Claude Code practical guides
Five guides and one deep dive, ordered by the problem you actually hit, not by difficulty. Each opens with a one-sentence conclusion, then steps, then a trade-off table — reading only the conclusion is legitimate.
If you fix one thing, fix environment consistency: system timezone, preferred language, region format, browser fingerprint. It is the only layer entirely under your control and verifiable afterwards. Its limit: it does not exempt you from the first clause of the official terms, which is about being physically located in an unsupported region. Within what the terms allow, it stops you adding suspicious signals. The checklist takes about ten minutes.
Setup, environment and traces
Get the foundation right first. These three answer "does this machine look like a real machine" and "where does it give itself away".
Environment consistency checklist
Five signals one at a time — timezone, language, region format, browser fingerprint: where each is read, the correct value, how to verify the change.
About 6 minutes · concrete setting paths Start here · scenarioTravelling without losing the account
For a legitimate account that crosses borders: one checklist before departure, one during the trip. Timezone follows you, payment stays stable, accounts stay unshared.
About 8 minutes · two checklists Technical · deep diveHow your traces leak
IP and ASN, DNS leaks, WebRTC candidates, browser and device fingerprints, TLS fingerprints, behaviour — layer by layer, with a self-test for each.
About 14 minutes · self-test checklistChoosing and migrating
With the foundation right, the question is whether to change the structure at all. Price the cost before deciding.
What only Claude Code does
The agent loop, CLAUDE.md, subagents, hooks and MCP described plainly, and which of them you lose by switching.
About 8 minutes · read before migrating Choosing · smallest changeGateways and third-party models
Three supplier types ranked by risk, where compatibility degrades, and six checks that decide whether a gateway is worth trusting.
About 8 minutes · verification checklist Migration · most thoroughMigrating to an open-source harness
A concept mapping table, a seven-step migration, a dual-run transition, and the capabilities that are definitely lost.
About 8 minutes · mapping tableHow to read these
Foundation before architecture: fixing the environment costs minutes, migrating a workflow costs weeks. Start where your problem is; nothing here has to be read in order.
The other line: the account is already gone
These guides are about using the tool well. Why an account went away, how it was detected and what can still be recovered is a separate set of pages; reading them together muddles both.
Common questions
What should I fix first?
Environment consistency: system timezone, preferred language, region format and browser fingerprint. It is the only layer fully under your control and measurable afterwards, and the checklist takes about ten minutes.
Does a consistent environment put me outside the region rule?
No. It does not exempt you from the first clause of the official terms: being physically located in an unsupported region still applies, however consistent the machine is. What it does is avoid adding suspicious signals within what the terms allow.
Should I migrate to another harness?
Price the cost first. The agent loop, CLAUDE.md, subagents, hooks and MCP each degrade differently, and the seven-step migration only makes sense to judge after that.
Do these guides cover a banned account?
No. They cover using the tool well. Why an account went away, how it was detected and what can still be recovered sit in the ban cluster, which is read separately.
