tune-prometheus-config SKILL.md skillA
tune-prometheus-config from prometheus/prometheus-mcp is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add prometheus/prometheus-mcp/tune-prometheus-config@git:20260721.4db318bPins git:20260721.4db318b in mdr.lock. Pin the fingerprint instead.

Review and tune Prometheus configuration and performance. Use for scrape interval, retention, storage, relabeling, flag, and capacity questions, or when Prometheus itself is slow or resource-hungry; recommends concrete config changes.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Optimizing Prometheus Configuration and Performance Assess whether Prometheus is configured sensibly for its actual load: scrape configuration, storage and retention, query behavior, and resource headroom. The goal is a small set of concrete, justified configuration changes -- not a tour of every setting. ## Getting oriented - config returns the full scrape and evaluation configuration; flags the complete command line; runtime_info retention and Go runtime settings; build_info the version. - tsdb_stats quantifies the load: series counts, cardinality, and which metrics and labels dominate memory. - query and range_query against Prometheus's own metrics (prometheus_*, process_*, go_*) show how it is coping with that load. - Prometheus's storage metrics show how the TSDB is keeping up: prometheus_tsdb_compaction_duration_seconds and prometheus_tsdb_wal_fsync_duration_seconds reflect disk pressure, and nonzero prometheus_tsdb_compactions_failed_total or prometheus_tsdb_wal_corruptions_total need attention before any tuning. ## Topics worth exploring Treat these as starting points and dig where the numbers look off: …

How to install
mdr add prometheus/prometheus-mcp/tune-prometheus-config@sha256:30dec8413a2297afThe line at the top of this page pins the label git:20260721.4db318b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
