Eval

This eval assumes the working directory is the root of the repository. Run it with:

cargo run -p eval

The eval will optionally read a .env file in crates/eval if you need it to set environment variables, such as API keys.

Explorer Tool

The explorer tool generates a self-contained HTML view from one or more thread JSON file. It provides a visual interface to explore the agent thread, including tool calls and results. See ./docs/explorer.md for more details.

Usage

cargo run -p eval --bin explorer -- --input <path-to-json-files> --output <output-html-path>

Example:

cargo run -p eval --bin explorer -- --input ./runs/2025-04-23_15-53-30/fastmcp_bugifx/*/last.messages.json --output /tmp/explorer.html
