prometheus-skill

prometheus-skill is a skill for Claude Code, Codex from kubiyabot/skill. It costs 0 tokens per session (908 once invoked), scanned A, original, Apache-2.0.

A skill for querying and monitoring Prometheus, a system that stores time-based measurements such as CPU usage and request counts.

In plain words
What is it for?
Use it to run PromQL queries, search time series and labels, check target health, inspect alerts and rules, and view runtime information.
Why use it?
It lets developers inspect metrics, alert rules, active alerts, monitored targets, and server status from the Prometheus HTTP API.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

prometheus-skill scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (src/skill.ts), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Prometheus Skill

Prometheus metrics querying and monitoring operations.

Overview

This skill provides comprehensive access to the Prometheus HTTP API for querying metrics, managing alerts, and monitoring system status.

Requirements

  • Prometheus server accessible via HTTP
  • Optional: Basic authentication credentials if enabled

Configuration

export SKILL_PROMETHEUS_URL=http://localhost:9090

Tools (15)

Query Tools

  • query - Execute instant PromQL query at a single point in time
  • query-range - Execute PromQL query over a time range with step interval
  • series - Find time series matching label selectors
  • labels - Get all label names in the database
  • label-values - Get all values for a specific label

Target & Rule Tools

  • targets - Get current scrape targets and their health status
  • rules - Get alerting and recording rules
  • alerts - Get currently firing alerts
  • metadata - Get metric metadata (type, help, unit)

Status Tools

  • status-config - Get current Prometheus configuration
  • status-flags - Get configured flag values
  • status-runtimeinfo - Get runtime information (memory, goroutines, etc.)
  • status-buildinfo - Get build information (version, revision, etc.)
  • status-tsdb - Get TSDB storage statistics
  • check-health - Check if Prometheus is healthy and ready

Example Usage

Query Current Metrics

Tool: query
Args: { "query": "up" }
Result: Shows which targets are up (1) or down (0)

Query CPU Usage Over Time

Tool: query-range
Args: {
  "query": "rate(node_cpu_seconds_total{mode=\"user\"}[5m])",
  "start": "2024-01-01T00:00:00Z",
  "end": "2024-01-01T01:00:00Z",
  "step": "1m"
}
Result: CPU usage rate over the specified time range

Find Series by Label

Tool: series
Args: { "match": "{job=\"prometheus\"}" }
Result: All time series for the prometheus job

Get Label Values

Tool: label-values
Args: { "label": "job" }
Result: ["prometheus", "node-exporter", "alertmanager", ...]

Files

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

prometheus-skill is a skill published in the GitHub repository kubiyabot/skill (19 stars, last pushed 8mo ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 908 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
