cd freebee
npm install
npm run build

With Docker

git clone https://github.com/your-org/freebee.git
cd freebee

Configuration

Copy .env.example to .env and fill in the values:

cp .env.example .env

Required Variables

Variable	Description
MATRIX_HOMESERVER_URL	Your Matrix homeserver (e.g., https://matrix.example.com)
MATRIX_BOT_USER_ID	Bot's full user ID (e.g., @freebee:example.com)
MATRIX_ACCESS_TOKEN	Bot's access token (or set MATRIX_BOT_PASSWORD instead)

Authentication

You can authenticate the bot in two ways:

1. Access token only — set MATRIX_ACCESS_TOKEN. If it expires, the bot exits.
2. Password (recommended) — set MATRIX_BOT_PASSWORD. The bot validates the token on startup and automatically obtains a new one via password login if it's expired or missing. The new token is persisted to .env.

Both can be set simultaneously for maximum resilience.

Recommended Variables

Variable	Default	Description
MATRIX_BOT_PASSWORD	(empty)	Bot account password for automatic token renewal
BOT_ROOMS	(empty)	Comma-separated room IDs for scheduled posts
BOT_ADMIN_USERS	(empty)	Comma-separated admin user IDs
BOT_PREFIX	!	Command prefix
DATA_DIR	./data	Directory for database, crypto store, and logs
LOG_LEVEL	info	Logging level (debug, info, warn, error)
BOT_DEFAULT_CITY	(empty)	Default city for concert digests and location features

API Keys

Variable	Required For	How to Get
RAWG_API_KEY	!releases, daily game releases post	rawg.io/apidocs (free)
WORDNIK_API_KEY	Word of the Day post	developer.wordnik.com (free)
CALENDARIFIC_API_KEY	Holiday data (Western + Asian holidays)	calendarific.com (free tier)
OPENWEATHER_API_KEY	!weather command	openweathermap.org (free tier)
FINNHUB_API_KEY	!stock command	finnhub.io (free, 60 calls/min)
BANDSINTOWN_API_KEY	!concerts command	bandsintown.com (free)
TMDB_API_KEY	!movie, !tv commands	themoviedb.org (free)

HebCal (Jewish calendar), Aladhan (Islamic calendar), Jikan/MAL (anime), OpenTDB (trivia), Wikipedia, and Free Dictionary are free and require no API keys.

Optional: Self-hosted Services

Variable	Default	Description
LIBRETRANSLATE_URL	(empty)	URL for self-hosted LibreTranslate instance (e.g., http://localhost:5000)
OLLAMA_HOST	(empty)	Ollama endpoint for LLM classifier (e.g., http://localhost:11434)
OLLAMA_MODEL	(empty)	Ollama model name (e.g., qwen2.5:1.5b)
LLM_SAMPLE_RATE	0.15	Fraction of non-keyword messages randomly sampled for LLM classification (0.0–1.0)
ASIAN_HOLIDAY_COUNTRIES	JP,CN,KR,IN,TH,VN,TW,PH	Comma-separated country codes for Asian holiday data

LLM features (profanity/insult/sentiment/gratitude detection, smart WOTD validation) are only active when both OLLAMA_HOST and OLLAMA_MODEL are set. Leave them blank to disable. The classifier uses a 16k context window, a 30-second request timeout, and exponential backoff (5s–5min) when Ollama is unreachable. When active, the LLM replaces keyword-based thanks detection with sarcasm-aware gratitude detection for the reputation system.

Rate Limits

Getting a Matrix Access Token

1. Log into your bot's Matrix account via Element or another client
2. Go to Settings > Help & About > Advanced and copy the access token
3. Alternatively, use the Matrix client-server API:

   curl -X POST "https://your-homeserver/_matrix/client/v3/login" \
     -H "Content-Type: application/json" \
     -d '{"type":"m.login.password","user":"freebee","password":"your-password"}'
   

4. Copy the access_token from the response

Or just set MATRIX_BOT_PASSWORD and let the bot handle token management automatically.

Commands

All commands use the configured prefix (default: !). Use !help to get a full command list sent to your DMs.

XP & Leveling

Command	Description
!rank [@user]	Show XP, level, and progress bar
!leaderboard [n]	Top N users by XP (default 10, max 25)

XP is earned passively: 10 XP per message with a 30-second cooldown to prevent farming. The level curve is linear: level N requires N x 100 total XP. When a user levels up, the bot announces it with a random Twinbee/Parodius-themed power-up message (bell combos, laser modes, shield activations, etc.).

Reputation

Command	Description
!rep [@user]	Show reputation score
!repboard	Top 10 by reputation

Reputation is granted automatically when the bot detects natural "thanks" messages directed at another user (e.g., "thanks @user:server.com", "ty @user:server.com"). There's a 24-hour cooldown per giver/receiver pair. The bot reacts with a checkmark to acknowledge.

When the LLM classifier is active, keyword-based detection is replaced with sarcasm-aware gratitude detection — sarcastic thanks like "thanks for nothing" won't grant rep.

Receiving reputation also grants 5 bonus XP.

Statistics

Command	Description
!stats [@user]	Full message metrics (words, links, images, questions, etc.)
!rankings [category]	Leaderboard by category
!personality [@user]	Your community archetype

Valid ranking categories: messages, words, links, images, questions, emojis, streak

!unremind <id>	Cancel a reminder by ID

Time parsing examples:

• !remindme in 30 minutes check the oven
• !remindme tomorrow at 3pm meeting with team
• !remindme next friday submit report

Reminders are checked every 30 seconds.

User Settings & Tools

Command	Description
!settz <city|IANA>	Set your timezone (e.g., !settz Tokyo, !settz America/New_York)
!mytz	Show your timezone and current local time
!timezone list	World clock for everyone in the room who has set a timezone
!quote [@user]	Random starred quote (star a message to save it)

Presence

Command	Description
!away [message]	Set away status with optional message
!afk [message]	Set AFK status with optional message
!back	Clear away/afk status
!whois @user	Full profile card (status, timezone, now playing, rep, level, streak)

Away/AFK status auto-clears silently when the user sends any message.

Weather

Command	Description
!weather <city>	Current weather for a city name (e.g., !weather Tokyo)
!weather <zip[,CC]>	Weather by zip/postal code — defaults to US, append country code for others (e.g., !weather 10115,DE)
!weather @user	Weather for a user's location, derived from their !settz timezone

Weather uses the OpenWeatherMap Geocoding API to resolve locations before fetching conditions. For ambiguous city names (e.g., "Springfield"), US matches are preferred. Output includes current conditions, temperature in both °C and °F, feels-like temperature, humidity, and wind speed.

Fun

Command	Description
!roll [N]d<sides>[+/-mod]	Dice roller (e.g., !roll d20, !roll 2d6+3)

Answer by typing the letter (A/B/C/D) or True/False. First correct answer wins. Scoring is time-weighted: full 100 points within 3 seconds, decaying linearly to 0 at timeout (default 20 seconds, configurable via TRIVIA_TIMEOUT_SECONDS).

Threading: The first !trivia command in a room creates a dedicated trivia thread. All questions, answers, and subcommands (scores, categories, fastest, stop) are posted within that thread to keep the main room clean. New questions can be started from the main room (with optional category/difficulty), but answers and subcommands must be typed in the thread.

!tldr [n]	Summarize the last N messages (default: all buffered, max 50) for someone catching up

The classifier also provides emoji reactions as real-time feedback (with automatic retry on connection failures):

• Profanity: 🫣 (mild), 😲 (moderate), 🤬 (severe)
• Insults: 🖕 (bot targeted), 🎯 (direct), 💨 (indirect)
• WOTD: 📖 (correct usage), 🤔 (incorrect)
• Sentiment (when no other reaction applies): random emoji from pools for happy, sad, angry, excited, funny, love, and scared

!vibe and !tldr share a rolling in-memory buffer of the last 50 text messages per room. The buffer is not persisted — it resets on restart. At least 10 messages are required before either command works.

Passive Features

These features run silently on every message. The bot never announces passive tracking — commands are the only reveal mechanism.

Feature	Description
XP tracking	Grants 10 XP per message (30s cooldown); announces level-ups with Twinbee/Parodius-themed messages
Stats tracking	Counts words, links, images, questions, emojis, message length, hourly/daily distributions
Streak tracking	Tracks daily activity and consecutive-day streaks
First! tracking	Records who posts the first message each day per room
Thanks detection	Detects thank-you messages and grants reputation
WOTD detection	Grants 25 bonus XP for using the word of the day
Achievement evaluation	Checks all 32 achievements on every message
Keyword alerts	DMs users when watched keywords appear
Quote saving	Star-reacting a message saves it as a quote
Presence tracking	Updates last-seen time; auto-clears away/afk on message
Markov corpus	Collects non-command messages for text generation (capped at 10,000 per user per room)
URL previews	Extracts og:title and og:description from shared links (if FEATURE_URL_PREVIEW=true)
Welcome detection	Greets first-time users with 25 XP
Reaction tracking	Logs who gives reactions to whom and which emoji, for !emojiboard
Conversation milestones	Tracks total room messages, celebrates at 1k, 5k, 10k, 25k, 50k, 100k, 250k, 500k, and 1M
LLM classification	Classifies profanity (multilingual), insults, sentiment, gratitude, and WOTD correctness via Ollama (if configured). Uses keyword pre-filter, non-ASCII detection, and random sampling (LLM_SAMPLE_RATE) to catch profanity in any language. Provides emoji reactions as feedback. Includes exponential backoff and robust JSON repair for small model output.
Trivia answer detection	Intercepts letter answers (A/B/C/D) when a question is active (within the trivia thread)

---

Scheduled Posts

The bot posts automated content to rooms listed in BOT_ROOMS.

Word of the Day (default: 08:00 UTC)

Posts a word from Wordnik with its definition, part of speech, and an example sentence. Users who use the word in a message that day earn 25 bonus XP (once per user per day). Use !wotd at any time to see the current word without waiting for the scheduled post.

Holidays & Observances (default: 07:00 UTC)

Posts a morning summary combining data from multiple calendar sources:

• Calendarific (US) — civic and Western holidays
• Calendarific (Asian) — holidays from Japan, China, South Korea, India, Thailand, Vietnam, Taiwan, and Philippines (configurable via ASIAN_HOLIDAY_COUNTRIES)
• HebCal — Jewish calendar events and Hebrew date
• Aladhan — Islamic holidays and Hijri date

The post includes a multi-calendar date header (Gregorian + Hebrew + Hijri), sections for religious observances, Asian holidays (with country labels), and other observances, plus a featured highlight that prefers non-Western holidays when available. Use !holidays week or !holidays month to look ahead — range queries are cached for 1 hour to avoid excessive API calls.

Birthday Announcements (default: 07:05 UTC)

Checks all stored birthdays against today's date. Posts a birthday message to each relevant room, DMs the birthday person, and grants 100 bonus XP. If year is stored, includes the person's age.

Game Releases (default: 19:00 UTC)

Posts today's game releases from RAWG with platform info. Cross-references the HLTB cache to append estimated playtimes when available. Also checks the release watchlist and sends DM notifications to users watching for specific games.

Anime Airings (default: 19:30 UTC)

Posts a summary of watchlisted anime airing today. DMs users whose watchlisted shows have new episodes.

Movie & TV Releases (default: 20:00 UTC)

Posts watchlisted movie and TV releases for today. DMs users when their watchlisted titles release.

Concert Digest (default: 10:00 UTC, Sundays only)

Posts "This Week in Live Music" with concerts in the next 7 days for watched artists. DMs users watching artists with upcoming shows. Only fires on Sundays.

Prefetch (default: 00:05 UTC)

Fetches API data for Holidays and WOTD ahead of their scheduled post times and caches it in the daily_prefetch table. This ensures the actual post jobs have no network dependency and can deliver content even if the APIs are temporarily down. Each source is fetched independently — one failure doesn't block the others.

Nightly Maintenance (default: 00:15 UTC)

Prunes old data to prevent database bloat. Retention policies: llm_classifications (30 days), xp_log (30 days), command_usage (7 days), rep_cooldowns (2 days), daily_prefetch (3 days), all cache tables (7–30 days depending on type), and shade_log (30 days). Runs after prefetch so fresh data is never pruned.

Urban Dictionary	!urban	Slang/term definitions	No
Ollama	LLM classifier	Profanity/insult/WOTD classification (self-hosted)	No

All API calls are wrapped in try/catch. If any API is down, the bot logs a warning and skips that feature — it never crashes over a failed API call.

Plugin System

Every plugin extends the Plugin abstract class and implements:

• name — plugin identifier
• commands — list of command definitions
• onMessage(ctx) — called for every message (both passive tracking and command handling)
• onReaction(ctx) — optional, called for reactions (e.g., star → quote)

Plugins interact with Matrix through the IMatrixClient interface defined in base.ts. The BotClient class in matrix-client.ts wraps matrix-js-sdk and implements this interface, allowing SDK changes without touching plugin code.

Plugins are registered with PluginRegistry, which dispatches messages and reactions to all plugins in order. XP is registered first since other plugins depend on it. Welcome is registered last so it can list all commands via !help.

Key Design Decisions

• Almost all passive tracking is silent. The bot never announces streaks, First!, keyword watches, or achievements — commands are the only reveal mechanism. The one exception is level-ups, which get a celebratory Twinbee/Parodius-themed announcement.
• XpPlugin.grantXp() is the single XP entry point — Birthday, WOTD, Trivia, Welcome, Reputation, and LLM classifier all route through it.
• LLM features are fully optional. Gated by OLLAMA_HOST and OLLAMA_MODEL — both must be set for classifier to activate. All LLM commands return "not configured" otherwise. The classifier queue is capped at 50 items, requests time out after 30 seconds, a 16k context window is configured for Ollama, and exponential backoff (5s–5min) prevents hammering a down Ollama instance. When active, LLM replaces keyword-based rep granting with sarcasm-aware gratitude detection.
• Rate limits are centralized in RateLimitsPlugin. Paid-API commands call checkLimit() before requests. Admins bypass all limits.
• Stats are computed from stored primitives, not pre-aggregated. !rankings does live SQL queries.
• Markov corpus is capped at 10,000 rows per user per room. Oldest pruned on overflow.
• URL previews are text-only — no image reposting, one clean line of description.
• Presence auto-clears on any message from an away user. Silent.
• !help always DMs — never floods the room with a command list.
• Trivia is one-at-a-time per room and runs in a dedicated Matrix thread. Concurrent sessions not supported.
• Concert digest is Sunday-only — job fires daily, handler checks day-of-week internally.
• The scheduler reads config from the DB each tick so !schedule changes take effect without restart.

Troubleshooting

Bot won't start

• "Missing required env vars" — Make sure MATRIX_HOMESERVER_URL and MATRIX_BOT_USER_ID are set. Provide either MATRIX_ACCESS_TOKEN or MATRIX_BOT_PASSWORD.
• "Database not initialized" — The DATA_DIR directory must be writable. Check permissions.
• Native module errors — Run npm rebuild after switching Node.js versions. better-sqlite3 has native bindings.
• "Login failed" — If using password auth, verify the password is correct. Special characters in passwords are handled properly by the bot (unlike manual curl commands).

Bot doesn't respond to messages

• Verify the bot has joined the room. The bot auto-joins on invite, but check its room list.
• Check that the bot's user ID in MATRIX_BOT_USER_ID exactly matches the account the access token belongs to (the bot ignores its own messages using this ID).
• Make sure messages use the correct prefix (default !).
• Check data/freebee.log for errors.

Bot can't decrypt messages

• The crypto store at DATA_DIR/crypto-js/ and device identity at DATA_DIR/device.json must be persisted across restarts. Losing them means the bot creates a new device and must re-establish sessions.
• If using Docker, make sure the ./data volume mount is working correctly.
• If the crypto store is corrupted, run with CRYPTO_RESET=true to cleanly wipe and re-establish keys. This deletes the old device from the server, wipes the local crypto store and device.json, and sends a key exchange announcement to BOT_ROOMS. The flag is single-use — remove it after the reset.
• After a crypto reset, other users' clients will need to exchange keys with the bot's new device. This happens automatically — matrix-js-sdk handles key gossiping, device tracking, and session management without manual intervention.

Scheduled posts aren't working

• Make sure BOT_ROOMS is set with at least one room ID.
• Verify API keys are set for the relevant feature (WORDNIK_API_KEY for WOTD, RAWG_API_KEY for releases, CALENDARIFIC_API_KEY for holidays, etc.).
• Schedule times are in UTC. Use !schedule to check/adjust.
• The scheduler checks every 60 seconds, so there may be up to a 60-second delay.

Reminders don't fire

• Reminders are checked every 30 seconds. Very short reminders (< 30 seconds) may be slightly delayed.
• Reminder times are stored as UTC. If your times seem off, set your timezone with !settz.

HLTB lookups fail

• The howlongtobeat library scrapes the HLTB website. It can break when the site changes. Check for library updates: npm update howlongtobeat.
• Results are cached for 24 hours to reduce scraping load.

Weather returns wrong city

• The weather command uses OpenWeather's Geocoding API to resolve locations. For ambiguous city names (e.g., "Springfield"), it prefers US matches.
• To specify a country, append a country code: !weather Springfield,GB.
• Zip codes default to US. For other countries, append the code: !weather 10115,DE.

LLM features show "not configured"

• Both OLLAMA_HOST and OLLAMA_MODEL must be set and non-empty.
• Verify Ollama is running and accessible at the specified host.
• The bot connects to Ollama via HTTP — no authentication is needed.
• The classifier includes robust JSON repair for small models that produce malformed output (trailing commas, single quotes, unquoted keys, markdown fences, etc.).

Rate limit errors

• Users get a quota message when they exceed their daily limit for rate-limited commands.
• Admins (BOT_ADMIN_USERS) bypass all rate limits.
• Limits reset at midnight UTC.

High memory usage

• SQLite WAL mode can accumulate large WAL files under heavy write load. The database checkpoints automatically, but you can force one by restarting the bot.

Permission errors in Docker

• The data/ directory must be writable by the container's user. If you see permission errors:

  chmod -R 777 ./data  # or match the container's UID

Backup & Recovery

What to back up

1. DATA_DIR/crypto-js/ and DATA_DIR/device.json — The bot's E2EE device identity and crypto state. Losing these means the bot creates a new device and must re-establish all sessions. This is the most critical data to back up.
2. DATA_DIR/freebee.db — All user data, stats, achievements, reminders, quotes, watchlists, Markov corpus, etc.
3. .env — Your configuration (contains secrets, store securely).

Backup script example

#!/bin/bash
BACKUP_DIR="/backups/freebee/$(date +%Y-%m-%d)"
mkdir -p "$BACKUP_DIR"
cp -r ./data/crypto-js "$BACKUP_DIR/"
cp ./data/device.json "$BACKUP_DIR/"
cp ./data/freebee.db "$BACKUP_DIR/"
echo "Backup complete: $BACKUP_DIR"

Recovery

1. Stop the bot
2. Restore crypto-js/ directory, device.json, and freebee.db to the DATA_DIR location
3. Start the bot

If only the database is lost (crypto store intact), the bot will create a fresh database but retain its device identity. All user data will be reset.

If only the crypto store is lost (database intact), delete the old crypto-js/ directory and device.json, restart the bot, and it will create a new device identity. User data is preserved. Other clients will automatically share keys with the new device as they send messages.
