security-alert-triage

security-alert-triage is a skill for Claude Code from elastic/agent-skills. It costs 39 tokens per session (3,197 once invoked), scanned A, original, Apache-2.0.

A workflow for investigating Elastic Security alerts, which are warnings produced by Elastic's security monitoring system. It gathers context, classifies the alert, records a case, and acknowledges it.

In plain words
What is it for?
Use it to fetch the next alert, run searches, investigate the evidence, create or find a case, and acknowledge the alert.
Why use it?
It gives alert investigations a defined order and keeps the findings documented before the alert is closed. It also identifies the required Elastic and case-management setup.

    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

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

security-alert-triage 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 9d ago.

The scan reads SKILL.md. This mod also ships 5 executable files (scripts/acknowledge-alert.js, scripts/es-client.js, scripts/fetch-next-alert.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.

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.

How it starts

The opening of the file, as written. The whole thing — 285 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Alert Triage

Analyze Elastic Security alerts one at a time: gather context, classify, create a case, and acknowledge. This skill depends on the case-management skill for case creation.

Prerequisites

Install dependencies before first use from the skills/security directory:

cd skills/security && npm install

Set the required environment variables (or add them to a .env file in the workspace root):

export ELASTICSEARCH_URL="https://your-cluster.es.cloud.example.com:443"
export ELASTICSEARCH_API_KEY="your-api-key"
export KIBANA_URL="https://your-cluster.kb.cloud.example.com:443"
export KIBANA_API_KEY="your-kibana-api-key"

Quick start

All commands from workspace root. Always fetch → investigate → document → acknowledge. Call the tools directly — do not read the skill file or explore the workspace first.

node skills/security/alert-triage/scripts/fetch-next-alert.js
node skills/security/case-management/scripts/case-manager.js find --tags "agent_id:<id>"
node skills/security/alert-triage/scripts/run-query.js --query-file query.esql --type esql
node skills/security/case-management/scripts/case-manager.js create --title "..." --description "..." --tags "classification:..." "agent_id:<id>" --severity <level> --yes
node skills/security/case-management/scripts/case-manager.js attach-alert --case-id <id> --alert-id <id> --alert-index <index> --rule-id <uuid> --rule-name "<name>" --yes
node skills/security/alert-triage/scripts/acknowledge-alert.js --related --agent <id> --timestamp <ts> --window 60 --yes

Common multi-step workflows

Task Tools to call (in order)
End-to-end triage fetch_next_alertrun_query (context) → case_manager create (case) → acknowledge_alert
Gather context run_query (process tree, network, related alerts)
Create case after classification case_manager create → case_manager attach-alert
Acknowledge after triage acknowledge_alert (related mode for batch)

What ships with it

6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
