A plugin bundle containing shared skills, a web-research agent, and safeguards around Git and plan execution. The supplied description does not explain the individual skills or safeguards in more detail.

It is for projects that want Nico's shared skills, web research, and Git or plan-run guard hooks. More specific jobs cannot be confirmed from the supplied description.

It groups several agent-related tools in one plugin, but the available information is too limited to describe their exact behaviour or limits.

nico — Plugin for Claude Code by nicograef/handbook

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/nicograef/handbook

Made for: Claude Code.

Security

Grade A, and why

nico 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 25d 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. 10 skills, 1 agent, 4 hooks travel with it, and installing the plugin installs all of them — 561 tokens a session between them. Each is measured on its own page, and each can be installed alone.

Files

What ships with it

1 file beside plugin.json in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
