Argos — Security skill for Claude Code

Argos is an agent plugin, MCP server, and CLI for offensive security research. It keeps a durable map of what a target does, how its parts relate, what has been tested, and which conclusions still depend on unproven assumptions. Each real item has one canonical Markdown note. Typed links connect components, sinks, data, authority, state, tests, evidence, and findings.

The map helps an agent recover more than matching text. It can follow nearby relations, find paths between sinks, flag partial test coverage, show knowledge age, and suggest missing links for review. Every structural change remains explicit.

Canonical knowledge	Linked recovery	Blind-spot checks	Obsidian view
One current note per item. Replaced text is discarded.	Bounded subgraphs instead of full database dumps.	Partial path coverage, mixed evidence, old premises, and missing context.	Automatically refreshed Markdown notes, exact graph links, a compact index, and a Bases explorer.
