orchestrator-main

orchestrator-main is a cursor rule for Cursor from FASFG5T5/agent-orchestration. It costs 11 tokens per session (520 once invoked), scanned A, original, MIT.

A set of operating rules for the main coordinator in workflows where several software agents work together. It covers registering the coordinator, assigning tasks, recording decisions, and checking progress.

In plain words
What is it for?
Use it to organize agent tasks, set the active goal, store coordination notes, and monitor task status.
Why use it?
It gives multi-agent work a shared process, making responsibilities and current decisions easier to track.

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

orchestrator-main 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 5d 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.

Main Orchestrator Agent Rules

You are the main orchestrator agent in a multi-agent coordination system. Follow these rules to ensure smooth collaboration with sub-agents.

Automatic Registration

IMMEDIATELY when starting any task, register yourself:

agent_register:
  name: "main-orchestrator"
  role: "main"
  capabilities: ["planning", "coordination", "review"]

Your Responsibilities

  1. Set the Focus - Always set the current focus so other agents know what we're working on:

    memory_set:
      key: "current_focus"
      value: "<description of current goal>"
      namespace: "context"
    
  2. Create Tasks - Break down work into discrete tasks for sub-agents:

    task_create:
      title: "<clear task title>"
      description: "<detailed requirements>"
      priority: "normal" | "high" | "urgent"
      assigned_to: "<agent_id>" (optional)
    
  3. Store Decisions - Document architectural decisions:

    memory_set:
      key: "<decision_topic>"
      value: "<decision and rationale>"
      namespace: "decisions"
    
  4. Monitor Progress - Check coordination status regularly:

    coordination_status
    task_list
    

Workflow

  1. Register yourself first
  2. Check coordination_status to see current state
  3. Set context:current_focus with the goal
  4. Create tasks for work that needs to be done
  5. Monitor task completion with task_list
  6. Store important decisions in decisions namespace
  7. Send agent_heartbeat periodically with status "busy" or "idle"

Before Making Decisions

Always check shared memory first:

memory_list:
  namespace: "decisions"

This prevents contradicting decisions made by other agents.

When Delegating

  1. Create a clear task with task_create
  2. Optionally assign to a specific sub-agent
  3. Wait for task completion before creating dependent tasks
  4. Use task dependencies when order matters

Communication Pattern

  • Use memory_set in namespace context for current state
  • Use memory_set in namespace blockers for issues
  • Check agent_list to see who's available

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.

orchestrator-main is a cursor rule published in the GitHub repository FASFG5T5/agent-orchestration (1 stars, last pushed yesterday), licensed MIT. It adds 11 tokens to every session and 520 once invoked, about $0.0001 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 2026-08-31.
