systems-manager: Instructions file for Codex

AGENTS.md

systems-manager AGENTS.md is an instructions file for Codex, OpenCode from Knuckles-Team/systems-manager. It costs 5,070 tokens per session, scanned A, a copy of servicenow-api AGENTS.md, MIT.

Repository instructions for Knuckles-Team’s systems-manager project, documenting its Python stack, architecture, diagrams, and required commands.

In plain words
What is it for?
Use them when working on the project’s agent, MCP server, storage-health checks, credentials, skills, or related system-management components.
Why use it?
They give a coding agent the project’s expected structure and working rules, reducing mistakes when changing or running the code.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions CLAUDE.md; mentions subagents; mentions AGENTS.md.

This is Knuckles-Team/systems-manager's own configuration. It tells Codex and OpenCode how to work on systems-manager itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything systems-manager configures →

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

systems-manager AGENTS.md 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 3d 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.

Origin

This is a copy

86% identical to servicenow-api AGENTS.md — 103 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

AGENTS.md

Agent contract

Tool-neutral rules for any AI agent or human working in this repository. This block is maintained by the fleet standard; edit outside the markers.

  • Owner boundary: this repository owns one external system's calls, mappings and MCP tools (spec prefix CONN-SYSTEMS-MANAGER-); it depends on the connector SDK only. Feature routing across repositories: ecosystem boundaries.
  • Setup: run uv sync --locked, then pre-commit install. This installs the locked environment and git hooks; run pre-commit run --all-files for the gate command.
  • Gates: uvx pre-commit run --all-files must pass before you push. Do not bypass hooks to get green.
  • Commits: one logical change per commit with a Spec: <ID> trailer (or Spec: none (<reason>)), plus a Co-Authored-By: trailer naming the assisting agent. Stage explicit paths only; never git add -A or git add .. Use your own configured Git identity, never a tool or bot name.
  • Org rules: organization AGENTS.md.

Canonical guidance for any AI coding agent or human; tool-specific entry files (for example CLAUDE.md) only import this file. Edit this file.

Tech Stack & Architecture

  • Language/Version: Python 3.11–3.14
  • Core Libraries: scion-sdk, fastmcp, pydantic-ai, psutil, distro
  • Key principles: Functional patterns, Pydantic for data validation, asynchronous tool execution.
  • Architecture:
    • mcp_server.py: Main MCP server entry point and tool registration.
    • agent.py: Pydantic AI agent definition and logic.
    • storage_health.py: Physical-disk + BMC drive-fault health (CONCEPT:SM-OS.governance.sys-8/1.5) — SMART (incl. RAID megaraid passthrough), BMC/IPMI drive-slot faults, RAID PD state, correlated; runs over the manager seam (local or remote host).
    • bmc_credentials.py: consumes an exact runtime credential projection resolved by AgentConfig from an external secret reference.
    • skills/: Directory containing modular agent skills (if applicable).

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.
