oncall-triage

oncall-triage is a skill for Claude Code from grafana/gcx. It costs 157 tokens per session (2,230 once invoked), scanned A, original, Apache-2.0.

A tool for reviewing active Grafana OnCall alert groups—the grouped incidents currently paging an on-call team. It can list, inspect, acknowledge, silence, or resolve those groups.

In plain words
What is it for?
Use it to review the on-call queue, inspect firing alerts, acknowledge alerts someone is handling, silence unwanted notifications, or resolve completed incidents.
Why use it?
It helps answer what is paging right now without confusing active incidents with the alert rules that caused them. It also keeps common triage actions in one workflow.

About the project

gcx is a command-line tool that lets people and AI coding agents manage and inspect Grafana Cloud, Enterprise, and open-source instances. It provides access to dashboards, alerts, SLOs, metrics, logs, and traces, with workflows for alert investigation, dashboard management, GitOps, and observability setup. Its catalogue entries provide agent instructions and extensions for using gcx.

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

oncall-triage scanned grade A with 1 finding 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 10d ago.

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.

OnCall Alert-Group Triage

OnCall alert groups are post-routing aggregations of alert deliveries — they answer "what is paging right now?". Grafana alert rules (under gcx alert rules) answer "why is rule X evaluating to firing?". This skill covers the OnCall side and pivots out when needed.

Core Principles

  1. Use gcx — do not call OnCall APIs directly (no curl, no HTTP libraries).
  2. The CLI emits structured diagnostics on stderr (hint:, note:, warn:; JSONL with class in agent mode). Pass them through.
  3. The default alert-groups list filter excludes resolved + child groups. Surface --all only when the user asks about history.
  4. Action verbs in agent mode require --force when matched count > 1. Never pre-fill --force without user confirmation.

Prerequisites

gcx configured with an active context that targets a Grafana stack with OnCall enabled. If not, use the setup-gcx skill first.

Triage Workflow

Step 1: List Active Alert Groups

gcx irm oncall alert-groups list

Default filter: state in {firing, acknowledged, silenced} and is_root=true (matches the OnCall UI). See --help for the full flag set; common narrowers are --state, --team <PK>, --integration <PK>, --escalation-chain <ID>, --mine, --max-age 24h. Team / integration / chain filters take IDs, not names — resolve first:

gcx irm oncall teams list -o json | jq -r '.[] | "\(.metadata.name): \(.spec.name)"' | grep -i "my team"
gcx irm oncall escalation-chains list

To attribute alert load to a rotation, filter by escalation chain, not integration: one integration routes through several chains to several schedules, and the alert group record carries no chain field of its own. Chain-filtered queries over the same integration return disjoint subsets.

Escape hatches: --all (drops both defaults — returns resolved + child groups), --include-child-groups, --state resolved.

For a historical window use --from / --to (RFC3339, unix timestamp, or now-30d); --max-age only anchors to now, and the two cannot be combined. --resolved-from / --resolved-to bound resolved_at instead. --acknowledged-by <user-id> / --resolved-by <user-id> attribute handling to a person.

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.

oncall-triage is a skill published in the GitHub repository grafana/gcx (594 stars, last pushed today), licensed Apache-2.0. It adds 157 tokens to every session and 2,230 once invoked, about $0.0008 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
