Who it is forA developer or analyst who needs a multi-step research answer and is willing to install a Python tool.

The problemDoing multi-step research by hand across many sources takes time, and a single chat prompt rarely covers it.

The outcomeA running Poirot session that answers a research question in the TUI conversation view.

What you need first

  • Python 3.12 or newer
  • A DeepSeek API key (the README says to set DEEPSEEK_API_KEY in .env)
  • Git and a terminal
  • Docker only if you want the container sandbox

Steps

  1. Clone the repo from https://github.com/HezaoHezao/poirot and change into the project folder. (inferred, check the README)
  2. Create a virtual environment with python -m venv .venv.
  3. Activate it with source .venv/bin/activate on Linux or macOS, or .venv\Scripts\activate on Windows.
  4. Install the project with pip install -e ".[dev]".
  5. Copy the sample config with cp .env.example .env and set DEEPSEEK_API_KEY in .env.
  6. Start Poirot with poirot and type your research question.

Prompt for your agent

Using the Poirot repo at <path to poirot checkout>, create a virtual environment, install it, set DEEPSEEK_API_KEY in .env, and launch `poirot` with the research question <research question>. Expected output: a research answer shown in the TUI conversation view. Verify that the status bar shows live token usage.

Caveat. The README says the default launch is the TUI and points to USAGE.md for full configuration and troubleshooting, so check that file if setup fails.
