Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install pydantic-ai-error-debugging

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 error from the message or the code, shows the faulty pattern and the corrected version. It covers RunContext in tool_plain and tools missing RunContext. You get the corrected code.
