DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

 * Set a shared environment as the organization's [default environment](#the-default-environment) at [claude.ai/admin-settings/claude-code](https://claude.ai/admin-settings/claude-code).
 * [Pin one to a channel](https://claude.com/docs/claude-tag/admins/troubleshooting#channel-sessions-use-the-wrong-environment-or-can%E2%80%99t-find-one) in the Claude Tag admin settings.
 
-Shared environments add to members' selectors rather than replacing them.

 ## Network access
 
 Each environment sets one network access level, which controls the outbound connections its sessions can make. The default level, **Trusted**, allows package registries and other [allowlisted domains](#default-allowed-domains); **Custom** takes your own domain list.
from line 393
 * **Requires network access**: install commands need to reach package registries. If your environment uses **None** network access, these hooks fail. The [default allowlist](#default-allowed-domains) under **Trusted** covers npm, PyPI, RubyGems, and crates.io.
 * **Proxy compatibility**: in Anthropic-hosted environments, all outbound traffic passes through a [security proxy](#security-proxy), and some package managers don't work correctly with it; Bun is a known example. In a [self-hosted environment](/docs/en/self-hosted-environments-deploy#default-deny-egress), outbound traffic goes through your own network boundary instead.
 * **Adds startup latency**: hooks run each time a session starts or resumes, unlike setup scripts which benefit from [environment caching](#environment-caching). Keep install scripts fast by checking whether dependencies are already present before reinstalling.

-To persist environment variables for subsequent Bash commands, write to the file at `$CLAUDE_ENV_FILE`. See [SessionStart hooks](/docs/en/hooks#sessionstart) for details.
 
 To customize the base image, use a setup script to install what you need on top of the [provided image](#installed-tools), or run your own image as a container alongside Claude with `docker compose`. Replacing the base image entirely isn't supported yet.
