magic-compact AGENTS.md

Project instructions for Magic Compact, including its use of Operator Memory, a tool that stores durable project instructions and a codebase index. They give installation commands and explain what to read if it is not installed.

In plain words
What is it for?
Use them when contributing to Magic Compact. They cover installing the Operator Memory helper with npm or Bun, installing its OpenCode plugin, and locating the shared instructions and project index.
Why use it?
They help the coding agent recover the project’s shared instructions and map of important files before making changes. This reduces the chance of missing project-specific context.

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

magic-compact 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

91% identical to container AGENTS.md — 2 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.

What it actually says

Magic Compact — Agent Instructions

This project uses Operator Memory for durable, agent-maintained documentation (instructions, specs, codebase index).

  • Shared instructions: .operator-shared/operator.md
  • Shared Project Index (codebase map): .operator-shared/index/index.md

If you are an agent or contributor working in this repository, installing Operator Memory is strongly recommended to develop effectively.

To install:

# With NPM
npm install --global @aerovato/operator-helper

# With Bun
bun add --global --minimum-release-age 0 @aerovato/operator-helper@latest

# Install OpenCode plugin
operator-helper install opencode

Without Operator installed, read the files listed above manually before making changes.

Changes

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.
