Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install clickhouse-postgres-root-cause

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 queries the Prometheus endpoint and the Slow Query Patterns API, sorts the problem (full scan, hot loop, write congestion), then writes an evidence-based diagnosis. It recommends the fix and does not apply it.
