atlas

atlas is a plugin for Claude Code from shuxueshuxue/Spexcode. Its manifest loads nothing; the 1 skill it bundles cost 80 tokens per session together, scanned A, original, MIT.

A plugin that chooses important specification nodes in a repository and creates diagrams for them with SpexCode. A specification describes how a system is intended to work; the plugin checks each diagram until it passes.

In plain words
What is it for?
Creating a visual atlas of selected specification or architecture nodes.
Why use it?
It makes selected parts of a repository's written specification easier to understand visually. The details do not say which diagram types or checks are supported.

Security

Grade A, and why

atlas 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 today.

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. 1 skill travel with it, and installing the plugin installs all of them — 80 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.
