fan-manager: Instructions file for Codex

AGENTS.md

fan-manager AGENTS.md is an instructions file for Codex, OpenCode from Knuckles-Team/fan-manager. It costs 4,362 tokens per session, scanned A, original, MIT.

Project instructions for Fan Manager, a small Python tool for controlling Dell PowerEdge server fans and checking temperatures. It uses IPMI, a server-management interface, and local sensor tools to communicate with hardware.

In plain words
What is it for?
They are for working on fan and temperature control, server power and sensor operations, BMC management, asynchronous tools, and tests or commands in the repository.
Why use it?
They define the project's architecture, supported control paths, credential handling, and exact commands, helping changes fit the tool's intentionally simple design.

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

This is Knuckles-Team/fan-manager's own configuration. It tells Codex and OpenCode how to work on fan-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 fan-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

fan-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 today.

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.

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-FAN-MANAGER-); it depends on the connector SDK only. Feature routing across repositories: ecosystem boundaries.
  • Setup: run scripts/bootstrap.sh. It is idempotent and non-interactive: it pins uv and Python, syncs the locked environment, installs the git hooks and prints 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+
  • Core Libraries: agent-connector-sdk, fastmcp (via agent-connector-sdk[mcp]), pydantic-ai
  • Domain: Dell PowerEdge / IPMI 2.0 control via ipmitool + lm-sensors. Thermal (fan/temperature) runs local with no creds; the IPMI/BMC wrapper (CONCEPT:FM-OS.governance.power-chassis..008: power, sensors, SEL, SoL, BMC LAN/user config, raw) runs in-band (local /dev/ipmi0) or out-of-band over LAN (-I lanplus -H -U -P, creds from OpenBao apps/idrac).
  • Key principles: Functional patterns, Pydantic for data validation, asynchronous tool execution, action-routed MCP tools.

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.
