AWSSkill

aws-security

aws/agent-toolkit-for-aws/plugins/aws-core/skills/aws-security/SKILL.md

AWS security service suitability, coverage and cost recommendations: WAF/origin overlap, AWS Network Firewall inspection coverage and policy review, VPC endpoint, Transit Gateway/Cloud WAN segmentation and DNS Firewall security-control suitability, certificate renewal ownership and monitoring, incident response triage ownership, centralized security log store (CloudWatch or Security Lake). Also factual configuration, findings, data sources and severity scoring for GuardDuty, Inspector, Security Hub V2/OCSF (Exposure, connectors, automation), Security Hub CSPM/ASFF (standards, controls), Macie, Detective, Security Lake, AWS Security Incident Response membership and case coverage, and Organizations security policies. Applies to advisory security-service choices even when one service is named. Implementation, rule or code authoring, deployment, scans and troubleshooting outside these factual procedures belong to specialist skills. Supports local AWS CLI and AWS MCP.

mizchiSkill

sql-security

mizchi/skills/sql-security/SKILL.md

SQL injection screening for host code (MoonBit / TS / Rust) plus secretlint setup notes. Flags single-line template-literal or string-concat SQL builders, regardless of value source — the scanner is line-based and does NOT trace data flow, so a clean scan is not proof of safety (multi-line template literals are missed) and every hit needs a manual review or an explicit `// sql-security: ok` opt-out.

zakirkun/deep-eye/.agents/skills/security-ops/SKILL.md

Router for Deep Eye agent skills: pentest, bug-bounty, red-team, blue-team, ctf. Use for security ops, mixed intent, offensive vs defensive choice.

tinyfish-ioSkill

dep-security

tinyfish-io/tinyfish-cookbook/skills/dep-security/SKILL.md

Check every dependency in a package.json against live CVE databases and security advisories in real time — specifically targeting vulnerabilities disclosed in the last 48 hours, the window that Snyk, Dependabot, and npm audit miss. Use this skill whenever a user mentions checking dependencies for vulnerabilities, wants to audit their package.json, asks about CVEs for their packages, says "are my dependencies safe", "check my packages for security issues", "any new vulnerabilities in my deps", or pastes a package.json and asks about security. Also trigger when a user mentions wanting fresher data than Snyk or Dependabot provides. Returns: which dependencies have brand-new vulnerabilities, severity, what the vulnerability does, whether a patched version exists yet, and a prioritised fix list.
