Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install constant-time-crypto-code-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 runs the analysis tool on the files you name, selects the language rules, then flags branches and operations that depend on a secret. You get a findings report, optionally as JSON for continuous integration.
