cloud-networking SKILL.md skillA
cloud-networking from amey-thakur/ai-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add amey-thakur/ai-skills/cloud-networking@git:20260720.3c9eba4Pins git:20260720.3c9eba4 in mdr.lock. Pin the fingerprint instead.

Lay out VPCs, subnets, private connectivity, and DNS so services reach each other privately and the internet only on purpose. Use when designing cloud network topology or debugging cross-service connectivity.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Cloud networking
Default-deny is the design stance: nothing reaches the internet, another
VPC, or your data stores unless a rule you wrote says so. Everything
else is plumbing to make that stance livable.
## Method
1. **Plan address space before the first VPC.** Non-overlapping CIDRs
across VPCs, regions, and the office/VPN ranges, sized with 4x
growth headroom, recorded in one registry. Overlaps discovered at
peering time cost re-IP projects; ten minutes of spreadsheet now
prevents them.
2. **Tier subnets by exposure.** Public subnets hold only entry points
(load balancers, NAT); private subnets hold compute; isolated
subnets hold data stores with no internet path at all. Workloads
never get public IPs; inbound flows through the LB, outbound through
NAT (watch its processing cost; see cloud-cost-optimization).
3. **Prefer identity rules over IP rules.** Security groups referencing
other security groups ("db-sg allows app-sg on 5432") survive
autoscaling and re-IPs; CIDR-based rules rot. Keep NACLs at coarse
subnet guardrails; per-flow logic lives in security groups where
state is handled for you.

How to install
mdr add amey-thakur/ai-skills/cloud-networking@sha256:72ad90efd55f2ea6The line at the top of this page pins the label git:20260720.3c9eba4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
