Exomemory
Give Claude Code structured long-term memory—encoding, storage, selective forgetting, and retrieval—so context survives across sessions.
Overview
exomemory is a plugin marketplace for the build-phase agent-tooling shelf that adds structured long-term memory with encode-store-forget-retrieve stages in Claude Code.
What is this marketplace?
- Cognitive-science framing: encoding, storage, forgetting, and retrieval stages for external memory.
- Productivity-category plugin sourced from hananana/exomemory on GitHub.
- Designed for Claude Code as structured long-term knowledge, not ephemeral chat context.
- Single-plugin marketplace (exomemory) with focused scope versus large workflow bundles.
- Supports disciplined recall instead of dumping entire repos into every prompt.
- 1 plugin in marketplace manifest
- Plugin category: productivity
- Homepage: https://github.com/hananana/exomemory
What problem does it solve?
Agents forget decisions between sessions, forcing solo builders to repeat context and watch quality drift on long-running products.
Who is it for?
Indie builders running multi-week Claude Code projects who need durable, structured agent memory beyond default context windows.
Skip if: Teams that forbid persistent agent memory, or users who only need ephemeral one-shot coding with no cross-session continuity.
What do I get? / Deliverables
After installing exomemory, Claude Code can persist and retrieve structured knowledge so prior decisions resurface without pasting full history each time.
- hananana/exomemory marketplace registered
- exomemory plugin active for structured memory operations
- Repeatable encode/retrieve workflow across coding sessions

Recommended Marketplaces
Journey fit
Memory plugins extend the coding agent first during build, even though payoffs appear when operating and growing the product over weeks. Exomemory is agent-tooling: it changes how the assistant remembers project facts, not how you deploy or market the app.
How it compares
Agent memory plugin marketplace, not a documentation host or vector-database MCP server by itself.
Common Questions / FAQ
Who is Exomemory for?
Claude Code users who want cognitive-science-style external memory for projects that span many sessions and repositories.
When should I use Exomemory?
Use it when repeated context dumping hurts velocity, or when you need forgetting and retrieval discipline—not just unlimited note hoarding.
How do I add Exomemory to my agent?
Register the hananana/Exomemory marketplace in Claude Code, install the Exomemory plugin from ./plugins/Exomemory, and follow the repo README for memory workflows.
