Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00018 | $0.00379 |
| Opus 5 | $0.00009 | $0.00189 |
| Sonnet 5 | $0.00004 | $0.00076 |
| Haiku 4.5 | $0.00002 | $0.00038 |
Grade A, and why
haproxy 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.
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.
What it actually says
HAProxy
HAProxy is the standard for high-performance load balancing. HAProxy 3.0 (2025) adds Syslog Load Balancing and improved HTTP/3 QUIC support.
When to Use
- High Traffic: Handling millions of requests per second.
- L4 Balancing: TCP proxying for Database replicas, Redis, or non-HTTP protocols.
- Advanced Logic: Complex ACLs, rate limiting, and sticky sessions.
Quick Start
frontend http_front
bind *:80
default_backend web_servers
backend web_servers
balance roundrobin
server web1 10.0.0.1:80 check
server web2 10.0.0.2:80 check
Core Concepts
Frontend / Backend
Frontend defines how requests enter (ports, certs). Backend defines where they go and how (algorithms, health checks).
ACLs
Access Control Lists. Powerful conditionals.
acl is_api path_beg /api
use_backend api_servers if is_api
Stick Tables
In-memory storage for tracking events (e.g. rate limiting by IP).
Best Practices (2025)
Do:
- Use Data Plane API: For dynamic configuration without reloads.
- Enable Prometheus Exporter: Built-in metrics endpoint.
- Tune
maxconn: Critical for preventing resource exhaustion.
Don't:
- Don't use as Web Server: It is a proxy. Use Nginx/Caddy for serving static files.

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.

haproxy is a skill published in the GitHub repository G1Joshi/Agent-Skills (12 stars, last pushed 7mo ago), licensed MIT. It adds 18 tokens to every session and 379 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
