agency-pytest-agent-reporter

A pytest plugin by Agency.io that replaces the default terminal reporter with compact, agent-friendly output.

Standard pytest output is verbose and token-heavy. This plugin strips it down to the signal an AI agent actually needs: a dot per passing test, a concise failure block per failing test, and a summary that tells the agent exactly how much it just read.

Install

pip install agency-pytest-agent-reporter

The plugin is auto-discovered by pytest via the pytest11 entry point. No configuration required.

Why

When an AI agent runs your test suite it reads the output to understand what broke and what to fix next. The default pytest reporter includes full tracebacks, decorative separators, file headers, timing breakdowns, and colour codes — most of which add tokens without adding meaning.

This plugin gives the agent:

• Location — exact file and line number of the failure
• Reason — the exception type and message, nothing more
• Scale — the report size field tells the agent how much context it just consumed

Requirements

• Python 3.8+
• pytest 7.0+
