Implement a simple workflow that mimics a typical SDLC workflow for breaking down problems, and iteratively improving the units of work.

Workflow

Phase 1: Codebase Context

  • Retrieves repository file structure
  • Generates questions about the codebase based on PRD, tech spec, and repo
    structure
  • Queries the repository to answer those questions
  • Stores the context for later use

Phase 2: Story Generation (Iterative)

  • Generates initial list of user story titles based on PRD, tech spec, and
    codebase context
  • Shows story titles to user for approval
  • If rejected: takes user comments and regenerates stories (loops until approved)
  • If approved: moves to next phase

Phase 3: Story Detailing (Per Story, Iterative)

  • For each story in the approved list:
    • Step 3a: Defines acceptance criteria for the story
    • Step 3b: Enriches the story with additional context from PRD, tech spec, and
      repo context
    • Shows the detailed story (title + ACs + context) to user
    • If rejected: takes comments and revises both ACs and context (loops until
      approved)
    • If approved: saves the detailed story and moves to next one

Phase 4: Final Output

  • Prints complete list of all stories with their acceptance criteria and enriched
    context
  • Returns the final story list

Key Characteristics:

  • Two-level iteration: story list approval, then individual story detailing
  • Combines PRD, tech spec, and live codebase context throughout
  • User has veto power at both the story list level and individual story level

TODOs

  • Find a better hook for ruff check fix (perhaps pre-push / pre-commit)
  • Clean up duplicated request creation in follow up calls
  • Figure out confusion when there's mixed feedback for ACs and enriched context
  • Refactor logging to use module name instead of manual function/file context

Notes

  • Moving models to separate file so they can be used in any higher level code
  • Separate calling AI from domain logic
  • Extract tool call ritual - making another request with function call and response makes the response complete and allows continuation
  • Using OpenAI's conversations API to manage state with global state assumption (only 1 ongoing conversation per CLI run)
  • Structured logging pollutes code a bit right now, will tweak as needed with progress
  • story_machine.py has been superseded by current implementation
  • New implementations don't have tests yet
  • Currently using Claude Code SDK for repo questions, but can switch to something else in the future (preferably something that doesn't need local codebase)
  • Claude Code SDK is isolated in ai.py for easy implementation swap
  • CC CLI needs to be installed on user machine for this to work

- Moving them to another file so it can be used in any higher level code
- Separate calling ai from domain logic
- Simplify parsing response using list comprehension
- Extract tool call, might reuse it for other calls
- CLI calls into workflow
- Removing the older flow temporarily, not generating files, no target dir
- Extracting reasoning effort into env, and refactoring settings to
  have the file name specified inside config.py itself
- Extract spinner as an activity so it can be used only around parts
of workflow
- Rename FeedbackResponse and status appropriately
- Make another request to responses with the function call and
response both.
- Not doing this makes the response incomplete, and we can't continue it.
- Note that the actual tool call implementation is just an empty
string, because there is no tool, just that the tool call args are in json.
- This was removing imports
- Need to find a better hook for this, perhaps pre-push / pre-commit
- Use OpenAI's conversations API to manage state
- Use global state with the assumption that there will only ever be 1
  ongoing conversation per CLI run
- Only prompt to use the tool, nothing else.
- Don't enforce the story structure too much, be a bit flexible
- Add basic t-shirt size estimates
- Add a note about ordering stories
- Add a note about cutting pieces for CRUD tasks
- Add prompt, activity and extension to workflow
- Aware that this pollutes the code a bit right now
- Adding function and file context for debuggability, should ideally
  just use module name. Will refactor this later.
- This is an init commit, will tweak logging as needed with progress
- Refactor ai.py to output reasoning, and then send it back
- Refactor it to use types defined in the python library
- And extract the response parsing into a function
- Some of the request creation is duplicated in the follow up. want to
  clean that up sometime.
- Remove story_machine.py. It has been superseeded by current
  implementation.
- CLI.py only has the basic cli setup. Workflow is extracted to its
  own.
- New implementations don't have tests yet.
- Add these details along with ACs, and then ask the user for
  feedback.
- Use the same prompt when iterating too. This makes it confusing when
  there's mixed feedback for ACs and enriched context. Need to figure
  this out.
- Given PRD and tech spec, get a list of relevant questions to ask
  about the codebase
- Reuse the existing call_openai function, just without tool calls
- Temporarily breaking the workflow until the next step of getting the
  codebase context is implemented
- Given repo and questions, get answers. Currently using claude code
sdk. But, can switch to something else in the future. Preferably
something that doesn't need a local codebase. Note that the SDK is
wrapper over the CC CLI. CC CLI needs to be installed on user machine
for this to work.

- Isolate claude code sdk integration into ai.py. We should be able to
swap out implementation easily enough.

- Setup config and environment for claude code sdk.

- Add CLI input for repo path, add to workflow input
- Continue the workflow with the added context of what's in the repo

Pull Request Review: Workflows

Overview

This PR implements a workflow system for breaking down problems into user stories with an iterative improvement process. The implementation is substantial (1179 additions, 752 deletions) and introduces several new architectural patterns.

🎯 Code Quality & Best Practices

✅ Strengths

  1. Good separation of concerns: activities.py, ai.py, types.py, and workflow.py provide clear module boundaries
  2. Type hints present: Functions have type annotations as per CLAUDE.md requirements
  3. Structured logging: Using structlog for better observability
  4. Configuration management: Proper use of Pydantic settings

⚠️ Issues Found

Critical Issues

  1. Missing Type Hints in Several Functions

    • ai.py:102: getattr calls without proper type narrowing
    • activities.py:109: Missing return type annotation for parse_text_from_response
  2. Inconsistent Error Handling

    • ai.py:267: Raises generic ValueError instead of specific exception
    • Missing try-except blocks around file I/O operations in cli.py:33-35
    • No error handling for OpenAI API failures in call_openai_api function
  3. Line Length Violations

    • activities.py:177: Line exceeds 120 chars (per CLAUDE.md)
    • Multiple lines in ai.py exceed the limit

Code Quality Issues

  1. Global State Management (ai.py:20)

    conversation_id: Optional[str] = None

    Global mutable state is problematic for testing and concurrent usage. Consider using a context manager or dependency injection pattern.

  2. Exception Handling (ai.py:267)

    raise ValueError("ANTHROPIC_API_KEY not found in .env file")

    Per CLAUDE.md guidelines, should catch specific exceptions. Consider creating custom exception types:

    class ConfigurationError(Exception):
        pass
    
    if not settings.anthropic_api_key:
        raise ConfigurationError("ANTHROPIC_API_KEY not found")
  3. Dynamic Attribute Setting (ai.py:97-100)

    setattr(response, "_reasoning_items", reasoning_items)
    setattr(response, "_function_calls", function_calls)

    This bypasses type safety. Consider wrapping the Response object in a domain-specific class:

    @dataclass
    class ParsedResponse:
        response: Response
        reasoning_items: List[ResponseReasoningItem]
        function_calls: List[ResponseFunctionToolCall]
  4. Spinner Implementation (activities.py:23-48)

    • Uses daemon threads which can cause issues on shutdown
    • The spinner writes to stderr without checking if it's a TTY
    • Consider using a library like rich or checking sys.stderr.isatty()

🐛 Potential Bugs

  1. Race Condition in Spinner (activities.py:40-47)
    The stop.set() and t.join() sequence could have timing issues. The thread might not have finished writing when the cleanup starts.

  2. Unclosed Resources (ai.py:149)
    The OpenAI client is created but never explicitly closed. While Python's garbage collector will handle this, it's better practice to use context managers:

    with OpenAI(api_key=settings.openai_api_key) as client:
        # use client
  3. File Path Handling (workflow.py:33-35)

    prd_content = Path(prd_path).read_text()

    No validation that the file exists or is readable. Should handle FileNotFoundError, PermissionError, etc.

  4. Empty Response Handling (activities.py:200)

    return updated_stories[0] if updated_stories else story

    Silently returns the original story if API fails. Should log this case or raise an error.

🚀 Performance Considerations

  1. Synchronous API Calls in Loop (workflow.py:71-78)
    The workflow processes stories sequentially. Since you mentioned wanting parallelization in the TODO doc, consider using asyncio.gather() for concurrent story processing:

    enriched_stories = await asyncio.gather(
        *[enrich_story_async(story) for story in stories]
    )
  2. Repeated Settings Initialization
    Settings() is called in multiple functions. Consider injecting it once at the top level.

  3. Large Prompt Loading
    get_prompt() reads files synchronously every time. Consider caching prompt templates.

🔒 Security Concerns

  1. API Key Exposure

    • Keys are properly loaded from .env
    • Environment variable is set in ai.py:270 which persists for the process lifetime - consider more scoped approach
  2. Input Validation

    • No validation of user inputs in get_human_input()
    • File paths from CLI args aren't validated before use
    • Consider sanitizing repo paths before passing to Claude SDK
  3. Prompt Injection Risk
    User comments are directly interpolated into prompts without sanitization. While OpenAI has protections, consider adding input validation.

🧪 Test Coverage

Critical Gap

No tests for the new implementation (as noted in PR description). This is a significant concern given the complexity:

  • activities.py: 284 lines, 0 tests
  • ai.py: 304 lines, 0 tests
  • workflow.py: 100+ lines, 0 tests

Required Tests (per CLAUDE.md)

  1. Unit tests for each activity function
  2. Mock tests for OpenAI/Anthropic API calls
  3. Integration tests for the workflow
  4. Error case tests (API failures, invalid inputs, etc.)

Suggest using pytest with fixtures:

@pytest.fixture
def mock_openai_client(monkeypatch):
    # Mock OpenAI responses
    pass

@pytest.mark.anyio  # As per CLAUDE.md for async tests
async def test_get_codebase_context(mock_openai_client):
    # Test implementation
    pass

📝 Documentation Issues

  1. Missing Docstrings

    • workflow.py:18: w1() function lacks docstring
    • Several helper functions in activities.py need docs
  2. Incomplete Type Documentation

    • types.py: Enums and classes need docstrings explaining when to use each state
  3. README Update
    README was updated but doesn't explain the new workflow concept or show example usage

✨ Recommendations

High Priority

  1. Add comprehensive test suite - This should block merging
  2. Fix error handling - Add proper exception handling around all I/O and API calls
  3. Remove global state - Refactor conversation_id to use dependency injection
  4. Run formatters:
    uv run --frozen ruff format .
    uv run --frozen ruff check . --fix
    uv run --frozen pyright

Medium Priority

  1. Add input validation for file paths and user inputs
  2. Implement proper resource cleanup for API clients
  3. Add docstrings to all public functions
  4. Consider extracting the spinner to a separate utility module

Low Priority

  1. Refactor dynamic attributes to use proper domain classes
  2. Add prompt template caching for performance
  3. Consider using rich library for better CLI formatting

🎨 Style Notes

From CLAUDE.md:

  • ✅ Using uv correctly
  • ⚠️ Some lines exceed 120 chars
  • ⚠️ Need to run uv run --frozen ruff format .
  • ❌ Missing pytest configuration for anyio

📋 Before Merging Checklist

  • Add test suite with >80% coverage
  • Run and fix all formatting/linting issues
  • Add error handling for all I/O and API operations
  • Add docstrings to public APIs
  • Validate all file paths before use
  • Refactor global state
  • Update documentation with workflow examples
  • Address TODOs in PR description (especially the ruff check hook)

💭 Final Thoughts

This is a solid architectural foundation with good separation of concerns. The main concerns are:

  1. Lack of tests (blocking issue)
  2. Error handling gaps (important for production use)
  3. Global state management (affects testability)

The workflow concept is well-designed and the code is generally readable. With tests and improved error handling, this will be a strong addition to the codebase.

Great work on the structured approach! Looking forward to seeing the tests and fixes. 🚀

Code Review: Workflows PR

Overview

This PR introduces a significant refactor implementing a workflow-based approach. Changes: 1691 additions, 756 deletions.

Critical Issues

1. Global Mutable State - src/storymachine/ai.py:20

Global conversation_id breaks functional programming principles and causes issues with concurrent execution and testing.
Recommendation: Pass conversation_id as part of WorkflowInput or create a ConversationContext class.

2. Missing Test Coverage

Core workflow logic has zero test coverage, violating project guidelines.
Recommendation: Add unit and integration tests before merging.

3. Resource Leak - src/storymachine/logging.py:23

File handle never closed, causing descriptor leaks.
Recommendation: Use proper file rotation setup.

4. Unsafe Dynamic Attributes - src/storymachine/ai.py:100-103

Using setattr on OpenAI response objects violates immutability contract.
Recommendation: Create wrapper class instead.

Security Concerns

Environment Variable Mutation - src/storymachine/ai.py:276

Modifying os.environ at runtime can leak credentials and create race conditions.
Recommendation: Pass API keys directly to SDK.

API Key Validation Missing

No validation or redaction in logs.
Recommendation: Add field validators.

Other Issues

  • Missing error handling in answer_repo_questions
  • Broad exception handling instead of specific types
  • Type checking suppressions that could be fixed
  • Magic numbers should be in Settings
  • Sequential story processing could be parallelized
  • Prompt templates not cached

Must Fix Before Merge

  1. Add comprehensive test coverage
  2. Fix global conversation_id state
  3. Fix logging file handle leak
  4. Add error handling

Conclusion

Well-structured architecture but should NOT be merged without tests. Global state and resource leak also need fixing.

Estimated effort: Critical fixes 4-6h, test coverage 8-12h.

Happy to help implement fixes!

- nudging it to make parallel tool calls
- not read the full codebase

Code Review for PR #13: Workflows

This is a substantial refactoring that implements a workflow system for story generation. Overall, the architecture is clean with good separation of concerns.

Strengths

  1. Good separation of concerns between AI logic, workflow orchestration, and activities
  2. Proper use of type hints and Pydantic models
  3. Well-implemented structured logging with context
  4. Nice iterative workflow with human-in-the-loop validation

Critical Issues

1. Resource Leak in logging.py:23
The log file is opened but never closed. This will remain open for program lifetime.

2. Unsafe JSON Parsing in activities.py:96
No error handling for invalid JSON or missing keys. Will crash with unhandled exception. Should wrap in try/except per CLAUDE.md.

3. Global Mutable State in ai.py:20
Global conversation_id is problematic for testing, concurrent usage, and state management.

4. Missing Error Handling in activities.py:137-142
No exception handling for network errors, API failures, or invalid repo URLs. Per CLAUDE.md, should catch ConnectionError, TimeoutError.

5. Type Safety Issue in ai.py:69
Missing type hint for logger parameter.

Security Concerns

1. API Key Exposure in ai.py:276
Setting environment variables at runtime can expose secrets to child processes.

2. Logging Sensitive Data
Multiple locations log full API responses and prompts which may contain sensitive user data (ai.py:97, ai.py:303, activities.py:147).

3. Missing Input Validation
get_prompt doesn't validate kwargs which could allow template injection.

Performance Issues

1. Sequential Story Processing in workflow.py:64
Stories processed one-by-one. Could be parallelized using asyncio.gather for significant speedup.

2. Settings Recreated Every Call
Settings() instantiated repeatedly. Should be memoized per TODO in config.py:6.

Test Coverage Gap

Major Issue: No tests for new core modules:

  • activities.py (297 lines, 0 tests)
  • workflow.py (113 lines, 0 tests)
  • ai.py (304 lines, 0 tests)
  • types.py (47 lines, 0 tests)
  • logging.py (46 lines, 0 tests)

Per CLAUDE.md: "New features require tests". This is 807 lines of untested code.

Recommendations

High Priority:

  1. Add comprehensive tests for all new modules
  2. Fix resource leak in logging
  3. Add proper exception handling for JSON parsing and network calls
  4. Remove global mutable state
  5. Validate inputs to prevent crashes

Medium Priority:
6. Implement Settings memoization
7. Fix line length violations (120 char limit)
8. Add missing type hints
9. Parallelize story processing
10. Review and redact sensitive data in logs

Summary

Well-structured refactoring with good architecture, but has significant gaps in error handling, testing, and resource management. The lack of tests for 807 lines of new code is particularly concerning.

Recommendation: Request changes to address critical bugs and add test coverage before merging.

Code Review for PR #13: Workflows

Overview

This PR implements a significant refactoring that introduces a workflow-based architecture for breaking down PRDs and tech specs into user stories. The implementation is well-structured overall, but there are several areas that need attention before merging.


🔴 Critical Issues

1. Missing Tests for New Code

  • Issue: The PR introduces ~1700 lines of new code in activities.py, ai.py, workflow.py, types.py, and logging.py, but no corresponding unit tests
  • Files: src/storymachine/activities.py, src/storymachine/ai.py, src/storymachine/workflow.py, src/storymachine/logging.py
  • Impact: High - Zero test coverage for core workflow logic violates CLAUDE.md requirement: "New features require tests"
  • Recommendation:
    • Add tests for parse_stories_from_response() - line 89 in activities.py
    • Add tests for get_or_create_conversation() - line 48 in ai.py
    • Add tests for supports_reasoning_parameters() - line 23 in ai.py
    • Add tests for workflow state transitions in w1() - workflow.py:20
    • Add tests for error handling in get_codebase_context() - activities.py:114

2. Global Mutable State

  • Issue: Global conversation_id variable in ai.py:20 creates shared state that persists across workflow runs
  • File: src/storymachine/ai.py:20
  • Impact: High - Multiple CLI runs in the same process will share conversation state, breaking isolation
  • Code:
# Global conversation state
conversation_id: Optional[str] = None
  • Recommendation: Move conversation state to a class or pass it through function parameters. Consider using a context manager or dependency injection.

3. Broad Exception Handling Missing

  • Issue: Multiple async functions and API calls lack proper exception handling
  • Files:
    • activities.py:114 - get_codebase_context() has no try/except around ask-github call
    • ai.py:265 - answer_repo_questions() has no error handling for SDK failures
  • Impact: Medium-High - Per CLAUDE.md: "Catch specific exceptions where possible"
  • Recommendation: Add specific exception handling for network errors, API failures, and JSON parsing issues

🟡 Code Quality Issues

4. Inconsistent Type Annotations

  • Issue: Missing return type hint on _create_and_parse_response() parameter logger
  • File: src/storymachine/ai.py:68-70
  • Code:
def _create_and_parse_response(
    client: OpenAI, params: dict, logger, log_prefix: str  # logger has no type hint
) -> Response:
  • Impact: Medium - Violates CLAUDE.md requirement: "Type hints required for all code"
  • Recommendation: Add logger: structlog.BoundLogger type hint

5. Hardcoded Magic Values

  • Issue: Multiple hardcoded values that should be configurable
  • Files:
    • activities.py:141 - max_iterations=100 hardcoded
    • ai.py:22 - Model version strings hardcoded in set
  • Impact: Low-Medium - Reduces flexibility and makes testing harder
  • Recommendation: Move to config or constants

6. Line Length Violations

  • Issue: Several lines exceed 120 character limit per CLAUDE.md
  • Files:
    • activities.py:139 - 140+ characters
    • ai.py:228-235 - Complex dict comprehension exceeds limit
  • Recommendation: Run uv run --frozen ruff format . and uv run --frozen ruff check . --fix

7. Docstring Quality

  • Issue: Several public functions have minimal docstrings that don't describe parameters or return values
  • Examples:
    • get_codebase_context() - doesn't document the async nature or potential exceptions
    • problem_break_down() - doesn't explain the comments parameter behavior
  • Impact: Low-Medium - Violates CLAUDE.md: "Public APIs must have docstrings"
  • Recommendation: Add comprehensive docstrings with Args, Returns, and Raises sections

🟢 Performance Considerations

8. Sequential Story Processing

  • Issue: Stories are processed sequentially in workflow.py:64-108, but could be parallelized
  • File: src/storymachine/workflow.py:64-108
  • Impact: Low - Performance issue for PRDs with many stories
  • Recommendation: Consider using asyncio.gather() to process multiple stories in parallel, though this may conflict with the interactive approval workflow

9. File I/O on Every Log

  • Issue: logging.py:23 opens log file in append mode on every log entry
  • File: src/storymachine/logging.py:23
  • Code:
logger_factory=structlog.WriteLoggerFactory(file=log_file.open("a"))
  • Impact: Low - May cause file handle exhaustion with heavy logging
  • Recommendation: Consider using a context manager or buffered writer

🔒 Security Concerns

10. API Key Environment Variable Manipulation

  • Issue: ai.py:276 directly sets os.environ["ANTHROPIC_API_KEY"]
  • File: src/storymachine/ai.py:276
  • Impact: Medium - Modifying environment can affect other code and creates side effects
  • Code:
os.environ["ANTHROPIC_API_KEY"] = settings.anthropic_api_key
  • Recommendation: Check if Claude SDK supports passing API key as parameter instead of relying on environment variables

11. Potential Prompt Injection

  • Issue: User comments are directly interpolated into prompts without sanitization
  • Files:
    • activities.py:164 - comments parameter inserted directly into prompt
    • Various prompt files receive unsanitized user input
  • Impact: Low-Medium - Malicious comments could manipulate AI behavior
  • Recommendation: Add comment validation/sanitization or use structured prompt formats

📊 Test Coverage

12. No Tests for New Modules

  • Missing Test Files:
    • tests/test_activities.py - doesn't exist
    • tests/test_ai.py - doesn't exist
    • tests/test_workflow.py - doesn't exist
    • tests/test_logging.py - doesn't exist
    • tests/test_types.py - doesn't exist
  • Impact: Critical - Per CLAUDE.md: "New features require tests"
  • Recommendation: Achieve at least 70% coverage for new code before merging

✅ Positive Aspects

  1. Good Separation of Concerns: AI logic, activities, and workflow are well separated
  2. Structured Logging: Good use of structlog for observability
  3. Type Safety: Most code has proper type hints (besides noted issues)
  4. Clear Workflow Structure: The w1() workflow function is easy to follow
  5. User Experience: Spinner feedback and progressive disclosure are well implemented
  6. Documentation: CLAUDE.md guidelines are generally followed

📝 Recommendations Summary

Before Merging (Required):

  1. ✅ Add comprehensive unit tests for all new modules
  2. ✅ Fix global conversation_id state management
  3. ✅ Add exception handling for async API calls
  4. ✅ Fix type hint for logger parameter in ai.py:69
  5. ✅ Run formatters: uv run --frozen ruff format . && uv run --frozen ruff check . --fix

Nice to Have:

  1. Move hardcoded values to config
  2. Improve docstrings with Args/Returns/Raises
  3. Consider parallelizing story processing
  4. Remove os.environ mutation for API keys
  5. Add input sanitization for user comments

Test Execution

Before merging, ensure all tests pass:

PYTEST_DISABLE_PLUGIN_AUTOLOAD="" uv run --frozen pytest
uv run --frozen pyright
uv run --frozen ruff check .

Great work on the architecture refactoring! The code is well-structured and the workflow approach is solid. Address the critical issues above and this will be ready to merge.

- pass the right flags in
- read the right configs
- update README

PR Review: Workflows

This is a significant refactoring with excellent architectural improvements but several critical issues need addressing.

Critical Issues

1. Missing Exception Handling (activities.py:89-98, ai.py:72-73)

  • parse_stories_from_response() could fail on malformed JSON with no recovery
  • client.responses.create() doesn't catch network/API errors
  • get_codebase_context() has no error handling

Per CLAUDE.md, catch specific exceptions (json.JSONDecodeError, ConnectionError, etc.)

2. Resource Leaks (logging.py:23)
File handle never closed - will leak file descriptors

3. Type Safety Issues (ai.py:68-70, activities.py:89)
Missing type hints violate CLAUDE.md requirements:

  • _create_and_parse_response() needs Dict[str, Any]
  • logger parameters missing types
  • parse_stories_from_response() response param untyped

4. Global Mutable State (ai.py:19-20)
Global conversation_id creates thread-safety issues. Use context manager or singleton.

Security Concerns

1. Sensitive Data Logging (ai.py:91-98, 174-185)
Logging full response objects may expose API keys/sensitive content

2. Environment Variable Injection (ai.py:276)
Direct os.environ manipulation could affect other code

3. Token Validation (activities.py:136-141)
No validation that tokens exist - will fail silently if None

Code Quality

1. Line Length Violations
Multiple lines exceed 120 chars. Run: uv run --frozen ruff format . && uv run --frozen ruff check . --fix

2. Incomplete Docstrings
Many functions missing Args, Returns, Raises sections per CLAUDE.md

3. Magic Numbers (activities.py:148, ai.py:22)
Hard-coded values (max_iterations=100) should be constants

4. Code Duplication (ai.py:167-172, 214-219)
Reasoning parameter setup duplicated - extract helper

Test Coverage

Major concern: Zero tests for new modules (activities.py, ai.py, workflow.py, types.py)

  • 250 lines deleted from test_cli.py
  • test_story_machine.py deleted entirely (172 lines)

Need unit tests with mocked API calls and error path testing.

Positive Aspects

  1. Excellent separation: activities, AI layer, workflow orchestration
  2. Good use of structlog for observability
  3. Clean dataclasses and enums in types.py
  4. Great UX with spinner and iterative feedback
  5. Nice reasoning summaries integration

Action Items

Must Fix:

  • Add exception handling per CLAUDE.md
  • Fix resource leak in logging.py
  • Add all type hints
  • Address global state
  • Add token validation
  • Add tests (aim >70% coverage)

Should Fix:

  • Run ruff format/check
  • Complete docstrings
  • Sanitize logging
  • Extract magic numbers

Nice to Have:

  • Parallelize story processing (asyncio.gather)
  • Memoize Settings
  • Clean up doc/workflow.md

Recommendation

Request changes - excellent architecture but needs hardening for production. Prioritize exception handling, resource management, and test coverage.

This PR introduces a significant refactoring that implements a workflow-based approach to story generation, replacing the previous single-pass implementation. The changes represent good progress toward an iterative, feedback-driven system.


✅ Strengths

Code Organization

  • Clean separation of concerns: ai.py, activities.py, workflow.py, and types.py provide clear boundaries
  • Good abstraction: OpenAI API interactions isolated in ai.py makes it easy to swap implementations
  • Structured logging: Using structlog with JSON output provides good observability

Type Safety

  • Proper use of type hints throughout the codebase
  • Dataclasses for structured data (Story, WorkflowInput, FeedbackResponse)
  • Type narrowing with hasattr() checks before attribute access

Workflow Design

  • Iterative feedback loops allow for quality improvement
  • Reasoning summaries provide transparency into AI decision-making
  • Conversation context management enables coherent multi-turn interactions

🔴 Critical Issues

1. Resource Leak in Logging (logging.py:23)

File handle opened but never closed. Use filename string instead of file handle or implement proper cleanup.

2. Missing Error Handling for External Dependencies

  • activities.py:144-149 - No error handling for ask() call (network, auth, API limits)
  • ai.py:72, 187, 238 - OpenAI API calls lack error handling
  • Per CLAUDE.md: Use specific exceptions where possible

3. Token Management (activities.py:136-141)

If user provides GitLab URL but no GITLAB_TOKEN, token is None causing ask() to fail. Add validation with clear error messages.


⚠️ Important Issues

Type Safety

  • activities.py:89 - Missing type annotation on response parameter
  • ai.py:68 - Logger parameter lacks type hint
  • Per CLAUDE.md: Type hints required for all code

Global State (ai.py:19)

conversation_id global mutable state makes testing difficult. Consider passing through workflow context or documenting thread-safety.

Security - Path Traversal (ai.py:62-64)

get_prompt() reads files without validating filename. Add checks to prevent path traversal attacks.


📊 Test Coverage Gaps

Per CLAUDE.md: "New features require tests"

Missing tests for:

  • activities.py (304 lines)
  • ai.py (262 lines)
  • workflow.py (113 lines)
  • types.py (47 lines)
  • logging.py (46 lines)

Only config.py and cli.py have tests. Need async tests using anyio as specified.


🔒 Security Considerations

  1. Secrets in Logs - Request params logged may contain sensitive PRD/tech spec data
  2. Path Traversal - Template loading needs filename validation

🎯 Code Quality

Positive:
✅ Proper Optional usage
✅ Docstrings on public functions
✅ Context managers for resources
✅ Structured logging

Needs Improvement:

  • Magic numbers (max_iterations=100)
  • Duplicate code in workflow loops
  • Mixed concerns (I/O in activities)
  • Settings instantiation repeated (per TODO: should memoize)

✅ Recommendations

Before Merge (Critical)

  1. Fix resource leak in logging.py
  2. Add error handling for external API calls
  3. Add type hints to all function parameters
  4. Fix token validation for GitLab/GitHub
  5. Add path traversal protection

High Priority

  1. Comprehensive test coverage for new modules
  2. Refactor global state
  3. Memoize Settings
  4. Add retry logic for APIs

Medium Priority

  1. Extract duplicate workflow logic
  2. Separate I/O from business logic
  3. Make max_iterations configurable
  4. Add workflow documentation

Overall Assessment

Solid architectural progress with good separation of concerns. Main gaps:

  1. Test coverage - Critical gap
  2. Error handling - Essential for production
  3. Resource management - File leak needs fixing

Recommendation: Address critical issues before merge, prioritize tests in follow-up.

Code Review: Workflows PR

This PR implements a significant refactoring that introduces a workflow-based approach for breaking down PRDs into user stories. The implementation is well-structured with good separation of concerns, but there are several areas that need attention before merging.

Critical Issues

1. Missing Tests for Core Functionality
The PR notes "New implementations don't have tests yet" - this is a critical gap. According to CLAUDE.md, new features require tests. Need unit tests for parse_stories_from_response, problem_break_down, define_acceptance_criteria, enrich_context, and mock-based tests for call_openai_api.

2. Exception Handling Issues

  • activities.py:96 - json.loads can raise JSONDecodeError or KeyError - should catch specific exceptions
  • activities.py:132 - list_tree has no error handling for network operations
  • ai.py:62-63 - File I/O without error handling for OSError/PermissionError

3. Resource Management Issue (logging.py:23)
File handle is never closed - creates a resource leak. Should use context manager.

4. Global Mutable State (ai.py:19)
conversation_id as global state makes testing difficult. Consider dependency injection or at minimum add reset function.

5. Type Safety Issues
Missing type hints for logger parameter in ai.py:67 and response parameter in activities.py:89

Security Concerns

1. Token Exposure Risk
Ensure tokens are never logged and ask-github library is vetted. Consider rate limiting.

2. Input Validation Missing
No validation for repo_url, user comments length, or file content sizes.

Performance Considerations

1. Sequential Story Processing
Stories processed one at a time - intentional but slow for large PRDs. Document performance characteristics.

2. Redundant Settings Creation
Settings() instantiated multiple times. Per TODO in config.py:6, should be memoized.

3. Unnecessary API Calls
Follow-up API call pattern doubles costs - consider more efficient approach.

Code Quality

Positives:

  • Good separation of concerns
  • Comprehensive docstrings
  • Structured logging
  • Clean dataclass usage

Issues:

  • Line length violations (run ruff check)
  • Magic numbers (activities.py:157, logging.py:22, ai.py:132)
  • Spinner thread safety concerns
  • Missing README documentation for workflow

Recommendations

Must Fix Before Merge:

  1. Add comprehensive test coverage
  2. Fix exception handling
  3. Fix resource leak in logging.py
  4. Add missing type hints
  5. Run ruff check and pyright

Should Fix Before Merge:

  1. Implement Settings memoization
  2. Add input validation
  3. Fix global state issue
  4. Document workflow in README
  5. Add network error handling

Recommendation: Request changes - primarily for test coverage and critical bug fixes.

The code shows good architecture but lacks tests which is blocking. Once addressed, this will be solid foundation.

I'm ignoring tests for this work, because it's very likely going to be rewritten in another form, and most of this code will be discarded. The workflow was created as a stepping stone. Similarly for handling exceptions, currently any exception will loudly just stop the program, I think.
