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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00021 | $0.00586 |
| Opus 5 | $0.00010 | $0.00293 |
| Sonnet 5 | $0.00004 | $0.00117 |
| Haiku 4.5 | $0.00002 | $0.00059 |
Grade A, and why
dns-management 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.

DNS Management
Table of Contents
Overview
Implement DNS management strategies for traffic routing, failover, geo-routing, and high availability using Route53, Azure DNS, or CloudFlare.
When to Use
- Domain management and routing
- Failover and disaster recovery
- Geographic load balancing
- Multi-region deployments
- DNS-based traffic management
- CDN integration
- Health check routing
- Zero-downtime migrations
Quick Start
Minimal working example:
# route53-setup.yaml
apiVersion: v1
kind: ConfigMap
metadata:
name: route53-config
namespace: operations
data:
setup-dns.sh: |
#!/bin/bash
set -euo pipefail
DOMAIN="myapp.com"
HOSTED_ZONE_ID="Z1234567890ABC"
PRIMARY_ENDPOINT="myapp-primary.example.com"
SECONDARY_ENDPOINT="myapp-secondary.example.com"
echo "Setting up Route53 DNS for $DOMAIN"
# Create health check for primary
PRIMARY_HEALTH=$(aws route53 create-health-check \
--health-check-config '{
"Type": "HTTPS",
"ResourcePath": "/health",
"FullyQualifiedDomainName": "'${PRIMARY_ENDPOINT}'",
"Port": 443,
// ... (see reference guides for full implementation)

Best Practices
✅ DO
- Use health checks with failover
- Set appropriate TTL values
- Implement geolocation routing
- Use weighted routing for canary
- Monitor DNS resolution
- Document DNS changes
- Test failover procedures
- Use DNS DNSSEC
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.
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.

dns-management is a skill published in the GitHub repository aj-geddes/useful-ai-prompts (338 stars, last pushed 6mo ago), licensed MIT. It adds 21 tokens to every session and 586 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.
