Structure cloud IAM with role-based access, short-lived credentials, and permission boundaries that hold at scale. Use when designing cloud access control or cleaning up accumulated permissions.
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
# IAM design Identity is the real security perimeter in the cloud. The design goal: every principal holds the least it needs, nothing is permanent, and the whole arrangement is reviewable by a human in an afternoon. ## Method 1. **Grant to roles, never to individuals.** Humans assume roles (engineer, oncall, auditor) through SSO group membership; workloads get per-service roles. Direct user grants are unreviewable snowflakes; when the org chart changes, group membership changes and IAM follows. 2. **Kill long-lived credentials.** Humans: SSO with MFA into temporary session credentials. Workloads: platform-issued identity (instance profiles, workload identity, OIDC federation from CI), never access keys in env vars or repos (see secrets-management). Any static key that must exist gets rotation and a usage alarm. 3. **Scope by resource and condition, not service-wide stars.** `s3:GetObject` on `arn:...:bucket/tenant-a/*`, conditions on VPC source, tags, or org ID. `Action: *` on `Resource: *` grants appear in incident reports, not designs. Separate read from write roles; most consumers only need read. …

How to install
mdr add amey-thakur/ai-skills/iam-design@sha256:9f5e8e42c16190c7The 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.
