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.
-
ai-driven-dev Bundle 07 Refactor 2Improve code across four axes (cleanup, performance, security, architecture) by scanning and fixing, or applying a pushed audit report. Use when the user wants to refactor, optimize, harden, or remove code. Not for read-only diagnosis or adding tests.
-
ai-driven-dev Bundle Aidd Dev 03 Audit 2Perform deep codebase analysis to identify technical debt, dead code, and improvement opportunities.
-
ai-driven-dev Bundle Aidd Dev 06 Refactor 2Optimize code for performance and fix security vulnerabilities following OWASP guidelines.
-
ai-driven-dev Bundle Aidd Refine 03 Condense 2Toggle terse output mode with intensity levels (lite, full, ultra) so prose drops articles, filler, and pleasantries while code, quoted errors, and security warnings stay verbatim. Use when the user says "condense", "condense output", "be more concise", "shorter answers", "tighten output", "/condense", "/condense full", "/condense ultra", or "stop condense". Do NOT use for editing existing prose, summarizing a long document, or compressing source code (only output style is affected, not content).
-
stacksjs Skill Stacks Review 2Use when reviewing code changes in the Stacks project — two-pass code review with critical issue detection, test coverage audit, and auto-fix workflow. Invoke with /stacks-review.
-
stacksjs Skill Stacks Security 2Use when implementing security in Stacks — password hashing (bcrypt/argon2), app key generation, AES encryption/decryption, hash verification, rehashing detection, or security configuration (firewall, rate limiting, IP allowlists). Covers @stacksjs/security and config/security.ts.
-
jovanipink Bundle Prelaunch Readiness 2Audit whether a web property, service, application, or major relaunch is ready for public use, separating repository checks from provider and live-runtime evidence. Use for launch checklists, release readiness, and go or no-go reviews.
-
jovanipink Skill Code Change Review 2Review an exact code change for correctness, regressions, security, compatibility, test quality, and maintainability using the diff and repository evidence. Use before commit, pull request, merge, or release when the user wants findings rather than implementation.
-
jovanipink Skill Change Impact Analysis 2Analyze the blast radius of a proposed or completed change across callers, contracts, storage, jobs, clients, security, rollout, and operations. Use before review, merge, or release when downstream effects may be missed; do not substitute speculation for traced dependencies.
-
jovanipink Bundle Source Output Conformance Audit 2Audit whether exact source identity and expected values survive parsing or extraction, validation, persistence, and readback using source-cited oracles and mutation-sensitive tests. Use for end-to-end source-to-output fidelity claims; use test-quality-review for test-suite quality and authority-boundary-review for ownership architecture alone.
-
mrciphersmith Bundle Code Review 2Comprehensive code review with 4 parallel agents: correctness/logic, security, performance, style/maintainability. Produces unified severity report (CRITICAL/HIGH/MEDIUM/LOW). Use for thorough PR reviews and pre-merge checks.
-
mrciphersmith Bundle Review Performance 2Use when a performance review is requested, checking for N+1 queries, unnecessary re-renders, memory leaks, missing indexes, large bundle imports, and synchronous blocking in changed code. NOT for security, logic correctness, style, or architecture.
-
mrciphersmith Skill Review Style 2Use when: reviewing code for style, naming conventions, readability, and DRY violations — without touching logic, architecture, security, or performance. Covers "review style", "style review", "check naming", "check readability", or dispatched by review-orchestrator with --style flag. NOT for: logic bugs, architectural violations, security vulnerabilities, performance anti-patterns, or any finding that could cause a functional regression.
-
mrciphersmith Bundle Review Security Code 2Use when a code-level security review is requested, checking for injection vulnerabilities, auth gaps, insecure cryptography, secrets, and OWASP Top 10 patterns in changed code. NOT for infrastructure, deployment, or dependency audits.
-
stacksjs Skill Stacks Security Audit 2Use when performing security analysis on a Stacks application — OWASP Top 10, STRIDE threat modeling, attack surface mapping, dependency audit. Requires concrete exploit scenarios. Invoke with /stacks-security-audit.
-

-
keyvaluesoftwaresystems Skill Hld Interview 2Clarify material architecture decisions before an HLD is finalized. Generate feature-specific technical Grill questions, audit prior answers and contradictions, and collect grouped answers without drafting design prose.
-
keyvaluesoftwaresystems Skill Lld Interview 2Clarify only material repository implementation decisions before one repo LLD is written. Audit existing answers, inspect the bounded implementation seam, and ask feature-specific questions in grouped native popups.
-
keyvaluesoftwaresystems Skill Backend Review 2Review the backend implementation — security, contract adherence, correctness, backward compatibility, rate-limiting, performance/scaling, migrations, test gaps, observability. Read-only; writes a review artifact. Front door for /backend-review.
-
keyvaluesoftwaresystems Skill Backend Implement 2Implement an approved backend scope against the cross-repo contract, test-first, meeting the backend engineering standards (security, backward compatibility, rate limiting, idempotency, migrations, observability, performance). Edits code within the approved scope only. Front door for /backend-implement.
-
keyvaluesoftwaresystems Skill Postgres Patterns 2PostgreSQL database patterns for query optimization, schema design, indexing, and security. Based on Supabase best practices.
-
mrciphersmith Skill Review Clean Code 2Use when: reviewing code against Clean Code principles (Uncle Bob) and SOLID at the function/class level — meaningful names, small functions, single level of abstraction, argument count, error handling, DRY, comment quality, and SOLID (SRP, OCP, LSP, ISP, DIP) as applied to individual classes and functions. Triggered by: "review clean code", "check clean code", "Uncle Bob review", "SOLID review", "review --clean-code", or dispatched by review-orchestrator. NOT for: architectural layer violations (review-architecture), naming convention formatting (review-style), logic correctness bugs (review-logic), or security (review-security-code).
-
pixartseu Skill Hallmark 2Anti-AI-slop design skill with four explicit modes — build (new pages), audit (score existing UI against 57 slop-test gates), redesign (rebuild with a different fingerprint while preserving copy and IA), and study (extract design DNA from a URL or screenshot into a portable design.md). Use when the user says audit, redesign, or study, invokes Hallmark by name, or wants a greenfield page that does not look AI-generated. Includes 20 built-in themes and a pre-emit self-critique pass.
-
pixartseu Skill Taste Skill 2Aesthetic-direction design skill: reads a brief, infers the right visual style and direction, and ships interfaces that do not look templated. Umbrella for concrete style variants — minimalist, brutalist, soft/premium-agency. Use when the user wants a particular vibe or aesthetic, or wants a landing page or portfolio to feel handcrafted and expensive. For explicit build/audit/redesign/study modes use hallmark; for data-backed tokens use ui-ux-pro-max.
-
pixartseu Skill Test Master 2Generates test files, creates mocking strategies, analyzes code coverage, designs test architectures, and produces test plans and defect reports across functional, performance, and security testing disciplines. Use when writing unit tests, integration tests, or E2E tests; creating test strategies or automation frameworks; analyzing coverage gaps; performance testing with k6 or Artillery; security testing with OWASP methods; debugging flaky tests; or working on QA, regression, test automation, quality gates, shift-left testing, or test maintenance.
