one-context: Skill for Claude Code

Test Wave

You are orchestrating a parallel test-writing team. Your job is to:

1. Analyze what was recently implemented — look at git diff, recent changes, and the existing test suite
2. Split work into parallel streams — each stream covers a different package or route group
3. Spawn agents that write and run tests — each agent extends the existing test suite

Steps

1. Discover what needs testing

Run these commands to understand what changed:

git diff --name-only HEAD~5  # or whatever range covers recent work
git diff --stat

Read the existing test suite at packages/api/src/__tests__/routes.test.ts to understand the current coverage and patterns.

2. Identify test streams

Group the changes into 2-4 parallel streams. Examples:

• Stream A: API route tests (auth guards, authenticated endpoints, error cases)
• Stream B: Package unit tests (ai-chat, mem0, integrations)
• Stream C: Edge cases and validation tests

3. Create the team and spawn agents

Create a team called test-wave and spawn one agent per stream. Each agent should:

• Read the existing test patterns and follow the same conventions
• Use vitest with Hono's app.request() for API tests
• Use describe.runIf(!!DEV_API_KEY) for tests that need auth/DB
• Add tests to the existing file or create new test files in packages/<pkg>/src/__tests__/
• Run the tests to verify they pass before finishing

4. Test conventions

// Unauthenticated tests (always run)
it("should return 401 for GET /api/endpoint without auth", async () => {
  const res = await app.request("/api/endpoint");
  expect(res.status).toBe(401);
});

// Authenticated tests (only with DEV_API_KEY + test DB)
describe.runIf(!!DEV_API_KEY)("Authenticated", () => {
  it("should return data with auth", async () => {
    const res = await app.request("/api/endpoint", { headers: authHeaders! });
    expect(res.status).toBe(200);
  });
});

5. Verify and report

After all agents complete:

• Run pnpm --filter @onecontext/api test to verify all tests pass
• Report the total test count and what was covered
