arsenal-core

arsenal-core is a plugin for Claude Code from KratosAR/claude-code-arsenal. Its manifest loads nothing; the 43 skills, 15 agents it bundles cost 2,364 tokens per session together, scanned A, original, MIT.

A collection of development workflow tools and agents covering test-driven development, debugging, planning, architecture, security review, and MCP patterns. Test-driven development means writing tests to guide the code before or alongside implementation.

In plain words
What is it for?
Use it for planning work, resolving build errors, reviewing code and databases, improving documentation, running end-to-end tests, checking security, and guiding test-driven development.
Why use it?
It brings several common engineering checks and specialist roles into one add-on, reducing the need to assemble those workflows separately.

Security

Grade A, and why

arsenal-core 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. 43 skills, 15 agents travel with it, and installing the plugin installs all of them — 2,364 tokens a session between them. Each is measured on its own page, and each can be installed alone.

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.
