crowdsec

---

This is an Agent Skill that turns Claude/Codex/... into a hands-on CrowdSec operator. Ask it to stand up an engine, wire a bouncer, enable the WAF, or figure out why nothing's getting blocked — it knows the cscli commands, the config layout, the failure modes, and the safe way through each of them across bare-metal/systemd, Docker, OpnSense and Kubernetes/Helm.

What it covers

Area	Covered
Install	bare-metal/systemd · Docker · Kubernetes/Helm · OpnSense · Console enrollment
Bouncers	firewall (iptables/nftables/ipset) · nginx · traefik · caddy · apache · and more
WAF / AppSec	deploy · configure · troubleshoot the AppSec component
Hub	install collections/parsers/scenarios · update · debug
Configure	acquisition · profiles & ban durations · notifications · allowlists
Operate	health checks & smoke tests · upgrades & rollback · multi-server / remote LAPI / mTLS
Debug	logs not parsing · no alerts firing · bouncer not blocking · specific errors

🚀 Install

The skill loads automatically once installed. Just talk to Claude about CrowdSec.

On Claude

/plugin marketplace add crowdsecurity/crowdsec-skill
/plugin install crowdsec@crowdsecurity

Update later with:

/plugin marketplace update crowdsecurity

On Codex: install the skill with:

skill-installer crowdsecurity/crowdsec-skill

On Claude.ai (web)

Download crowdsec-skill-vX.Y.Z.zip from the latest release and upload it in the web skill uploader.

Or directly with skills.sh

npx skills add  crowdsecurity/crowdsec-skill

💬 Example prompts

Once installed, Claude picks the skill up whenever your prompt involves CrowdSec:

• "Install CrowdSec on this server and set up the nginx bouncer."
• "Deploy CrowdSec in my Kubernetes cluster and enroll it in the Console."
• "Enable the WAF / AppSec on my server."
• "CrowdSec doesn't detect attacks on my nginx server, why?"
• "There's a decision for this IP but it's not being blocked."
• "Migrate my fail2ban jails to CrowdSec."

What it does not do

This is an operational skill. It deploys, configures, and debugs CrowdSec — it does not author detection content. Writing a parser, scenario, or WAF (AppSec) rule is out of scope.

For authoring, head to the CrowdSec Hub and the detection-engineering docs.
