Claude Code Memory: Persistent Project Context Across Sessions

Claude Code is strongest when it understands the project: architecture, conventions, pitfalls, release process, and the reasoning behind prior decisions. But sessions end, context windows fill, and important discoveries get lost.

Persistent memory closes that gap. It lets the coding agent recover what has already been learned instead of asking you to repeat background every time.

CLAUDE.md is excellent for stable, project-level instructions: build commands, architecture notes, style rules, and long-lived conventions. It should not become a dumping ground for every transient observation from every coding session.

Origin is designed for the evolving layer: facts, decisions, gotchas, follow-ups, and relationships learned while working. The two are complementary.

Useful coding memory is specific and grounded. It should capture why a decision was made, what tradeoffs were considered, what commands verify a change, and which files or modules own a behavior.

It should not merely store chat transcripts. The point is to make future sessions faster and less error-prone.

Origin exposes memory through MCP via origin-mcp. Claude Code can write what it learns and recall relevant project context later. The same memory can also be available to Cursor, Claude Desktop, ChatGPT, and Gemini CLI when configured.

That makes Origin a shared memory layer for AI-assisted development rather than a single-client note file.

Start with your project instructions in CLAUDE.md. Add Origin as an MCP server. Let Claude Code store durable findings as work happens: preferences, architecture decisions, debugging lessons, and follow-up tasks.

When a later session starts, the assistant can retrieve the relevant memory instead of starting from zero.
