autonomous-ai-agency: Skill for Claude Code

Skill: test-first-executor

When to Use

Use this skill whenever:

• Adding a new function, class, or FastAPI endpoint
• Fixing a bug (regression test required)
• Adding a new agent tool or router capability
• A reviewer asks "where are the tests?"

Instructions

Step 1 — Identify what needs testing

• What is the expected input/output?
• What are the failure modes?
• Is there a risky edge case (empty input, auth bypass, model unavailability)?

Step 2 — Write the test first

For this repo, tests live in tests/. Match the pattern:

tests/test_<module>.py     # mirrors src module name

Test structure template:

"""Tests for <module>.<Class>."""
from __future__ import annotations

import pytest
# imports

# ── Fixtures ──────────────────────────────────────────────────────────────────

@pytest.fixture
def some_fixture():
    ...

# ── Happy path ────────────────────────────────────────────────────────────────

def test_<function>_<expected_outcome>():
    ...

# ── Edge cases ────────────────────────────────────────────────────────────────

def test_<function>_raises_on_<bad_input>():
    with pytest.raises(SomeError):
        ...

# ── Regression ────────────────────────────────────────────────────────────────

def test_regression_<issue_description>():
    # Previously this caused <symptom>. Fixed in <commit/version>.
    ...

Step 3 — Confirm the test FAILS before implementation

Run pytest -x tests/test_<module>.py::test_<name>. A test that passes immediately (before implementation) is not testing the right thing.

Step 4 — Implement until the test passes

Step 5 — Run the full suite

pytest -x

All pre-existing tests must still pass.

Step 6 — Check coverage of risky paths

For any change to admin_auth.py, key_store.py, agent/tools.py:

• Write a test that specifically exercises the security boundary.
• Confirm the test would catch a regression if the boundary were removed.
