Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install legacy-code-specification-extraction

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 analyses existing code to map its dependencies, generate API documentation from the source and identify undocumented business logic. It then produces an architecture specification based on the implementation.
