## What it is
A Python library that reformats exception tracebacks into readable, colorized output. It can be installed globally via the Python startup procedure or imported per-project, with configurable display options.

## Use cases
- make python tracebacks easier to read
- colorize python exception output in the terminal
- show local variables in stack traces
- filter stack trace frames by path whitelist or blacklist
- prettify errors when a framework overrides stderr

## When to choose
- you want clearer, colorized tracebacks for CLI scripts or development
- you want a one-line global setup via python startup
- you need configurable traceback display like line numbers and local variables

## When to avoid
- you need structured machine-readable error logs for production monitoring
- your environment has no color terminal support and you dislike monochrome output
- you rely on frameworks that fully control exception handling and cannot use excepthook

## Facets
- artifact type: library
- maturity: stable
- function: developer-tools, error-handling, logging
- domain: developer-tools
- platform: python, cli, cross-platform
- tags: traceback-formatting, exception-output, terminal-colors, excepthook, command-line
