Manage component registry for task categorization. List, find, and add components. State stored in .claude/state/task-streams/component-manager.json (gitignored). Auto-initializes with C00 "General / Cross-Cutting" on first use. Returns component codes like C01, C02. Use when user says 'list components', 'add component', 'find component', 'categorize tasks by component', or when organizing tasks by system module. (project, gitignored)

Expert knowledge for testing Composable Rust applications. Use when writing unit tests for reducers, setting up integration tests with real dependencies, using test utilities (TestStore, FixedClock, mocks), working with testcontainers for PostgreSQL/Redpanda, property-based testing, or questions about testing patterns and best practices.

Use this skill when implementing game UI addon interactions in SND macros. Covers crafting addons, shop addons, node access, and general game addon patterns.

Define custom Claude Code slash commands for agents in the Traycer enforcement framework. This skill should be used when creating or updating agents and needing to specify reusable prompts that agents can execute as slash commands. Commands are Markdown files stored in .claude/commands/ and referenced in agent config.yaml files. This is for Claude Code slash commands (/command-name), not bash/CLI commands.

PMC memory system for persistent context across sessions. Store, search,and retrieve project knowledge using semantic vector search (OpenAI embeddings)and full-text keyword search.Use when: storing important context, searching for past solutions,retrieving project-specific knowledge, or building up institutional memory.

File-based task management with shai-tix CLI. Use when user mentions kanban, ticket, planning, task tracking, or references tickets by [id] or #id format. MUST run via: uvx --from shai-tix==0.1.3 shai-tix <cmd>. Data stored in .tix/ directory (NOT .shai-tix/).

Guide for testing Firebase Admin SDK with Vitest mocks. Use when writing tests that involve Firebase Auth, Firestore, or Firebase App.

Optimize SvelteKit applications by leveraging SvelteKit's full-stack architecture for instant server-side rendering and progressive enhancement. Specialized in load functions, form actions, and SvelteKit's data loading patterns.Use when:- User reports slow initial page load with loading spinners- Page uses onMount + fetch for data fetching- Store patterns cause waterfall fetching- Need to improve SEO (content not in initial HTML)- Converting client-side data fetching to server-side load functions- Implementing progressive enhancement patternsTriggers: "slow loading", "optimize fetching", "SSR data", "SvelteKit optimization","remove loading spinner", "server-side fetch", "convert to load function", "progressive enhancement","data fetch lambat", "loading lama"

Store project-specific insights and context into file-based memory. Use after completing tasks that reveal important details about THIS codebase. Use when user says "--project-store" or "--learn" (you decide which scope, may use both) or after discovering project-specific patterns. Skip for universal patterns (use coder-memory-store) or routine work.

Store and export type constraints for Type::Tiny, Moose, Data::Checks, and more

This skill should be used when the user asks to "store context", "save decisions", "persist information", "document patterns", "share across sessions", or needs best practices for Serena memory management for cross-session context persistence and knowledge storage.

Use when creating Svelte components, SvelteKit applications, implementing reactive patterns, handling state management, working with stores, transitions, animations, or any Svelte/SvelteKit development task. Includes comprehensive documentation access, code validation with svelte-autofixer, and playground link generation.

Implement comprehensive validation using Zod schemas for type-safe validation on both client and server, with server-side validation as the security boundary (never trust client input). Use this skill when validating user inputs, creating API endpoints that accept data, implementing forms, defining data schemas, validating file uploads, creating validation middleware, implementing Firestore security rules or Supabase RLS, or writing validation rules for any user-provided data. Apply when working on API route handlers, form components with React Hook Form, validation middleware, Zod schema definitions (schemas/*.ts, validation/*.ts), Firestore security rules (firestore.rules), Supabase RLS policies, or any code that accepts external input. This skill ensures server-side validation always (client-side is for UX only), Zod for schema validation with TypeScript type inference (z.infer<typeof schema>), validation middleware factory for Express/Bun APIs, React Hook Form + zodResolver for forms, user-friendly error
