Various static analysis and testing tools for managing PromQL compatible monitoring stacks
Skill Claude CodeCodex
Query a live Prometheus's historical ALERTS series to statistically recommend better 'for:' hold-down durations, reducing spurious short-lived alerts and alert fatigue. Use interactively when an alert is firing too often/too briefly and needs its hysteresis tuned, or when auditing a rules file's for: values against…
Skill Claude CodeCodex
Identify Prometheus alert/recording rules that have no promtool unit-test coverage, and scaffold true-positive/false-positive/hysteresis test-case skeletons for them. Use when bootstrapping unit tests for new or existing PromQL rules, or auditing test coverage of a rules file. Fully hermetic: reads only local…

Render end-to-end previews of what an alert notification will actually look like (plain-text email, HTML email, Slack attachment JSON, raw webhook JSON) by replaying a Prometheus unit-test file's expected alerts through a live Alertmanager. Effectively a "print preview" for alerts. Use to review notification…
Skill Claude CodeCodex
Enforce that PromQL expressions (and, optionally, alert definitions) carry a required set of labels — e.g. job, namespace, cluster — to prevent label collisions in multi-tenant Prometheus/Thanos/Cortex/Mimir setups. Use when validating rule YAML for required labels or required alert labels, interactively or as a CI…

Orchestrate all six o11y-analysis-tools PromQL/Alertmanager CLIs together as one workflow for a repo of Prometheus/Alertmanager rules — decide which tools are hermetic and CI-safe (promql-fmt, label-check, autogen-promql-tests, and e2e-alertmanager-test when given a skeleton Alertmanager config) versus…
Skill Claude CodeCodex
Format and lint PromQL expressions embedded in Prometheus/Thanos/Cortex/Mimir rule YAML files — multiline layout, redundant aggregation-clause removal, aggregation-style consistency, and naming/instrumentation best-practice checks. Use whenever writing, editing, or reviewing alert/recording rule YAML, or as a CI…
Skill Claude CodeCodex
Query a live Prometheus's historical ALERTS series to find alert rules that haven't fired in a long time — "dead code analysis" for alerting rules, surfacing candidates for deletion or threshold review. Use interactively during alert-quality/on-call hygiene reviews, not as a CI gate. Requires a live Prometheus with…
