-## Files to read
+## Focus On
 
-- `tests/` — all existing test files for patterns and conventions
-- `tests/test_models.py` — DB model tests (follow this pattern for core/ tests)
-- `tests/test_api.py` — API endpoint tests (follow for web/api.py tests)
-- `tests/test_runner.py` — pipeline/agent runner tests
-- Source files changed in the previous step
+- Files to read: `tests/test_models.py`, `tests/test_api.py`, `tests/test_runner.py`, changed source files
+- Test isolation — use in-memory SQLite (`:memory:`), not `kin.db`
+- Mocking subprocess — mock `subprocess.run` when testing agent runner; never call actual Claude CLI
+- One test per behavior — don't combine multiple assertions without clear reason
+- Test names: describe the scenario (`test_update_task_sets_updated_at`, not `test_task`)
+- Acceptance criteria coverage — if provided, every criterion must have a corresponding test
+- Observable behavior only — test return values and side effects, not implementation internals
 
-## Running tests
+## Quality Checks
 
-Execute: `python -m pytest tests/ -v` from the project root.
-For a specific test file: `python -m pytest tests/test_models.py -v`
+- All new tests use in-memory SQLite — never the real `kin.db`
+- Subprocess is mocked when testing agent runner
+- Test names are descriptive and follow project conventions
+- Every acceptance criterion has a corresponding test (when criteria are provided)
+- All existing tests still pass — no regressions introduced
+- Human-readable Verdict is in plain Russian, 2-3 sentences, no code snippets
 
-## Rules
-
-- Use `pytest`. No unittest, no custom test runners.
-- Tests must be isolated — use in-memory SQLite (`":memory:"`), not the real `kin.db`.
-- Mock `subprocess.run` when testing agent runner (never call actual Claude CLI in tests).
-- One test per behavior — don't combine multiple assertions in one test without clear reason.
-- Test names must describe the scenario: `test_update_task_sets_updated_at`, not `test_task`.
-- Do NOT test implementation internals — test observable behavior and return values.
-- If `acceptance_criteria` is provided in the task, ensure your tests explicitly verify each criterion.
