## Upgrade

```bash
image-use update
image-use upgrade # install the latest release and refresh the skill
image-use upgrade --check # only report: image-use 0.29.2 -> 0.30.0
image-use upgrade --json # the same as JSON
```

It runs the `skills` manager for you — directly when `skills` is on PATH, through `npx` when it isn't (it usually isn't). Interactive runs check for a newer version at most once a day and upgrade automatically for the next run; failures fall back to a notice listing what changed. `IMAGE_USE_NO_AUTO_UPDATE=1` disables installation but keeps the check and notice, while `IMAGE_USE_NO_UPDATE_CHECK=1` disables both. `--quiet`/`--no-progress` never upgrades in the background.
`upgrade` (alias `update`) installs the newest GitHub release the same way this copy was installed — `skills update` for an `npx skills add` install, `git pull --ff-only` for a clone, a fresh copy of the script for a standalone file — then refreshes every other copy of the skill it finds (Claude Code plugin, clones and copies under `~/.agents/skills`, `~/.claude/skills`, `~/.codex/skills`). Any other command checks for a newer release at most once a day and prints one line to stderr when there is one. `IMAGE_USE_NO_UPDATE_CHECK=1` or the family-wide `USE_NO_UPDATE_CHECK=1` turns the check off; it is also skipped when `CI` is set. Nothing is installed until you run `upgrade`.

**On 0.23.1 or earlier?** That self-update only looked for a global `skills` and gave up when it was missing, so it cannot deliver its own fix. Bootstrap once with (installs from before the rename are registered as `chatgpt-imagegen`):

```bash
npx -y skills update chatgpt-imagegen
```

After that `image-use update` works on its own.

image-use update
image-use upgrade # 装最新版并刷新 skill
image-use upgrade --check # 只查不改:image-use 0.29.2 -> 0.30.0
image-use upgrade --json # 同上,输出 JSON
```

它会替你调用 `skills` 管理器——PATH 上有 `skills` 就直接用,没有则走 `npx`(通常都没有)。交互式运行每天最多检查一次新版并自动升级,下次运行生效;失败时会退回提醒并列出变更。`IMAGE_USE_NO_AUTO_UPDATE=1` 只关闭自动安装,`IMAGE_USE_NO_UPDATE_CHECK=1` 连检查也关闭。`--quiet`/`--no-progress` 不会在后台升级。
`upgrade`(别名 `update`)按这份安装的来路装最新的 GitHub Release——`npx skills add` 装的走 `skills update`,git clone 的走 `git pull --ff-only`,单独拷贝的脚本直接换成新版——然后刷新它找到的其他 skill 副本(Claude Code 插件,以及 `~/.agents/skills`、`~/.claude/skills`、`~/.codex/skills` 下的 clone 和拷贝)。其他命令每天最多检查一次新版,有新版就往 stderr 打一行提示。设 `IMAGE_USE_NO_UPDATE_CHECK=1` 或全家通用的 `USE_NO_UPDATE_CHECK=1` 可关闭检查,设了 `CI` 时也不检查。不运行 `upgrade` 就不会安装任何东西。

**还停在 0.23.1 或更早?** 那时的自升级只找全局 `skills`,找不到就放弃,所以它没法把这个修复本身装进来。先手动破一次局(改名前的安装在 skills 里登记的名字是 `chatgpt-imagegen`):

```bash
npx -y skills update chatgpt-imagegen
```

之后 `image-use update` 就能自己跑了。

## Error handling

**First step for any "which backend / why isn't web working" failure:** run `image-use doctor`. It reports, read-only, the CLI's own version vs. the latest on `main`, whether each backend is set up (codex token; chrome-use installed + version; relay connected; logged-in Chrome profiles), and **which one `auto` would pick** — turning a vague "no logged-in browser" into a precise checklist.

**Automatic updates.** `skills` has no scheduler of its own, so an interactive CLI run checks `main` at most once a day. When a newer version exists it invokes the same `skills update` path as the explicit command, then uses the new code on the next run. If automatic installation is unavailable or fails, it falls back to a short stderr notice that **lists what changed** since your version:

```
提示:image-use 0.14.0 可用(当前 0.12.0)。更新:image-use update
• 0.14.0:更新提示现在会列出每个新版本改了什么
• 0.13.0:新增每天一次的新版本提示…
```

It never touches stdout and is skipped under `--quiet`/`--no-progress`; `doctor` checks unconditionally and prints the same change list. To turn checking off entirely, set `IMAGE_USE_NO_UPDATE_CHECK=1`. To keep the daily check and notice but disable automatic installation, set `IMAGE_USE_NO_AUTO_UPDATE=1`. When you see the fallback notice, run `image-use update` — it runs the `skills` manager for you, through npx when `skills` isn't on PATH (it usually isn't), so it works without a global install (or re-run the self-heal `curl`).
Update notices are covered under [Upgrade](#upgrade).

## Upgrade

When any `image-use` command prints `image-use X is available`, tell the user and offer to run
`image-use upgrade` (it updates the CLI and this skill). Check without changing anything:
`image-use upgrade --check` (or `--json`). The user may also just say "升级 image-use" / "upgrade image-use".
`image-use update` and the old `chatgpt-imagegen update` do the same thing.

If the skill came from somewhere `upgrade` can't refresh:
- Claude Code plugin: `claude plugin update image-use@leeguooooo-plugins`
- Whole family: `curl -fsSL https://raw.githubusercontent.com/leeguooooo/plugins/main/upgrade-use-family.sh | sh`

Reachability: External
Exploitability: Difficult
CWE: CWE-494 — Download of Code Without Integrity Check

Pin and verify the family-upgrade script before execution.

When an agent follows this fallback, the command executes the current main-branch script with the user’s shell permissions. If an attacker compromises the repository or its branch, the script can run arbitrary commands. Pin a reviewed immutable revision and verify its integrity before execution.

🧰 Tools
🪛 SkillSpector (2.11.1)

[error] 30: [AS1] Agent Config Directory Access: Skill reads from agent configuration directories (.claude/, .codex/, .gemini/). These directories may contain API keys, personal settings, and other credentials that the skill has no legitimate need to access.

Remediation: Remove all code or instructions that access agent configuration directories (.claude/, .codex/, .gemini/). If configuration values are needed, pass them explicitly as parameters or environment variables — never read the agent's own config files.

(Agent Snooping (AS1))

[error] 77: [TM2] Chaining Abuse: Tool calls are chained to bypass individual safety checks or escalate capabilities beyond what any single tool call would allow.

Remediation: Limit tool chaining depth and validate the output of each tool before passing it to the next. Require explicit user approval for multi-step chains.

(Tool Misuse (TM2))

[error] 119: [AE1] null: Referenced artifact was not completely inspected

Remediation: Make the referenced artifact locally available and fully analyzable, or remove the reference.

(analysis-evasion (AE1))

[warning] 123: [RP1] null: npx commands without a version suffix (e.g. @1.0.0) create a rug-pull risk if the upstream server is compromised and publishes a malicious update.

Remediation: Pin the version: npx @scope/server``@1.2.3

(MCP Rug Pull (RP1))

[warning] 134: [EA2] Autonomous Decision Making: Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

Remediation: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

(Excessive Agency (EA2))

[warning] 252: [RA2] Session Persistence: Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.

Remediation: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

(Rogue Agent (RA2))

[warning] 307: [P7] Indirect Prompt Extraction: Skill contains patterns that could indirectly extract system prompts through rephrasing, translation, summarization, or side-channel techniques.

Remediation: Guard against indirect extraction by refusing to summarize, translate, or rephrase system instructions. Add explicit anti-extraction clauses.

(System Prompt Leakage (P7))

[info] 77: [SC2] External Script Fetching: Remote code is downloaded and executed. This bypasses code review and could introduce malicious code.

Remediation: Avoid downloading and executing remote scripts. Use trusted packages from PyPI/npm. If remote fetch is required, verify checksums and use HTTPS.

(Supply Chain (SC2))

[info] 323: [SC2] External Script Fetching: Remote code is downloaded and executed. This bypasses code review and could introduce malicious code.

Remediation: Avoid downloading and executing remote scripts. Use trusted packages from PyPI/npm. If remote fetch is required, verify checksums and use HTTPS.

The notice is one stderr line, checked at most once a day; `IMAGE_USE_NO_UPDATE_CHECK=1` (or the old `CHATGPT_IMAGEGEN_NO_UPDATE_CHECK`, or the family-wide `USE_NO_UPDATE_CHECK`) turns it off.
