metricsql SKILL.md skillA
metricsql from xobotyi/cc-foundry is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add xobotyi/cc-foundry/metricsql@git:20260521.aae5685Pins git:20260521.aae5685 in mdr.lock. Pin the fingerprint instead.

VictoriaMetrics MetricsQL query language as a PromQL superset: rollup extensions, behavioral differences from PromQL (rate/increase semantics, implicit conversions, auto-aligned subqueries), label manipulation, WITH templates, keep_metric_names modifier, multiple-or filters, and query API enhancements. Invoke whenever task involves any interaction with MetricsQL or VictoriaMetrics queries — writing, debugging, optimizing, migrating PromQL to VictoriaMetrics, or reviewing.
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
# MetricsQL
VictoriaMetrics PromQL superset. Syntactically backwards-compatible; **semantically different** for a subset of queries.
Lead with the diffs — that's where users get burned. PromQL fundamentals live in the sibling `promql` skill; this covers
only what PromQL doesn't.
## References
- **Behavioral diffs from PromQL** — [`${CLAUDE_SKILL_DIR}/references/behavioral-diffs.md`]
`rate`/`increase`/`delta`/`changes` diffs, `_prometheus`-suffixed variants, scalar/instant-vector unification, NaN
handling, name retention, implicit conversions, auto-aligned subqueries, `default_rollup` lookback, staleness markers.
- **MetricsQL-only extensions** — [`${CLAUDE_SKILL_DIR}/references/extensions.md`] Rollup family, `WITH` templates,
multiple-`or` filters, `default`/`if`/`ifnot` ops, `group_left(*) prefix`, `keep_metric_names`, `[Ni]` step, numeric
suffixes, aggregate `limit N`, `boundsLabel`, fractional durations, Graphite, multi-line.
- **Full function catalog** — [`${CLAUDE_SKILL_DIR}/references/functions-catalog.md`] All rollup, transform,
label-manipulation, aggregate functions by category, with PromQL/MetricsQL provenance.

How to install
mdr add xobotyi/cc-foundry/metricsql@sha256:dcf9db1117ef9c69The line at the top of this page pins the label git:20260521.aae5685, 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.
