Components Status

Component Status Notes
Discord Bot ✅ Online Connected to Discord
Database ✅ Connected SQLite with migrations
Prompt Resolver ✅ Initialized Custom prompts ready
Guild Config Store ✅ Available CRUD operations ready
Prompt Commands ✅ Registered 5 subcommands available
Summarization Engine ✅ Integrated Using prompt resolver
Encryption ✅ Active Fernet for tokens

Discord Commands

New Commands Added:

  • /prompt-config set <repo_url> [branch] ✅
  • /prompt-config status ✅
  • /prompt-config remove ✅
  • /prompt-config refresh ✅
  • /prompt-config test <category> ✅

Existing Commands:

  • /summarize ✅ (now uses custom prompts if configured)
  • /schedule ✅
  • /help ✅ (updated with prompt-config)
  • /status ✅
  • /ping ✅
  • /about ✅

Integration Verification

Expected Behavior

  1. Default Mode (No Configuration)

    • Bot uses built-in default prompts
    • Summarization works as before
    • No breaking changes

  2. After Configuration

    • Admin uses /prompt-config set github.com/repo/path
    • System validates repository and PATH file
    • Future summaries use custom prompts from GitHub
    • Fallback to defaults if GitHub unavailable

  3. Command Visibility

    • All users can see /prompt-config status and test
    • Only admins can use set, remove, refresh

Testing Commands

Test 1: Check Status (No Config)

/prompt-config status
Expected: "This server is using the default built-in prompts"

Test 2: Default Summarization

/summarize
Expected: Works normally with default prompts

Test 3: Test Command

/prompt-config test discussion
Expected: Shows default prompt for discussion category

Database Schema

Migration 003_guild_prompt_configs.sql already applied in Phase 2.

Tables:

  • ✅ guild_prompt_configs - Guild configurations
  • ✅ prompt_cache - Cached prompts
  • ✅ prompt_fetch_log - Fetch logging for observability

Security Configuration

Environment Variables

Required:

  • ✅ OPENROUTER_API_KEY - LLM API access
  • ✅ DISCORD_TOKEN - Bot token

Optional (Phase 3):

  • ⚠️ PROMPT_TOKEN_ENCRYPTION_KEY - Not set (using ephemeral key)

Note: Without PROMPT_TOKEN_ENCRYPTION_KEY, GitHub tokens are encrypted but won't persist across restarts. For production with private repositories, set this environment variable.

Generate Encryption Key

from cryptography.fernet import Fernet
key = Fernet.generate_key()
print(key.decode())

Then set in Fly.io:

flyctl secrets set PROMPT_TOKEN_ENCRYPTION_KEY="<generated-key>" -a summarybot-ng

Features Now Available

For Guild Administrators

  1. Configure Custom Prompts

    • Point to any public GitHub repository
    • Specify branch (defaults to main)
    • Automatic validation before saving

  2. Monitor Status

    • Check current configuration
    • View last sync time and status
    • See cache statistics
    • Review validation errors

  3. Manage Configuration

    • Refresh cache for updated prompts
    • Remove configuration to revert to defaults
    • Test prompt resolution before using

For All Users

  1. View Configuration

    • Check if custom prompts are configured
    • See repository URL and sync status

  2. Test Prompts

    • Preview prompts for different categories
    • Verify variable substitution

For Developers

  1. External Prompt Repository
    • Create GitHub repository with prompts
    • Define PATH file for routing
    • Use template variables: {category}, {channel}, {type}
    • Version control prompt changes

Rollback Plan

If issues arise, rollback to previous version:

flyctl deploy --app summarybot-ng --image summarybot-ng:deployment-01KF16Z3B98R0C5S8SXQD8FK6S

This reverts to v23 (Phase 2 - foundation only, dormant).

Alternatively, rollback to v22 (before external prompts):

flyctl deploy --app summarybot-ng --image summarybot-ng:deployment-01KEZ0A1ZG1PTREZA2FX1EMM2J

Known Issues & Limitations

Current Limitations

  1. Ephemeral Encryption

    • Without PROMPT_TOKEN_ENCRYPTION_KEY, tokens don't persist across restarts
    • Development: Acceptable
    • Production with private repos: Must set environment variable

  2. Public Repositories Only (Current)

    • Private repository support exists in code
    • Requires admin to provide GitHub Personal Access Token
    • Token encrypted with Fernet before storage

  3. No Automatic Sync

    • Changes to GitHub repository require manual cache refresh
    • Future: Implement webhook notifications for automatic updates

No Breaking Changes

✅ All existing functionality preserved:

  • Default summaries work without configuration
  • Existing commands unchanged
  • No database schema conflicts
  • Graceful fallback on errors

Monitoring

Logs to Watch

# Watch for prompt resolver initialization
flyctl logs -a summarybot-ng | grep -i prompt

# Watch for errors
flyctl logs -a summarybot-ng | grep -i error

# Watch for command usage
flyctl logs -a summarybot-ng | grep "prompt-config"

Metrics to Track (Future)

  • Prompt resolution time
  • Cache hit rate
  • GitHub fetch success rate
  • Fallback chain usage
  • Command usage statistics

Next Steps

Immediate Testing

  1. Verify Commands Appear

    • Check Discord for /prompt-config commands
    • Verify all 5 subcommands visible

  2. Test Default Behavior

    • Use /prompt-config status (should show no config)
    • Use /summarize (should work with defaults)

  3. Test Command Functionality

    • Try /prompt-config test discussion
    • Verify proper error messages for invalid repos

Optional Enhancements (Phase 4)

  1. Production Encryption

    • Set PROMPT_TOKEN_ENCRYPTION_KEY environment variable
    • Enable persistent token storage

  2. Test Repository

    • Create test GitHub repository
    • Add PATH file and prompts
    • Configure test guild
    • Verify full workflow

  3. Monitoring & Metrics

    • Add Prometheus metrics
    • Implement health dashboard
    • Track usage statistics

  4. Advanced Features

    • Webhook notifications for prompt updates
    • Prompt versioning and rollback
    • A/B testing different prompts
    • Analytics dashboard
