Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install claude-api-common-mistakes

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 your Anthropic API calls and flags frequent mistakes: missing max_tokens, system prompt in the messages array, non-alternating messages, unchecked stop_reason, a new client per request, unhandled 529 errors or hardcoded model IDs. You get the fixes to apply.
