  iam-deceptive-escalation-auditoranyshift-io/sre-skills · 17

  Audit the union of every IAM policy attached to one principal for privilege-escalation paths that no single statement reveals, and for apparent escalations that are already neutralised. Resolves the effective permission set across all attached policies (Allow minus blanket Deny), then checks the cross-statement escalation combos (iam:PassRole + a compute-launch action, policy-rewrite-in-place, function-code hijack, self-attach admin, trust-policy rewrite + assume, credential minting for another identity), the wildcard grants (Action '*' on Resource '*', service-level wildcards, Allow+NotAction), and the trust-policy exposure. Its discipline is symmetric: it does NOT flag a PassRole combo killed by an explicit Deny, an Action '*' pinned to one bucket, an sts:AssumeRole whose target does not trust back, a mutation kit capped by a permissions-boundary Deny, or a cross-account assume sealed by an unsatisfiable Condition. Reports findings with severity and a fix, then names what a single principal's policies cannot answer (the privileges of a passed/assumed role, the permissions boundary, the org SCPs). Use when asked to audit an IAM policy, role, or user for escalation, over-broad grants, or "can this principal become admin." Vendor-neutral; runs offline against the policy JSON with no Anyshift account.

  kubectl-investigatoranyshift-io/sre-skills · 17

  Investigate a live or recent incident in a Kubernetes cluster. Anchor the window, bisect the change surface (rollouts, ConfigMaps/Secrets, RBAC, HPA/cluster changes, CronJobs), classify against four reference failure paths (OOM, DNS, cascading-failure, deploy-correlator), confirm the hypothesis with three independent signals, quantify blast radius, and propose mitigation before root cause. Use whenever an agent is asked "what is breaking in the cluster right now", "why did this pod/Deployment just page", "did the rollout cause Z", or to triage an active Kubernetes incident. Vendor-neutral by default (works with kubectl, kube-state-metrics, and whatever telemetry you have); an opt-in Anyshift integration is documented separately.

  s3-estate-calibration-auditoranyshift-io/sre-skills · 17

  Audit an estate of AWS S3 buckets for the one bucket that is genuinely publicly or cross-account exposed, without over-flagging the many buckets that READ as exposed but are neutralised. Resolves each bucket's EFFECTIVE verdict by composing four layers (Block Public Access x bucket policy x bucket ACL x access points), never one layer alone, then rolls the per-bucket verdicts up into an estate verdict. Its discipline is symmetric: BPA (RestrictPublicBuckets / BlockPublicPolicy) neutralises a Principal '*' policy but NOT a cross-account grant; IgnorePublicAcls kills a public-group ACL grant but NOT a cross-account canonical-user grant; a narrowing Condition (org id, ExternalId, SourceIp, access-point delegation) scopes a Principal '*' so it is not public. On a needle estate it names the ONE live bucket as the primary finding; on a clean estate it reports NO live exposure and does not manufacture findings. Then it states what the bucket configs alone cannot answer (per-object ACLs, CloudFront/CDN fronting, the trusted principals' identity policies, account-level BPA dependency, data sensitivity). Use when asked to review an S3 bucket fleet for public exposure, cross-account access, or whether the estate is clean. Vendor-neutral; runs offline against describe-bucket / get-bucket-policy / get-bucket-acl / list-access-points JSON with no Anyshift account.

  sg-deceptive-reachability-auditoranyshift-io/sre-skills · 17

  Audit a fleet of AWS security groups for the multi-hop lateral-movement path that no single ingress rule reveals. Builds a directed reachability graph from the SG-to-SG references (an ingress rule on SG B naming SG A means a host in A can reach B), adds an internet edge for every 0.0.0.0/0 rule, then composes those edges into the transitive closure from a named entry point (the internet, or a compromised host). Reports the shortest reachable path to the crown-jewel tier, the blast radius, and any pivot/hub SG that bridges otherwise-isolated regions, each ranked by severity with a fix. Its discipline is symmetric: on a segmented or orphaned fleet where the chain does NOT reach the crown jewel, it reports clean and names the boundary instead of fabricating a path. Then it states what the SG graph alone cannot answer (live host membership, route tables, NACLs, app-layer auth). Use when asked to review a security-group fleet for lateral movement, blast radius, or whether the internet can reach a sensitive tier. Vendor-neutral; runs offline against describe-security-groups + describe-instances JSON with no Anyshift account.

  sqs-queue-auditoranyshift-io/sre-skills · 17

  Audit a single AWS SQS queue's configuration for the misconfigurations that silently drop or re-deliver messages while every attribute reads as fine. Parses the GetQueueAttributes output (and the referenced dead-letter queue), checks the redrive path (DLQ present, maxReceiveCount band, DLQ-vs-source retention ordering), the message lifecycle (poison messages aging out before they reach the DLQ, default visibility timeout, short retention), and exposure (open resource policy, encryption at rest, FIFO dedup contract). Reports findings with severity and a recommendation, then names the boundary: the questions a single queue's config cannot answer (consumer processing time, live behaviour, the IAM union, the producers and consumers on either side). Use when asked to review, harden, or sanity-check an SQS queue, or to explain why messages are going missing. Vendor-neutral; runs offline against the queue attributes with no Anyshift account.
