Claude Code memory

How to give Claude Code persistent memory

Claude Code is strongest when it has the right project context. Persistent memory makes that context survive new sessions, branch switches, and the “wait, we already fixed this” moments.

Short answer: give Claude Code persistent memory by installing a local memory layer that recalls project context before each task and observes durable facts after each session. Remnic does this with Claude Code hooks plus MCP.

What Claude Code needs to remember

The useful memories are usually practical: repo conventions, prior decisions, local setup quirks, commands that worked, commands that failed, and preferences you do not want to repeat.

Generic chat memory is not enough because coding work is scoped. A fact that matters in one repo can be irrelevant or dangerous in another.

Why hooks matter

If memory is only a tool, the model has to remember to use the tool. Hooks make recall part of the session structure. Before Claude Code answers, Remnic can retrieve relevant memories and inject them into the context automatically.

Why local storage matters

Coding memory often includes private filenames, internal decisions, deployment details, and debugging trails. A local-first memory layer keeps that material on your machine as inspectable files instead of sending it to a hosted memory API.

Install path

With Remnic, the short path is the CLI install followed by the Claude Code connector. From there, Remnic can recall through MCP, observe through hooks, and keep the memory store shared with Codex CLI, Cursor, and other agents.

See the Claude Code integration page for the exact setup.
