elasticsearch-cluster-health

elasticsearch-cluster-health is a skill for Claude Code, Codex from elastic/cursor-plugins. It costs 68 tokens per session (2,784 once invoked), scanned A, a copy of elasticsearch-cluster-health, Apache-2.0.

A read-only Elasticsearch cluster-health diagnostic tool. A cluster is the group of Elasticsearch servers working together; its status shows whether data copies are assigned and available.

In plain words
What is it for?
Use it to investigate unassigned shards, allocation failures, and non-green cluster health, then report a likely remedy for an operator to apply.
Why use it?
It narrows a yellow or red cluster status to the most likely cause without changing the cluster. This helps distinguish reduced redundancy from problems that affect primary data copies.

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-cluster-health scanned grade A with 0 findings 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 7d ago.

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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Diagnose Cluster Health

Triage a non-green Elasticsearch cluster read-only: localize the problem, classify the allocation decider, and report the single most likely cause with remediation. Never mutate cluster state — surface findings and let the operator act.

Environment Configuration

This skill executes Elasticsearch operations through the elastic CLI. If the elastic CLI is not installed, tell the user what it is needed for. Do not guess credentials, call the HTTP API directly, or attempt other workarounds.

This skill references operations in HTTP-shorthand form (e.g., GET /, GET /_cat/indices, GET /{index}/_mapping, GET /{index}/_settings/index.mode, POST /_query). The Operations table at the end of this document maps each shorthand to the equivalent elastic CLI command — always use the CLI rather than calling the HTTP API directly.

Process

  1. Read the overall status. Call GET /_cluster/health. The status field is the verdict:

    • green — every primary and replica is assigned. Report healthy and stop.
    • yellow — every primary is assigned but at least one replica is not. Data remains readable; redundancy is degraded. This is not data loss.
    • red — at least one primary is unassigned. Data for that shard is unavailable; treat as urgent.

    Also read unassigned_shards, initializing_shards, and relocating_shards. The decision: continue only when status is yellow or red. If initializing_shards > 0 and unassigned_shards == 0, the cluster is recovering on its own — call GET /_cat/recovery to confirm progress, wait, and re-check GET /_cluster/health before escalating.

    Data needed: cluster-wide status and shard counters.

  2. Localize the problem to one index. Call GET /_cluster/health?level=indices and pick the index that drives the cluster-wide status:

    • Any red index outranks every yellow index.
    • Among reds or yellows, prefer the index with the most unassigned_shards.
    • A red system index (.security, .kibana*, .fleet-*) outranks application indices because the rest of the stack depends on 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.
