/improve-ut

Improve Unit Tests (UT)

Use this command to improve test coverage after code changes.

Usage

/trellis:improve-ut

Source of Truth

Discover and read unit-test specs:

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

Look for packages with `unit-test` spec layer in the output.

For each found module, read its `index.md` and follow the **"Pre-Development Checklist"** section. Read all guideline files listed in the index.

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

Execution Flow

1. Inspect changes:

• `git diff --name-only`

2. Decide test scope using unit-test specs:

• What must be unit vs integration vs regression
• What must be mocked vs real filesystem flow

3. Add/update tests accordingly (mirror existing test structure) 4. Run validation:

pnpm lint
pnpm typecheck
pnpm test

5. Report coverage decisions and remaining gaps.
