elasticsearch-esql

elasticsearch-esql is a skill for Claude Code, Codex from elastic/cursor-plugins. It costs 47 tokens per session (5,649 once invoked), scanned A, a copy of elasticsearch-esql, Apache-2.0.

A way to query and analyze data in Elasticsearch, a search and analytics system, using ES|QL, its pipe-based query language. Queries can filter records, calculate summaries, sort results, and limit output.

In plain words
What is it for?
Use it to run ES|QL queries, aggregate and inspect Elasticsearch data, analyze logs or metrics, and create charts or dashboards from query results.
Why use it?
It helps developers explore logs, metrics, and other indexed data without building each analysis from scratch, while accounting for differences between Elasticsearch versions.

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

elasticsearch-esql 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 4d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/esql.js), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Elasticsearch ES|QL

Execute ES|QL queries against Elasticsearch.

What is ES|QL?

ES|QL (Elasticsearch Query Language) is a piped query language for Elasticsearch. It is NOT the same as:

  • Elasticsearch Query DSL (JSON-based)
  • SQL
  • EQL (Event Query Language)

ES|QL uses pipes (|) to chain commands: FROM index | WHERE condition | STATS aggregation BY field | SORT field | LIMIT n

Prerequisite: ES|QL requires _source to be enabled on queried indices. Indices with _source disabled (e.g., "_source": { "enabled": false }) will cause ES|QL queries to fail.

Version Compatibility: ES|QL was introduced in 8.11 (tech preview) and became GA in 8.14. Features like LOOKUP JOIN (8.18+), MATCH (8.17+), and INLINE STATS (9.2+) were added in later versions. On pre-8.18 clusters, use ENRICH as a fallback for LOOKUP JOIN (see generation tips). INLINE STATS and counter-field RATE() have no fallback before 9.2. Check references/esql-version-history.md for feature availability by version.

Cluster Detection: Use the GET / response to determine the cluster type and version:

  • build_flavor: "serverless" — Elastic Cloud Serverless. version.number tracks the stack line under active development (next minor from main), so clients that only semver-compare may treat Serverless as “latest.” Do not use version.number to gate features: if build_flavor is "serverless", assume all GA and preview ES|QL features are available.
  • build_flavor: "default" — Stack (self-managed or Cloud-hosted). Use version.number for feature availability.
  • Snapshot builds have version.number like 9.4.0-SNAPSHOT. Strip the -SNAPSHOT suffix and use the major.minor for version checks. Snapshot builds include all features from that version plus potentially unreleased features from development — if a query fails with an unknown function/command, it may simply not have landed yet. Elastic employees commonly use snapshot builds for testing.

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.
