+## [1.3.0] - 2026-10-27
+
+### Changed
+
+- Repositioned from "an egress gate" to a one-stop Claude Code deployment and
+  operation skill. The binary gate stays the enforcement core; the skill now names
+  four parts explicitly — deploy, egress, operate, respond — in `SKILL.md`, both
+  READMEs, `AGENTS.md` and `llms.txt`.
+
+### Added
+
+- `references/safe-operation.md`: credential handling, client settings (no proxy
+  in `settings.json`, keep permission prompts, review hooks and MCP servers,
+  one installation), secrets in the working tree, working-directory blast radius,
+  monitoring, incident response for exit changes / verification requests / leaked
+  credentials / suspected bypass, and update discipline.

+**一站式 skill + 一键安装：在 Linux 上安全地部署和运行 Claude Code——从裸机到可用、
+可审计的客户端，以及出问题时知道怎么处置。**
+
 在 VPS 上跑 Claude Code，最容易出问题的不是安装，而是**出口泄漏**：写在
 `/etc/profile.d` 里的 `claude()` 函数只覆盖交互式 shell，Python、`sh -c`、
 cron、systemd 和任何直接调用 `/usr/bin/claude` 的路径都会绕过去；代理中途挂掉时，
 客户端还会悄悄从机房 IP 直连出去。
 
-这个项目在**二进制层**补上这个洞：`claude` 命令本身变成闸门，启动前核验代理的真实
-出口地址，注入代理变量，并可选地把整个进程树关进内核级 IP 白名单。任何异常都拒绝
-启动，没有「继续执行」的分支。
+所以项目分成四块，只有一个是强制核心：
+
+| 部分 | 覆盖什么 | 入口 |
+| --- | --- | --- |
+| **部署** | 资格判断、主机基线、代理先稳定、装客户端但不启动、首次登录走闸门 | `preflight`、[`zero-to-deployed.md`](skills/claude-egress-guard/references/zero-to-deployed.md) |
+| **出口** | 固定出口、注入代理、内核白名单、更新自愈、失败不回落 | `install`、`verify --deep`、`drill`、`set-exit` |
+| **运行** | 凭据、客户端设置、密钥卫生、影响范围、备份、监控 | [`safe-operation.md`](skills/claude-egress-guard/references/safe-operation.md) |
+| **处置** | 出口变化、被要求验证、凭据泄漏、怀疑绕过 | [`safe-operation.md`](skills/claude-egress-guard/references/safe-operation.md) §6 |
+
+强制核心仍然是二进制闸门：`claude` 命令本身核验代理的真实出口地址、注入代理变量，
+可选地把整个进程树关进内核级 IP 白名单。任何异常都拒绝启动，没有回落。另外三块存在
+的意义，是让这道闸门**按正确顺序装上**，并且在第一周之后仍然有意义。

-# Claude Egress Guard
+# Claude Code: safe deployment and operation
 
-Install a fail-closed egress gate in front of Claude Code on a Linux host: every
-invocation must pass an exit-address check, the client and its children get proxy
-variables, and (by default) the whole process tree is jailed with a kernel-level
-IP allow list. Anything unexpected refuses to start instead of falling back.
+A one-stop skill for running Claude Code on a Linux host you control: bring a bare
+machine to a working, gated client, keep it inside one verified egress, and know
+what to do when something goes wrong.
+
+Four parts, in the order they matter:
+
+| Part | What it covers | Where |
+| --- | --- | --- |
+| **Deploy** | eligibility, host baseline, proxy proven stable, client installed but not launched, first login through the gate | `references/zero-to-deployed.md`, `preflight` |
+| **Egress** | one verified exit, proxy injection, kernel jail for the whole process tree, self-heal after updates, no fallback | `install` / `verify --deep` / `drill` / `set-exit` |
+| **Operate** | credentials, client settings, secrets, working-directory blast radius, backups, monitoring | `references/safe-operation.md` §1-5 |
+| **Respond** | exit change, verification request, leaked credential, suspected bypass | `references/safe-operation.md` §6 |
+
+The enforcement core is still one binary: `claude` becomes a gate that refuses to
+start when the exit is not the one you configured. The rest of the skill exists so
+that the gate is installed in the right order, and stays meaningful afterwards.

+# Safe operation baseline
+
+The gate decides where traffic leaves. This file decides everything else that
+makes a Claude Code deployment safe to keep running: credentials, client
+settings, secrets, backups, monitoring and what to do when something looks wrong.
+
+It applies after `references/zero-to-deployed.md` has taken you to a working,
+gated host.
+
+## 1. Credentials
+
+- `~/.claude/.credentials.json` is a **session**, not a config file. Mode 600,
+  owned by the account that runs Claude. Never copy it to another machine, never
+  put it in a backup that leaves the host.
+- Re-login is the rotation mechanism. If the file may have leaked: `claude auth
+  logout`, sign out the other sessions from the provider's account page, log in
+  again, then check usage for anything you do not recognise.
+- Login codes are single use and short lived. Do not paste them into a chat, a
+  ticket, a log or a shell history. If an orchestrator passes one through stdin,
+  it must not echo it.
+- Never store a provider token in `CLAUDE.md`, `settings.json`, a git remote URL
+  or a shell profile.
+
+## 2. Client settings
+
+The gate owns egress. The client must not have a second opinion:
+
+- **No proxy in `~/.claude/settings.json`.** A value there can win over the
+  environment the gate exports, which is the quietest way to send traffic around
+  the gate.
+- **Keep permission prompts on** unless the directory is a throwaway sandbox.
+  A blanket "allow everything" setting turns every prompt injection into a shell.
+- **Review hooks and MCP servers before enabling them.** Both execute code with
+  your privileges; a hook added for convenience is a startup script with your
+  keys in scope.
+- **One installation.** `npx`, a second global install, or a wrapper that calls
+  the real binary are ungated paths. Remove them or accept that the gate does not
+  cover them.
+
+## 3. Secrets in the working tree
+
+- Keep API keys in a `.env` with mode 600, or in a secret manager. Not in
+  `CLAUDE.md`, not in committed examples, not in prompts.
+- Add `.env`, `*.pem`, `*.key` and `credentials*` to `.gitignore` before the first
+  commit, not after the first leak.
+- `~/.claude/` and the project's `.claude/` should not be world-readable:
+  `chmod 700 ~/.claude`, `chmod -R go-rwx .claude` where it exists.
+- When you paste logs into an issue, strip addresses, tokens, account identifiers
+  and full config files. Documentation ranges (`203.0.113.0/24`) exist for this.
+
+## 4. Working directory and blast radius
+
+- Run Claude in a dedicated directory, not `/` and not your home root. A
+  mistaken `rm` or a wide refactor should hit a project, not a system.
+- Keep the project under git. Review diffs before accepting bulk edits; a clean
+  `git diff` is the cheapest safety net there is.
+- Do not run unattended, long-lived agents against production credentials. If you
+  must, give them a scoped token and a directory they cannot escape.
+- Snapshot before large changes (`git stash`, a tarball, a provider snapshot).
+
+## 5. Monitoring
+
+- `LOG_REFUSALS=1` turns "did it ever refuse?" into `journalctl -t
+  claude-egress-guard`. Check it weekly; a burst of refusals means the proxy is
+  unstable, not that the gate is broken.
+- After every package update: `claude-egress-guard verify --deep`. The self-heal
+  is best effort, verification is proof.
+- Keep a one-line change log for policy edits (who changed `EXPECTED_IP`,
+  `ALLOW_IPS` or `STRICT_NET`, and why). Six months later this is the only thing
+  that explains an incident.
+- Record the version you are on. `claude --version`, `claude-egress-guard status`.
+
+## 6. Incident response
+
+Match the symptom, then act in order. Stop the bleeding before you investigate.
+
+### Exit changed or a leak is suspected
+
+1. Stop new sessions; let running ones finish or kill them deliberately.
+2. Confirm the current exit: `claude-egress-guard status`, then a trace through
+   the proxy.
+3. If the proxy moved, `set-exit --ip NEW --country CC`; if it is dead, leave the
+   gate refusing. A refusing gate is working correctly.
+4. Read `journalctl -t claude-egress-guard` for when refusals started.
+5. Only then review IP history and decide whether the provider needs to hear
+   from you.
+
+### The provider asks for verification, or the session is signed out
+
+1. Do not retry from a different address. Address hopping during a review is the
+   worst possible signal.
+2. Stop automation that would keep opening sessions.
+3. Follow the provider's instructions truthfully, or stop and reassess
+   eligibility. Never supply documents or numbers that are not yours.
+4. Preserve logs and the deployment record; do not delete evidence.
+
+### A credential may have leaked
+
+1. `claude auth logout` on the host.
+2. Revoke sessions from the provider's account page.
+3. Re-login through the gate, then `verify --deep`.
+4. Check usage and recent activity for anything you cannot explain.
+5. Fix the path it leaked through (git history, a pasted log, a world-readable
+   file) before moving on.
+
+### A bypass is suspected
+
+1. `claude-egress-guard status` — is the gate still installed at both paths?
+2. `npx`, a second install, a wrapper, a container: list every way `claude` can
+   start on that host.
+3. For a running process, `cat /proc/<pid>/cgroup` should show a `run-r...scope`
+   when `STRICT_NET=1`. If it does not, that process did not come through the
+   gate.
+4. Fix the entry point, then drill again.
+
+## 7. Update discipline
+
+| Change | Follow-up |
+| --- | --- |
+| Claude Code update | `verify --deep`, one real prompt |
+| OS upgrade | re-check systemd version, IPv6 setting, DNS resolvers, then `verify --deep` |
+| Proxy change | `set-exit`, then `verify` |
+| Policy change | record it, then `verify --deep` |
+| Host rebuild | follow `zero-to-deployed.md` from phase 1; do not copy credentials |
+
+## 8. What stays out of scope
+
+Account registration, payment, identity verification, and anything that would
+misrepresent who you are or where you are. Those are the operator's, permanently.
