elasticsearch SKILL.md skillA

elasticsearch from lynricsy/hyperskills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add lynricsy/hyperskills/elasticsearch@v2026.10.15

Pins v2026.10.15 in mdr.lock. Pin the fingerprint instead.

Designs and tunes Elasticsearch mappings, queries, search relevance and indexes.

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

# elasticsearch

## Scope

Covers Elasticsearch itself: index and mapping design, text analysis, the Query DSL, ES|QL,
relevance and its measurement, aggregations, vector and semantic retrieval, data streams and the
index lifecycle, reindexing, shard and heap capacity, cluster allocation, diagnostics, and
cluster-level security.

The body is written against **Elasticsearch 9.5** (9.5.3 at time of writing; 8.19 is the last 8.x
series). Rules that need a particular version carry a gate such as `(9.4+)`. Facts marked as
measured were run against a single-node 9.5.3 instance on a basic licence.

Not covered:

- Relational schema, SQL and plan tuning. Use the `postgres` skill.
- Document-database modelling and aggregation pipelines in MongoDB. Use the `mongodb` skill.
- Key-value caching, expiry and eviction. Use the `redis` skill.
- Log and metric collection pipelines, agents and shippers, alerting rules, SLOs, and working back
  from a production alert to a code path. Use the `observability` skill. Index and query design
  for data that happens to be logs is in scope; getting the
  logs there and paging someone about them is not.

How to install

The exact contents, by fingerprint

mdr add lynricsy/hyperskills/elasticsearch@sha256:2308c962a3502662

The line at the top of this page pins the label v2026.10.15, 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.
