Time and timezone utilities for getting current time and converting between timezones. Use when: (1) Getting current time in any timezone, (2) Converting time between different timezones, (3) Working with IANA timezone names, (4) Scheduling across timezones, (5) Time-sensitive operations. Triggers: "what time is it", "current time", "convert time", "timezone", "time in [city]".

Multi-step reasoning engine for complex analysis and systematic problem solving. Use when: (1) Complex debugging scenarios with multiple layers, (2) Architectural analysis and system design, (3) Problems requiring hypothesis testing and validation, (4) Multi-component failure investigation, (5) Performance bottleneck identification. Triggers: "--think", "--think-hard", "--ultrathink", "analyze step by step", "break down this problem", "systematic analysis". IMPORTANT: Do NOT use for simple single-step tasks.

Semantic codebase search, code indexing, and prompt enhancement via standalone CLI. Use when: (1) Semantic code search with natural language queries, (2) Code indexing for remote codebase retrieval, (3) Prompt enhancement with codebase context, (4) Before grep/find/glob operations for better accuracy, (5) Complex requirements clarification, (6) Large codebase navigation. Triggers: "search context", "enhance prompt", "find code that", "index project", "clarify requirements". IMPORTANT: Always use ace-tool BEFORE grep/find/glob for semantic-level code location.

Iteratively inspect and polish connected Google Slides presentations in Codex using slide thumbnails plus raw Slides edits. Use when a user asks to fix spacing, alignment, overlap, crowding, hierarchy, or deck-wide visual consistency in Google Slides, especially when the work should follow a thumbnail -> diagnose -> batch_update -> re-thumbnail verification loop.

Implement 2D browser games with Phaser, TypeScript, and Vite. Use when the user wants the default 2D path for gameplay systems, scenes, cameras, sprite animation, HUD integration, and browser-friendly game structure.

Generate and normalize 2D sprite animations for browser games. Use when the user wants sprite sheets, animated strips, consistent character frames, or a repeatable workflow for turning one approved frame into a production-ready animation candidate.

Build 3D browser games with a concrete vanilla Three.js stack. Use when the user wants plain TypeScript or Vite control over Three.js scenes, loaders, physics, GLB assets, materials, WebGL debugging, and a clean low-chrome 3D scaffold without a React wrapper.

Use when the user wants to review unread activity, distill long threads, prepare status updates, reply in the right tone, or translate notes into Slack-ready message formatting.

Migrate an existing connected Google Slides deck onto a company or team template in Codex. Use when a user wants to restyle a deck to match a template, port content from a source presentation into a branded template deck, or rebuild slides by duplicating template patterns rather than patching the old layout in place.

Triage Outlook inboxes, summarize email threads, extract action items, and draft replies or forwards through connected Outlook data. Use when the user wants to inspect a mailbox or thread, understand the latest status, identify what still needs a response, or prepare a safe draft without sending it by default.

Create and scaffold plugin directories for Codex with a required `.codex-plugin/plugin.json`, optional plugin folders/files, and baseline placeholders you can edit before publishing or testing. Use when Codex needs to create a new local plugin, add optional plugin structure, or generate or update repo-root `.agents/plugins/marketplace.json` entries for plugin ordering and availability metadata.

Build React-hosted 3D browser games with React Three Fiber and the pmndrs stack. Use when the user wants a 3D scene inside a React app, declarative scene composition, shared app state, or React-native UI coordination around a clean low-chrome 3D experience.

Import customer or external RDF/OWL into this repo's catalogue format. Use when user drops an RDF/OWL file and wants it catalogue-ready (metadata, category, validation, compile).

Generate Ontology School course paths/labs with progressive step ontologies from source ontology material. Use when user asks to tutorialize an ontology into school lessons and per-step builds.
