wazuh-active-response

wazuh-active-response is a skill for Claude Code from gensecaihq/Wazuh-Autopilot. It costs 53 tokens per session (1,503 once invoked), scanned A, original, MIT.

A guide to how Wazuh active response works: the system sends a command to an endpoint, where a deployed script must run it. It explains why accepting a command is not proof that the endpoint carried it out.

In plain words
What is it for?
Use it before planning or checking actions such as blocking an IP address on one or more monitored computers.
Why use it?
It prevents false confidence about containment and highlights important details such as missing scripts, permanent API-triggered blocks and the need to verify results.

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

wazuh-active-response 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 yesterday.

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.

Wazuh Active Response

Agents never execute actions. The response-planner proposes (propose_action); the autonomy policy and human approvers decide; the platform executor calls the Wazuh MCP action tool; the responder verifies. This skill explains what happens underneath so plans are realistic and verification is honest.

How Wazuh AR works

  1. The Wazuh API (via the MCP server) sends an active-response command to one or more agents.
  2. The agent runs a script of that name from its active-response bin directory. If the script isn't deployed on that agent, nothing happens on the host.
  3. The API returns as soon as the manager accepts and dispatches the command ("AR command was sent to the agent") — this is not proof of execution.
  4. The script logs its outcome; Wazuh turns that log into an alert in the active_response group.
  5. API-triggered AR is permanent: Wazuh ignores the timeout for API-triggered commands, so a block stays until explicitly removed (rollback), unlike rule-triggered AR with a timeout.
