lexq-cli: Instructions file for Codex

AGENTS.md

lexq-cli AGENTS.md is an instructions file for Codex, OpenCode from lexq-io/lexq-cli. It costs 2,237 tokens per session, scanned A, original, Apache-2.0.

An instruction guide for LexQ CLI, a command-line tool for managing business rules written as if-then policies. These policies evaluate facts and produce actions such as discounts, blocks, or notifications.

In plain words
What is it for?
Use it to manage policy groups and rules, run the LexQ command-line tool, or expose its commands as tools through an MCP server. The guide covers authentication, workflows, condition syntax, actions, and conflict handling.
Why use it?
It tells AI agents how to install, authenticate, and use LexQ commands without having to infer the command structure.

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

This is lexq-io/lexq-cli's own configuration. It tells Codex and OpenCode how to work on lexq-cli 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 lexq-cli 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

lexq-cli 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 yesterday.

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 — LexQ CLI Agent Guide

For AI Agents and AI-powered IDEs (Claude Code, Cursor, Windsurf, Cline, Gemini CLI, Copilot, and others).

What is this?

LexQ CLI (@lexq/cli, binary: lexq) manages a policy execution engine. Policies are business rules (if-then) that evaluate input facts and produce actions: change a number such as a discount, set a fact, or record a rejection.

The CLI also doubles as an MCP server — run lexq serve --mcp to expose the full command inventory as MCP tools to any MCP-compatible AI client.

This file tells you how to use the CLI as an AI agent.

Quick Start

# 1. Install
npm install -g @lexq/cli
# or: npx @lexq/cli

# 2. Authenticate
lexq auth login
# Enter API key when prompted

# 3. Verify
lexq auth whoami

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.
