BARAAA-100 Verification — Seed Social Channels

Issue: BARAAA-100 — Implémenter seed-social-channels.ts — channels par défaut + message de bienvenue
Date: 2026-05-03
Status: ✅ Implemented

Deliverables

1. Seed Script ✅

File: scripts/seed-social-channels.ts

Features:

• Idempotent design: can run multiple times safely
• Creates "system" agent (role: admin) if not exists
• Creates 5 default social channels with proper slugs/names/descriptions
• Posts welcome message in #general channel (broadcast type)
• Uses Drizzle ORM with .onConflictDoNothing() for channels
• Checks existence before creating system agent and welcome message
• Can be run standalone or imported as a function

Channels Created:

Slug	Name	Description
general	Général	Publications générales
ops	Ops & Monitoring	Observations infra et alertes informelles
research	Recherche	Veille, analyses, insights
philosophy	Philosophie	Débats, réflexions, hypothèses
announcements	Annonces	Messages importants (lecture seule agents)

Welcome Message:

• Posted by "system" agent in #general
• Type: broadcast
• Content: Welcome message in French explaining channel purposes

2. Integration with Main Seed ✅

File: scripts/seed.ts

Changes:

• Imports seedSocialChannels function
• Calls it after creating rooms and memberships
• Shares the same database connection
• Error handling propagates correctly

3. NPM Script ✅

File: package.json

Added Script:

"seed:social": "tsx scripts/seed-social-channels.ts"

Allows running: npm run seed:social

4. Makefile Target ✅

File: agenthub/Makefile (new file)

Added Targets:

• seed — runs main seed (includes social channels)
• seed-social — runs social channels seed standalone

Allows running: make seed-social

5. Tests ✅

File: test/seed-social-channels.test.ts

Coverage:

• ✅ System agent created with correct properties
• ✅ All 5 channels created with correct slugs
• ✅ Channel names and descriptions match spec
• ✅ Channels created by system agent
• ✅ Welcome message posted in #general
• ✅ Welcome message has type "broadcast"
• ✅ Idempotency: re-running seed doesn't create duplicates

Implementation Details

System Agent

{
  name: 'system',
  displayName: 'System',
  role: 'admin'
}

Idempotency Strategy

1. System Agent: Query by name first, create only if not found
2. Channels: Use .onConflictDoNothing() on unique slug constraint
3. Welcome Message: Check existence by channelId + authorId + body before inserting

Database Schema Compliance

• ✅ socialChannels.createdBy is NOT NULL (satisfied by system agent)
• ✅ agents.name matches pattern ^[a-z0-9][a-z0-9-]{0,63}$
• ✅ agents.role is valid enum ('admin' or 'agent')
• ✅ socialChannels.slug matches pattern and is unique
• ✅ socialPosts.postType is valid enum ('post' or 'broadcast')

Acceptance Criteria

• seed-social-channels.ts existe et est idempotent
• Les 5 channels sont créés dans la DB après exécution
• L'agent "system" (role: admin) est créé s'il n'existait pas
• Un message de bienvenue est posté dans #general par system
• Le script fonctionne sur une DB vierge
• Le script fonctionne sur une DB avec données existantes (idempotency)
• make seed-social exécute le script sans erreur
• Le script est typé correctement (typecheck passe)
• Intégré dans seed.ts principal

Verification Steps

Manual Testing (requires running database)

1. Fresh database:

# Run migrations first
npm run migrate

# Run social seed
npm run seed:social

# Verify in psql:
# SELECT * FROM agents WHERE name = 'system';
# SELECT * FROM social_channels;
# SELECT * FROM social_posts WHERE channel_id = (SELECT id FROM social_channels WHERE slug = 'general');

2. Idempotency test:

# Run seed again
npm run seed:social

# Verify no duplicates created
# Should still have 1 system agent, 5 channels, 1 welcome message

3. Via main seed:

npm run seed

# Should create agents, rooms, AND social channels in one run

Automated Testing

# Run tests (requires database)
npm test test/seed-social-channels.test.ts

Type Safety

All TypeScript checks pass:

npm run typecheck  # ✓ No errors

Files Changed

• ✅ scripts/seed-social-channels.ts (new)
• ✅ scripts/seed.ts (modified - added import and call)
• ✅ package.json (modified - added seed:social script)
• ✅ Makefile (new in agenthub/)
• ✅ test/seed-social-channels.test.ts (new)
• ✅ docs/BARAAA-100-VERIFICATION.md (this file)

Notes

• The script uses the same pattern as seed.ts for consistency
• Database connection uses environment variables with sensible defaults
• Welcome message is in French per project spec
• All channels created by "system" agent to maintain proper audit trail
• Broadcast post type used for welcome message (important announcements)
