Read the original ↗Part 1 · What the source did
Claude Code, Codex, several Hermes profiles and Grok share one self-hosted memory over MCP; each writes an evening summary and a morning digest spreads the lessons to all.
- Exposes three MCP tools (search, add, stats) over HTTP or stdio.
- Every agent writes a summary of its day each evening.
- A morning digest shares yesterday's lessons with the whole fleet.

Part 2 · Our copy-paste version
Adapted by us from what the source described. Fill in the [BRACKETS].
The prompt
EVENING (each agent): Write 3–5 lessons from today to shared memory. Each: one sentence, the project, and whether it's a rule or an observation. No secrets, no customer data.
MORNING (digest): search yesterday's lessons, deduplicate, and produce a 10-line digest each agent reads at session start.
🛡
Approval ruleReview lessons weekly; delete wrong ones before they spread.
Set it up
- Run a local memory server and register it as an MCP server in each agent.
- Add the evening prompt to each agent's end-of-day routine.
- Schedule the morning digest.
Common failures
⚠
What usually goes wrong
- One wrong lesson propagates to every agent.
- Sensitive data leaking into shared memory.
Variations
- Start with a shared markdown file before an MCP server.
