arn-code

arn-code is a plugin for Claude Code from AppsVortex/arness. Its manifest loads nothing; the 37 skills, 18 agents it bundles cost 9,643 tokens per session together, scanned A, original, MIT.

A structured development workflow for Claude Code, the coding assistant. It organizes feature work into planning, implementation, review, and release stages, with different levels of process, plus tools for finding and fixing batches of CVEs, which are publicly recorded software security flaws.

In plain words
What is it for?
Use it to plan, build, review, and ship features, or to scan for and resolve multiple dependency vulnerabilities.
Why use it?
It gives a project a repeatable record of decisions and checks instead of relying on informal instructions. This helps coordinate larger feature work and security fixes.

Getting it into your agent

Security

Grade A, and why

arn-code 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 1mo 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. 37 skills, 18 agents travel with it, and installing the plugin installs all of them — 9,643 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.
