Reason about cloud compromise on the identity and control-plane graph, not the network diagram — because in cloud the control plane is an internet-reachable API authorized by credentials, it sits beside the data plane rather than above it behind a firewall, and a stolen key is one AssumeRole from the whole account. Use whenever the system is AWS/Azure/GCP/Kubernetes and the question is attack path, blast radius, privilege escalation, or "how bad is this": an SSRF that can reach the metadata…

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 Control-Plane Reasoning

On-prem intuition fails in cloud for one structural reason: **the control plane is an
API.** Deleting every snapshot, minting a new admin, exfiltrating a database via a
signed URL, backdooring the identity system — none of it touches the network you drew.
It is an authenticated call to `*.amazonaws.com` / `management.azure.com` /
`googleapis.com`, reachable from anywhere, authorized by a credential. The firewall
that guards the *data plane* (the running workload, the disk, the packets) does not
sit in front of the *control plane*, and the thing an attacker actually wants is the
control plane. Model the network and you have modeled the part that matters least.

The reframes this skill forces, each of which flips a severity most reviewers get
wrong:

- **An SSRF in cloud is usually credential theft, not information disclosure** — if it
  can reach the instance metadata endpoint, it reads the instance-profile credentials
  and becomes whatever that role is. Severity is set by the role, not by the SSRF.
- **Privilege escalation is an API call, not an exploit** — no memory corruption

How to install

The exact contents, by fingerprint
mdr add annatchijova/skills/cloud-control-plane-reasoning@sha256:6ce6ffd1c724c1ed

The line at the top of this page pins the label git:20260825.a84759b, 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.
