Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install retell-voice-agent-errors

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 the reported error and applies the fix from six common cases: invalid key, badly formatted number, unresponsive agent, function call timeout, webhooks not received and voice quality issues. You get a likely cause and a precise action.
