Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install dev-toolbar-safety-review

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 reviews changes to the dev toolbar folder and the PostHog client: environment guards, flag override cookies, telemetry event subscription and SSE streams. It flags when a growth-team review is required. You get a completed checklist and the points to fix.
