breakdown
★ 3Break down a PRD into self-contained implementation tasks for LLM execution. Use when you have a PRD file and want to generate executable task files for autonomous implementation.
subcodex
★ 3Collaborate with Codex (GPT-5.2) via named sessions. Trigger: user asks to work with Codex, use Codex, ask Codex, involve Codex, etc.CRITICAL: Use subcodex CLI via Bash, NOT the Task subagent tool.
parking-lot
★ 3Fast, non-poisoning synchronization primitives
codebase-analyzer
★ 3Analyze implementation details, trace data flow, and explain technical workings with precise file:line references. Use this when you need to understand HOW code works in the existing codebase.
gitinjest
★ 3Convert GitHub repositories into LLM-friendly text. Use when you need to analyze external codebases, research unfamiliar libraries, understand third-party project structure, or ingest code from GitHub URLs (public/private, supports subdirectories).
codex-skill
★ 3Use when user asks to leverage codex, gpt-5, or gpt-5.1 to implement something (usually implement a plan or feature designed by Claude). Provides non-interactive automation mode for hands-off task execution without approval prompts.
rr-solidity
★ 3Comprehensive Solidity smart contract development skill using Foundry framework. Use for writing, testing, deploying, and auditing Solidity contracts with security-first practices. Also triggers when working with .sol files, Foundry project files (foundry.toml), test files (.t.sol), or smart contract deployment scripts. Example triggers: "Write smart contract", "Create Solidity test", "Deploy contract", "Audit smart contract", "Fix security vulnerability", "Write Foundry test", "Set up Foundry project"
speech-to-text
★ 3Expert skill for implementing speech-to-text with Faster Whisper. Covers audio processing, transcription optimization, privacy protection, and secure handling of voice data for JARVIS voice assistant.
idaes
★ 3Comprehensive guidance for using IDAES (Institute for the Design of Advanced Energy Systems)for process systems engineering. Covers flowsheet modeling, property packages, unit models,optimization, scaling, initialization, and diagnostics. Use when working with chemical processsimulations, energy systems modeling, power plant design, material and energy balances, orprocess optimization. Triggers include 'IDAES', 'flowsheet', 'process model', 'unit operation','process optimization', 'property package', 'energy systems', or process engineering tasks.
opentrons-heater-shaker
★ 3Opentrons Heater-Shaker Module - temperature control (37-95°C) with orbital mixing (200-3000 rpm) for cell culture, enzymatic reactions, and sample preparation requiring simultaneous heating and agitation
hooks-builder
★ 3Create event-driven hooks for Claude Code automation. Use when the user wants to create hooks, automate tool validation, add pre/post processing, enforce security policies, or configure settings.json hooks. Triggers: create hook, build hook, PreToolUse, PostToolUse, event automation, tool validation, security hook
performance-analysis-and-optimization
★ 3CPU profiling, benchmarking, and memory analysis for Rust applications. Use when code is slow, memory usage is high, or optimization is needed.
python-env
★ 3Fast Python environment management with uv (10-100x faster than pip). Triggers on: uv, venv, pip, pyproject, python environment, install package, dependencies.
file-search
★ 3Modern file and content search using fd, ripgrep (rg), and fzf. Triggers on: fd, ripgrep, rg, find files, search code, fzf, fuzzy find, search codebase.
creating-slash-commands
★ 3Build custom slash commands in Claude Code with YAML frontmatter, permissions, and best practices. Use when creating automation workflows, project-specific commands, or standardizing repetitive tasks.
agent
★ 3Build LLM agents using `tdx agent pull/push` with YAML/Markdown config. Covers agent.yml structure, tools (knowledge_base, agent, web_search, image_gen), @ref syntax, and knowledge bases. Use for TD AI agent development workflow.
