SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Identify gaps in test coverage and propose minimal high-value tests to close them.

Core Features & Use Cases

Gap analysis: scans the codebase to identify missing tests for changed files, untested error paths, and untested branches
Regression tracking: references prior failures from .codebase/FAILURES.json to highlight where regression tests are missing
Prioritized workload: outputs a ranked list of high-value tests to add, with a minimal viable test set

Quick Start

Run the skill on a proposed feature change to obtain a ranked list of test gaps and the minimum viable tests to close them.

FAQPage Schema

How do I identify gaps in test coverage for changed files?▼

Identify test coverage gaps by scanning codebases to find missing tests for changed files, untested error paths, and untested branches. This highlights where testing effort is needed most across your project.

How do I prioritize regression tests after a bug fix?▼

Prioritize regression tests by referencing prior failures from .codebase/FAILURES.json. This highlights exactly where regression tests are missing and ranks them to focus your testing workload after bug fixes.

What is the best way to propose minimal high-value tests during feature development?▼

The best way to propose minimal high-value tests is to analyze files, tests, and failure history together. This produces a ranked gap report and a suggested set of three to five tests to close coverage gaps.

Can I get a ranked list of missing tests for codebase maintenance?▼

Yes, you can get a ranked list of missing tests for codebase maintenance. The analysis leverages existing test discovery patterns and failure logs to output a prioritized list of high-value tests to add.

Do I need a specific failure log format to detect missing regression tests?▼

You need a .codebase/FAILURES.json file to detect missing regression tests. The skill references this specific failure history to highlight where regression tests are currently absent in your codebase.
