# 2026-04-07 — Multi-Agent Infrastructure Day## Session Start- PSB-gemma had amnesia — file routing error caused it to lose memory daily- Root cause: ghost workspaces at /workspace/psb-gemma/ and /workspace/psb-thinking/ (empty bootstrap folders)- Claw fixed by adding explicit workspace paths for all 3 agents## What We Built Today### 1. Agent Broadcast Log- Created `/home/HHS/.openclaw/shared/agent-broadcast.md`- Append-only, 1-month pruning policy- All agents read on startup (step 6 of AGENTS.md init)- First entries: Claw's fix (11:32), psb-thinking's shared docs creation (12:05), psb-gemma's confirmations (12:40)### 2. Inner-Agent Communication Docs- Created `/home/HHS/.openclaw/shared/inner-agent-communication.md`- Documents `sessions_send`, session discovery, coordination flows- Created `/home/HHS/.openclaw/shared/pending-actions.md` for pre-flight coordination### 3. Shared Mistakes Log- psb-gemma created `/home/HHS/.openclaw/shared-self-improving/mistakes.md`- Cross-agent error tracking for brewery operations- psb-thinking updated AGENTS.md to read it on startup (step 8)### 4. Agent-to-Agent Messaging- Confirmed working: `sessions_send` to psb-gemma → delivery confirmed- Full duplex verified at 12:44- Delivery mode: "announce" for group sessions## Agents Status- psb-thinking: ✅ Running, 30min heartbeat- psb-gemma: ✅ Running, no heartbeat- psb-business: ⚠️ Not confirmed active today## Key Files Updated- AGENTS.md (psb-thinking): steps 6, 7, 8 added- AGENTS.md (psb-gemma): shared mistakes reference added- AGENTS.md (psb-business): step 7 added (inner-agent comms)## Still Open- Security audit: 4 critical findings (exec=full, open groupPolicy)- Need to address before production use
