Tool-Using Agent 🛠️

Ask a question and watch the AI call real, live tools to answer it — a calculator, the current date/time, live weather, and Wikipedia — running the ReAct loop (decide → call a tool → read the result → repeat) and showing every tool call it made.

Project #9 of my "30 AI Projects in 15 Days" build-in-public challenge.

Try

• —"What's a 15% tip on $47.80, and what's the weather in Paris?" → calculator + weather
• —"Who invented the World Wide Web, and how many days ago was Jan 1 2000?" → Wikipedia + date + calc

How it works

• —The model is given four keyless tools (Open-Meteo for weather, MediaWiki for Wikipedia, plus a safe calculator and a clock). It decides which to call — possibly several — and the server executes them and feeds results back, looping until the model can answer (capped at a few steps).
• —Transparency: the UI shows the exact tool calls and their live results, so you can see the reasoning, not just the answer.
• —The calculator is a safe AST evaluator (no eval), limited to arithmetic + a few math functions.

Run locally

pip install -r requirements.txt
export ANTHROPIC_API_KEY=sk-ant-...
python app.py                            # http://127.0.0.1:7860

Deploy (always-on)

Ships with a Dockerfile — works on Hugging Face Spaces, Render, Railway, or Fly.io. Set ANTHROPIC_API_KEY as a secret. The tools need no other keys.
