What it does, in the publisher's words

Write, validate, and optimize PromQL for Prometheus / Grafana Mimir / Grafana Cloud Metrics. Covers `rate` vs `irate` vs `increase`, label matchers and regex, `sum / avg / topk / by / without` aggregation, classic + native `histogram_quantile`, ratios with divide-by-zero guards, `absent` / `changes` for staleness, time offsets and `predict_linear`, recording-rule naming, SLO + burn-rate math, and a...

The description field of the SKILL.md. The agent reads only this at startup and decides from it when to load the full skill.

Install PromQL

The skills CLI copies the skill into the folder of each agent you pick (Claude Code, Codex, Cursor, Copilot, Gemini CLI, OpenCode, Windsurf...). Add -g for all projects. Needs Node.js 22.20+. docs

npx skills add grafana/skills --skill promql

This repo is a plugin marketplace. Inside Claude Code, add it and install the plugin that holds the skill (grafana-core, grafana-cloud, grafana-lgtm, grafana-plugins...), or copy only this skill into ~/.claude/skills. docs

/plugin marketplace add grafana/skills
/plugin install <plugin>@grafana-skills

# or only this skill:
npx skills add grafana/skills --skill promql -a claude-code

Download the skill folder, zip it, then Customize > Skills > + > Create skill > Upload a skill. Code execution must be on (Settings > Capabilities). docs

git clone --depth 1 https://github.com/grafana/skills.git /tmp/promql-src
cp -r /tmp/promql-src/skills/grafana-core/promql ./promql
zip -r promql.zip promql

Codex reads skills from .agents/skills in the repo or ~/.agents/skills. Type $ in Codex to use one. docs

npx skills add grafana/skills --skill promql -a codex

gh skill (GitHub CLI 2.90+, preview) installs it for Copilot in VS Code, the CLI and the cloud agent. Copilot also reads .github/skills and ~/.copilot/skills. docs

gh skill install grafana/skills promql

Cursor reads .cursor/skills, .agents/skills and ~/.cursor/skills (and .claude/skills). It does not install loose skills from a GitHub URL, so copy it in. docs

npx skills add grafana/skills --skill promql -a cursor

Installs from the GitHub repo; --path picks this skill out of the repo. Default scope is user (all projects). docs

gemini skills install https://github.com/grafana/skills.git --path skills/grafana-core/promql

OpenCode reads .opencode/skills, ~/.config/opencode/skills and the Claude and .agents folders. docs

npx skills add grafana/skills --skill promql -a opencode

Windsurf (now Devin Desktop) reads .devin/skills, .windsurf/skills and ~/.codeium/windsurf/skills. docs

npx skills add grafana/skills --skill promql -a windsurf

Works with

Claude Code, Claude.ai and Claude Desktop, Codex, GitHub Copilot, Cursor, Gemini CLI, OpenCode, Windsurf and other agents that read the open Agent Skills format.
