Use when working with mainframe systems, z/OS, JES2/JES3, VTAM, USS, or when users mention "mainframe", "z/OS", "MVS", "TSO", "ISPF", "JCL", "CICS", "IMS", "DB2 mainframe", "VSAM", "RACF", "mainframe modernization", "legacy mainframe", or "IBM z Systems".
bug-analysis
by DauQuangThanh
Analyzes software bugs including root cause identification, severity assessment, impact analysis, reproduction steps validation, and fix recommendations. Performs bug triage, categorization, duplicate detection, and regression analysis. Use when investigating bugs, analyzing crash reports, triaging issues, debugging problems, reviewing error logs, or when users mention "analyze bug", "investigate issue", "debug problem", "bug report", "crash analysis", "root cause analysis", or "fix recommendation".
vite-react-best-practices
by claudiocebpaz
Comprehensive React and Vite SPA performance, architecture, and deployment guidelines. Use this skill when building, reviewing, or refactoring React applications built with Vite (SPA). Covers Vite-specific build configurations, static hosting requirements, and core React performance patterns.
engineering-review-framework
by derKlinke
Structured pre-implementation engineering review for code writing, implementation planning, and architecture decisions. Use when drafting or reviewing plans before code changes, or when the user asks for rigorous analysis of architecture, code quality, testing, and performance with explicit tradeoffs, opinionated recommendations, and user checkpoints.
todo-tracker
by wubaiqing
Persistent TODO scratch pad for tracking tasks across sessions. Use when user says "add to TODO", "what's on the TODO", "mark X done", "show TODO list", "remove from TODO", or asks about pending tasks. Also triggers on heartbeat to remind about stale items.
memory-workflow
by VeriTeknik
"Guide the memory session lifecycle - start sessions, record observations, search memories, and end sessions with Z-reports. Use when working with Plugged.in memory system."
memory-forget
by VeriTeknik
"Delete specific memories or clear memory categories. Use with caution - forgotten memories cannot be recovered."
ios-auto-layout-debugging
by derKlinke
Use when encountering "Unable to simultaneously satisfy constraints" errors, constraint conflicts, ambiguous layout warnings, or views positioned incorrectly - systematic debugging workflow for Auto Layout issues in iOS
status
by VeriTeknik
"Check Plugged.in connection status, active session, and memory statistics"
memory-status
by VeriTeknik
"Show memory system status including active session, ring counts, and recent observations"
platform-tools
by VeriTeknik
"Complete reference for all Plugged.in MCP tools - memory, knowledge base, clipboard, documents, and notifications. Use when you need to know what tools are available."
vercel-react-best-practices
by Jst-Well-Dan
React and Next.js performance optimization guidelines from Vercel Engineering. This skill should be used when writing, reviewing, or refactoring React/Next.js code to ensure optimal performance patterns. Triggers on tasks involving React components, Next.js pages, data fetching, bundle optimization, or performance improvements.
Agent Memory Mcp

"A hybrid memory system that provides persistent, searchable knowledge management for AI agents (Architecture, Patterns, Decisions)."
performance-audit
by truongnat
Audit and optimize application performance across frontend, backend, and database layers. Identifies bottlenecks, provides actionable optimization recommendations, and measures improvements. Use when the app feels slow, Lighthouse scores are low, or API response times exceed targets.
agent-orchestration-improve-agent
by ngxtm
"Systematic improvement of existing agents through performance analysis, prompt engineering, and continuous iteration."
debugging-methodology
by webdevtodayjason
Scientific debugging methodology including hypothesis-driven debugging, bug reproduction, binary search debugging, stack trace analysis, logging strategies, and root cause analysis. Use when debugging errors, analyzing stack traces, investigating bugs, or troubleshooting performance issues.
Advisory Board Builder
by jmsktm
Recruit, structure, and manage advisory boards for strategic guidance
algorithm-complexity-analysis
by KentoShimizu
"Analyze candidate algorithms for time/space complexity, scalability limits, and resource-budget fit (CPU, memory, I/O, concurrency). Use when feasibility depends on input growth or latency/memory constraints and quantitative bounds are required before implementation; do not use for persistence schema or deployment topology decisions."
