Details

refactor: reorganize into monorepo with separate subprojects

Structure webber into three independent subprojects:
- webber-api/: FastAPI backend server with all agent code
- webber-cli/: Standalone CLI client (renamed from cli/ to webber_cli/)
- webber-sandbox/: Test project for functional testing

Key changes:
- Each subproject has its own .venv (Python 3.12+)
- Added sandbox.sh for managing test project templates
- Created sandbox-templates/ with calculator-cli and empty starter
- Updated CI/CD for prefixed tags (api/v*, cli/v*)
- Added comprehensive AGENTS.md with operational instructions
- Added gitignore filtering to glob and grep tools
- Created pyproject.toml for each subproject

Calculator CLI - Tasks for Webber

A simple calculator with intentional bugs and missing features for testing Webber's capabilities.

Bugs to Fix

High Priority

Division by zero - operations.py:divide() crashes when dividing by zero instead of returning an error
Invalid operation name - main.py:get_operation() raises KeyError for unknown operations instead of helpful error message

Medium Priority

Power function broken - operations.py:power() doesn't handle negative exponents or fractional exponents correctly
No input validation - main.py doesn't validate that command-line arguments are valid numbers

Missing Tests

Add TestDivide class with tests for:
- Normal division
- Division by zero (should test error handling once bug is fixed)
- Division with negative numbers
Add TestPower class with tests for:
- Positive integer exponents
- Zero exponent (should return 1)
- Negative exponents
Complete existing test classes:
- test_add_zero
- test_add_floats
- test_subtract_negative
- test_multiply_by_zero

Features to Add

Expose power operation - Add 'pow' to the operations dictionary in main.py
Add modulo operation - Implement modulo(a, b) in operations.py
Add --verbose flag - Show step-by-step calculation
Add history command - Track and display recent calculations
Add REPL mode - Interactive calculator loop

Code Quality

Add type hints to all functions
Add docstrings following Google style
Fix any linting errors (run ruff check src/)

How to Run

# Setup
python3.12 -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt

# Run calculator
python -m calculator.main 10 5 add
python -m calculator.main 10 5 div

# Run tests
pytest tests/ -v

# See failing tests (division by zero)
python -m calculator.main 10 0 div
