# Explorer Threads Explorer is a single self-contained HTML file that gives an overview of evaluation runs, while allowing for some interactivity. When you open a file, it gives you a _thread overview_, which looks like this: | Turn | Text | Tool | Result | | ---- | ------------------------------------ | -------------------------------------------- | --------------------------------------------- | | 1 | [User]: | | | | | Fix the bug: kwargs not passed... | | | | 2 | I'll help you fix that bug. | **list_directory**(path="fastmcp") | `fastmcp/src [...]` | | | | | | | 3 | Let's examine the code. | **read_file**(path="fastmcp/main.py", [...]) | `def run_application(app, \*\*kwargs): [...]` | | 4 | I found the issue. | **edit_file**(path="fastmcp/core.py", [...]) | `Made edit to fastmcp/core.py` | | 5 | Let's check if there are any errors. | **diagnostics**() | `No errors found` | ### Implementation details `src/explorer.html` contains the template. You can open this template in a browser as is, and it will show some dummy values. But the main use is to set the `threadsData` variable with real data, which then will be used instead of the dummy values. `src/explorer.rs` takes one or more JSON files as generated by `cargo run -p eval`, and outputs an HTML file for rendering these threads. Refer dummy data in `explorer.html` for a sample format.
