clawd-throttle
Automatically routes LLM requests to the cheapest capable model based on prompt complexity. Classifies prompts on 8 dimensions in under 1ms, supports 8 providers and 27+ models across three routing modes (eco, standard, performance). Works as both an MCP server and an HTTP reverse proxy compatible with any OpenAI/Anthropic client.

About this skill
Clawd Throttle
Route every LLM request to the cheapest model that can handle it. Stop paying Opus prices for "hello" and "summarize this."
Supports 8 providers and 25+ models: Anthropic (Claude), Google (Gemini), OpenAI (GPT / o-series), xAI (Grok), DeepSeek, Moonshot (Kimi), Mistral, and Ollama (local).
How It Works
- Your prompt arrives
- The classifier scores it on 8 dimensions (token count, code presence, reasoning markers, simplicity indicators, multi-step patterns, question count, system prompt complexity, conversation depth) in under 1 millisecond
- The router maps the resulting tier (simple / standard / complex) to a model based on your active mode and configured providers
- The request is proxied to the correct API
- The routing decision and cost are logged to a local JSONL file
Routing Modes
| Mode | Simple | Standard | Complex |
|---|---|---|---|
| eco | Grok 4.1 Fast | Gemini Flash | Haiku |
| standard | Grok 4.1 Fast | Haiku | Sonnet |
| gigachad | Haiku | Sonnet | Opus 4.6 |
Each cell shows the first-choice model. The router tries a preference list and falls through to the next available provider if the first is not configured.
Available Commands
| Command | What It Does |
|---|---|
route_request | Send a prompt and get a response from the cheapest capable model |
classify_prompt | Analyze prompt complexity without making an LLM call |
get_routing_stats | View cost savings and model distribution stats |
get_config | View current configuration (keys redacted) |
set_mode | Change routing mode at runtime |
get_recent_routing_log | Inspect recent routing decisions |
Overrides
- Heartbeats and summaries always route to the cheapest model
- Type
/opus,/sonnet,/haiku,/flash, or/grok-fastto force a specific model - Sub-agent calls automatically step down one tier from their parent
Setup
- Get at least one API key (Anthropic or Google required; others optional):
- Anthropic: https://console.anthropic.com/settings/keys
- Google AI: https://aistudio.google.com/app/apikey
- xAI: https://console.x.ai
- OpenAI: https://platform.openai.com/api-keys
- DeepSeek: https://platform.deepseek.com
- Moonshot: https://platform.moonshot.cn
- Mistral: https://console.mistral.ai
- Run the setup script:
npm run setup - Choose your routing mode (eco / standard / gigachad)
Privacy
- Prompt content is never stored. Only a SHA-256 hash is logged.
- All data stays local in ~/.config/clawd-throttle/
- API keys stored in your local config file

Use this skill when users ask to create flowcharts, swimlane diagrams, cross-functional flowcharts, org charts, network diagrams, UML diagrams, BPMN, project management diagrams (WBS, Gantt, PERT, RACI), risk matrices, stakeholder maps, or any other visual diagram in draw.io format. This skill includes access to custom shape libraries for icons, clipart, and professional symbols.
pdf-to-markdown
aliceisjustplaying
Convert entire PDF documents to clean, structured Markdown for full context loading. Use this skill when the user wants to extract ALL text from a PDF into context (not grep/search), when discussing or analyzing PDF content in full, when the user mentions "load the whole PDF", "bring the PDF into context", "read the entire PDF", or when partial extraction/grepping would miss important context. This is the preferred method for PDF text extraction over page-by-page or grep approaches.
godot

This skill should be used when working on Godot Engine projects. It provides specialized knowledge of Godot's file formats (.gd, .tscn, .tres), architecture patterns (component-based, signal-driven, resource-based), common pitfalls, validation tools, code templates, and CLI workflows. The `godot` command is available for running the game, validating scripts, importing resources, and exporting builds. Use this skill for tasks involving Godot game development, debugging scene/resource files, implementing game systems, or creating new Godot components.
nano-banana-pro
garg-aayush
Generate and edit images using Google's Nano Banana Pro (Gemini 3 Pro Image) API. Use when the user asks to generate, create, edit, modify, change, alter, or update images. Also use when user references an existing image file and asks to modify it in any way (e.g., "modify this image", "change the background", "replace X with Y"). Supports both text-to-image generation and image-to-image editing with configurable resolution (1K default, 2K, or 4K for high resolution). DO NOT read the image file first - use this skill directly with the --input-image parameter.
