Session Context Preservation

Prompt:

 when using claude code sessions, how do i preserve the context across sessions, even if they run at the same time

When using Claude Code, you can preserve and share context across sessions using a few methods:

CLAUDE.md files

The primary way to persist context is through CLAUDE.md files. Claude Code automatically reads these at the start of each session:

Project-level: Create a CLAUDE.md in your project root for project-specific context, conventions, and instructions
User-level: Create ~/.claude/CLAUDE.md for personal preferences that apply across all projects

Session memory with --resume and --continue

 claude --continue or -c: Resumes your most recent conversation
 claude --resume: Opens a session picker to choose from past conversations
 claude --resume "session-id": Resumes a specific session by ID

For parallel sessions sharing context

If you need multiple simultaneous sessions to share state:

Use a shared CLAUDE.md file that all sessions read
Write intermediate results or shared state to files in your project that other sessions can read
Use claude --print mode for non-interactive sessions that can output to files other sessions consume

Session checkpoints

You can create a checkpoint of your current session's context by asking Claude Code to summarize the current state, and write it to CLAUDE.md or another file.

For the most current and detailed information, check [docs.claude.com the Claude Code documentation], as features may have been added since my knowledge cutoff.

Installation

Install via bash script from here:

curl -fsSL https://claude.ai/install.sh | bash

Plan

WHATEVER YOU CHOOSE, immmediately turn this off, or it will suck up and train on your code:

Settings > Privacy >

There's more crazy privacy stuff to watch out for here.

Billing

I started with the API usage billing.
It's expensive. I chewed up $5 pretty fast, so I added $25 more.
It chewed up $14 of the $30 building sceneKitScrap. Not terrible value, not great either.
I switched to the Pro plan for $20/month.
TBD if that will be useful or so limited it is a total waste of time. Max 5x plan is $100/mo. Fucking profiteers.
