grill-with-docs, improve-codebase-architecture, tdd, and triage kept non-spec markdown files at their skill root, in violation of skill-audit's file-structure.md rule (only SKILL.md/README.md belong at the root; everything else lives in scripts/, references/, assets/ or tests/). A root-level file is invisible to the ADR-0020 dangling-reference gate, which only resolves unqualified `references/...` pointers. - Moved and renamed to lowercase-kebab-case under references/: grill-with-docs (ADR-FORMAT.md, CONTEXT-FORMAT.md), improve-codebase-architecture (DEEPENING.md, INTERFACE-DESIGN.md, LANGUAGE.md), tdd (five files, casing was already fine), triage (AGENT-BRIEF.md, OUT-OF-SCOPE.md). - Updated every in-skill link to the new references/ paths, including link text that still showed the old uppercase filenames. - Fixed improve-codebase-architecture/SKILL.md's cross-skill citation of grill-with-docs's two files to the sanctioned possessive form with the references/ segment included. - Updated all four skills' README.md file tables to match. - Regenerated the flat content mirror via scripts/sync-plugin-content.sh --all.

Good and Bad Tests
Good Tests
Integration-style: Test through real interfaces, not mocks of internal parts.
// GOOD: Tests observable behavior
test("user can checkout with valid cart", async () => {
const cart = createCart();
cart.add(product);
const result = await checkout(cart, paymentMethod);
expect(result.status).toBe("confirmed");
});
Characteristics:
- Tests behavior users/callers care about
- Uses public API only
- Survives internal refactors
- Describes WHAT, not HOW
- One logical assertion per test
Bad Tests
Implementation-detail tests: Coupled to internal structure.
// BAD: Tests implementation details
test("checkout calls paymentService.process", async () => {
const mockPayment = jest.mock(paymentService);
await checkout(cart, payment);
expect(mockPayment.process).toHaveBeenCalledWith(cart.total);
});
Red flags:
- Mocking internal collaborators
- Testing private methods
- Asserting on call counts/order
- Test breaks when refactoring without behavior change
- Test name describes HOW not WHAT
- Verifying through external means instead of interface
// BAD: Bypasses interface to verify
test("createUser saves to database", async () => {
await createUser({ name: "Alice" });
const row = await db.query("SELECT * FROM users WHERE name = ?", ["Alice"]);
expect(row).toBeDefined();
});
// GOOD: Verifies through interface
test("createUser makes user retrievable", async () => {
const user = await createUser({ name: "Alice" });
const retrieved = await getUser(user.id);
expect(retrieved.name).toBe("Alice");
});
