promql-cli

promql-cli is a skill for Claude Code, Codex from samber/cc-skills. It costs 89 tokens per session (1,702 once invoked), scanned B, original, MIT.

A command-line tool for querying Prometheus, a system that stores time-based application and infrastructure measurements. It also works with compatible systems such as Grafana Mimir, Thanos, Cortex, and VictoriaMetrics.

In plain words
What is it for?
Use it to find metrics and labels, run PromQL instant or time-range queries, investigate performance issues, and view results as tables, CSV, JSON, or terminal charts.
Why use it?
It lets developers inspect metrics and investigate problems from the terminal instead of relying only on a graphical dashboard.

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 B, and why

promql-cli scanned grade B with 2 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 today.

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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

6. **Store credentials in `~/.promql-cli.yaml` and `~/.promql_token`, chmod 600** — passing tokens as CLI args exposes them in shell history and process listings.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

0. **Always use the promql CLI** — never call the Prometheus HTTP API from Python scripts or shell `curl`. The CLI handles auth, formatting, and output consistently; Python API calls bypass all of that and produce raw JS

promql-cli — Prometheus Query CLI Skill

promql-cli (github.com/nalbury/promql-cli) is a Go CLI for querying, analyzing, and visualizing Prometheus metrics, plus PromQL fundamentals.

Reference Files

Read the relevant reference file(s) before executing tasks:

File When to read
references/installation.md User needs to install promql-cli or set up configuration (hosts, auth, token, password, multi-host)
references/usage.md User wants to discover metrics/exporters/labels, run queries, or choose output formats
references/graphing.md User wants to visualize Prometheus data as an ASCII chart in the terminal
references/debugging.md User is investigating a performance issue, latency, errors, saturation, data gaps, or query cost issues
references/promql-reference.md User needs help writing PromQL, understanding metric types, functions, or aggregations

For most tasks, read references/usage.md. For PromQL help, read references/promql-reference.md. When debugging, read both references/debugging.md and references/promql-reference.md.

Setup Check

Before running any query, verify that a host is configured:

promql 'up'   # succeeds if host is reachable; fails with connection error if not configured
# or
promql --host xxx 'up'

Recognize these errors as a configuration/auth problem and refer to references/installation.md:

Error Cause
dial tcp ... connection refused No host running at the configured address
dial tcp ... no such host Hostname not resolved — wrong host in config
error querying prometheus: ...401... Bearer token missing or invalid
error querying prometheus: ...403... Token valid but insufficient permissions
please specify an authentication type Auth flags partially set — use config file instead

If any of these appear, do not create config files on behalf of the user — config files may contain credentials (tokens, passwords) that must never pass through an LLM. Instead, guide the user to set it up themselves:

What ships with it

6 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.

promql-cli is a skill published in the GitHub repository samber/cc-skills (201 stars, last pushed today), licensed MIT. It adds 89 tokens to every session and 1,702 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it B with 2 findings (asks for root, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
