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 | $0.00000 | $0.00403 |
| Opus 5 | $0.00000 | $0.00201 |
| Sonnet 5 | $0.00000 | $0.00081 |
| Haiku 4.5 | $0.00000 | $0.00040 |
Grade A, and why
networking 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 6d 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
Skill: Cloud Networking
When to load
When designing VPC topology, configuring security groups, setting up NAT, or reviewing network architecture.
VPC Design (3-tier)
VPC (10.0.0.0/16)
├── Public subnets (10.0.1.0/24, 10.0.2.0/24) ← ALB, NAT Gateway
├── Private subnets (10.0.10.0/24, 10.0.11.0/24) ← App servers, K8s nodes
└── Isolated subnets (10.0.20.0/24, 10.0.21.0/24) ← RDS, ElastiCache
Security Group Rules (Default-Deny)
# App tier: only accepts traffic from ALB security group
resource "aws_security_group_rule" "app_from_alb" {
type = "ingress"
from_port = 8080
to_port = 8080
protocol = "tcp"
source_security_group_id = aws_security_group.alb.id
security_group_id = aws_security_group.app.id
}
# DB tier: only accepts traffic from app security group
resource "aws_security_group_rule" "db_from_app" {
type = "ingress"
from_port = 5432
to_port = 5432
protocol = "tcp"
source_security_group_id = aws_security_group.app.id
security_group_id = aws_security_group.db.id
}
Cost Optimization
- Use VPC Endpoints for S3/DynamoDB to avoid NAT Gateway costs
- NAT Gateway: one per AZ in production (not one shared)
- Transit Gateway for multi-VPC connectivity (cheaper than VPC peering at scale)
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.

networking is a skill published in the GitHub repository sawrus/agent-guides (17 stars, last pushed 10d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 403 tokens. 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.
