Skills for your AI
AI skills for IT & software development
Site architecture
Plan or restructure website hierarchy, navigation, URL patterns, breadcrumbs, and internal linking. Use when mapping pages, sections, and site structure, but not for XML sitemap auditing or schema markup.
Skill audit
Pre-install security scanner for AI agent skills. 7.5% of 14,706 skills are malicious. Audit before you trust.
Skill check
Validate Claude Code skills against the agentskills specification. Catches structural, semantic, and naming issues before users do.
Skill security audit
Audit an Agent Skill, MCP server, connector, or desktop extension before installation by tracing code, dependencies, permissions, credentials, data flow, and irreversible actions.
Slack bot builder
Build Slack apps using the Bolt framework across Python, JavaScript, and Java. Covers Block Kit for rich UIs, interactive components, slash commands, event handling, OAuth installation flows, and Workflow Builder integration.
Slo implementation
Framework for defining and implementing Service Level Indicators (SLIs), Service Level Objectives (SLOs), and error budgets.
Smartui skill
Generates SmartUI visual regression test configurations for screenshot comparison on TestMu AI cloud. Framework-agnostic — works with Playwright, Selenium, Cypress, Puppeteer. Use when user mentions "SmartUI", "visual regression", "screenshot comparison", "vis
Smtp penetration testing
Conduct comprehensive security assessments of SMTP (Simple Mail Transfer Protocol) servers to identify vulnerabilities including open relays, user enumeration, weak authentication, and misconfiguration.
Software architecture
Guide for quality focused software architecture. This skill should be used when users want to write code, design architecture, analyze code, in any case that relates to software development.
Solidity security
Master smart contract security best practices, vulnerability prevention, and secure Solidity development patterns.
Source driven development
Grounds every implementation decision in official documentation. Use when you want authoritative, source-cited code free from outdated patterns. Use when building with any framework or library where correctness matters.
Spec driven loop
Freeze PRD, technical design, and acceptance criteria before medium-to-large Codex work; coordinate agents with explicit ownership, then judge delivery from diffs, tests, and evidence.
Spec to code compliance
Verifies code implements exactly what documentation specifies for blockchain audits. Use when comparing code against whitepapers, finding gaps between specs and implementation, or performing compliance checks for protocol implementations.
Speckit updater
This skill provides safe update capabilities for GitHub SpecKit installations, preserving customizations while applying template updates.
Spline 3d integration
Use when adding interactive 3D scenes from Spline.design to web projects, including React embedding and runtime control API.
Sql injection testing
Execute comprehensive SQL injection vulnerability assessments on web applications to identify database security flaws, demonstrate exploitation techniques, and validate input sanitization mechanisms.
Sql optimization patterns
Diagnose slow SQL with query plans, preserve query results, and verify indexing or query changes against representative data.
Sqlmap database pentesting
Provide systematic methodologies for automated SQL injection detection and exploitation using SQLMap.
Square automation
Automate Square tasks via Rube MCP (Composio): payments, orders, invoices, locations. Always search tools first for current schemas.
Squirrel
Full-cycle AI coding skill: plans, builds, tests, lints, fixes bugs, and writes production-grade docs. Auto-detects project state and adapts its 8-phase pipeline.
Ssh penetration testing
Conduct comprehensive SSH security assessments including enumeration, credential attacks, vulnerability exploitation, tunneling techniques, and post-exploitation activities. This skill covers the complete methodology for testing SSH service security.
Sshepherd
Zero-knowledge SSH ops CLI — server health checks, docker/systemd control, log tailing, Postgres introspection, and declarative deploys, without ever exposing credentials to the agent.
Stitch design taste
Use when generating Google Stitch DESIGN.md systems for premium typography, color, layout, motion intent, and anti-generic UI rules.
