Improve Unit Tests (UT)

Use this skill to improve test coverage after code changes.

Usage

$improve-ut

Source of Truth

Discover and read unit-test specs dynamically:

Discover available packages and their spec layers

python3 ./.trellis/scripts/get_context.py --mode packages

Look for packages with unit-test spec layer in the output. For each discovered unit-test/ directory, read all spec files inside it (e.g., index.md , conventions.md , integration-patterns.md , mock-strategies.md ).

If this skill conflicts with the unit-test specs, the specs win.

Execution Flow

• Inspect changed files:

• git diff --name-only

• Decide test scope using unit-test specs:

• unit vs integration vs regression

• mock vs real filesystem flow

• Add/update tests using existing project test patterns

• Run validation:

pnpm lint pnpm typecheck pnpm test

• Summarize decisions, updates, and remaining test gaps.
