Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install prometheus-cardinality-incident-triage

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 reads the TSDB status endpoints, finds the metrics and labels responsible, then proposes fixes that do not drop any label that makes a series unique. You get a diagnosis of active series and their causes.
