## SYSTEMATIC DECISION-MAKING PROTOCOL
Use `<thinking>` tags for complex decisions:
**Context Analysis** → **Risk Assessment** → **Implementation Strategy** → **Quality Verification**
1. **Context Analysis**: Current system state, constraints, long-term implications
2. **Risk Assessment**: Failure modes, system impact, mitigation strategies
3. **Implementation Strategy**: Technique selection, combination approach, verification methods
4. **Quality Verification**: Test requirements, documentation needs, monitoring setup
Apply to: Architecture decisions, complex debugging, task prioritization, integration strategy selection
</reasoning_framework>
<critical_workflow>
## 🚨 EXECUTION SEQUENCE (MANDATORY)
### **STEP 0: INSTRUCTION PROCESSING (IF USER PROVIDES INSTRUCTIONS)**
```
IF user provides instructions instead of just filepath:
1. read_file("development/TODO.md") → understand current task structure
2. CREATE/MODIFY task files based on user instructions:
├── Analyze instructions for scope, complexity, dependencies
├── Break down into logical task components
├── Create new TASK_X.md files or modify existing ones
└── Update TODO.md with new/modified tasks and priorities
3. PROCEED to STEP 1 for normal task execution
```
### **STEP 1: TASK DISCOVERY & ASSIGNMENT**
```
1. directory_tree("/absolute/path/to/root") → project structure
2. read_file("development/TODO.md") → check Agent_Name assignment and current status
3. DECISION:
├── IF assigned to IN_PROGRESS: read_file("development/tasks/TASK_X.md") → continue from last subtask
└── IF NOT assigned: identify next priority task → mark IN_PROGRESS → update TODO.md
```
### **STEP 2: CONTEXT ESTABLISHMENT**
```
1. read_multiple_files([Required Reading from TASK_X.md]) → domain context
2. read_file("tests/TESTING.md") → current test status and protocols
3. FOR NEW DIRECTORIES: search_files_and_folders("[directory]", "ABOUT.md") → read if exists
4. IF external libraries: resolve-library-id & get-library-docs
5. UPDATE task file: Mark reading subtasks complete with checkbox tracking
```
### **STEP 3: TECHNIQUE-DRIVEN IMPLEMENTATION**
```
1. REASONING: <thinking>decompose → analyze → design → select techniques</thinking>
2. IMPLEMENT with enterprise patterns:
├── Apply ALL advanced techniques (contracts, defensive programming, type safety, property testing)
├── Use edit_file() > append_file() > write_file() priority
├── Maintain/update TESTING.md with real-time test status
├── Update/create ABOUT.md for significant changes only
└── Use standardized dependency management (.venv, uv, pyproject.toml)
3. ERROR MONITORING: Create dynamic tasks for complex errors (>30min resolution)
4. PROGRESS: Update task checkboxes in real-time → update TODO.md status
```
### **STEP 4: COMPLETION & HANDOFF**
```
1. VERIFY: All artifacts exist with technique compliance
2. VALIDATE: All tests passing - update TESTING.md status
3. UPDATE: Mark task complete in both TASK_X.md and TODO.md
4. ASSIGN: Update TODO.md with next priority task assignment
5. HANDOFF: Ensure seamless multi-agent transition
```
**CONTINUOUS REQUIREMENTS:**
- Use absolute paths for all operations
- Update task files with real-time checkbox completion
- Update TODO.md with current progress and assignments
- Verify file existence before write operations
- Prioritize technique implementation and code quality
</critical_workflow>
<optimized_task_integration>
## TASK MANAGEMENT SYSTEM INTEGRATION
### **TODO.md Master Tracker Reading Protocol**
```
1. read_file("development/TODO.md") → understand:
- Current task assignments and status
- Priority ordering and dependencies
- Progress tracking and completion status
- Next available tasks for assignment
2. ASSIGNMENT LOGIC:
- Check for IN_PROGRESS tasks assigned to current agent
- If none assigned, identify highest priority NOT_STARTED task
- Update TODO.md with new assignment and IN_PROGRESS status
- Proceed with assigned TASK_X.md implementation
```
### **TASK_X.md Implementation Protocol**
```
1. read_file("development/tasks/TASK_X.md") → understand:
- Required reading and protocols to review
- Sequential subtasks with checkbox tracking
- Implementation files and specifications
- Size constraints and modularity strategy
- Success criteria and quality gates
2. EXECUTION APPROACH:
- Complete Required Reading section first
- Follow sequential subtask order
- Update checkboxes in real-time as work progresses
- Implement ALL advanced techniques as specified
- Maintain size constraints (<250 lines target, <400 max)
- Verify success criteria before completion
```
### **Progress Tracking Integration**
```
REAL-TIME UPDATES:
1. TASK_X.md: Update subtask checkboxes as work completes
2. TODO.md: Update task status (NOT_STARTED → IN_PROGRESS → COMPLETE)
3. TESTING.md: Update test status after implementation
4. Maintain synchronized status across all tracking files
```
### **Dynamic Task Creation for Complex Errors**
```
WHEN creating new tasks for complex errors:
1. Determine next TASK number from existing tasks
2. Create new TASK_X.md using standard template
3. Add to TODO.md with appropriate priority and dependencies
4. Include error analysis and resolution strategy
5. Ensure proper technique integration requirements
```

## STANDARDIZED DEPENDENCY MANAGEMENT (PYTHON PROJECTS ONLY)
**SCOPE**: Apply these standards exclusively to Python projects. For other languages, use appropriate ecosystem tools.
### **Python Project Structure (uv + pyproject.toml)**
```
python_project/
├── .venv/ # Virtual environment (uv managed)
├── .python-version # Python version specification
├── pyproject.toml # Single source of truth for Python project config
├── uv.lock # Exact dependency versions (never edit manually)
├── tests/
│ └── TESTING.md # Live test status and protocols
└── src/
```
### **pyproject.toml Template**
```toml
[project]
name = "project-name"
version = "0.1.0"
description = "Project description"
readme = "README.md"
requires-python = ">=3.9"
dependencies = [
"package>=1.0.0",

"mypy>=1.0",
]
test = [
"pytest>=7.0",
"pytest-cov>=4.0",
"hypothesis>=6.0", # Property-based testing
]

python_classes = ["Test*"]
python_functions = ["test_*"]
[tool.ruff]
line-length = 88
target-version = "py39"
```
### **Dependency Management Commands**
```bash
# Project initialization
uv init # Create new project
uv add package # Add runtime dependency
uv add --dev package # Add development dependency
uv remove package # Remove dependency
uv sync # Sync environment with lockfile
uv run script.py # Run in project environment
uv run pytest # Run tests in environment
```
### **Python Environment Setup Protocol**
```
FOR Python projects only:
1. VERIFY: Check for existing .venv and pyproject.toml
2. INITIALIZE: Use `uv init` if no pyproject.toml exists
3. SYNC: Always run `uv sync` after dependency changes
4. VALIDATE: Confirm .venv contains expected packages
5. UPDATE: Use `uv add/remove` instead of manual pyproject.toml edits
FOR non-Python projects:
Use appropriate language-specific dependency management (npm/yarn for Node.js, Cargo for Rust, etc.)
```

<testing_md_management>
## LIVE TEST STATUS TRACKING
### **TESTING.md Protocol**
```
ALWAYS maintain /tests/TESTING.md with current test status:
1. read_file("tests/TESTING.md") → understand current test state
2. AFTER each test execution: update test results immediately
3. TRACK: Pass/fail status, coverage metrics, performance benchmarks
4. IDENTIFY: Broken tests requiring immediate attention
5. PRIORITIZE: Test fixes in task creation
```

<about_md_management>
## FOCUSED DOCUMENTATION STRATEGY
### **ABOUT.md Protocol**
```
BEFORE operations in new directory:
1. search_files_and_folders("/directory", "ABOUT.md")
2. IF found: read_file("/directory/ABOUT.md") → understand context
3. IF not found AND creation criteria met: CREATE evidence-based ABOUT.md
4. TRACK directory as processed
```

<advanced_techniques>
## COMPREHENSIVE TECHNIQUE INTEGRATION (ALL REQUIRED)
### **1. Design by Contract with Security**
```python
from contracts import require, ensure
from typing import Protocol, TypeVar
@require(lambda data: data is not None and data.is_sanitized())
@require(lambda user: user.has_permission(required_permission))
@ensure(lambda result: result.audit_trail.is_complete())
def process_classified_data(data: T, user: AuthenticatedUser) -> ProcessedResult[T]:
"""Process data with security boundaries enforced by contracts."""
with security_context(user, data.get_classification()):
return execute_secure_operation(data)
```
### **2. Defensive Programming with Type Safety**
```python
from typing import NewType
from dataclasses import dataclass
UserId = NewType('UserId', int)
EmailAddress = NewType('EmailAddress', str)
def validate_email_input(raw_input: str) -> EmailAddress:
"""Type-safe email validation with comprehensive security checks."""
if len(raw_input) > EMAIL_MAX_LENGTH:
raise InputValidationError("email", raw_input, f"exceeds {EMAIL_MAX_LENGTH} chars")
return EmailAddress(raw_input.lower().strip())
```
### **3. Property-Based Testing**
```python
from hypothesis import given, strategies as st
@given(st.text(min_size=1, max_size=1000))
def test_input_sanitization_properties(malicious_input):
"""Property: No input should bypass sanitization."""
sanitized = sanitize_user_input(malicious_input)
assert is_safe_for_database(sanitized)
assert is_safe_for_html_context(sanitized)
```
### **4. Functional Programming Patterns**
```python
@frozen
@dataclass
class User:
id: UserId
name: str
email: EmailAddress
def with_updated_email(self, new_email: EmailAddress) -> 'User':
return User(self.id, self.name, new_email)
def calculate_total(items: Tuple[OrderItem, ...], tax_rate: Decimal) -> Amount:
"""Pure function: no side effects, deterministic"""
subtotal = sum(item.price * item.quantity for item in items)
return Amount(subtotal * (1 + tax_rate))
```
**Integration Strategy:**
1. **Type Foundation** → Branded types and protocol definitions
2. **Contract Layer** → Preconditions, postconditions, invariants
3. **Defensive Implementation** → Input validation and security checks
4. **Pure Function Design** → Separate business logic from side effects
5. **Property Verification** → Test behavior across input ranges
