## What it does

The skill kicks in when you ask to create or write a PromQL query, a metric expression, an alerting rule, a recording rule or a Prometheus dashboard panel. It splits the job into stages: first the monitoring goal (request rate, errors, latency, resource usage), then the metric type and available labels, then the time window and aggregation. Only after that does it generate the expression.

Four metric types are covered. For counters with a `_total` suffix it reaches for `rate()`, `irate()` or `increase()`; for histograms with `_bucket`, `_sum` and `_count` it uses `histogram_quantile()`; for gauges it applies aggregations like `avg_over_time()`. Name suffixes serve as the type hint, so keep your metric names as they actually sit in Prometheus.

Before any code appears, the skill prints a plain-English query plan and waits for your confirmation. If you already gave a threshold and a window in your first message, it treats them as pre-filled and skips the re-asking. One caveat: without metric names and labels from your setup, it falls back to common naming patterns, so it pays to have the service metric list handy.

Install runs through `npx skills add` for Claude, Codex, Cursor, Gemini CLI and OpenCode; GitHub Copilot uses `gh skill install`.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add akin-ozer/cc-devops-skills --skill promql-generator -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/promql-generator/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/promql-generator/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add akin-ozer/cc-devops-skills --skill promql-generator -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/promql-generator/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add akin-ozer/cc-devops-skills --skill promql-generator -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/promql-generator/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install akin-ozer/cc-devops-skills promql-generator
```

2. **Manually: put the files in place**
- File: `.github/skills/promql-generator/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add akin-ozer/cc-devops-skills --skill promql-generator -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/akin-ozer/cc-devops-skills --path devops-skills-plugin/skills/promql-generator
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/promql-generator/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add akin-ozer/cc-devops-skills --skill promql-generator -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/akin-ozer/cc-devops-skills/tree/HEAD/devops-skills-plugin/skills/promql-generator/SKILL.md

## When to use it
- build an error-rate expression for one service
- write an alerting rule for a P95 latency threshold
- compute a rate over a counter within a window
- lay out a Grafana panel for RED metrics
- turn a monitoring requirement into a PromQL expression

## Example prompts
- Create a PromQL query for the error rate of payment-service over 5 minutes
- Write an alerting rule for P95 latency above 500ms
- Generate a recording rule for request sums by endpoint

# PromQL Query Generator

## Overview

This skill provides a comprehensive, interactive workflow for generating production-ready PromQL queries with best practices built-in. Generate queries for monitoring dashboards, alerting rules, and ad-hoc analysis with an emphasis on user collaboration and planning before code generation.

## When to Use This Skill

Invoke this skill when:
- Creating new PromQL queries from scratch
- Building monitoring dashboards (Grafana, Prometheus UI, etc.)
- Implementing alerting rules for Prometheus Alertmanager
- Analyzing metrics for troubleshooting or capacity planning
- Converting monitoring requirements into PromQL expressions
- Learning PromQL or teaching others
- The user asks to "create", "generate", "build", or "write" PromQL queries
- Working with Prometheus metrics (counters, gauges, histograms, summaries)
- Implementing RED (Rate, Errors, Duration) or USE (Utilization, Saturation, Errors) metrics

## Interactive Query Planning Workflow

**CRITICAL**: This skill emphasizes **interactive planning** before query generation. Always engage the user in a collaborative planning process to ensure the generated query matches their exact intentions.

Follow this workflow when generating PromQL queries:

### Stage 1: Understand the Monitoring Goal

Start by understanding what the user wants to monitor or measure. Ask clarifying questions to gather requirements:

1. **Primary Goal**: What are you trying to monitor or measure?
   - Request rate (requests per second)
   - Error rate (percentage of failed requests)
   - Latency/duration (response times, percentiles)
   - Resource usage (CPU, memory, disk, network)
   - Availability/uptime
   - Queue depth, saturation, throughput
   - Custom business metrics

2. **Use Case**: What will this query be used for?
   - Dashboard visualization (Grafana, Prometheus UI)
   - Alerting rule (firing when threshold exceeded)
   - Ad-hoc troubleshooting/analysis
   - Recording rule (pre-computed aggregation)
   - Capacity planning or SLO tracking

3. **Context**: Any additional context?
   - Service/application name
   - Team or project
   - Priority level
   - Existing metrics or naming conventions
```
