A read-only code-search and investigation plugin with one stable interface for meaning-based and structural searches. It can trace callers, callees, and affected code, and can dispatch a deeper investigation agent.

Use it to search code, follow relationships between functions, inspect blast radius, or start a deeper codebase investigation.

It gives coding agents a consistent way to navigate unfamiliar code and assess the likely impact of a change without editing the project.

Install

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.

Clone the repo

git clone --depth 1 https://github.com/MadAppGang/magus

Made for: Claude Code.

Security

Grade A, and why

code-search 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.

Contents

What it installs

The manifest is a name and a version. 4 skills, 3 commands, 1 agent travel with it, and installing the plugin installs all of them — 542 tokens a session between them. Each is measured on its own page, and each can be installed alone.

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.
