Security
Security agent skills give AI agents disciplined security workflows: code review for vulnerabilities, secret handling, dependency audits, and hardening checklists. Every skill on SkillMD also passes its own safety review before listing, with capability flags shown on each page.
-
goldenwing-360 Skill Android SecurityHarden Android apps against the platform-specific failure modes. Covers Android Keystore and StrongBox, encrypted local storage, network security config and certificate pinning, WebView hardening, exported components and intent hijacking, backup rules, and Play Integrity with root detection as a signal. Invoke when shipping an Android app that holds credentials or tokens, before Play Store submission, or after a mobile security advisory.
-
goldenwing-360 Skill Dns Domain SecuritySecure the DNS and domain layer below TLS — the records, registrar, and provider access everyone forgets. Covers dangling records and subdomain takeover, registrar hardening and transfer locks, CAA, DNSSEC trade-offs, zone hygiene, split-horizon leakage, scoped DNS API tokens, and CT-log monitoring. Invoke when auditing a zone, when a domain or registrar account changes hands, or after decommissioning a SaaS service a CNAME pointed at.
-
goldenwing-360 Skill Object Storage SecuritySecure object storage buckets on S3, Cloudflare R2, GCS, and MinIO against public exposure and credential abuse. Covers public access audit, bucket policy vs ACL vs IAM, presigned URLs with scoped credentials, CORS for direct browser upload, encryption choices, versioning and object lock, and access logging. Invoke when creating a new bucket, auditing inherited buckets for exposure, or wiring an app to storage with presigned uploads.

mrgoonie Skill RepomixGuide for using Repomix - a powerful tool that packs entire repositories into single, AI-friendly files. Use when packaging codebases for AI analysis, generating context for LLMs, creating codebase snapshots, analyzing third-party libraries, or preparing repositories for security audits.
-
mr-graphnstaff Bundle Secarch Weekly StatusManage HUB Security Architecture weekly status reports in Confluence and Word. Use for `WSR-now`, `WSR-now-config`, `WSR-export`, or requests to create, update, or export the weekly report.
-
peytonli Bundle Review ArchitectureUse when you need a complete top-down architecture audit of any codebase, including full exploration of major paths, endpoint mapping, current-vs-target user journeys from documentation, and deep issue remediation plans with step-by-step fixes. Trigger phrases: architecture audit, full codebase walkthrough, map all endpoints, user journey analysis, current vs desired product flow, find and fix project issues, end-to-end architecture review.
-
ruslanamandell Bundle Unslop FixApply remediations from an unslop audit report. Fixes mechanically safe issues automatically on a dedicated branch with one commit per finding, proposes patches for issues that need a single human decision, and lists the credential rotations and dashboard changes that only a person can perform. Use after unslop-audit, or when the user asks to fix, remediate, harden, or clean up the findings from a codebase audit.
-
ruslanamandell Bundle Unslop AuditAudit a codebase for the production failures typical of AI-generated software - hardcoded secrets, disabled row level security, IDOR and missing authorization, unvalidated inputs, missing error handling and rate limits, N+1 queries and unindexed columns, hallucinated dependencies, duplicated patch-on-patch code, and missing tests or version control. Use when the user asks to audit, review, harden, or production-check a codebase, mentions vibe coding cleanup, asks "is this safe to ship", or is preparing an AI-built app for real users. Read-only - never edits code.
-
ruslanamandell Bundle Unslop GuardInstall and run pre-ship guardrails that stop new AI-generated slop from re-entering a codebase - a warn-only pre-commit hook that blocks only on secrets, and a GitHub Actions workflow that runs the unslop audit on pull requests and fails on critical findings. Use when the user asks to prevent regressions, add a pre-commit or CI security check, or gate deploys on an audit.
-
skillmedev Skill Regulatory ScannerMaps which regulations apply to a product or business across every operating jurisdiction, translates them into concrete obligations, and produces a prioritized compliance-gap table. Use when someone asks "what regulations apply to my product", "are we GDPR or CCPA exposed", "run a compliance gap analysis", or is entering a new market or handling a new data type. Do NOT use for drafting the legal documents themselves - use terms-of-service instead. Do NOT use for assembling SOC 2 audit evidence - use soc2-evidence-helper instead. Do NOT use for patent landscape questions - use patent-prior-art instead.
-
tgpski Bundle Fips Finding TriageClassifies an individual FIPS crypto audit finding as real cryptography or a non-cryptographic use of a crypto primitive, using structured diagnostic reasoning. Follows the abductive triage methodology of resolving coordinate mismatches first, since most findings are non-crypto, then tracing data flow and protocol requirements only when a usage is genuinely ambiguous. Use when an audit surfaces a CRITICAL or WARNING finding that needs classification, when a vendored dependency's crypto usage may not ship in the binary, or when producing evidence for a compliance review.
-
inetgas Skill Compiling ArchitectureUse when: user wants to select architecture patterns, compile a spec, iterate on constraints/NFRs, audit why patterns were selected/rejected, or finalise an architecture for implementation. Not when: no repeatable decisions needed, or constraints/NFRs are not yet known (gather those first).
-
jgsystemsconsulting Skill Spec ReviewAutonomously harden an engineering specification through a roundtable of independent engineering-discipline reviewers (architecture, security, test/QA, operations, product). Each reviewer is a real subagent thinking independently; the orchestrator collects findings, revises the spec itself, and loops until convergence (no CRITICAL or MAJOR findings) with NO user checkpoints. Use when you say "review this spec", "harden this spec", "spec review", "run the roundtable on this spec", or want a spec battle-tested before implementation. Self-contained, with no dependency on any other skill.

-
kylezantos Bundle Thumb FirstOne-stop mobile review — the umbrella for the thumb-first suite. Runs a design-judgment pass AND a platform-technical pass over a mobile app/screen/PWA, then merges them into ONE prioritized report that keeps design forks (opinions) and platform defects (objective, P0–P3) visually distinct. Use when the user wants to review, audit, critique, or design a mobile app, screen, or PWA — 'review my mobile app', 'is this good mobile UX', 'audit this screen', 'check my PWA'. Routes to: full review (default), design-only (thumb-first-design), or platform-only (thumb-first-platform). Platform-agnostic on judgment; web/PWA-deep on technical, with native handoff.
-
kylezantos Bundle Thumb First DesignThe design-judgment layer of the thumb-first mobile suite — decides WHAT the right mobile pattern is and WHY, platform-agnostic across web and native. Reasons through named designer lenses (Hoober, Hurff, Wroblewski, Clark, Rausch, Budiu, Allen, de With, Nelson) with context-aware weighting, and surfaces decision forks where there's no single right answer. Two modes: plan a feature's mobile design before code, or audit an existing one. Use for navigation-pattern choices (tab bar, drawer, bottom sheet), thumb-reach and action placement, mobile forms, gestures vs visible controls, and mobile design critique — or when the user mentions mobile design, mobile UX, thumb zones, one-handed use, bottom sheets, or mobile navigation. Usually run via the /thumb-first umbrella (which also runs platform checks); invoke directly for design judgment only. For web/PWA technical defects use thumb-first-platform.

lee-miya Skill Kbs Weekly UpdateRuns the KBS Monday weekly update: KEV/N-day, AI audit case studies, CTF tricks, EDR, phishing, perimeter devices, and third-party offensive skill library changelogs (Claude-Red, Claude-BugHunter, Claude-OSINT). Use when the user asks for 周更, 每周情报, weekly intel, or to scan similar GitHub skill repos. Follows 维护/每周更新SOP.md and never copies exploit payloads from third-party skills into the repo.
-
ailabs-393 Bundle Tech Debt AnalyzerThis skill should be used when analyzing technical debt in a codebase, documenting code quality issues, creating technical debt registers, or assessing code maintainability.

-
litsec Skill Maven Dependency UpdaterKeep Maven POM files up to date by checking and upgrading all dependencies and plugins to their latest versions. Use this skill whenever the user mentions updating, bumping, upgrading, or checking Maven dependencies or plugins — even if they just say "update my POMs", "are my dependencies up to date?", "bump versions", or "check for newer versions". Trigger also when the user shares or references a pom.xml and asks about version currency. Handles multi-module Maven projects, asks before applying major version upgrades, and keeps a clear audit trail of every change made.
-
coreeng Bundle Doc JourneysUse when consolidating, generating or refreshing product and journey documentation in a static documentation site from documentation scattered across many source repositories. Reads the consumer repository's `.doc-settings/` and product definition, discovers relevant material across the source repos, and rewrites it into Diátaxis-typed pages under the configured output root, never authoring from scratch — every claim traces to prose that already existed, code and manifests corroborate but are never written from, and material that exists only as code is reported as a gap. Journeys spanning several products are published to their own section, routing readers to the product documentation rather than restating it. Every page carries a computed confidence score. Also refreshes docs it wrote previously — detecting whether sources actually changed, protecting human-edited pages, regenerating minimally — plus a legacy `audit` mode that classifies existing documentation in a single repo without writing.
-
crafter-station Skill CoreManage Spaceship domains, DNS, contacts, transfers, marketplace listings and Hyperlift apps from the command line. Use when the user mentions Spaceship, asks about their domains, wants to check what is expiring, edit DNS records, transfer a domain in, list a domain for sale, or audit a domain portfolio for risk. Covers all 50 operations of the Spaceship public API.
-
crafter-station Skill PortfolioAudit and operate a whole Spaceship domain portfolio at once: find what is expiring, what lost its transfer lock, what is suspended, and what is past expiry but still recoverable. Use when the user asks about many domains rather than one, wants a sweep before a renewal cycle, asks what needs attention, or wants to apply the same change across a set of domains without hitting the API's per-domain rate limit.
-
crafter-station Skill SpaceshipManage Spaceship domains, DNS, contacts, transfers, marketplace listings and Hyperlift apps from the command line. Use when the user mentions Spaceship, asks about their domains, wants to check what is expiring or what needs attention, edit DNS records, transfer a domain in, register or renew a domain, list one for sale, or audit a whole domain portfolio for risk. Covers all 50 operations of the Spaceship public API, with a trust ladder so writes need explicit approval.

mastra-ai Skill Extend Smoke CoverageAdd smoke-test coverage for a new Mastra feature, API route, or Studio UI surface. Use when the user asks to "add coverage for X", "write a smoke test for the new Y endpoint", "test the new Z page", when a Mastra release notes mention features not currently exercised, when investigating a regression that wasn't caught because there was no test for that path, or any time you are about to write or modify a `.test.ts` / `.spec.ts` file under `tests/` or `tests-ui/`. This skill explains where tests live (`tests/` API vs `tests-ui/` UI), how to register fixtures in `src/mastra/`, how to update the COVERAGE.md tracking docs so the suite reflects reality, the assertion patterns that are banned because they pass against garbage data, and the self-audit pass to run before committing.

maxbuildog Bundle AI Answer AuditMeasures whether any website can be found and cited by AI assistants, and reports why not. Runs deterministic checks on AI crawler access, structured data, server-rendered content and answer-shaped structure, then probes real audience questions through search to see who gets cited instead. Triggers: "why doesn't ChatGPT cite my site", "GEO audit", "AEO audit", "answer engine optimization", "generative engine optimization", "am I visible to AI", "are we in AI Overviews", "should I add llms.txt", "am I blocking GPTBot", "my competitor gets cited and I don't", "is my site AI search ready", "does Perplexity know my site". Not for Shopify product-level audits with store prevalence (use shopify-geo-audit), and not for classic Google ranking or rich results.
-
