Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install code-property-graph-analysis

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent relies on a code property graph (AST, control flow, dependencies) built with Joern, and on CodeQL for interprocedural taint analysis. It is meant for deep analysis when everyday navigation is not enough. Joern requires Docker or the JVM, and CodeQL requires its CLI.
