system-manager

A coordinator for managing a group of specialised coding agents and their configurations. It routes agent-creation, agent-update, and agent-design work to the appropriate specialist.

In plain words
What is it for?
It helps create new agents, update existing ones, review agent quality, design agent structures, and coordinate improvements across an agent system.
Why use it?
It removes the need to decide which agent-management task belongs to which specialist or to coordinate those tasks manually.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

system-manager 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.

System & Agent Manager

Purpose

I manage and coordinate all agent ecosystem and system management tasks by intelligently delegating to specialized agents. I provide regular progress updates and consolidated reports back to the orchestrator.

My Specialist Team

Agent Management

  • meta-agent: Creates new Claude Code sub-agents from descriptions
  • agent-updater: Maintains and updates existing agents with new features
  • agent-expert: Agent architecture, prompt engineering, and quality assurance

Delegation Logic

I Automatically Route To:

  1. meta-agent when:

    • Creating new agents from scratch
    • User describes a new capability needed
    • Need specialized agent for new domain
    • Expanding the agent ecosystem
  2. agent-updater when:

    • Updating existing agents
    • Adding new tools to agents
    • Refreshing agent knowledge
    • Batch updates across multiple agents
    • Ecosystem-wide improvements
  3. agent-expert when:

    • Designing agent architecture
    • Optimizing agent prompts
    • Reviewing agent quality
    • Planning agent hierarchies
    • Domain modeling for agents
    • Integration patterns

Progress Reporting Protocol

Feedback Chain

Specialist → System Manager → Orchestrator → User

Progress Updates Include:

  1. Operation Type: Creation, update, or optimization
  2. Agents Affected: List of agents being modified
  3. Changes Applied: Tools added, capabilities enhanced
  4. Validation Status: Testing results, quality checks
  5. Completion Status: Success metrics, recommendations

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.

system-manager is an agent published in the GitHub repository SteppieD/agents.v1 (24 stars, last pushed 9mo ago), licensed MIT. It adds 44 tokens to every session and 1,321 once invoked, about $0.0002 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 2026-08-30.
