How I Cut Claude Code Costs by 53% with a 7-Layer Stack

I've been running Claude Code heavily for months. After the first billing cycle I realized I was burning through API credits faster than I expected. Most of it was going to Opus when Sonnet would have done the job fine, and a lot of it was raw terminal output flooding Claude's context window with noise it didn't need.

So I built a stack. Seven layers, each attacking waste from a different angle. Together they dropped my daily spend from about $27 to $13, a 53% reduction, while making Claude more capable in practice, not less.

Here's the full setup.

function attach_session() {
    local session_root=$1
    local session_name=$(basename "$session_root" | tr . _)
    cd $session_root
    zellij attach --create $session_name

Flask-SQLAlchemy Caching

The following gist is an extract of the article Flask-SQLAlchemy Caching. It allows automated simple cache query and invalidation of cache relations through event among other features.

Usage

retrieve one object

# pulling one User object

user = User.query.get(1)
