v2 Setup Wiring — Status & Remaining Work

Last updated: 2026-04-09, branch v2, commit 1dc5750

What's Done

Two-DB Split (session DB write isolation)

• Session DB split into inbound.db (host-owned) and outbound.db (container-owned)
• Each file has exactly one writer — eliminates SQLite write contention across host-container mount
• Host uses even seq numbers, container uses odd (collision-free)
• Container heartbeat via file touch (/workspace/.heartbeat) instead of DB UPDATE
• Scheduling MCP tools emit system actions via messages_out; host applies them to inbound.db in delivery.ts:handleSystemAction()
• Host sweep reads processing_ack table + heartbeat file mtime for stale detection
• Container clears stale processing_ack entries on startup (crash recovery)
• Files: src/db/schema.ts (INBOUND_SCHEMA + OUTBOUND_SCHEMA), src/session-manager.ts, src/delivery.ts, src/host-sweep.ts, container/agent-runner/src/db/connection.ts, messages-in.ts, messages-out.ts, poll-loop.ts, mcp-tools/scheduling.ts, mcp-tools/interactive.ts
• Container image rebuilt with tsconfig excluding v1 (container/agent-runner/tsconfig.json)
• E2E verified: host → Docker container → Claude responds → "E2E works!" ✓

OneCLI Integration

• ensureAgent() call added before applyContainerConfig() in src/container-runner.ts
• Without ensureAgent, OneCLI rejects unknown agent identifiers and returns false, leaving container with no credentials
• E2E verified with OneCLI credential injection ✓

Channel Barrel

• src/index.ts imports ./channels/index.js (the barrel)
• Channel skills uncomment lines in the barrel to enable channels
• Discord is uncommented by default (it was previously a direct import in index.ts)

Setup Registration (partially)

• setup/register.ts rewritten to create v2 entities (agent_groups, messaging_groups, messaging_group_agents) in data/v2.db
• Accepts --platform-id (v2) and --jid (v1 compat) flags
• Added getMessagingGroupAgentByPair() to prevent duplicate wiring
• setup/verify.ts updated to check v2 central DB (counts agent groups with wiring)

Router Logging

• src/router.ts logs MESSAGE DROPPED at WARN level when no agents wired, with actionable guidance

Previously Open — Now Resolved

1. v2 Channel Skills Don't Register Groups ✅

Channel skills now point to /manage-channels in their "Next Steps" section. Registration is handled by the /manage-channels skill, which reads each channel's ## Channel Info section for platform-specific guidance. Channel skills stay lean (credentials only).

2. v1 add-discord Skill is Incompatible ✅

Created /add-discord-v2 skill matching the v2 pattern. Setup SKILL.md updated to reference /add-discord-v2.

3. Setup SKILL.md Missing Group Registration Step ✅

Added step 5a "Wire Channels to Agent Groups" between channel installation (step 5) and mount allowlist (step 6). This step invokes /manage-channels which handles agent group creation, isolation level decisions, and wiring.

4. Channel Skills Should Know Channel Type ✅

Each v2 channel skill now has a ## Channel Info structured section with: type, terminology, how-to-find-id, supports-threads, typical-use, default-isolation. The /manage-channels skill reads this for contextual recommendations.

5. Verify Step Channel Auth Check ✅

setup/verify.ts now checks all v2 channel tokens: DISCORD_BOT_TOKEN, TELEGRAM_BOT_TOKEN, SLACK_BOT_TOKEN+SLACK_APP_TOKEN, GITHUB_TOKEN, LINEAR_API_KEY, GCHAT_CREDENTIALS, TEAMS_APP_ID+TEAMS_APP_PASSWORD, WEBEX_BOT_TOKEN, MATRIX_ACCESS_TOKEN, RESEND_API_KEY, WHATSAPP_ACCESS_TOKEN, IMESSAGE_ENABLED, plus WhatsApp Baileys auth dir.

6. Agent-Shared Session Mode ✅

Added session_mode: 'agent-shared' for cross-channel shared sessions (e.g. GitHub + Slack in one conversation). Session resolution looks up by agent_group_id instead of messaging_group_id when this mode is set.

Architecture Reference

v2 Entity Model

agent_groups (id, name, folder, agent_provider, container_config)
    ↕ many-to-many
messaging_groups (id, channel_type, platform_id, name, is_group, unknown_sender_policy)
    via
messaging_group_agents (messaging_group_id, agent_group_id, trigger_rules, session_mode, priority)

users (id, kind, display_name)          -- namespaced as "<channel>:<handle>"
user_roles (user_id, role, agent_group_id)    -- owner / admin (global or scoped)
agent_group_members (user_id, agent_group_id) -- unprivileged access gate
user_dms (user_id, channel_type, messaging_group_id)  -- cold-DM cache

Privilege is a user-level concept — there is no "main" agent group or "admin" messaging group. user_roles carries owner (global only, first pairing sets it) and admin (global or scoped to an agent_group_id). Unknown-sender gating is per-messaging-group via messaging_groups.unknown_sender_policy (strict | request_approval | public).

Message Flow

Channel adapter → routeInbound() → resolve messaging_group → resolve agent via messaging_group_agents
→ resolve/create session → write to inbound.db → wake container → agent-runner polls inbound.db
→ agent responds → writes to outbound.db → host delivery poll reads outbound.db → deliver via adapter
