Know What It Costs and Keep Long Sessions on Track, Complete Resource Pack

Arun Nagarathanam · 31 Aug 2026 · Guide · 45 of 59 in this course

An exclusive resource for students of Arun's Claude Code Course.

When this section started you could not have said what your own tool was spending, or been sure that something you approved could be taken back. You were driving, but you could not see the dashboard. Here is what you walk out holding.

The five things you keep

Your Command Cheat Sheet
From earlier in the course, with your own four readings written into it.

Your Claude Code Permissions File, and What Every Line Does
Tuned the way you like it, with the line you added yourself so it stops Claude changing your keys file and not only reading it.

Cost Rules Starter
The two habits you ticked, chosen against your real numbers rather than the ones that sound most disciplined.

Session Handoff Template and Session Contract Template
The pair you use to start clean. One ends a session on purpose, the other opens one with the mission and the boundaries already named.

My Claude Code Workflow Preferences
The record of a setup you chose on purpose, with one sentence of reasoning next to every choice. That reasoning is the whole point. Anyone can copy a setup. You are building one you understand, which means you can change it when your work changes.

Also on the shelf

Official Documentation: Costs, Usage and Models
For the days you want to check a number rather than trust one you read somewhere.

Risk Assessment Before A Rework
The question to run at two different effort levels, so you see the gap for yourself instead of being told about it.

The habit underneath all of it

Keep one mission per session. Watch how full the conversation is getting. Hand off before the work drifts rather than after. And never take Claude's word for the state of the world, because a model that is drifting reports success just as confidently as one that is right. You check from outside. You look at the real saved history, you run the thing, you let the test or the compiler be the judge.


See Where You Stand

This resource is one piece of a much bigger system.

Take the free Claude Code Readiness Quiz. It is 15 short situations, scored out of 100, and it tests how you handle a job rather than what you know about a tool, so you can take it without ever having opened Claude Code.
