Development

UI theme system, design tokens, Material-UI patterns, and accessibility standards. Handles theme customization, component styling, design system patterns, and accessibility features. Use when working with UI components, theme customization, design system patterns, or accessibility features, or when user mentions Material-UI, MUI components, theme tokens, dark mode, component styling, design system, accessibility, layout issues, styling problems, or ARIA patterns.

Context Struct Pattern (C-Specific) pattern for C development

Web scraping spiders (Scrapy), parsers, and source management.

Save session context to disk for seamless continuation in new chat sessions. This skill should be used when the user asks to save context, preserve work state, checkpoint progress, or prepare for session handoff. Triggers on "save context", "checkpoint", "save progress", "preserve state", or when explicitly asked to create a context file for later resumption. Optimizes for correctness, completeness, minimal size, and trajectory preservation.

Restore previous session state from Serena MCP checkpoints. Retrieves checkpoint by ID or auto-selects most recent, deserializes context, restores command/skill/phase/wave state. Use when: resuming after context loss, continuing previous session, recovering from interruption.

Automatically save and restore development context to minimize cognitive load when resuming work. Use when switching tasks, taking breaks, or returning after interruptions. Captures mental state, file locations, and next steps. Designed for ADHD developers with high context-switching costs.

Execute context preservation protocols for session continuity.

Waypoint plans methodology and session survival patterns for Claude Code. Use when working on long-running features, need to resume after context reset, want to document task progress, or need to survive session interruptions. Covers three-file structure (plan/context/tasks), SESSION PROGRESS tracking, quick resume instructions, update frequency, and context handoff patterns.

Keep development token use low by refreshing and relying on local context packs.

Automatically optimizes context window usage when filling up (>70%). Uses hierarchical summarization, selective file loading, and intelligent compaction to maintain conversation quality while reducing token count by 60-80%. Proactively activates to prevent context overflow.

Bootstrap, maintain, and evolve context networks across their full lifecycle. Use when starting a new project, when existing documentation feels scattered, or when agent effectiveness degrades due to missing context.

Proactive context window management via token monitoring, intelligent extraction, and selective rehydration. Use when approaching token limits or needing to preserve essential context. Complements /transcripts and PreCompact hook with proactive optimization.

Explains how SpecWeave achieves context efficiency through Claude's native progressive disclosure and sub-agent parallelization. Use when asking about token usage, context management, or how SpecWeave scales with large projects. Leverages Claude's built-in mechanisms without custom caching.

Create concise handover summary for seamless continuation in new chat session

Load relevant design documents and project context before working on any task. Use when user asks about features, requests implementation, discusses functionality, analyzes architecture, updates documentation, or mentions specific components like OAuth, authentication, Logto, sync, Happy Server, messaging, chat, terminal, command, zen mode, boxes, workspace. Ensures all work is grounded in documented design decisions. Prevents assumptions and misaligned solutions by loading context first.

Specifies rules for managing context files, including the master project context and supplementary files, emphasizing stability and change management.

Hybrid semantic/lexical code search with neural reranking via MCP tools. Use when searching a codebase, finding implementations, understanding how code works, finding callers/definitions, searching git history, or storing/retrieving knowledge. IMPORTANT - Always prefer these MCP tools over grep/find/cat for code exploration.

This skill should be used when the user asks to "build background agent", "create hosted coding agent", "set up sandboxed execution", "implement multiplayer agent", or mentions background agents, sandboxed VMs, agent infrastructure, Modal sandboxes, self-spawning agents, or remote coding environments.

This skill should be used when the user asks to "offload context to files", "implement dynamic context discovery", "use filesystem for agent memory", "reduce context window bloat", or mentions file-based context management, tool output persistence, agent scratch pads, or just-in-time context loading.

Optimize Claude Code context window usage. Identify what to keep in context vs fetch on-demand. Use when context is bloated, responses are slow, hitting token limits, or want to slim down context.

Automatically detect project tech stack, frameworks, and development context

Claude Code-optimized context transfer for development workflows. Preserves code context, git state, running services, and development environment when moving work between sessions. Works seamlessly with peer review skills (Codex/Gemini). Use when transferring development work to a new Claude Code session.

Context compression and summarization methodology. Techniques for reducing token usage while preserving decision-critical information.

Systematic codebase investigation before addressing issues. Use when you need to build comprehensive understanding of a problem area.
