Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install api-schema-migration-safety

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 identifies the consumers, classifies the change and runs the expand-then-contract sequence, with recipes for Protobuf, SQL and HTTP. You get a reversible, verified migration.
