aws-samplesSkill

ecs-security

aws-samples/sample-apex-skills/skills/ecs-security/SKILL.md

Security and compliance guidance for Amazon ECS — "ECS was unable to assume the role", task role vs execution role, iam:PassRole, confused-deputy aws:SourceArn trust, Fargate vs EC2 shared responsibility, injecting Secrets Manager/SSM secrets (trailing-colon JSON-key gotcha), readonlyRootFilesystem / non-root / drop capabilities, ECS Exec governance, security-group-per-task, VPC endpoint policies, GuardDuty ECS Runtime Monitoring, ECR Inspector scanning, image signing, Fargate FIPS, or PCI/HIPAA/FedRAMP. Walks a discovery-driven 7-layer stack plus the AWS-canonical baseline and a 30/60/90 roadmap. Trigger even if "compliance" is never said — any ECS hardening, task-trust fix, or secrets-injection qualifies. Skip for EKS/Kubernetes (eks-security), GenAI/GPU security (ecs-genai), App Runner/Lambda, auditing a live estate's operational posture (ecs-operation-review — "audit my ECS security posture" matches both), or account-level security with no ECS angle.

aws-samplesSkill

eks-security

aws-samples/sample-apex-skills/skills/eks-security/SKILL.md

Read-only scripted security reviews of a live Amazon EKS cluster (exposed / not exposed / unknown), plus hardening and compliance guidance. (1) CVE and advisory review - "am I exposed to CVE-...", "check this AWS bulletin or GHSA against my cluster", "CVE review for EKS" - verdicts for add-ons and images; kubelet and node-OS items are review-only. (2) Security event response - compromised image or package, leaked credential, suspicious pod - scope, record, contain, snapshot, fix, verify. (3) Posture check - "would my cluster contain a compromised pod", IMDS, NetworkPolicy, PSA, identity, logging, GuardDuty, endpoint, supply chain. Also hardening and audit prep - 7-layer stack, CIS, HIPAA/PCI-DSS/FedRAMP/SOC 2, Pod Identity vs IRSA, Access Entries, image signing. Skip for EKS knowledge (eks-best-practices), Well-Architected review (eks-well-architected-review), upgrade readiness (eks-upgrade-check), an operational review (eks-operation-review), inventory (eks-recon), GenAI model security (eks-genai), non-EKS.

Use this skill when the user asks about hardening, asks about a security review, or asks about CSP for a third-party script (Stripe, Google Maps, fonts).

cicd-security

briiirussell/cybersecurity-skills/skills/cicd-security/SKILL.md

Audit CI/CD pipelines, GitHub Actions first and GitLab CI and CircleCI briefly, for the paths that give an outsider code execution, secrets or a write token: pull_request_target and workflow_run running untrusted code, expression injection into run steps, missing or broad workflow permissions, third-party actions not pinned to a commit SHA, OIDC trust policies with wildcard subjects, self-hosted runners on public repos, secrets reaching forks, cache and artifact trust between workflows, and AI agents in CI that read issue or PR text while holding a write token. Runs zizmor and actionlint read-only and writes findings.json. Use when the user mentions 'pull_request_target,' 'pwn request,' 'workflow injection,' 'zizmor,' 'actionlint,' 'pin actions to SHA,' 'GITHUB_TOKEN permissions,' 'self-hosted runner,' 'claude-code-action,' 'AI agent in CI,' 'GitLab CI security,' 'CircleCI security,' 'is this workflow safe,' or needs to secure a build pipeline.

security-start

briiirussell/cybersecurity-skills/skills/security-start/SKILL.md

Start here when a security ask is vague and no specific skill fits yet. Asks two or three questions about what you have (source code, a live site, a cloud setup, logs, a suspicious file, an auditor's request) and what's going on (building, shipping, an active incident, a compliance deadline), then hands off to the right skill or skills from this catalog, in order. It does no auditing itself. Use when the user says things like 'make this secure,' 'is this secure,' 'where do I start with security,' 'which security skill should I use,' 'security checkup,' 'what do we check,' 'secure my startup,' or 'help me with security' without naming a framework, a target or a tool. If the ask already names one (OWASP, a CVE, a workflow file, SOC 2, a phishing email, a pasted finding), use that skill directly instead.

MaxMiksaSkill
