phase: 02-bot-core
plan: 01
subsystem: bot
tags: [telegram, python-telegram-bot, async, configuration]
# Dependency graph
requires:
- phase: 01-foundation/01-03
provides: Async database session management (init_db, create_tables, close_db)
provides:
- Bot entry point with Application lifecycle
- Configuration loading from environment
- Handler registration pattern
affects: [02-02-handlers, 03-project-crud]
# Tech tracking
tech-stack:
added: [python-telegram-bot]
patterns: [ApplicationBuilder with lifecycle hooks, module-level config singleton]
key-files:
created:
- src/moai/bot/config.py
- src/moai/bot/main.py
modified:
- src/moai/bot/handlers/__init__.py
key-decisions:
- "Module-level config reference for post_init callback access"
- "Config stored in bot_data for handler access"
- "Empty register_handlers as extension point for future handlers"
patterns-established:
- "Bot lifecycle: post_init for DB setup, post_shutdown for cleanup"
- "Environment config with BotConfig.from_env() pattern"

# Phase 02-01: Bot Infrastructure Summary
**Telegram bot entry point with ApplicationBuilder, config loading, and handler registration pattern**
## Performance
- **Duration:** 2 min
- **Started:** 2026-01-16T15:34:55Z
- **Completed:** 2026-01-16T15:37:27Z
- **Tasks:** 3
- **Files modified:** 3
## Accomplishments
- BotConfig dataclass loading configuration from environment variables
- Bot main.py with ApplicationBuilder and database lifecycle hooks
- Handler registration pattern ready for incremental handler addition
## Task Commits
Each task was committed atomically:
1. **Task 1: Create bot configuration module** - `4381e12` (feat)
2. **Task 2: Create bot main.py with Application setup** - `c3a849b` (feat)
3. **Task 3: Create handlers package structure** - `0a81855` (feat)
## Files Created/Modified
- `src/moai/bot/config.py` - BotConfig dataclass with from_env() loading BOT_TOKEN, ALLOWED_USERS, DATABASE_URL, LOG_LEVEL
- `src/moai/bot/main.py` - Bot entry point with ApplicationBuilder, post_init/post_shutdown hooks, register_handlers call
- `src/moai/bot/handlers/__init__.py` - register_handlers function placeholder for future handler registration
## Decisions Made
- Used module-level `_config` variable for post_init callback to access config (simpler than passing through Application)
- Store config in `app.bot_data["config"]` for handlers to access user settings
- Keep register_handlers as empty placeholder rather than removing it - cleaner extension point
## Deviations from Plan
None - plan executed exactly as written.
## Issues Encountered
None
## Next Phase Readiness
- Bot infrastructure complete, ready for handler implementation
- Ready for 02-02: /help and /status command handlers
- Database lifecycle integrated with bot startup/shutdown
