Opt-in Add-on

commonmemory

Shared cross-agent memory convention and notebook built on the agentmemory signal bus.

Problem Solved

In standard multi-agent workflows, each agent maintains its own ephemeral context window. When Claude discovers a subtle dependency bug or project convention, that insight is lost when a subagent exits, and remains invisible to the Antigravity peer unless manually repeated in prompts.

commonmemory establishes a standardized tagging convention and persistent memory notebook that both Claude Code and Antigravity can write to and query dynamically.

Main Capabilities

Structured Fact Tagging: Categorizes project learnings under standard tags (decisions, gotchas, bugfix, architecture).
Cross-Session Persistence: Keeps critical repository knowledge available across separate terminal invocations.
Proactive Context Injection: Teaches agents when to consult the shared memory store before planning new features.
Zero Cloud Relays: Operates locally via the lightweight @agentmemory/agentmemory package.

Installation & Setup

1. Ensure the @agentmemory/agentmemory dependency is installed:

npm install -g @agentmemory/agentmemory

2. Install the Clavity plugin:

claude plugin install commonmemory@clavity

Requirements & Prerequisites

Requirement	Specification
Runtime Dependency	Node.js / npm (for `@agentmemory/agentmemory`)
Host Plugin	Clavity Bridge (`clavity-dotnet` or `clavity-classic`)
Supported Agents	Claude Code and Google Antigravity

Known Limitations

Requires Node.js runtime on PATH to support the agentmemory CLI bus.
Memory entries are scoped to the active workspace repository.
