Agent Shared Memory

A shared knowledge base system for multiple AI Agents, making experience sedimented, reusable, and evolvable.

中文 →

---

What is this?

Agent Shared Memory is a collective learning system designed for multiple AI Agents (Hermes, Kimi-CLI, Claude-Code, Codex-CLI, OpenClaw).

It is not just a note repository, but a complete workflow:

• Check the wiki before acting — avoid repeating mistakes
• Mandatory archiving after tasks — write reusable experience back to the shared vault
• Automated health checks (lint) — monitor knowledge health with the 4-Signal model
• Audit & feedback loop — Agents review each other and improve continuously

Core goal: Make the output of one task reusable in the next 10 tasks.

Core Mechanisms

1. Two-Step Chain-of-Thought Ingest

After reading new material, copy-pasting raw text is forbidden. Agents must execute two steps:

1. Step 1: Analysis — extract entities, concepts, connection points, contradictions
2. Step 2: Generation — only write to the wiki when the Ingest Gate decides Direct Write

2. 4-Signal Health Model

lint.py scans weekly and outputs four health signals:

Signal	Meaning	Ideal
Coverage	Type coverage	No empty dirs
Freshness	Avg page age	< 30 days
Consistency	frontmatter compliance	100%
Connectivity	Orphan page rate	< 10%

3. Graph Insights

lint.py outputs structural insights:

• Surprising Connections: Bridge nodes (cross-domain hubs), Source overlap (related pages not linked)
• Gaps: Agent blindspots, tag islands, undigested sources, stale tasks

When a major Gap is found, Deep Research is triggered by default to close the loop.

4. Audit Lifecycle

graph LR
    A[Create Audit] --> B{Hermes Triage}
    B -->|fix-typo| C[Fix directly]
    B -->|create-page| D[Agent claims]
    B -->|deep-research| E[Start Deep Research]
    B -->|skip| F[Close with reason]
    C --> G[Move to audit/resolved/]
    D --> G
    E --> G
    F --> G

Quick Start

Installation

1. Install Obsidian (optional, for visual browsing)
2. Install the obsidian CLI (required for all Agents to read/write):

   # Confirm installation
   which obsidian && obsidian version
   # Expected: /usr/local/bin/obsidian  1.12.x

3. Clone or locate the vault:

   # Place the vault in a local folder or cloud-synced directory, e.g.:
   $HOME/Library/Mobile Documents/com~apple~CloudDocs/Obsidian/Agent Shared Memory

Configuration

All obsidian commands must specify the vault name:

vault="Agent Shared Memory"

Recommended environment variable:

export AGENT_SHARED_MEMORY_VAULT="$HOME/Library/Mobile Documents/com~apple~CloudDocs/Obsidian/Agent Shared Memory"
python3 "$AGENT_SHARED_MEMORY_VAULT/99-System/lint.py"

Verify access (creates and deletes a test file automatically):

obsidian create name="agent-onboard-test" path="03-Agents/" content="# test" vault="Agent Shared Memory"
obsidian read path="03-Agents/agent-onboard-test.md" vault="Agent Shared Memory"
obsidian delete path="03-Agents/agent-onboard-test.md" vault="Agent Shared Memory"

No CLI? The vault is just a folder of Markdown files. You can read/write directly with Python pathlib or Bash cat/echo if obsidian is unavailable.

Agent Onboarding

Before every task, Agents must read:

obsidian read path="hot.md"
obsidian read path="00-SPEC/PURPOSE.md"
obsidian read path="00-SPEC/AGENTS.md"
obsidian read path="00-SPEC/CONVENTIONS.md"

Common Commands

# Search existing pitfalls
obsidian search query="serde" path="05-Knowledge/Pitfalls/"

# Read your own Agent profile
obsidian read path="03-Agents/Hermes.md"

# Append daily log
obsidian append path="log/20250415.md" content="\n## [14:30] file | Hermes | example-task\n- Done"

# Create an audit
obsidian create name="20250415-143000-typo" path="audit/" content="# typo in AGENTS.md"

Run Health Check

cd "99-System"
python3 lint.py

Design Principles

1. Any Agent should find relevant experience within 30 seconds of starting a new task.
2. The same pitfall should not be stepped on twice by different Agents.
3. Agent profiles should reflect current capability boundaries, not snapshots from 3 months ago.
4. Users can browse directly in Obsidian to understand what each Agent is thinking and learning.
