From 08815a3dd04688c384a05f60cad8c927f668063d Mon Sep 17 00:00:00 2001 From: latte Date: Tue, 27 Jan 2026 18:58:56 +0100 Subject: [PATCH 01/12] WIP: Minimal bot refactor - new files and core updates - Created config.yml template with conservative AI limits - Created owner.py cog (status, reload, ping commands) - Created config_loader.py service for YAML config - Created ai_rate_limiter.py for AI cost control - Updated bot.py to load only 3 cogs (automod, ai_moderation, owner) - Simplified config.py (removed unused settings) - Deleted unnecessary cogs, services, models - Updated models/__init__.py Next: Update automod and ai_moderation cogs --- config.yml | 61 +++ src/guardden/bot.py | 148 ++---- src/guardden/cli/__init__.py | 1 -

Bot sends verification challenge via DM (or channel if DMs disabled) -3. Member completes the challenge -4. Bot assigns the verified role -5. Member gains access to the server - -## AI Moderation - -GuardDen supports AI-powered content moderation using either Anthropic's Claude or OpenAI's GPT models. - -### Setup - -1. Set the AI provider in your environment: - ```bash - GUARDDEN_AI_PROVIDER=anthropic # or "openai" - GUARDDEN_ANTHROPIC_API_KEY=sk-ant-... # if using Claude - GUARDDEN_OPENAI_API_KEY=sk-... # if using OpenAI - ``` - -2. Enable AI moderation per server: - ``` - !ai enable - !ai sensitivity 50 # 0=lenient, 100=strict - !ai nsfw true # Enable NSFW image detection - ``` - -### Content Categories - -The AI analyzes content for: -- **Harassment** - Personal attacks, bullying -- **Hate Speech** - Discrimination, slurs -- **Sexual Content** - Explicit material -- **Violence** - Threats, graphic content -- **Self-Harm** - Suicide/self-injury content -- **Scams** - Phishing, fraud attempts -- **Spam** - Promotional, low-quality content - -### How It Works - -1. Messages are analyzed by the AI provider -2. Results include confidence scores and severity ratings -3. Actions are taken based on guild sensitivity settings -4. All AI actions are logged to the mod log channel - -### NSFW-Only Filtering Mode (Enabled by Default) - -**Default Behavior:** -GuardDen is configured to only filter sexual/NSFW content by default. This allows communities to have mature discussions about violence, politics, and controversial topics while still maintaining a "safe for work" environment. - -**When enabled (DEFAULT):** -- โœ… **Blocked:** Sexual content, nude images, explicit material -- โŒ **Allowed:** Violence, harassment, hate speech, self-harm content - -**When disabled (strict mode):** -- โœ… **Blocked:** All inappropriate content categories - -**To change to strict mode:** -```yaml -# Edit config/guilds/guild-.yml -ai_moderation: - nsfw_only_filtering: false -``` - -This default is useful for: -- Gaming communities (violence in gaming discussions) -- Mature discussion servers (politics, news) -- Communities with specific content policies that allow violence but prohibit sexual material - -### Public In-Channel Warnings (Disabled by Default) - -**IMPORTANT PRIVACY NOTICE**: In-channel warnings are **PUBLIC** and visible to all users in the channel, NOT private messages. This is a Discord API limitation. - -When enabled and users have DMs disabled, moderation warnings are sent as temporary public messages in the channel where the violation occurred. - -**How it works:** -1. Bot tries to DM the user about the violation -2. If DM fails (user has DMs disabled): - - If `send_in_channel_warnings: true`: Sends a **PUBLIC** temporary message in the channel mentioning the user - - If `send_in_channel_warnings: false` (DEFAULT): Silent failure, no notification sent - - Message includes violation reason and any timeout information - - Message auto-deletes after 10 seconds -3. If DM succeeds, no channel message is sent - -**To enable in-channel warnings:** -```yaml -# Edit config/guilds/guild-.yml -notifications: - send_in_channel_warnings: true -``` - -**Considerations:** - -**Pros:** -- Users are always notified of moderation actions, even with DMs disabled -- Public transparency about what content is not allowed -- Educational for other members - -**Cons:** -- **NOT PRIVATE** - Violation details visible to all users for 10 seconds -- May embarrass users publicly -- Could expose sensitive moderation information -- Privacy-conscious communities may prefer silent failures +**Estimated Costs** (with defaults): +- Small server (< 100 users): ~$5-10/month +- Medium server (100-500 users): ~$15-25/month +- Large server (500+ users): Consider increasing rate limits
