1,355 once invoked), scanned A, original, Apache-2.0.

A coordinator for designing, building, securing, and deploying APIs across several specialised agents. It is intended for complete API lifecycles, microservice networks, and systems using multiple communication methods.

In plain words
What is it for?
Use it to manage end-to-end API projects, coordinate microservice integrations, standardise APIs, or plan migrations between communication protocols.
Why use it?
It reduces the coordination work involved when API architecture, implementation, security, and deployment must be handled together.

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-orchestrator 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 2d 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.

Protocol Orchestrator

Core Philosophy

  • Karpathy Principles: Think before coding, simplicity first, surgical changes, goal-driven execution

"A protocol is not just a technical choice. It is a contract that shapes how teams collaborate, how systems evolve, and how users experience your product."

When to Activate

  • Full API lifecycle design (from selection to deployment)
  • Microservice mesh with multiple protocols
  • API governance and standardization across teams
  • Migration between protocols (e.g., REST → gRPC)
  • Multi-protocol integration (REST public + gRPC internal + WebSocket real-time)
  • MCP ecosystem design (multiple MCP servers coordination)

Orchestration Patterns

Pattern A: Greenfield API Design

1. protocol-orchestrator → Gather requirements, define constraints
2. protocol-architect     → Select protocol, design contract
3. security-auditor       → Review contract for security gaps
4. backend-specialist     → Implement server-side
5. frontend-specialist    → Implement client-side
6. devops-engineer        → Deploy + monitor + rate limit
7. protocol-orchestrator  → Validate end-to-end, publish docs

Pattern B: Protocol Migration

1. protocol-orchestrator  → Assess current state, define migration scope
2. protocol-architect     → Design target protocol + migration path
3. code-archaeologist     → Analyze existing API consumers
4. backend-specialist     → Implement adapter/bridge layer
5. test-engineer          → Contract tests + backward compatibility
6. devops-engineer        → Canary deployment + traffic shifting
7. protocol-orchestrator  → Monitor metrics, complete cutover

What this file has done since we first saw it

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-orchestrator is a cursor rule published in the GitHub repository MN-Lizard-Team/aiyu-multi-agent (7 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 85 tokens to every session and 1,355 once invoked, about $0.0004 per session on Opus 5. 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.
