What is lis186-SourceAtlas?

A plugin marketplace listing for SourceAtlas, an AI-assisted codebase-understanding tool. It is described as helping explain design patterns, trace code flows, and assess the effect of changes.

Use it to make the SourceAtlas plugin available through a marketplace. Its listed jobs include understanding unfamiliar code, tracing execution paths, and analysing change impact.

It gives a package manager a description, version, owner, and source location for the SourceAtlas plugin. The input does not explain how the plugin performs its analysis.

Security

Grade A, and why

lis186-SourceAtlas 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 2d 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 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.
