agent-agentic-os

agent-agentic-os is a plugin for Claude Code from richfrem/agent-plugins-skills. Its manifest loads nothing; the 14 skills, 2 agents, 3 hooks it bundles cost 2,622 tokens per session together, scanned A, original, MIT.

A plugin that adds structured memory, project setup, improvement cycles, checks for proposed changes, and coordination between multiple coding agents. It is designed for long-running development work where agents need to retain context and learn from past runs.

In plain words
What is it for?
Use it to manage agent memory, coordinate agents, run evaluations, handle sessions, improve instructions over time, and set up an Agentic OS around a project.
Why use it?
It organizes information and feedback that would otherwise be scattered across sessions and tools. It also provides a process for checking whether changes actually improve results.

Security

Grade A, and why

agent-agentic-os 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 26d 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.

What it installs

The manifest is a name and a version. 14 skills, 2 agents, 3 hooks travel with it, and installing the plugin installs all of them — 2,622 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.
