Overview

This skill is for analyzing a code change and adding appropriate test coverage. It covers both unit tests and randomized/fuzz tests, ensuring that new functionality is tested and bug fixes include regression tests.

This skill involves a fair amount of work. Consider splitting it into pieces and running each piece as a subagent (e.g., one for analyzing test needs, one for writing unit tests, one for randomized tests). Keep each subagent focused on a moderate amount of work so it doesn't get lost or wander off track.

The output is either confirmation that tests were added (with details), or confirmation that no additional tests are needed.

Inputs

Before starting the analysis, gather the following information (if running as a subagent, the invoking agent should provide these; otherwise, determine them yourself or ask the user):
