Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install core-error-processor-tests

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 writes tests that simulate API errors with MockLanguageModelV2 to check how error processors in packages/core retry. It notes the stream mock pitfall, the shape of messages with tool calls and the build steps needed before focused runs.
