What it does

Configuring Load Balancers is an agent skill from jeremylongshore/tons-of-skills-marketplace. Configure use when configuring load balancers including ALB, NLB, Nginx, and HAProxy. Trigger with phrases like "configure load balancer", "create ALB", "setup nginx load balancing", or "haproxy configuration". Generates production-ready configurations with health checks, SSL termination, sticky sessions, and traffic distribution rules.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 11 other files, including scripts, reference files and assets (for example `assets/README.md`, `references/README.md` and `references/errors.md`). Compatibility notes: Designed for Claude Code

It sits in DevOps & Cloud, covering Cloud networking. It works with NGINX. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.

When your agent uses it

  • Configuring load balancers including ALB
  • With phrases like configure load balancer
  • Setup nginx load balancing
  • Haproxy configuration

Example prompts

  • “configure load balancer”
  • “create ALB”
  • “setup nginx load balancing”
  • “/configuring-load-balancers”

Requirements

  • Python 3
  • Compatibility (from SKILL.md): Designed for Claude Code
  • Pre-approved tools (allowed-tools): Read, Write, Edit, Grep, Glob, Bash(aws:*), Bash(gcloud:*), Bash(nginx:*)

Workflow steps

9 steps, taken from the first numbered list in SKILL.md.

  1. Select load balancer type based on requirements: ALB for HTTP/HTTPS with path routing, NLB for TCP/UDP with static IPs, Nginx for on-prem…
  2. Define the backend pool: list all backend server addresses, ports, and weights for weighted distribution
  3. Configure health checks with appropriate interval (10-30s), timeout (5s), healthy threshold (3), and unhealthy threshold (2)
  4. Set up SSL/TLS termination: configure certificates, redirect HTTP to HTTPS, set minimum TLS version to 1.2
  5. Define routing rules: path-based routing (/api -> API pool, /static -> CDN), host-based routing (api.example.com -> API)
  6. Enable session persistence (sticky sessions) using cookies or source IP affinity where needed for stateful applications
  7. Add connection draining to gracefully handle backend removal during deployments
  8. Configure logging and monitoring: access logs to S3/CloudWatch, request metrics, error rate dashboards
  9. Test the configuration: validate syntax (nginx -t, HAProxy config check), verify traffic distribution, and confirm failover behavior

What it can do on your machine

Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Write
    • Edit
    • Grep
    • Glob
    • Bash(aws:*)
    • Bash(gcloud:*)
    • Bash(nginx:*)

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 2 files in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • openssl

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • nginx.org
    • haproxy.org
    • docs.aws.amazon.com
    • cloud.google.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Designed for Claude Code

    From compatibility in the SKILL.md frontmatter.

Context cost

Configuring Load Balancers loads about 1.2k tokens when it runs, and up to ~1.5k if it reads all its reference files. Until then it costs about 91 tokens; SKILL.md has 505 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~91
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Configuring Load Balancers

Overview

Configure load balancers across AWS (ALB, NLB), GCP (HTTP(S) LB, TCP/UDP LB), Nginx, and HAProxy. Generate production-ready configurations with health checks, SSL/TLS termination, path-based and host-based routing, sticky sessions, rate limiting, and traffic distribution rules for high-availability deployments.

Prerequisites

  • Backend servers identified with IPs, DNS names, and ports
  • Load balancer type determined: L4 (NLB, HAProxy TCP) or L7 (ALB, Nginx, HAProxy HTTP)
  • SSL/TLS certificates available (ACM, Let's Encrypt, or self-signed) if using HTTPS
  • Health check endpoints defined on backend services (e.g., /health returning 200)
  • Cloud provider CLI installed for managed load balancers (aws, gcloud)

Instructions

  1. Select load balancer type based on requirements: ALB for HTTP/HTTPS with path routing, NLB for TCP/UDP with static IPs, Nginx for on-prem reverse proxy, HAProxy for high-performance TCP/HTTP
  2. Define the backend pool: list all backend server addresses, ports, and weights for weighted distribution
  3. Configure health checks with appropriate interval (10-30s), timeout (5s), healthy threshold (3), and unhealthy threshold (2)
  4. Set up SSL/TLS termination: configure certificates, redirect HTTP to HTTPS, set minimum TLS version to 1.2
  5. Define routing rules: path-based routing (/api -> API pool, /static -> CDN), host-based routing (api.example.com -> API)
  6. Enable session persistence (sticky sessions) using cookies or source IP affinity where needed for stateful applications
  7. Add connection draining to gracefully handle backend removal during deployments
  8. Configure logging and monitoring: access logs to S3/CloudWatch, request metrics, error rate dashboards
  9. Test the configuration: validate syntax (nginx -t, HAProxy config check), verify traffic distribution, and confirm failover behavior

Output

  • Nginx configuration files (nginx.conf, site configs) with upstream blocks and server directives
  • HAProxy configuration (haproxy.cfg) with frontend/backend sections
  • Terraform HCL for AWS ALB/NLB with target groups, listeners, and rules
  • GCP load balancer Terraform with backend services, URL maps, and health checks
  • SSL certificate configuration and renewal automation

Error Handling

ErrorCauseSolution
502 Bad GatewayBackend server unreachable or not respondingVerify backend IPs, ports, and firewall rules; check backend service health
SSL certificate verify failedCertificate expired, wrong chain, or key mismatchVerify certificate validity and chain with openssl s_client; regenerate if needed
Target is unhealthyHealth check endpoint returning non-200 or timing outVerify health check path returns 200; increase timeout if backend is slow to respond
nginx: configuration file test failedSyntax error in Nginx configurationRun nginx -t to identify the specific error line; fix syntax and test again
Session persistence not workingCookie-based stickiness misconfigured or client not sending cookiesVerify cookie name matches; use IP-based affinity as fallback for non-browser clients

Examples

  • "Configure an AWS ALB with HTTPS listener, path-based routing to two target groups (/api and /web), and health checks on /health."
  • "Generate an Nginx reverse proxy config with upstream servers, sticky sessions via cookie, and rate limiting at 100 req/s per IP."
  • "Create a HAProxy configuration for TCP load balancing across 4 database read replicas with health checks and connection draining."
