Agent responses (test execution) + +Async allows running many operations concurrently: + +```python +# Without async: 100 tests × 500ms = 50 seconds +# With async (10 concurrent): 100 tests / 10 × 500ms = 5 seconds +``` + +The semaphore in `orchestrator.py` controls concurrency: + +```python +semaphore = asyncio.Semaphore(self.config.advanced.concurrency) + +async def _run_single_mutation(self, mutation): + async with semaphore: # Limits concurrent executions + return await self.agent.invoke(mutation.mutated) +``` + +--- + +### Q: Why is there both an `orchestrator.py` and a `runner.py`? + +**A:** They serve different purposes: + +- **`runner.py`**: High-level API for users - simple `EntropixRunner.run()` interface +- **`orchestrator.py`**: Internal coordination logic - handles the complex flow + +This separation allows: +- `runner.py` to provide a clean facade +- `orchestrator.py` to be refactored without breaking the public API +- Different entry points (CLI, programmatic) to use the same core logic + +--- + +## Configuration System + +### Q: Why Pydantic instead of dataclasses or attrs? + +**A:** Pydantic was chosen for several reasons: + +1. **Automatic Validation**: Built-in validators with clear error messages + ```python + class MutationConfig(BaseModel): + count: int = Field(ge=1, le=100) # Validates range automatically + ``` + +2. **Environment Variable Support**: Native expansion + ```python + endpoint: str = Field(default="${AGENT_URL}") + ``` + +3. **YAML/JSON Serialization**: Works out of the box +4. **IDE Support**: Type hints provide autocomplete + +--- + +### Q: Why use environment variable expansion in config? + +**A:** Security best practice - secrets should never be in config files: + +```yaml +# BAD: Secret in file (gets committed to git) +headers: + Authorization: "Bearer sk-1234567890" + +# GOOD: Reference environment variable +headers: + Authorization: "Bearer ${API_KEY}" +``` + +Implementation in `config.py`: + +```python +def expand_env_vars(value: str) -> str: + """Replace ${VAR} with environment variable value.""" + pattern = r'\$\{([^}]+)\}' + def replacer(match): + var_name = match.group(1) + return os.environ.get(var_name, match.group(0)) + return re.sub(pattern, replacer, value) +``` + +--- + +### Q: Why is MutationType defined as `str, Enum`? + +**A:** String enums serialize directly to YAML/JSON: + +```python +class MutationType(str, Enum): + PARAPHRASE = "paraphrase" +``` + +This allows: +```yaml +# In config file - uses string value directly +mutations: + types: + - paraphrase # Works! + - noise +``` + +If we used a regular Enum, we'd need custom serialization logic. + +--- + +## Mutation Engine + +### Q: Why use a local LLM (Ollama) instead of cloud APIs? + +**A:** Several important reasons: + +| Factor | Local LLM | Cloud API | +|--------|-----------|-----------| +| **Cost** | Free | $0.01-0.10 per mutation | +| **Privacy** | Data stays local | Prompts sent to third party | +| **Rate Limits** | None | Often restrictive | +| **Latency** | Low | Network dependent | +| **Offline** | Works | Requires internet | + +For a test run with 100 prompts × 20 mutations = 2000 API calls, cloud costs would add up quickly. + +--- + +### Q: Why Qwen Coder 3 8B as the default model? + +**A:** We evaluated several models: + +| Model | Mutation Quality | Speed | Memory | +|-------|-----------------|-------|--------| +| Qwen Coder 3 8B | ⭐⭐⭐⭐ | ⭐⭐⭐ | 8GB | +| Llama 3 8B | ⭐⭐⭐ | ⭐⭐⭐ | 8GB | +| Mistral 7B | ⭐⭐⭐ | ⭐⭐⭐⭐ | 6GB | +| Phi-3 Mini | ⭐⭐ | ⭐⭐⭐⭐⭐ | 4GB | + +Qwen Coder 3 was chosen because: +1. Excellent at understanding and modifying prompts +2. Good balance of quality vs. speed +3. Runs on consumer hardware (8GB VRAM) + +--- + +### Q: How does the mutation template system work? + +**A:** Templates are stored in `templates.py` and formatted with the original prompt: + +```python +TEMPLATES = { + MutationType.PARAPHRASE: """ + Rewrite this prompt with different words but same meaning. + + Original: {prompt} + + Rewritten: + """, + MutationType.NOISE: """ + Add 2-3 realistic typos to this prompt: + + Original: {prompt} + + With typos: + """ +} +``` + +The engine fills in `{prompt}` and sends to the LLM: + +```python +template = TEMPLATES[mutation_type] +filled = template.format(prompt=original_prompt) +response = await self.client.generate(model=self.model, prompt=filled) +``` + +--- + +### Q: What if the LLM returns malformed mutations? + +**A:** We have several safeguards: + +1. **Parsing Logic**: Extracts text between known markers +2. **Validation**: Checks mutation isn't identical to original +3. **Retry Logic**: Regenerates if parsing fails +4. **Fallback**: Uses simple string manipulation if LLM fails + +```python +def _parse_mutation(self, response: str) -> str: + # Try to extract the mutated text + lines = response.strip().split('\n') + for line in lines: + if line and not line.startswith('#'): + return line.strip() + raise MutationParseError("Could not extract mutation") +``` + +--- + +## Assertion System + +### Q: Why separate deterministic and semantic assertions? + +**A:** They have fundamentally different characteristics: + +| Aspect | Deterministic | Semantic | +|--------|---------------|----------| +| **Speed** | Nanoseconds | Milliseconds | +| **Dependencies** | None | sentence-transformers | +| **Reproducibility** | 100% | May vary slightly | +| **Use Case** | Exact matching | Meaning matching | + +Separating them allows: +- Running deterministic checks first (fast-fail) +- Making semantic checks optional (lighter installation) + +--- + +### Q: How does the SimilarityChecker work internally? + +**A:** It uses sentence embeddings and cosine similarity: + +```python +class SimilarityChecker: + def check(self, response: str, latency_ms: float) -> CheckResult: + # 1. Embed both texts to vectors + response_vec = self.embedder.embed(response) # [0.1, 0.2, ...] + expected_vec = self.embedder.embed(self.expected) # [0.15, 0.18, ...] + + # 2. Calculate cosine similarity + similarity = cosine_similarity(response_vec, expected_vec) + # Returns value between -1 and 1 (typically 0-1 for text) + + # 3. Compare to threshold + return CheckResult(passed=similarity >= self.threshold) +``` + +The embedding model (`all-MiniLM-L6-v2`) converts text to 384-dimensional vectors that capture semantic meaning. + +--- + +### Q: Why is the embedder a class variable with lazy loading? + +**A:** The embedding model is large (23MB) and takes 1-2 seconds to load: + +```python +class SimilarityChecker: + _embedder: LocalEmbedder | None = None # Class variable, shared + + @property + def embedder(self) -> LocalEmbedder: + if SimilarityChecker._embedder is None: + SimilarityChecker._embedder = LocalEmbedder() # Load once + return SimilarityChecker._embedder +``` + +Benefits: +1. **Lazy Loading**: Only loads if semantic checks are used +2. **Shared Instance**: All SimilarityCheckers share one model +3. **Memory Efficient**: One copy in memory, not one per checker + +--- + +### Q: How does PII detection work? + +**A:** Uses regex patterns for common PII formats: + +```python +PII_PATTERNS = [ + (r'\b\d{3}-\d{2}-\d{4}\b', 'SSN'), # 123-45-6789 + (r'\b\d{16}\b', 'Credit Card'), # 1234567890123456 + (r'\b[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,}\b', 'Email'), + (r'\b\d{3}[-.]?\d{3}[-.]?\d{4}\b', 'Phone'), # 123-456-7890 +] + +def check(self, response: str, latency_ms: float) -> CheckResult: + for pattern, pii_type in self.PII_PATTERNS: + if re.search(pattern, response, re.IGNORECASE): + return CheckResult( + passed=False, + details=f"Found potential {pii_type}" + ) + return CheckResult(passed=True) +``` + +--- + +## Performance & Rust + +### Q: Why Rust for performance-critical code? + +**A:** Python is slow for CPU-bound operations. Benchmarks show: + +``` +Levenshtein Distance (5000 iterations): + Python: 5864ms + Rust: 67ms + Speedup: 88x +``` + +Rust was chosen over alternatives because: +- **vs C/C++**: Memory safety, easier to write correct code +- **vs Cython**: Better tooling (cargo), cleaner code +- **vs NumPy**: Works on strings, not just numbers + +--- + +### Q: How does the Rust/Python bridge work? + +**A:** Uses PyO3 for bindings: + +```rust +// Rust side (lib.rs) +#[pyfunction] +fn levenshtein_distance(s1: &str, s2: &str) -> usize { + // Rust implementation +} + +#[pymodule] +fn entropix_rust(m: &PyModule) -> PyResult<()> { + m.add_function(wrap_pyfunction!(levenshtein_distance, m)?)?; + Ok(()) +} +``` + +```python +# Python side (performance.py) +try: + import flakestorm_rust + _RUST_AVAILABLE = True +except ImportError: + _RUST_AVAILABLE = False + +def levenshtein_distance(s1: str, s2: str) -> int: + if _RUST_AVAILABLE: + return entropix_rust.levenshtein_distance(s1, s2) + # Pure Python fallback + ... +``` + +--- + +### Q: Why provide pure Python fallbacks? + +**A:** Accessibility and reliability: + +1. **Easy Installation**: `pip install flakestorm` works without Rust toolchain +2. **Platform Support**: Works on any Python platform +3. **Development**: Faster iteration without recompiling Rust +4. **Testing**: Can test both implementations for parity + +The tradeoff is speed, but most time is spent waiting for LLM/agent responses anyway. + +--- + +## Agent Adapters + +### Q: Why use the Protocol pattern for agents? + +**A:** Enables type-safe duck typing: + +```python +class AgentProtocol(Protocol): + async def invoke(self, prompt: str) -> AgentResponse: ... +``` + +Any class with a matching `invoke` method works, even if it doesn't inherit from a base class. This is more Pythonic than Java-style interfaces. + +--- + +### Q: How does the HTTP adapter handle different API formats? + +**A:** Through configurable templates: + +```yaml +agent: + endpoint: "https://api.example.com/v1/chat" + request_template: | + {"messages": [{"role": "user", "content": "{prompt}"}]} + response_path: "$.choices[0].message.content" +``` + +The adapter: +1. Replaces `{prompt}` in the template +2. Sends the formatted JSON +3. Uses JSONPath to extract the response + +This supports OpenAI, Anthropic, custom APIs, etc. + +--- + +### Q: Why is there a Python adapter? + +**A:** Bypasses HTTP overhead for local testing: + +```python +# Instead of: HTTP request → your server → your code → HTTP response +# Just: your_function(prompt) → response + +class PythonAgentAdapter: + async def invoke(self, prompt: str) -> AgentResponse: + # Import the module dynamically + module_path, func_name = self.endpoint.rsplit(":", 1) + module = importlib.import_module(module_path) + func = getattr(module, func_name) + + # Call directly + start = time.perf_counter() + response = await func(prompt) if asyncio.iscoroutinefunction(func) else func(prompt) + latency = (time.perf_counter() - start) * 1000 + + return AgentResponse(text=response, latency_ms=latency) +``` + +--- + +## Testing & Quality + +### Q: Why are tests split by module? + +**A:** Mirrors the source structure for maintainability: + +``` +tests/ +├── test_config.py # Tests for core/config.py +├── test_mutations.py # Tests for mutations/ +├── test_assertions.py # Tests for assertions/ +├── test_performance.py # Tests for performance module +``` + +When fixing a bug in `config.py`, you immediately know to check `test_config.py`. + +--- + +### Q: Why use pytest over unittest? + +**A:** Pytest is more Pythonic and powerful: + +```python +# unittest style (verbose) +class TestConfig(unittest.TestCase): + def test_load_config(self): + self.assertEqual(config.agent.type, AgentType.HTTP) + +# pytest style (concise) +def test_load_config(): + assert config.agent.type == AgentType.HTTP +``` + +Pytest also offers: +- Fixtures for setup/teardown +- Parametrized tests +- Better assertion introspection + +--- + +### Q: How should I add tests for a new feature? + +**A:** Follow this pattern: + +1. **Create test file** if needed: `tests/test_.py` +2. **Write failing test first** (TDD) +3. **Group related tests** in a class +4. **Use fixtures** for common setup + +```python +# tests/test_new_feature.py +import pytest +from flakestorm.new_module import NewFeature + +class TestNewFeature: + @pytest.fixture + def feature(self): + return NewFeature(config={...}) + + def test_basic_functionality(self, feature): + result = feature.do_something() + assert result == expected + + def test_edge_case(self, feature): + with pytest.raises(ValueError): + feature.do_something(invalid_input) +``` + +--- + +## Extending flakestorm + +### Q: How do I add a new mutation type? + +**A:** Three steps: + +1. **Add to enum** (`mutations/types.py`): + ```python + class MutationType(str, Enum): + # ... existing types + MY_NEW_TYPE = "my_new_type" + ``` + +2. **Add template** (`mutations/templates.py`): + ```python + TEMPLATES[MutationType.MY_NEW_TYPE] = """ + Your prompt template here. + + Original: {prompt} + + Modified: + """ + ``` + +3. **Add default weight** (`core/config.py`): + ```python + class MutationConfig(BaseModel): + weights: dict = { + # ... existing weights + MutationType.MY_NEW_TYPE: 1.0, + } + ``` + +--- + +### Q: How do I add a new assertion type? + +**A:** Four steps: + +1. **Create checker class** (`assertions/deterministic.py` or `semantic.py`): + ```python + class MyNewChecker(BaseChecker): + def check(self, response: str, latency_ms: float) -> CheckResult: + # Your logic here + passed = some_condition(response) + return CheckResult( + passed=passed, + check_type=InvariantType.MY_NEW_TYPE, + details="Explanation" + ) + ``` + +2. **Add to enum** (`core/config.py`): + ```python + class InvariantType(str, Enum): + # ... existing types + MY_NEW_TYPE = "my_new_type" + ``` + +3. **Register in verifier** (`assertions/verifier.py`): + ```python + CHECKER_REGISTRY = { + # ... existing checkers + InvariantType.MY_NEW_TYPE: MyNewChecker, + } + ``` + +4. **Add tests** (`tests/test_assertions.py`) + +--- + +### Q: How do I add a new report format? + +**A:** Create a new generator: + +```python +# reports/markdown.py +class MarkdownReportGenerator: + def __init__(self, results: TestResults): + self.results = results + + def generate(self) -> str: + """Generate markdown content.""" + md = f"# flakestorm Report\n\n" + md += f"**Score:** {self.results.statistics.robustness_score:.2f}\n" + # ... more content + return md + + def save(self, path: Path = None) -> Path: + path = path or Path(f"reports/report_{timestamp}.md") + path.write_text(self.generate()) + return path +``` + +Then add CLI option in `cli/main.py`. + +--- + +## Common Issues + +### Q: Why am I getting "Cannot connect to Ollama"? + +**A:** Ollama service isn't running. Fix: + +```bash +# Start Ollama +ollama serve + +# Verify it's running +curl http://localhost:11434/api/version +``` + +--- + +### Q: Why is mutation generation slow? + +**A:** LLM inference is inherently slow.
