After a few months with Claude Code, beyond Claude Code itself, I’ve gradually accumulated a handful of companion tools and learning resources. They had been scattered across my micro-notes; this post collects them in one place.

Daily Pairing: Claude Extension
My most-used combo: Claude Extension paired with Claude Code. Productivity goes through the roof.
Checking Costs: ccusage
!npx ccusage@latest monthly lets you see detailed API costs. Recommended for anyone using Claude Code.
Finding Old Conversations: claude-log-cli
Conversations from the past 30 days are stored in jsonl. You can install https://github.com/martinalderson/claude-log-cli to quickly find historical conversations. Adjust a parameter to extend the default retention.
Systematic Understanding: how-claude-code-works
Beyond command-line tools, if you want to understand how it works under the hood, this learning resource is well worth reading.
I’ve been scrolling Threads less and reading this site more: https://windy3f3f3f3f.github.io/how-claude-code-works/. Systematic learning beats scattered posts by a mile.
